Jeffrey K. Sherwood


Jeff Sherwood tries patent infringement and trade secrets cases. Recognizing the innate complexity of these cases, he challenges both his trial witnesses and his team to bring the cases to life for jurors. Jeff is not technically trained, which makes that challenge important for his own understanding of the key issues. He learns a case’s technology environment like a juror and then simplifies the client’s presentation with:

  • visual learning by USA Today style graphics or models (e.g., a custom water tank to simulate operation of a semiconductor circuit)
  • metaphors or analogies to common juror experiences (e.g., comparison of DRAM addressing to dialing a telephone number)
  • thematic presentations informed by jury research on framing key issues for jurors
  • translating case issues into common life experiences

“Sherwood is a trial lawyer with ‘an extraordinary ability to turn something complicated into something simple. He’s so smart and can separate the wheat from the chaff; he also presents to the court in a very effective fashion because he uses language that people can understand.’”—IAM Patent 1000 (2016)

Jeff practices throughout the United States. In the role of lead trial counsel, he has tried cases to verdict in several active patent courts, including Delaware, Virginia, New Jersey, and Texas. The National Law Journal twice recognized his defense verdicts and once recognized his patent plaintiff’s verdict in its annual reviews of top verdicts in the United States. He has handled Markman hearings in additional courts, including California, Illinois, and Pennsylvania.

Jeff's past cases encompass a wide variety of technologies:

  • semiconductor architecture and fabrication
  • nuclear power systems
  • telecommunications
  • chemical manufacturing and application
  • pharmaceutical products
  • textile processing
  • search engine and other Internet technologies
  • computer software and hardware
  • utility power conservation systems

Jeff is a past practice group leader of Blank Rome’s intellectual property and technology group and served a similar function in his prior firms.
