Property and Property law

A utility model is a patent-like intellectual property right to protect inventions.[1] This type of right is available in many countries but, notably, not in the United States, United Kingdom or Canada.[1][2] Although a utility model is similar to a patent, it is generally cheaper to obtain and maintain, has a shorter term (generally 6 to 15 years), shorter grant lag, and less stringent patentability requirements.[1][3] In some countries, it is only available for inventions in certain fields of technology and/or only for products.[1] Utility models can be described as second-class patents.[4]

While no international convention requires countries to protect utility models (unlike copyright, trade marks or patents) and they are not subject to the TRIPS agreement, they are subject to the Paris Convention for the Protection of Industrial Property, which means that countries that do protect utility models are required to comply with rules such as national treatment and priority. Utility models are also available (in countries that have a utility model system) via the Patent Cooperation Treaty (PCT) system of international patent applications.[5]

Kind codes for utility models begin with U, Y, and Z for the first, second, and third levels of publication, respectively.[6]

Definition and terminology

[edit]

A utility model is a statutory exclusive right granted for a limited period of time (the so-called "term") in exchange for an inventor providing sufficient teaching of his or her invention to permit a person of ordinary skill in the relevant art to perform the invention. The rights conferred by utility model laws are similar to those granted by patent laws, but are more suited to what may be considered as "incremental inventions".[1][7] Specifically, a utility model is a "right to prevent others, for a limited period of time, from commercially using a protected invention without the authorization of the right holder(s)."[1]

Terms such as "petty patent", "innovation patent", “short-term patents”, "minor patent", and "small patent" are generally considered to fall within the definition of "utility model".[1][8][9] The German and Austrian utility model is called the "Gebrauchsmuster", which influenced some other countries such as Japan.

Requirements for grant

[edit]

Most countries having utility model laws require that the invention be new. However, many patent or utility model offices do not conduct substantive examination and merely grant the utility model after checking that utility model applications comply with formalities. This is why for a utility model the granting process is sometimes called simply registration of the utility model.[1] Furthermore, some countries exclude particular subject-matter from utility model protection. For example, in some countries, methods (i.e., processes), chemical substances, plants and animals are barred from utility model protection.[1]

Australia

[edit]

The law in Australia provided for the grant of a utility model known, between 2001 and 2021 when it was phased out, as an innovation patent.[10] From 1979 to 2001, a similar regime existed under the name "petty patent". For an innovation patent to be valid the invention claimed must be novel and involve an innovative step. An invention will lack novelty if it has already been disclosed to the public through prior publication or prior use anywhere in the world. Publication within a "grace period" of 12 months prior to the filing date of an innovation patent with the consent of the applicant is not considered to form part of the prior art for the assessment of novelty. The innovative step requirement is supposedly a lesser requirement than the inventive step required for a standard patent under Australian law. An invention will involve an innovative step if there are differences between the invention and the prior art, that make a substantial contribution to the working of the invention.

An innovation patent is granted automatically after a formalities check without substantive examination, however, infringement proceedings cannot be instituted unless and until the innovation patent has been certified, which requires a substantive examination. Examination cannot proceed until the innovation patent has been granted. Innovation patents have a maximum term of eight years subject to payment of annual renewal fees payable from the second anniversary of the date of filing. Innovation patents are available to persons outside Australia, but an Australian address for service must be provided. Innovation patent specifications must be prepared by a registered patent attorney unless the application proceeds as a Convention application or as a divisional application. Innovation patent applications cannot proceed as national phase of an international patent application (see Patent Cooperation Treaty), but can proceed as a divisional application from an international patent application that is open to public inspection.[11]

European Union

[edit]

In 1997, the European Commission proposed the harmonisation of utility model laws across all EU countries. In 1999, the proposal was updated. No agreement could be reached, and in 2006 the proposal was withdrawn.[12]

Germany

[edit]

In Germany, a utility model is considered to be new if it does not form part of the state of the art. The state of the art comprises any knowledge made available to the public by means of a written description or by use within Germany before the date relevant for the priority of the application. Description or use within the six months preceding the date relevant for the priority of the application shall not be taken into consideration if it is based on the conception of the applicant or his predecessor in title.[13]

Italy

[edit]

