Jeffrey M. Fisher has a diverse practice involving a variety of high stakes intellectual property and technology disputes, including patent, trade secret, copyright and trademark infringement, as well as antitrust and unfair competition cases. He serves as chair of Farella’s Intellectual Property Litigation Department.

Mr. Fisher has been active in all phases of litigation, in both federal and state courts and at both the trial and appellate levels. He has specific experience with semiconductor and chip packaging technologies; computer hardware, software and networking technologies; DNA, life sciences, medical devices and biopharmaceutical technologies; solar technology; internet and encryption technologies; digital data compression technology; and data centers. He also represents clients in connection with parallel Patent Trial and Appeal Board (PTAB) proceedings.


Notable engagements include:

  • Winning a jury verdict following a five week trial on trade secret and breach of NDA claims including a finding of willful and malicious misappropriation in a case pending in the Northern District of California relating to data center technology.
  • Winning a jury verdict following a three week jury trial for our client Volterra Semiconductor Corporation in the Northern District of California upholding the validity of Volterra's key patents for flip chip integrated power switches against challenges by defendants Infineon and Primarion. Infringement in favor of our client had been determined prior to trial as a result of key rulings we obtained in favor of Volterra in connection with claims construction and summary judgment proceedings.

  • Representing Dolby Laboratories in seeking a declaratory judgment that Dolby’s AC-3 (“Dolby Digital”) technology did not infringe patents that Alcatel-Lucent had asserted against Dolby’s licensees. Following protracted litigation, in which we obtained discovery sanctions against Alcatel-Lucent on multiple occasions and attorneys’ fees at the conclusion of the case, we successfully obtained orders granting summary judgment of non-infringement on the patents-in-suit. The Federal Circuit affirmed the district court's orders awarding summary judgment and attorney's fees.
