William McCabe is a patent litigator with over three decades of experience handling patent infringement and trade secret actions, licensing and re-examinations. Bill has represented sophisticated U.S., European and Asian companies in high-stakes patent litigation and counseling matters, from New York to Tokyo and Seoul, including one patent trial widely viewed as the biggest “defense” win in U.S. patent litigation history. Bill obtained a judgment of noninfringement, invalidity and unenforceability against a defendant that had already collected more than $1.5 billion from over 1,000 companies.

Bill’s experience spans a variety of industries, including telecommunications, digital cameras, optics, semiconductors, software, medical records, energy, polymers, interferon, chemical engineering and electrochromics. In the high-tech arena, he has handled significant, high-stakes litigation involving CDMA and Wi-Fi technologies, encrypted VoIP and optical switches used in wavelength-division multiplexing (WDM) for telecommunications networks.

Additional industry areas of his patent litigation experience include automotive mirror products, bar code and machine vision technology and arcade games. Bill earned his undergraduate degree in chemical engineering and began his career as a refinery startup engineer for UOP.