In Italy, a utility model (in Italian: 'Modello d'utilità') is considered to be new if it does not form part of the state of the art.[14] The state of the art comprises any knowledge made available to the public by means of a written or oral disclosure, anywhere in the World, before the filing date of the application or the priority date (if claimed). The utility model must also involve an inventive step, i.e. machines, devices or items which are claimed in the utility models must be more effective and/or easier to use than the ones according to prior art. Utility models cannot claim processes or methods. At the time of filing the application a filing fee is due which also covers the maintenance for years 1 to 4. No claim fee is provided. The Italian Patent and Trademark Office (UIBM) does not perform substantive examination of the application in order to assess novelty and inventive step of what is claimed; the examination is limited to formal requirements only. Publication occurs at 18 months from the filing date or the oldest priority date, if any; at the time of filing the application the applicant may request advance publication, which normally occurs within 90 days. In any case only bibliographic data are published after 1 month from the filing. Grant generally occurs within 2 years. The validity of an Italian utility model is ascertained by the Judge and his/her technical expert, during litigation. At the end of the fourth year from the filing of the application, a maintenance fee for the years 5 to 10 falls due. Foreign companies/residents must indicate an address of service in Italy, that may correspond to the domicile of a lawyer or, as always occurs, a chartered patent attorney.[15]

Japan

[edit]

In Japan, a utility model is considered to be new if it has not been made available to the public by means of a written description or by use before the date relevant for the priority of the application (same as for patents). Japanese utility models are not subject to substantive examination, but the owner must request one or more "reports on technical opinion" before instituting infringement proceedings.[16]

Russian Federation

[edit]

Unlike patent claims, which can be issued in Russia on processes and compositions-of-matter, Russian utility model claims are limited to devices only. Other requirements include novelty and industrial applicability. Noteworthy, although in assessing novelty any printed material anywhere in the world constitutes prior art for both utility models and patents, public use outside of Russia is considered as prior art only for patents, but not for utility models.[17]

Unlike in most other countries, having a patent and a utility model for the same invention is not allowed in Russia. However, it is possible to have a Russian utility model and a Eurasian patent for the same invention. The main advantage of a utility model in Russia is a very short prosecution time (usually, no more than 6 moths) and a low cost. The duration of a utility model is 10 years from the priority date, and this term cannot be extended (since 2014).[18]

During an infringement litigation in Russia, the doctrine of equivalence can be used with patents, but not with utility models.[19] Also, it is not possible to convert an issued patent into a utility model to avoid the revocation of the patent in the post-issuance proceedings before Rospatent or courts, although the law to correct this situation has been considered by the Duma.[20]

Spain

[edit]

In Spain, (Spanish: modelo de utilidad), when assessing inventive step, it is evaluated whether the invention is not “very obvious” to the person skilled in the art. In contrast, for patents, that requirement is defined as "obvious", which means that it is softer for utility models due to the introduction of the term "very".[21] In relation to sufficiency of disclosure and absolute novelty, the same standard is applied as for patents.

Recent changes in Spanish patent law[22] have opened the door to protect more types of inventions. The exclusions from the scope of protection of utility models are processes, inventions aimed at biological matter, and pharmaceutical substances and compositions intended for use as a medicament in human or veterinary medicine.[23]

Utility model

View on Grokipedia
from Grokipedia
A utility model is a form of protection that grants inventors exclusive rights to prevent others from commercially exploiting minor technical inventions or incremental improvements to existing products, typically for a limited period. Unlike standard patents, utility models generally require a lower level of inventiveness, involve simpler registration procedures without substantive examination in most jurisdictions, and offer shorter protection terms ranging from 6 to 15 years, making them a faster and more affordable option for safeguarding smaller innovations. Utility models are recognized in over 60 countries and regional systems worldwide, including key economies such as , , , , and the African Regional Intellectual Property Organization (ARIPO) as well as the Organisation Africaine de la Propriété Intellectuelle (OAPI), but they are not available in jurisdictions like the or the , where equivalent protection is sought through utility patents or other mechanisms. Originating as an alternative to full patents to encourage among small inventors and businesses, utility models often apply specifically to the shape, configuration, or construction of articles rather than processes, and their territorial nature means protection is limited to the country of registration. The system promotes economic and technological development by lowering barriers to IP protection, with official fees and processing times significantly reduced compared to patents—often obtainable in under six months—thus enabling quicker market entry for modest inventions. However, rights holders must still meet basic criteria of novelty and industrial applicability, and enforcement relies on national laws, without a dedicated international treaty like the for patents.

