we protect your IP worldwide

We have access to the right specialists for all of your IP needs!


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.


We handle your designs from the preparation of the application, the filing, the prosecution, through grant. We will work together on a strategy for your design applications that best suits your needs and plans for the future.


There are essentially only two copyright offices in the world. One in the US, and the other one in China. We have extensive experience in copyright practice before the U.S. copyright office especially with respect to jewelry and computer software including prosecution and infringement litigation.

IP Agreements

Because IP rights may, among others, be licensed, assigned, acquired, or given away, it is important that the related contracts are negotiated and entered into in due time.
