Representative Matters

A selection of Mr. Masson's representative matters includes:

  • Successfully drafted and prosecuted patents for a user interface for restaurant equipment for a Fortune 150 company in the United States, Australia, Canada and Japan.
  • Obtained a finding of breach of patent license and patent validity relating to optics in an International Chamber of Commerce arbitration between an American licensor and a French defense contractor. A decision on damages is pending.
  • Discovered massive spoliation of evidence in trade secrets litigation relating to fine chemicals, which ultimately led to defendant pleading guilty to four criminal counts of unauthorized possession of stolen trade secrets, a permanent injunction and a multimillion dollar judgment.
  • Successfully defended a small store against a trademark owner's assertions of trademark infringement in two cease-and-desist letters.
  • Successfully prosecuted patents for a natural food product for a Fortune 100 company. Highlights included defeating a post-grant opposition proceeding before the European Patent Office and overcoming a rejection by the Venezuelan patent office by writing arguments partially in Spanish referencing the specific wording of substantive Venezuelan patent law.

  • Successfully prosecuted patents in the U.S. Patent and Trademark Office and the European Patent Office (EPO) for a solo inventor obtaining broad coverage in the material sciences. In the EPO, successfully overcame a unity of invention rejection allowing broad coverage to be achieved in a single patent.