Definition and scope

Core definition

A utility model is a registered form of protection that grants the holder an exclusive right to prevent others from commercially exploiting a technical invention, typically focusing on minor or incremental improvements to existing products. Unlike standard patents, utility models feature less stringent requirements, including a lower threshold for novelty—often limited to local novelty in some s—and a reduced or absent inventive step, making them suitable for protecting simpler innovations. Requirements, including the level of inventive step, vary by . Key characteristics of utility models include a shorter duration of protection, generally ranging from 6 to 15 years from the filing date, often non-extendable beyond a maximum term but renewable in some jurisdictions up to that limit; a streamlined and faster registration process that is often cheaper and may lack substantive examination; and an emphasis on the shape, construction, or configuration of articles of manufacture rather than processes. This form of protection is particularly advantageous for incremental technical solutions that do not meet the higher standards of full patents. The terminology "utility model" derives from national equivalents, such as the German Gebrauchsmuster—literally meaning "model for use" or "utility pattern"—and the Italian modello di utilità or brevetto per modelli di utilità, reflecting its origins in protecting practical, functional aspects of . Notably, this differs from the " patent" , which denotes a conventional for the functional features of an invention and not a distinct, lower-threshold right like utility models in other countries.

Protected subject matter

Utility models protect technical inventions that constitute minor or incremental improvements to existing products, particularly those involving the , , or configuration of devices, tools, articles of manufacture, or their functional components such as mechanisms and compositions. These eligible subject matters are generally limited to tangible products with practical , emphasizing physical embodiments over abstract concepts, though specifics vary by . In many jurisdictions, utility model protection is suited for innovations that enhance functionality without requiring groundbreaking novelty, such as adaptations that improve efficiency or usability in everyday applications. Common examples of protected subject matter include modifications to household appliances, like an improved handle design for a that enhances grip and durability; simple mechanical tools, such as a novel ratchet mechanism in a for better application; and packaging innovations, for instance, a resealable that prevents spillage while maintaining product freshness. These illustrations highlight how models safeguard practical, - or construction-related enhancements in mechanical devices and apparatus, which are often granted faster and at lower cost than full patents. Certain categories are explicitly excluded from utility model to delineate its scope from other rights, with exclusions varying by country but often similar to those for patents. Abstract ideas, scientific discoveries, and mathematical methods lack the technical character required for eligibility, as they do not involve concrete implementations. Methods of treatment, including surgical, therapeutic, or diagnostic procedures practiced on the or body, are also ineligible, along with software as such when it consists merely of computer programs without tied hardware integration. Aesthetic are excluded unless they incorporate functional elements, such as a tool's ergonomic shape that affects performance; pure ornamental aspects fall under protection instead. Additionally, in various countries, processes (especially chemical or biological ones), plant varieties, breeds, and inventions contrary to public order or morality are barred. To qualify, the invention must demonstrate technical character—meaning it solves a technical problem through physical means—and be new, though the threshold for inventiveness is lower than for patents, often requiring only a modest step beyond . This focus ensures utility models target industrially applicable solutions with clear, functional benefits, excluding non-technical or purely theoretical advancements.

Historical background

Origins and early adoption

The utility model, known as "Gebrauchsmuster" in German, originated in Imperial Germany with the Utility Model Protection Law of 1891 amid the , when rapid technological advancements necessitated accessible protections for incremental innovations. This system was established to safeguard minor inventions, particularly practical improvements to tools and devices that did not warrant full examination. It addressed the growing demand for swift, low-cost registration to encourage small-scale inventive activity without the rigorous scrutiny and expenses associated with traditional patents. The underlying rationale for these early utility models was to empower small and medium-sized enterprises (SMEs) and individual inventors, who often lacked the resources for lengthy processes, by providing affordable and expedited safeguards against imitation during the era's intense competitive industrialization. This approach democratized access to , promoting widespread participation in technological progress while complementing the more stringent regime for groundbreaking inventions. An early international adoption occurred in in 1905, where the system was modeled after the German framework to protect petty inventions.

