About

Provided by Morrison Foerster

Morrison & Foerster is an IP powerhouse, representing clients in their complex patent, copyright, trademark, trade dress, trade secret, and IP transaction matters. Clients come to us for our ability to combine market-changing IP experience with scientific and technical expertise on a global scale.

We are adept at resolving disputes short of trial, but when cases do see the inside of a courtroom, the prowess of our litigators is second to none. The size and experience of our litigation team have provided us with expertise in a variety of venues, including all of the district courts that handle high volumes of patent litigation, the U.S. International Trade Commission, and the U.S. Court of Appeals for the Federal Circuit.

Our global patent prosecution group is the largest of any general practice firm, with 65 Ph.D. in technology and life sciences. We are particularly skilled in the strategic planning of patent portfolios, including—for example—writing successful patent applications in complex and novel situations, in anticipation of possible future litigation. We work closely with clients from the earliest stages of their technical development, offering valuable advice about how to protect their inventions and new ideas in view of their business strategies.
