2023 Patent Quality Rankings: The Top 50 Patent Law Firms

Somerville, MA: Patent Bots, the creator of AI-enabled software-as-a-service applications for patent attorneys, is pleased to announce its fourth 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 746 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.

• 323,393 patents processed by the Patent Bots AI
• 33,425 (10.3%) patents achieved a perfect Patent Quality Score
• 9 average errors per patent
• 5 median errors per patent

Patent Bots detected at least one numbering, antecedent basis, or word support error in nearly 90 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.”

Harrity & Harrity / Qualcomm placed first among firms with 50+ patents issued.