Modern evolution and expansion

Following , Germany's utility model system was re-established as part of the broader reconstruction of its framework, with the German Patent Office resuming operations in in 1949 under the Act of 12 August 1949. By the mid-1950s, reforms aligned the system more closely with emerging international standards, including those from the Paris Convention for the Protection of Industrial Property, facilitating economic recovery through streamlined protection for minor technical inventions. In , the utility model regime, originally enacted in 1905 and modeled after the German system, underwent significant evolution during the 20th century, culminating in the 1990s with key amendments such as the shift to a non-examination registration process in 1993, which expedited protection for incremental innovations to support rapid industrialization. The expansion of utility model protection extended to and beyond in the late , reflecting growing recognition of its role in fostering in developing economies. introduced its utility model system in 1985 alongside the inaugural Patent Law, targeting "small inventions" to address imbalances in technological development and encourage domestic manufacturing. enacted the Utility Model Act in 1961, building on earlier provisions to provide faster registration for practical devices amid its high-tech export boom, with significant amendments in the late 1990s. In , the post-Soviet Patent Law of 1992 established utility model protection for the first time, defining it as a registrable right for implementable to transition from centralized to market-driven . On the international front, the Agreement on Trade-Related Aspects of Rights (TRIPS), effective from 1994, indirectly shaped utility model regimes by mandating compliance with the Paris Convention's minimum standards, including national treatment and priority rights for utility models, though it imposed no specific obligations on their substantive requirements. Efforts toward harmonization within the faltered, as a Commission proposal for a directive approximating utility model protection—initially presented in 1997 and amended in 1999—was suspended in 2000 and formally withdrawn in 2006 due to disagreements among member states over scope and examination procedures. In recent decades, utility model systems have adapted to the digital age by safeguarding incremental technical enhancements in and tech gadgets, such as improved mechanical components in smartphones or wearable devices, where rapid market entry demands swift, low-cost IP safeguards. This evolution is evidenced by sustained filing activity; for instance, recorded approximately 9,709 utility model applications in 2023, underscoring the regime's ongoing relevance for European innovators in dynamic sectors like and .

Relation to other intellectual property

Comparison with patents

Utility models and patents share several fundamental similarities as forms of protection for technical inventions. Both grant the holder exclusive to prevent unauthorized commercial exploitation of the protected subject matter within a defined , typically requiring registration with a national or regional intellectual property office. Applications for both must include a detailed disclosure, such as claims, descriptions, drawings, and abstracts, to ensure the is sufficiently described for understanding and replication. Enforcement of under both systems occurs through judicial processes, where infringement can lead to remedies like injunctions or . Despite these parallels, utility models differ from patents in key aspects designed to provide quicker and more accessible protection for minor innovations. Utility models generally impose a relaxed inventive step requirement, often described as a "simple" improvement rather than the "non-obvious" advancement needed for patents, making them suitable for incremental changes. Their term of protection is shorter, typically ranging from 6 to 15 years from the filing date, with some jurisdictions allowing renewals or extensions, compared to the standard 20-year term for patents. In many jurisdictions, utility models undergo no substantive examination prior to grant, relying instead on formal checks and post-grant challenges, which contrasts with the rigorous pre-grant examination required for patents. This results in faster granting times for utility models, often within months, versus several years for patents. The scope of protection under utility models is generally narrower than that of patents. Utility models are often restricted to tangible products, such as mechanical devices or apparatus, and exclude processes or methods, whereas patents can cover a broader range including methods and chemical compositions. This limitation aligns with their focus on practical, shape- or structure-related improvements rather than complex technological breakthroughs. Certain inventions may qualify for protection under both utility models and patents, leading to strategic filing decisions based on the applicant's needs. Inventors might opt for a utility model to secure rapid, low-cost interim protection—significantly cheaper due to reduced fees and no examination costs—while pursuing a parallel or subsequent for longer-term coverage. In some systems, utility model applications can even be converted into applications if stronger protection is deemed necessary. This overlap allows flexibility but requires careful assessment to avoid conflicting claims or unnecessary duplication.

