Overview

John Purcell is a Partner and registered patent attorney at Gray Ice Higdon focusing his practice on patent prosecution for software-related inventions and the strategic growth and management of patent portfolios. He represents a wide range of clients — from individual inventors and early-stage startups to large global technology companies — helping them identify white space for patent protection in their industries and gaps in existing patent portfolios to ensure they are well positioned for next 20 to 30 years of technological change.

What makes John exceptional is his ability to quickly absorb complex, cutting-edge technology and translate it into patent protection that is both accurate and strategically tailored. Whether the invention involves generative AI, autonomous vehicles, robotics, or whatever comes next, John engages with it at a technical level most attorneys simply cannot. He earned a B.S. and M.Eng. in Electrical and Computer Engineering — both with High Honors — before earning his J.D. cum laude. His clients don't just get a lawyer. They get a strategic partner who understands the technology, the competition, and what truly great patent protection looks like.

Practice Focus

John's practice is built around two interconnected goals: protecting what clients have built today, and positioning their portfolios for what comes next.

  • Patent drafting and prosecution for software inventions, AI, autonomous vehicles, robotics, and other emerging technologies
  • Strategic prosecution that molds protection around how the technology — and the competitive landscape — will evolve
  • Patent portfolio review, management, and strategic growth — identifying white space for patent protection and steering prosecution to cover client and competitor products alike
  • Clear, accessible communication with clients of all experience levels, from first-time inventors to sophisticated patent teams
