Johannes Großekettler advises our clients on the national and international enforcement and defense of their valuable trademarks and other intellectual property rights.

This includes support and representation in complex cross-border conflicts including trademark litigation and proceedings before trade mark offices (e.g. opposition, revocation and invalidity proceedings). Plus quick and cost-effective resolutions out of court.

Johannes is particularly well experienced with single letter trademarks, other unconventional trademark types and with coordinating the company and group-wide collection of proof of use in order to defend trademarks in extensive revocation proceedings. 

In his practice, Johannes works closely with a world leading telecommunications and IT corporation protecting its brand, which according to Brand Finance ranks amongst the most valuable brands worldwide.

As tech-savy lawyer and innovative "product owner", Johannes pushes forward innovation and the development of a new Hogan Lovells cloud solution for the management of proof of use.

Representative experience

Regular support of one of the world's leading telecommunications and technology companies regarding the enforcement of its core brands.
Supporting a well-known car manufacturer in trade mark appeal proceedings regarding a car model that was already available on the market and in resolving the matter amicably.
