German Intellectual Property Law
Overview of German Intellectual Property Law
German intellectual property law is a comprehensively codified system that operates within the framework of European Union harmonisation while maintaining distinct national features. The primary statutes include the Patent Act (Patentgesetz — PatG), the Utility Model Act (Gebrauchsmustergesetz — GebrMG), the Copyright Act (Urheberrechtsgesetz — UrhG), the Trade Mark Act (Markengesetz — MarkenG), the Design Act (Designgesetz), and the Act Against Unfair Competition (Gesetz gegen den unlauteren Wettbewerb — UWG). The German Patent and Trade Mark Office (Deutsches Patent- und Markenamt — DPMA), headquartered in Munich, administers patents, utility models, trade marks, and designs.
Patent Law
The Patent Act (Patentgesetz)
German patent law is governed by the PatG, which is substantively aligned with the European Patent Convention. The requirements for patentability under § 1 PatG are novelty, inventive step (Erfindungshöhe), and industrial applicability (gewerbliche Anwendbarkeit). Excluded subject matter includes discoveries, scientific theories, mathematical methods, aesthetic creations, schemes and methods for mental acts or business, computer programs as such, and presentations of information, mirroring the EPC exclusions.
Novelty and Inventive Step
Novelty under § 3 PatG requires that the invention not form part of the state of the art before the priority date. The state of the art includes everything made available to the public by written or oral description, use, or any other means. Non-prejudicial disclosures include those made in breach of confidentiality or at officially recognised international exhibitions.
Inventive step requires that the invention not be obvious to a person skilled in the art. The German courts apply the problem-solution approach derived from EPO practice, identifying the closest prior art, the objective technical problem, and whether the claimed solution would have been obvious. The skilled person is a hypothetical practitioner with knowledge of the common general knowledge in the field.
Application and Examination by the DPMA
Patent applications are filed with the DPMA, which conducts formal examination and, upon request, substantive examination. An application includes the request for grant, description, claims, drawings where necessary, and an abstract. Examination is conducted by patent examiners qualified in the relevant technical field. The DPMA publishes the application 18 months after filing and grants the patent upon satisfaction of all requirements.
Opposition Procedure
Within nine months of grant, any person may file an opposition (§ 59 PatG) on grounds including lack of patentability, insufficiency of disclosure, and unallowable extension of subject matter. Opposition proceedings before the DPMA Patent Division provide an administrative avenue for challenging validity before resorting to the Federal Patent Court (Bundespatentgericht).
Patent Term and Employee Inventions
The patent term is 20 years from the filing date (§ 16 PatG), subject to annual renewal fees. Supplementary protection certificates (SPCs) extend patent protection for pharmaceutical and plant protection products for up to five years.
Employee inventions are governed by the Employee Invention Act (Arbeitnehmererfindungsgesetz — ArbEG), which requires employees to disclose inventions made during employment. The employer may claim the invention by written declaration, in which case the employee receives reasonable compensation calculated according to a statutory remuneration guideline, unless the parties agree on a lump sum payment.
Infringement
Patent infringement (Patentverletzung) under § 139 PatG entitles the patentee to injunctive relief (Unterlassungsanspruch), damages (Schadensersatzanspruch), and account of profits (Herausgabe des Gewinns). The German courts apply a three-pronged damages calculation: the patentee may elect between the infringer’s actual profits, the patentee’s lost profits, or reasonable royalties. The doctrine of equivalents applies, with infringement established when the accused embodiment solves the problem underlying the invention with means that have the same technical effect using considerations of function, obviousness, and equivalence of the modified means.
Utility Models
The Gebrauchsmustergesetz protects utility models (Gebrauchsmuster) as a lesser form of patent protection available for inventions in all technical fields except processes and methods. The requirements are novelty, inventive step, and industrial applicability, though the inventive step threshold is lower than for patents. Utility models are registered without substantive examination and have a maximum term of 10 years (initial three years, renewable for two additional periods of three and four years). The registration procedure is expedited, making utility models attractive for protecting innovations with short commercial lifespans.
Copyright Law
The Copyright Act (Urheberrechtsgesetz)
Copyright in Germany is governed by the UrhG, which is based on the author-centred (droit d’auteur) tradition. The author is the natural person who created the work (§ 7 UrhG). Protected works under § 2 include literary works, musical works, pantomime and dance works, artistic works, photographic works, cinematographic works, and representations of a scientific or technical nature.
Moral Rights
German copyright law grants robust moral rights (Urheberpersönlichkeitsrechte) under §§ 12-14 UrhG: the right of publication (Veröffentlichungsrecht), the right of attribution (Recht auf Anerkennung der Urheberschaft), and the right to prohibit distortion or derogatory treatment of the work (Entstellungsverbot). These rights are inalienable and persist after the transfer of economic rights.
Economic Rights
The economic rights under §§ 15-24 UrhG include the right of reproduction (Vervielfältigungsrecht), distribution (Verbreitungsrecht), exhibition (Ausstellungsrecht), and communication to the public (Recht der öffentlichen Wiedergabe), which encompasses broadcasting, public performance, and making available on demand.
Copyright Contract Law
German copyright contract law (Urhebervertragsrecht) under §§ 31-44 UrhG provides statutory protections for authors in their contractual relationships, including the principle of purpose transfer (Zweckübertragungsgrundsatz), under which the scope of a granted licence is determined by the purpose of the contract.
Exceptions and Limitations
The exceptions include private copying (§ 53 UrhG) subject to fair compensation via statutory levies on recording equipment and blank media, quotations (§ 51 UrhG) for scientific, critical, and educational purposes, and use for teaching, research, and public safety.
Ancillary Copyright for Press Publishers
The Leistungsschutzrecht für Presseverleger, introduced in 2013, grants press publishers an ancillary copyright in press publications for one year, allowing them to assert rights against commercial news aggregators and search engines.
Term
The general term is life of the author plus 70 years (§ 64 UrhG). For anonymous and pseudonymous works, the term is 70 years from publication.
Trade Mark Law
The Trade Mark Act (Markengesetz)
The MarkenG governs trade marks, business identifiers, and geographical indications. Protection may be obtained through registration with the DPMA, through use in commerce (acquired distinctiveness), or by virtue of being a well-known mark under Article 6bis of the Paris Convention.
Registration and Distinctiveness
Registration requires the mark to be a sign capable of distinguishing the goods or services of one undertaking. Absolute grounds for refusal under § 8 MarkenG include lack of distinctive character, descriptiveness, and customary indications. Relative grounds under § 9 include conflicts with earlier marks.
Infringement and Well-Known Marks
Infringement under § 14 MarkenG arises from identical or similar marks used for identical or similar goods or services where likelihood of confusion exists. Marks with a reputation are protected against detriment or unfair advantage even for dissimilar goods. The protection of well-known marks (notorisch bekannte Marken) under § 10 MarkenG transposes Article 6bis Paris Convention.
Design Rights and Unfair Competition
Registered designs under the Designgesetz protect the appearance of products, requiring novelty and individual character, with a term of up to 25 years. The Act Against Unfair Competition (UWG) provides supplementary protection against misleading commercial practices, comparative advertising, and the misappropriation of trade secrets under § 17 UWG (criminal liability) and the Trade Secrets Act 2019 implementing Directive 2016/943.
