2026 Patent Quality Rankings: The Top 50 Patent Law Firms

Somerville, Mass. – Patent Bots, creator of AI-enabled software for patent attorneys, is pleased to announce its seventh annual Patent Quality Rankings of top patent law firms.

Patent Bots used its advanced machine learning software to review every patent issued by the USPTO in the past year. It then ranked the 709 patent law firms with 50+ patents issued based on the average number of numbering, antecedent basis, and word support errors detected in their patents. Rankings are based only on these errors and do not address many other important aspects of patent quality.

• 327,684 patents processed by the Patent Bots AI
• 46,013 (14%) patents with a perfect Patent Quality Score – up from 12% in 2025
• 38 average errors per patent – down from 6.55 in 2025
• 4 median errors per patent

The average number of errors per patent has declined from 8.9 errors when Patent Bots began the rankings in 2020 to an all-time low of 6.38 this year. The decrease coincides with the growth of automated patent proofreading tools like Patent Bots Prep & Pros Pro.

“Over the years, the Patent Bots solutions have grown to include AI-powered drafting, art unit prediction, a tool for patent families and histories, document preparation automation, and more. But proofreading was the original solution, and the reason I built Patent Bots. When I founded the company, it was based on this simple realization: automated proofreading was making me a better patent attorney,” said Jeff O’Neill, Patent Bots founder and CEO. “And the numbers back it up; practitioners who use this kind of tool see a meaningful reduction in errors across their work.”

Despite the reduction, Patent Bots detected at least one numbering, antecedent basis, or word support error in 86% percent of patents issued last year.

“Patent errors don’t just create administrative headaches; they drive up costs and can jeopardize a patent’s validity down the line,” said O’Neill. “AI-powered proofreading solutions like Patent Bots give practitioners a smarter, faster way to catch and correct those errors, ultimately delivering stronger results for their clients.”
