Expert Witness Services

Given the depth of our experience, and the breadth of our practice, it’s not surprising that Pattishall lawyers are regularly tapped as expert witnesses in IP matters.

We have broad experience testifying in litigation on:

  • Copyright, trademark and unfair competition matters
  • False advertising
  • IRS and corporate evaluations of brand assets
  • Trade dress and product design
  • Licensing and contracts
  • Malpractice and ethics
  • U.S. Patent and Trademark Office practice and procedures.

A Pattishall attorney served as an expert for the Internal Revenue Service in Nestle Holdings v. The Commissioner of Internal Revenue, a dispute over Nestle’s low valuation of brand assets when it acquired Carnation Company. By showing that Carnation’s maintenance records tracked the strengths and weaknesses of the transferred brands, expert testimony demonstrated that Nestle’s evaluation was incorrect, winning a favorable settlement for the Internal Revenue Service.

For General Motors, our three-pronged analysis protected the shape of GM’s Hummer vehicle as distinctive, non-functional and infringed by Avanti Motor Corporation.

Please contact us about serving as experts, either for testimony or assistance analyzing your case.
