Our Global Reach

United States
Our professionals bring in-depth experience and leadership in all aspects of IP law. We represent U.S. organizations as well as multinational companies that wish to conduct business in the U.S. We have established offices in some of the largest technology centers in the United States, including Houston, Austin, Boulder and Washington, D.C. Our U.S. practice includes all aspects of intellectual property law.


Representing European and non-European companies of all sizes before the EPO and the French Patent Office, our Paris office is tightly integrated with the practices of the firm’s other offices so as to ensure an efficient, coordinated global approach. Our Paris office legal staff includes qualified European and French patent attorneys, thus allowing us to communicate directly with clients about European and French patent law in the three official languages of the EPO. Our European practice is comprehensive, with a particular focus on European opposition and limitation proceedings, European and French litigation support and strategy, European and French national patent prosecution, patent drafting, prior art searches and patent watch services, IP due diligence, patent education seminars and counseling to assist in the implementation of in-house IP strategies.


With fluency in Japanese language and deep knowledge of local customs, we can easily move between the Western and Japanese ways of doing business and help our clients avoid the subtle pitfalls that make cross-cultural ventures difficult. With bilingual, licensed patent attorneys on the ground in both Japan and the U.S., we are able to effectively and efficiently serve local Japanese and overseas companies. Our Japanese practice includes litigation support and strategy, client liaison for Japanese companies and law/patent firms, IP licensing, opinion work and IP consulting on U.S. and European patents.

In view of the ever-changing landscape of IP rules and regulations in China, our Hangzhou office plays a vital role in providing real-world advice on IP issues and executing agreed-upon strategies while also providing quality work in an efficient and effective manner. Whether it be a Chinese company wishing to access the international market, or a non-Chinese company wishing to do business in China, our local expertise and tight integration with our U.S., European, and Japanese practices allows us to effectively address any IP matter.
