Patent Prosecution

  • Established client patent program, including educating potential inventors on patent law and on completing invention disclosure forms for patentability searching and patent filings.
  • Successfully prosecuted patents for a natural food product for a Fortune 100 company. Highlights included defeating a post-grant opposition proceeding before the EPO and overcoming 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 United States and the European Patent Office (EPO) for a solo inventor, obtaining broad coverage in the material sciences. The EPO successfully overcame a unity of invention rejection, allowing broad coverage to be achieved in a single patent.
  • Successfully drafted and prosecuted patents for a user interface for restaurant equipment for a Fortune 150 company in the United States, Australia, Canada, China, and Japan.

Dispute Resolution

  • Successfully had two patent trolls dismiss their software patent lawsuits without any settlement. In the first lawsuit, effectively filed a motion to dismiss based on the asserted patent being abstract. In the second lawsuit, successfully threatened to file a motion to dismiss based on the asserted patent being abstract and a lack of factual allegations of infringement.
  • Negotiated a favorable settlement prior to filing an answer, as statutory damages were unavailable to the photographer plaintiff because the client's use of a photo began after the photo was published and before the effective date of the copyright registration.
  • As second chair, achieved a multimillion-dollar award for breach of a patent license relating to optics in a complex International Chamber of Commerce arbitration seated in London between an American licensor client and a French defense contractor.
  • Discovered massive spoliation of evidence in trade secrets civil litigation relating to fine chemicals. This discovery culminated in the defendant pleading guilty to four criminal counts of unauthorized possession of stolen trade secrets and agreeing to a permanent injunction and a multimillion-dollar judgment for our client.
  • Successfully defended a home brew store against a trademark owner's infringement assertions in two cease-and-desist letters.


  • Performed environmental due diligence for the purchase of an American chemical company by a European purchaser and provided guidance to the purchaser for obtaining approval from the Committee on Foreign Investment in the United States and the Directorate of Defense Trade Controls.
