He is ranked among the top 3% of best-performing practitioners – out of over 5,000 attorneys – when representing petitioners in Patexia’s IPR Intelligence Report.


Jason Balich is a trial and appellate lawyer who protects his clients’ technologies and defends their freedom to use them. Jason is also an engineer, an inventor, and a business owner. He has successfully defended multiple patent owners—from manufacturers to public universities—facing inter partes review challenges at the Patent Trial and Appeal Board (PTAB), where the institution was denied. Jason regularly represents manufacturers as both plaintiffs and defendants in patent, trade secret, and commercial litigation before district courts and at the International Trade Commission (ITC). Jason authors the quarterly “Patent Update” column in Chemical Engineering Progress, the flagship publication of the American Institute of Chemical Engineers. Jason has been repeatedly named to the list of Massachusetts Rising Stars by Super Lawyers and has been recognized on the Best Lawyers: One to Watch list by The Best Lawyers in America©.

Tom’s background includes working in systems and software engineering. In addition, he was involved in designing a satellite that NASA ultimately selected for launch.

Stuart V.C. Duncan Smith is an experienced civil litigator focusing his practice on contested matters involving intellectual property. He has significant experience in federal and state courts across the country, the US International Trade Commission (ITC), and the US Patent and Trademark Office (USPTO).

His litigation and post-grant experience encompasses a wide array of subject matters, including antibody drug discovery, internet communications, pharmaceuticals, and consumer electronics. Stuart is also active with the firm’s pro bono clients, he serves on the firm’s Public Services Committee, which oversees the firm’s pro bono program, and he leads the firm’s efforts to raise funding for civil legal aid organizations.
