Trademarks

Comprehensive trademark practice includes right-to-use and clearance searches, preparation, direct filing and prosecution of US (use-based, intent-to-use, based on foreign registrations), European, Swiss, Liechtenstein and International trademark applications and through our association with a carefully selected group of associates in all countries of the world, as well as cancellation and opposition proceedings at the trademark office, appeals and trademark infringement litigation.

We also handle paying renewal fees once your trademarks are registered, and in particular also filing the Declaration of Use with the US trademark office.