Distinctions from petty patents and designs

Utility models and petty patents are closely related forms of protection, with the term "petty patent" often serving as a for utility model, particularly in historical contexts in English-speaking countries such as the , where it referred to a short-term right for minor inventions until the early . In some jurisdictions, however, petty patents have been distinct, such as Australia's innovation patent system, which provided provisional protection for incremental innovations with minimal substantive examination and a maximum term of eight years, but was phased out with no new filings accepted after , 2021. By contrast, utility models in countries like and , as well as in Asian jurisdictions such as , , and , are formal registered rights that undergo registration with potentially limited or no substantive examination, offering standardized short-term protection typically ranging from 6 to 15 years to encourage rapid commercialization of minor technical solutions. While both petty patents and utility models target less complex inventions than standard and provide quicker, lower-cost protection, utility models demonstrate greater international standardization through frameworks like those administered by the (WIPO). In distinction from industrial designs, utility models focus exclusively on the functional and technical aspects of an , such as improvements in , , or mechanism that enhance , whereas industrial designs protect only the ornamental or aesthetic features of a product's appearance, like its visual design or pattern. This separation ensures no overlap in scope: for instance, the functional grip and pipette mechanism in a fountain pen ink injection system could qualify for utility model protection due to its technical efficiency, but the pen's external styling would instead fall under rights. Utility models thus emphasize practical benefits, such as enhanced usability or performance, without extending to purely decorative elements that do not contribute to the item's operation. Utility models uniquely bridge the protective gap between full —which require higher inventiveness—and industrial designs, making them suitable for hybrid inventions where functional predominates but aesthetic elements may also be present; protection applies solely to the technical features. A representative example is a foldable handle for a compact shelf, where the mechanical folding structure improves storage efficiency and portability, qualifying for utility model registration in jurisdictions like without covering the handle's visual form. This positioning allows inventors to secure affordable, expedited rights for everyday technical enhancements that might not meet thresholds but exceed mere ornamental changes.

General requirements for protection

While the following outlines general requirements, specifics vary by .

Novelty and inventive step

Novelty is a fundamental requirement for utility model , which may demand absolute worldwide novelty or, in some countries, only local novelty, meaning the invention must not have been disclosed publicly (anywhere or locally) prior to the filing date. However, many jurisdictions provide a of 6 to 12 months, allowing disclosures by the inventor or applicant—such as at trade shows or in publications—without destroying novelty, provided the application is filed within that timeframe. The inventive step criterion for utility models is generally less rigorous than for patents, often requiring only a minimal degree of non-obviousness or, in some systems, none at all, where industrial applicability alone may suffice. Unlike patents, which demand that the not be obvious to a person skilled in the art, utility models can protect innovations that might appear straightforward, such as those involving small functional enhancements that yield practical benefits. Assessment of novelty and inventive step relies on a prior art search to evaluate the against existing knowledge, with validity often confirmed through post-grant challenges rather than substantive examination. Qualifying examples include minor efficiency tweaks, like an ergonomic handle on a tool that improves grip without altering core functionality, or a simple mechanical adjustment to a device that enhances . Exceptions to protection arise for obvious combinations of known elements that produce no unexpected results or for mere discoveries of natural phenomena, which lack the technical character required for utility model eligibility.

Industrial applicability and disclosure

For a utility model to be eligible for , the must demonstrate industrial applicability, meaning it is capable of being made or used in any kind of industry, including . This requirement ensures the subject matter is practical and exploitable on a technical or economic scale, excluding purely theoretical concepts, scientific discoveries, mathematical methods, aesthetic creations, and schemes, rules, or methods for performing mental acts, playing games, or doing business. Unlike speculative ideas that may hinder future , industrially applicable inventions must offer concrete utility in their disclosed form, often focusing on devices, apparatus, or products that can be manufactured or applied repetitively. Disclosure requirements form a core prerequisite for utility model registration, mandating that the application fully and accurately reveal the invention to the public in exchange for exclusive rights. The application must include a request for protection, a clear and complete technical description of the invention, one or more claims defining the scope of protection, an abstract, and drawings where necessary to illustrate the invention. The description must be sufficiently detailed to enable a person skilled in the art to carry out the invention—replicating it without undue experimentation—ensuring the sufficiency of disclosure and preventing later additions of undisclosed technical features that could extend the original scope. In many jurisdictions, utility model claims adhere to formal standards that emphasize physical embodiments over abstract functionalities, typically limiting protection to the shape, structure, or specific configuration of tangible products rather than processes or methods; however, some countries (e.g., ) allow method claims. For example, a claim for a new gear configuration must detail its physical arrangement, materials, and mechanical interactions to demonstrate how it operates within a device, rather than solely asserting its efficiency improvements or functional advantages. This structural focus aligns with the exclusion of non-physical solutions, reinforcing the requirement that the invention be a , replicable technical improvement.

