Trademark registration

ab&d Rechtsanwälte protect marks in Germany, Europe and beyond. We check the eligibility of a desired mark for protection under the Trademarks Act and the Community Trademark Regulation (GMVO), particularly for the necessary distinguishing force and a potential need to keep the use of the mark free. We carry out trademark searches to establish whether there are older third-party rights to the desired mark. Finally, we support the entire registration and entry procedure and represent the interests of the applicant and mark proprietor in any potential opposition, appeal or objection proceedings before trademark offices and the responsible courts (e.g. the Patent Court).

Once a mark has been registered successfully, we can advise you on the necessary protective measures, which include, for example the assertion of your mark rights in the event of infringement by a third party (e.g. by issuing a warning or applying for an injunction), in court and out of court.
