Experience

  • Represent private equity-owned Wayne Fueling Systems, formerly a division of General Electric, which manufactures fuel dispensers for petroleum retailers and commercial fleets, and compressed natural gas fueling pumps. Mintz handles worldwide patent and trademark strategy and prosecution, and enforces those protections in the US and abroad. The firm's relationship attorney serves as outside patent counsel and sits on the patent review committee, working directly with the company's stakeholders in developing patent strategy.
  • Advised medical device client on developing and implementing a post-litigation strategy. Having lost a patent litigation (in which they were represented by another law firm), Mintz attorneys helped the company assess whether they could keep their product on the market during the appeal process. We then provided advice on how to create possible design-arounds for the product to ensure it was clear of infringing the patents at issue, in the event that the appeal was unsuccessful.
  • Developed an IP strategy for a start-up company that designed a cap for user in monitoring compliance for inhalers to treat asthma. Built a successful portfolio based on the strategy, which led to a successful exit.
