Collective marks differ from conventional trademarks—which typically belong to an individual or a company—in that they are owned by a legal association (§ 97 of the Trademark Act), which may include umbrella or leading associations. A collective mark may also include a geographical indication and can only be registered in conjunction with a trademark statute that meets specific requirements. It must be clearly distinguishable from the goods or services of other companies by its geographical or operational origin, type, or quality (for example, as seen in certain quality seals or products such as champagne or Thüringer Rostbratwurst).
