Trademark law
In the narrower sense, trademark law refers to the law governing trademarks as signs or designations identifying goods or services. In a broader sense, it includes all signs regulated by the German Trademark Act (Markengesetz), including, for example, company names and work titles.
What is a trademark?
Trademark as a legally protected sign with a right of interdiction
A trademark is a legally protected sign (designation, logo, possibly also a color). It serves to distinguish the goods or services of one company from the goods or services of another company. A trademark is intended to indicate that the goods or services originate from a particular company (origin function). In contrast to a company mark, which identifies a company or part of a company (e.g. "Amazon"), a trademark always identifies a product (goods or services). A trademark gives its owner the right to use the protected or a similar sign for identical or similar products.
However, a logo or designation must also be "used as a trademark" for this use to be a trademark infringement in the first place.
Types of trademarks
Trademarks can be distinguished, for example, according to their geographical area of protection, e.g. as a
- Registered German trademark
- German utility mark
- EU trade mark (the "European trademark"; formerly: Community trademark)
- IR trademark, internationally registered trademark
Regardless of the geographical scope, a
- position mark
a sign claiming protection for a specific position on a product. A
- cerification mark, also known as a EU certification mark, in turn, guarantees certain characteristics of a good or service wether a
- collective mark or a EU collective mark indicates that the goods or services protected by that mark originate from members of an association, and may only be used by them.
Trade mark filing and protection
Trade mark protection in Germany is obtained by registering a sign in the trade mark register of the German Patent and Trade Mark Office (DPMA). More or less uniform trade mark protection in the 27 member states of Europe is obtained by registering an EU trade mark with the European Union Intellectual Property Office - EUIPO.
The international registration of a German trade mark or an EU trade mark at WIPO gives the trade mark the same protection in the member states of the Madrid Agreement as a trade mark of the respective member state. Currently, 84 states and confederations of states are contracting parties to the Madrid system, including the European Union.
However, a German trade mark can also come into existence through use alone, cf. section 4 no. 2 German Trademark Act (MarkenG). The prerequisite for this is that the sign in question has acquired "reputation". In practice, these cases are very rare.
Registration is preceded by filing a trade mark application. A trade mark search is indispensable before filing the application. This is because the filing of an application for a trade mark that conflicts with an earlier trade mark already gives rise to the risk of first infringement of a trade mark right.
What can be protected as a trademark?
In principle, words, names, pictures, letter combinations, numbers, acoustic sound sequences, three-dimensional shapes, product packaging, color combinations, tactile marks, and theoretically also smells can be protected as trademarks. Trademarks, however, must be able to be represented graphically. This has not yet been achieved in the case of the latter. In any case, the filing of a chemical formula is not sufficient. Descriptive indications or other absolute grounds for refusal are not registrable as trademarks. Furthermore, the trademark may not be deceptive about characteristics of the goods/services, contrary to public order or contain official coats of arms or seals. The use of official coats of arms, flags, seals, test marks is also an administrative offense.
Origin of trademark protection
Trademark protection in Germany is obtained by registering a sign in the trademark register of the German Patent and Trademark Office. A more or less uniform trademark protection in the 27 member states of Europe arises through registration of an EU trademark at the European Union Intellectual Property Office - EUIPO (formerly: Office for Harmonization in the Internal Market - OHIM/OAMI).
By registering a German trademark with WIPO, the German trademark receives the same protection in the member states of the Madrid Agreement as a trademark of the respective member state. Currently, 84 states and confederations of states are parties to the Madrid system, including the European Union.
However, a German trademark can also come into existence through use alone, see Sec. 4 No. 2 German Trademark Act (MarkenG). The prerequisite for this is that the sign in question has acquired "reputation". The cases are practically very rare.
Requirements for the protection of a trademark
The most important requirement for protection of a trademark is distinctiveness. Descriptive indications, on the other hand, cannot be registered as a trademark. In addition, the trademark may not be deceptive as to the characteristics of the goods/services, be contrary to public policy or contain official coats of arms or seals. The use of official coats of arms, flags, seals, test marks is also an administrative offense and thus punishable by law. Official test marks generally bear a coat of arms, for example the German federal eagle.
