Opinions of counsel play a significant role in informing and guiding management. Offensively, they are important in determining whether a third party may be infringing the claims of a patent. Defensively, opinions can be used to determine whether a company, if accused of infringing a third party's intellectual property rights, can continue business activities without being accused of willful infringement.

Opinions must be competent and reasonable to withstand the scrutiny of a court and provide the foundation on which clients can rely in decision-making. Our opinions are based on several factors:

  • A review of newly-issued court opinions ensuring advice is based on the most pertinent case law
  • A keen understanding of the broad range of intellectual property issues stemming from decades of experience prosecuting patents and trademarks before the U.S. Patent and Trademark Office
  • A thorough analysis of a patent file history in order to assess the scope of a patent
  • Technical training that reveals nuances that can make an important difference in the outcome of a case
