Patent Bots proofread an entire year of issued patents to determine the top 10 large patent firms and the top 50 overall.

Somerville, Mass. – Patent Bots, creator of the world’s fastest and most accurate automated patent drafting and proofreading solution, is pleased to announce its third 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 736 most active patent law firms 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.

  • 322,000 patents processed by the Patent Bots AI
  • 16,434 patents achieved a perfect Patent Bots Quality Score
  • 11.2 average errors per patent
  • 7 median errors per patent

Patent Bots detected at least one numbering, antecedent basis, or word support error in nearly 95 percent of patents issued last year.

“Errors in patents can increase the costs of obtaining a patent and lead to validity issues in the future,” Patent Bots founder and practicing patent attorney
Jeff O’Neill said. “Modern AI-enabled automated proofreading solutions like Patent Bots make it easy to fix errors and get better outcomes for clients.”