Protection process and duration

Filing and examination procedures

The filing process for a utility model begins with submission of an application to the relevant national or regional intellectual property office, following the first-to-file principle. The application typically includes a request form, description of the invention, claims defining the scope of protection, drawings if necessary, and an abstract. Filing fees are generally low compared to patents, ranging from approximately $50 to $500 depending on the jurisdiction, with no separate examination fee in most cases. Note that procedures and fees may vary and have been recently updated in some jurisdictions, such as South Korea (2025 amendments) and OAPI (January 2025). Examination procedures for utility models are streamlined and often limited to formal checks for completeness and compliance with basic administrative requirements, without a substantive of novelty or inventive step at the initial stage. In some jurisdictions, such as , applicants may optionally request a registrability examination that includes a preliminary novelty assessment to evaluate potential validity issues. This contrasts with examination, which involves comprehensive substantive searches. Due to the absence of substantive examination, utility models are typically granted within 1 to 6 months from filing, significantly faster than the 2 to 5 years often required for patents. Post-grant opposition by third parties is possible in many systems, allowing challenges to validity through administrative or judicial proceedings. Maintenance fees to keep the utility model in force generally become due annually starting after the third to sixth year of protection, with amounts increasing over time; for example, in , the first renewal fee of about €210 (approximately $230) is payable at the beginning of the fourth year. Many European countries, such as , , and , offer streamlined online filing systems to facilitate electronic submission and payment.

Term of protection and maintenance

The term of protection for a utility model generally ranges from 6 to 15 years from the filing date and cannot be extended, unlike many systems that allow for supplementary protection certificates or adjustments in specific fields such as pharmaceuticals. For instance, in , the maximum duration is 10 years from the filing date. In , protection also lasts 10 years from filing, with a single maintenance fee due at the fifth year to cover the second half of the term. Maintaining a utility model requires payment of annual annuity fees to the relevant intellectual property office, with amounts escalating over time to reflect administrative costs. Non-payment leads to lapse of the protection, typically after a with surcharges; for example, in , fees unpaid by the end of the result in expiration unless rectified. Many jurisdictions permit reinstatement within 6 months of lapse if the delay is deemed unintentional, upon submission of a , the overdue fees, and any applicable penalties. Upon expiration at the end of the term or due to lapse without reinstatement, the protected enters the , enabling unrestricted commercial exploitation by third parties. Utility models do not trigger compulsory licensing requirements upon expiration, unlike certain regimes where such licenses may be mandated prior to term end for failure to work the sufficiently.

Availability by jurisdiction

European countries

In Europe, utility model protection is not harmonized at the European Union level, with systems operating independently in national jurisdictions rather than through a centralized EU framework. Although the European Commission proposed harmonization in 1997 following consultations, the initiative was abandoned due to lack of agreement among member states. As a result, utility models are available in approximately 15 EU member states, including Austria, Belgium, Bulgaria, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Italy, Lithuania, Portugal, Slovakia, and Spain, alongside non-EU countries such as Switzerland and Turkey. These national regimes typically protect minor technical inventions, such as improvements in shape, configuration, or construction, that meet requirements of novelty and industrial applicability but often require a lower level of inventive step than full patents. Germany maintains one of the most prominent utility model systems in Europe, known as the Gebrauchsmuster, offering a maximum term of protection of 10 years from the filing date with no substantive examination, only formal checks, allowing registration in as little as . In 2023, the German and (DPMA) received 9,709 utility model applications (as of 2024 data, 9,064 applications were received), underscoring its popularity for rapid, cost-effective protection. Italy's utility model, or modello di utilità, also provides 10 years of protection and emphasizes functional innovations in products or machines as a whole, with applications filed through the Italian and (UIBM) or local chambers of ; in 2024, it granted 1,273 such models, representing about 72% of its final patent-related decisions. Spain's system, administered by the Spanish and (OEPM), similarly offers a 10-year term with an accelerated grant procedure that can conclude in under a year, focusing on inventions with evident practical utility; in 2023, it received 2,807 applications. In , the traditional utility model was reformed into the certificat d'utilité under the 2020 PACTE law, extending the term to 10 years (from a previous maximum of 6 years) without substantive examination, enabling quick registration for technical inventions; around 890 applications were filed in 2023. The , however, discontinued its utility model system following the Utility Designs Act of 1843, replacing it with standard patent protection after 1978, and currently offers no dedicated utility model regime. Common features across European utility model systems include low filing fees, typically ranging from €30 in to €100 in , making them accessible for small and medium-sized enterprises (SMEs). Applications are processed through central national registries, such as patent offices, with post-2000 reforms introducing digital filing options; for instance, 76.2% of German utility model applications in 2024 were submitted electronically. Across the , utility model grants totaled approximately 15,000 to 20,000 annually in the early 2020s (as of 2023 data), driven largely by filings in , , and , and playing a key role in safeguarding incremental innovations for SMEs that may not justify the cost and time of full patents.

