1. Introduction

The German utility model (Gebrauchsmuster) is often described as a “small patent”. Although this description reflects its historical origins, it no longer adequately captures the legal character of the German utility model.

Originally introduced in the late nineteenth century as a form of protection for the historically so-called “minor inventions” (kleine Erfindungen), the German utility model has long been associated with the notion of a “small patent”.

However, viewing the German utility model merely as a patent with faster registration or a shorter term of protection misses the point. It is an independent industrial property right with its own legal framework and distinctive procedural features.

This article provides an overview of the principal features of the German utility model. Rather than offering a provision-by-provision commentary on the German Utility Model Act (Gebrauchsmustergesetz), it explains the legal system underlying the utility model, drawing on the Act itself, the practice of the German Patent and Trade Mark Office (DPMA), and the German case law.

2. What Can a German Utility Model Protect?

Like a German patent, a German utility model protects technical inventions. As a general rule, it must satisfy the requirements of novelty, inventive step (erfinderischer Schritt), and industrial applicability.

A major difference from patent law, however, is that methods (Verfahren) are excluded from utility model protection under Section 2 No. 3 of the German Utility Model Act. As a result, only products, but not methods as such, are in principle eligible for protection.

The distinction between a product and a method cannot be determined solely by the wording of a claim. Rather, the decisive question is what the claim actually seeks to protect.

In Signalfolge (X ZB 9/03), Arzneimittelgebrauchsmuster (X ZB 7/03), and Telekommunikationsanordnung (X ZB 23/07), the German Federal Court of Justice clarified that neither functional features, program-related features, nor purpose-related limitations automatically transform a claim into an unprotectable method claim. What matters is whether the claimed subject matter is directed to a product or to a method.

This case law has considerable practical significance. Although method claims cannot themselves be protected as utility models, the same technical teaching can often be claimed in the form of a product claim—for example, as a device, system, or another technical product. This is not merely a matter of redrafting the claims, but of redefining the protected subject matter and, consequently, the scope of protection.

3. Why Can a German Utility Model Be Registered So Quickly?

Perhaps the most distinctive feature of the German utility model is that it is registered without substantive examination.

Once an application has been filed, the German Patent and Trade Mark Office (DPMA) examines only whether the formal requirements have been met and whether the claimed subject matter is, in principle, eligible for utility model protection. Novelty, inventive step, and industrial applicability are generally not examined before registration.

This absence of substantive examination explains why a German utility model can often be registered within only a few weeks. It does not, however, mean that the substantive requirements for protection are any less demanding. Like a patent, a utility model must satisfy the requirements of novelty, inventive step, and industrial applicability; the difference lies solely in the timing of their examination.

Whether those requirements are actually fulfilled is therefore normally determined only if the validity of the utility model is challenged in cancellation proceedings or raised in infringement proceedings.

4. Is the Standard of Protection Really Different?

Some readers may notice that the German Utility Model Act uses the term “inventive step” (erfinderischer Schritt), whereas the German Patent Act refers to “inventive activity” (erfinderische Tätigkeit). Does this mean that utility models are subject to a lower standard of inventiveness?

The German Federal Court of Justice (BGH) answered this question in its Demonstrationsschrank decision (X ZB 27/05). The Court made clear that, in assessing inventiveness, the key distinction does not lie in a different standard of inventiveness, but rather in the scope of the prior art.

For German patents, prior art generally includes all information made available to the public before the filing date, whether through written or oral disclosure, public use, or any other means. The scope of the prior art is narrower for German utility models. In principle, only written disclosures worldwide and public use within Germany form part of the prior art. In addition, German utility models benefit from a six-month grace period (Neuheitsschonfrist).

Accordingly, the same invention may sometimes be assessed differently under the German patent and utility model systems. The reason, however, is usually not a different standard of inventiveness, but the different scope of the prior art on which the assessment is based.

5.Abzweigung: a Strategic Feature of the German Utility Model

If German patent practitioners had to identify one feature that truly distinguishes the German utility model, many would probably not point to the lack of substantive examination or the six-month grace period. Instead, they would point to the Abzweigung procedure.

At first sight, Abzweigung appears to be little more than a procedural mechanism. It allows an applicant to derive a German utility model from a pending German patent application, a European patent application, or a PCT application designating Germany. Its real significance, however, lies in solving a practical problem of timing.

Obtaining a patent often takes several years. During that period, the applicant already enjoys a filing date and, where applicable, a priority date, but does not yet possess an enforceable registered right. Commercial reality, however, rarely waits. Competitors may already have entered the market, products may have been launched, and important business opportunities may already have passed.

This is precisely where the Abzweigung procedure becomes valuable. Because a German utility model is registered without substantive examination, it enables the applicant to obtain an enforceable registered right much more quickly, while retaining the filing date and any valid priority claim of the original patent application.

In other words, the procedure does not restart the application process. Instead, it creates a separate utility model that preserves the temporal priority of the original patent application.

For that reason, Abzweigung is far more than a procedural technicality. In practice, it allows applicants to defer the decision whether to obtain an immediately enforceable right until market developments make such protection commercially desirable.

6. Review of Validity in Infringement Proceedings and Cancellation Proceedings

One distinctive feature of the German utility model system is that the validity of a registered utility model may be examined both in cancellation proceedings (Löschungsverfahren) and in infringement proceedings, although the two proceedings serve different functions.

Because a German utility model is generally registered without substantive examination, registration does not itself establish that the statutory requirements for protection, such as novelty and inventive step, have been satisfied. When an infringement dispute arises, the alleged infringer may challenge the utility model not only by initiating separate cancellation proceedings but also by arguing in the infringement action that the statutory requirements for protection were never fulfilled and that the registration did not establish utility model protection. The infringement court may examine those issues to the extent necessary for deciding the infringement dispute (BGH, Momentanpol I, X ZR 226/00; OLG Düsseldorf, Fondant, 2 U 74/23, Rn. 52; OLG Düsseldorf, Fremdkörpersammel- und Metrologievorrichtung, 2 U 29/24, Rn. 454).

Such review serves only to resolve the particular infringement dispute. Unlike cancellation proceedings, it does not result in a decision with erga omnes effect as to whether, or to what extent, the utility model should continue to exist. Even if the infringement court concludes that the statutory requirements for protection are not fulfilled, the utility model is not automatically removed from the register. Only separate cancellation proceedings may produce such an effect.

This also distinguishes the German utility model from the German patent. Under the German patent system, the validity of a patent is, as a matter of principle, determined only in separate nullity proceedings. By contrast, the statutory requirements for protection of a German utility model may also be examined in infringement proceedings. Whether the registered right continues to exist, however, remains a matter exclusively for cancellation proceedings.

7. Concluding Remarks

The German utility model is often described as a “small patent.” While this label is convenient, it does not fully capture the nature of the system.

Rather than being a simplified version of a patent, the German utility model is an independent intellectual property right with its own legal framework and procedural design. Its significance lies not in lowering the standards for protection, but in providing a distinct mechanism for protecting technical innovations.

For anyone seeking patent protection in Germany, the utility model should therefore not be regarded merely as a cheaper or faster alternative to a patent. Instead, it is a complementary form of protection with its own procedural features and practical significance.
