Partner, Litigation Department


Matthias Kamber is a partner in the Intellectual Property practice of Paul Hastings and is based in the firm's San Francisco office. Mr. Kamber focuses on litigating intellectual property cases and has tried approximately ten jury and bench trials.

In particular, Mr. Kamber has handled patent cases involving internet advertising and telephones, smartphones, and microprocessors throughout the country and before the U.S. International Trade Commission.