Asian and Pacific jurisdictions

Utility models play a significant role in Asian and Pacific jurisdictions, particularly in manufacturing powerhouses where rapid protection for incremental technical improvements is valued. These systems typically feature shorter terms and lower inventive step requirements than standard patents, facilitating quick registration and enforcement for devices, shapes, or structures in industries like and machinery. High filing volumes reflect their utility in emerging markets, with alignment to international standards post-TRIPS Agreement enhancing accessibility and integration into global supply chains. In , the utility model system, dating back to 1905, protects inventions related to the shape, structure, or combination of articles, offering a 10-year term from the filing date. Applications undergo only formal examination without substantive review of novelty or inventive step, enabling registration in as little as 2-4 months, a shift implemented in to streamline protection for minor innovations. This approach suits tweaks, such as enhancements in electronic components, where speed outweighs extensive scrutiny. China's utility model regime, established under the 1984 Patent Law and effective from 1985, safeguards technical solutions concerning the shape, structure, or their combination in products, with a fixed 10-year term from filing and preliminary examination focused on formalities and basic novelty. The system has experienced explosive growth, driven by manufacturing demands, with 2.927 million applications filed in 2020—representing over 97% of global utility model filings—and cumulative totals exceeding 20 million by the early 2020s. Utility models require a comparatively low inventive step, making them ideal for iterative developments in high-tech sectors, and they support technology dissemination via the through dedicated accelerated examination programs for partner countries. South Korea maintains a robust utility model framework under the Utility Model Act, providing 10-year protection from filing for novel, industrially applicable devices with an inventive step akin to but lower than patents. A distinctive feature is the optional technical evaluation report issued upon request, which assesses to aid enforcement without delaying registration, typically completed in under a year. This tech-oriented system is prominent in and automotive , where it enables swift safeguarding of functional improvements. Australia's innovation patent, introduced in 2001 as a utility model equivalent, granted 8-year protection for inventions meeting an "innovative step" threshold below that of standard patents, with rapid certification after formal checks. However, the system was phased out to align with international norms, ceasing new filings on August 26, 2021, though existing rights persist until expiry, with the last potentially ending in 2029. This discontinuation reflects a shift toward a unified patent regime emphasizing higher innovation standards. Across these regions, utility models thrive in hubs due to their emphasis on lower inventive hurdles and expedited processes, contrasting with more rigorous European systems by prioritizing volume and speed to bolster economic competitiveness in emerging markets. Post-TRIPS reforms have standardized protections, promoting cross-border innovation while examples like Japanese modifications highlight their practical application in iterative product development.

Other regions and international aspects

In the , utility model protection is limited to select jurisdictions. provides protection for utility models under its Industrial Property Law, granting a term of up to 15 years from the filing date. also offers utility model registration, typically for a 10-year term, though its system emphasizes minor improvements to existing inventions. In contrast, the does not recognize utility models as a distinct right, instead relying on provisional applications to provide temporary protection for inventions before full utility examination. Utility model systems are rare in Africa and the Middle East, with most countries relying solely on standard patents. Russia introduced utility model protection in 1992 through amendments to its intellectual property framework, offering a term of 10 years from the filing date without extension. South Africa lacks a dedicated utility model regime, protecting functional aspects of inventions through patents or registered designs instead. Turkey, aligned with European standards due to its customs union with the EU, grants utility model protection for 10 years from the application date, focusing on technical improvements with simplified registration. Internationally, utility models benefit from the Paris Convention for the Protection of Industrial Property, which allows applicants to claim a 12-month priority period when filing in member states, treating utility models equivalently to patents for this purpose. Unlike the (PCT), which facilitates international patent filings but does not have a direct equivalent for utility models, protection must be pursued nationally or regionally in countries offering the system; however, PCT applications can sometimes designate utility model protection where available. According to WIPO data, more than 80 countries provide protection as of 2023, primarily in , , and parts of , though global filings remain dominated by a few key offices. Notable gaps exist in the global landscape, including abolishments in certain jurisdictions; for instance, some European countries like discontinued substantive examination for utility models in the 1990s before later reforms, reflecting shifts toward streamlined patent systems. Proposals for greater harmonization have been advanced through the Patent Law Treaty (PLT), administered by WIPO, which standardizes formalities for filing and maintenance of applications, including those for utility models, to reduce administrative burdens across borders.

