Patent Bots proofread an entire year of issued patents to determine the top patent firms.
Somerville, MA: Patent Bots, creator of AI-enabled software for patent attorneys, is pleased to announce its sixth 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 710 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.
- 314,170 patents processed by the Patent Bots AI
- 38,531 (12.3%) patents with a perfect Patent Quality Score – up from 11.4% in 2024
- 55 average errors per patent – down from 6.75 in 2024
- 4 median errors per patent
The decline in errors per patent is not a one-year phenomenon. The average has declined by over 25% in just six years – from 8.9 errors per patent in 2020 to an all-time low of 6.55 this year. The decrease coincides with the rise of automated patent proofreading tools like Patent Bots Prep & Pros Pro.
“I started Patent Bots because I saw the enormous value of automated proofreading in my own patent practice,” Patent Bots founder and patent attorney Jeff O’Neill said. “The data is clear: Practitioners who use automated proofreading achieve a significant drop in their error rates.”
Despite the decline, Patent Bots detected at least one numbering, antecedent basis, or word support error in nearly 88% 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,” O’Neill said. “Modern AI-enabled automated proofreading solutions like Patent Bots make it easy to diagnose and fix errors and get better outcomes for clients.”
2025 Patent Quality Rankings: Top 10 Patent Law Firms.
GTC Law Group jumped from No. 11 in our 2024 rankings to place first among firms with 50+ patents issued. (GTC Law Group is a Patent Bots customer, and O’Neill was formerly a patent attorney for them.)
“We require our people to use Patent Bots. It is not an optional tool,” GTC Law Group principal and patent strategy specialist John Monocello said. “Quality is not just a philosophy. It’s a methodology. By requiring technology use at critical points in the process, we’ve been able to ensure high quality and accuracy.”
Note: Some companies file their own patents rather than filing through outside counsel. In these instances, the company is both the patent filer AND the patent owner and is included in our rankings as both a firm and a company. The company rankings will be released later this year.
