Los Angeles

Lewis Roca Rothgerber Christie is one of the leading intellectual property law firms in southern California. All of our lawyers have a broad variety of scientific backgrounds, with an undergraduate degree in science or engineering, and several have graduate degrees.

Our patent attorneys have a national reputation for high caliber performance at the U.S. Patent Office and other venues, and our litigators can make even the most complex technical subjects clear to judges and juries alike. For us, it's the best possible world—we're lawyers, but we get to work with science and technology every day.

Reflecting our role as a legal community leader, Lewis Roca Rothgerber Christie actively encourages its lawyers and staff to act as a community service leader, with active involvement in many area nonprofits, community groups and educational institutions.