Advantages and limitations

Benefits for inventors

Utility models offer inventors a cost-effective means of protection, with official fees and maintenance costs generally ranging from 20% to 50% of those associated with standard invention . This affordability is particularly advantageous for startups, small and medium-sized enterprises (SMEs), and individual inventors who may lack the resources for more expensive filings. For instance, in , the full process cost for a utility model is approximately 50% that of an invention , making it accessible for resource-constrained innovators. The rapid registration process of utility models enables inventors to secure protection quickly, often without substantive examination, allowing for swift market entry in sectors with short product lifecycles such as consumer goods. In jurisdictions like , utility models can be granted in 6 to 12 months, compared to 1 to 4 years for patents, providing timely safeguards for incremental improvements. This speed helps inventors capitalize on fleeting commercial opportunities before competitors can replicate their innovations. Strategically, utility models serve as defensive tools to block competitors from obtaining similar rights or as a stepping stone to fuller protection, enabling cumulative IP strategies where initial utility model filings secure early rights while pursuing broader applications. They allow inventors to layer protections for evolving technologies, such as filing multiple utility models for product variants, thereby enhancing overall portfolio resilience without prohibitive expenses. In developing economies, utility models foster by encouraging local inventors and SMEs to protect minor technical advances, contributing to industrial growth and technological . For example, China's utility model has supported sectors, including tool producers, by enabling rapid protection of practical improvements, with over 648,000 applications filed between 1994 and 2003, predominantly by domestic entities. This has boosted economic competitiveness in incremental innovation-driven industries.

Criticisms and challenges

Utility models have faced criticism for potentially protecting low-quality inventions due to their minimal or absent substantive pre-grant examination in many jurisdictions. This registration-based approach, which often skips rigorous novelty and inventiveness checks, can result in the granting of rights over obvious or marginally innovative technical solutions, leading to legal uncertainty and excessive litigation for third parties. For instance, in , where utility models undergo only preliminary examination, over 80% of applications are granted within a year, contributing to a of diminished patent quality. Such systems may undermine the overall integrity of rights by blurring the boundary between protectable inventions and knowledge. Another concern is the potential for utility models to contribute to "patent thickets," dense webs of overlapping that can block subsequent , particularly in crowded fields. The proliferation of narrow, low-threshold utility model protections, often held by multiple owners, can create rights congestion and anti-commons effects, complicating licensing and deterring efforts. This issue is exacerbated in jurisdictions with high filing volumes, where fragmented ownership increases the risk of hold-up problems for innovators navigating the thicket. Enforcement of utility models presents additional challenges, including their shorter protection terms, which limit long-term commercial value compared to standard patents. The lack of pre-grant scrutiny also heightens post-grant invalidation risks, as rights holders may face nullity actions or court challenges revealing prior art or lack of novelty. In Germany, for example, utility models cannot be opposed administratively but are vulnerable to cancellation proceedings at the German Patent and Trade Mark Office or nullity suits at the Federal Patent Court, where validity risks are significant due to the unexamined nature of the grants. Similarly, in China, invalidation requests against utility models succeed at rates exceeding 60%, reflecting the system's propensity for weak rights. Debates surrounding utility models often center on their overuse in Asian jurisdictions, particularly , where filings have surged to over 2 million applications in a single year, fostering "spam" registrations with unreasonably broad claims that encompass . This volume enables opportunistic enforcement, such as third-party filings mimicking existing products to sue original manufacturers, thereby increasing infringement risks for businesses and straining judicial resources. In the , efforts to introduce a harmonized utility model system via a 1997 directive proposal were abandoned in 2006, as stakeholders failed to reach consensus amid shifting priorities toward a framework, which promised broader harmonization benefits despite associated implementation costs. Some countries have responded to these issues by abolishing utility model systems or shifting toward standard utility patents. , for instance, phased out its innovation patent regime—functionally similar to utility models—in 2021, following reviews that highlighted its net economic costs, low-quality grants, and limited benefits for . Looking ahead, reforms are underway in key jurisdictions to mandate more rigorous examination; implemented a preliminary review for "obvious lack of inventiveness" in utility models effective January 20, 2024, as part of the amended Implementing Regulations of the Law, aiming to curb abuse while preserving accessibility. Following implementation, utility model grants in decreased by 25.5% in 2023 compared to 2022, with further declines to approximately 2 million grants in 2024 and continued reductions in 2025, indicating a shift toward higher quality protections.
