2025 Patent Quality Rankings: The Top 50 Patent Law Firms

Patent Bots is excited to announce our sixth annual Patent Quality Rankings of top patent law firms!

As we've done every year since 2020, we used our advanced machine learning software to review every patent issued – more than 314,000 this year! – by the USPTO in the past year. 

We 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. Our rankings are based only on these error types and do not address many other important aspects of patent quality. 

The State of Patent Accuracy in 2025.

Before we unveil the top 50 patent law firms, let's take a look at the state of patent accuracy.

• 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
• 6.55 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. In fact, 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 in errors coincides with the rise of automated patent proofreading tools like Prep & Pros Pro by Patent Bots. As more patent attorneys have implemented these tools into their workflows, the prevalence of errors has decreased steadily – and dramatically – year after year. 

That said, more than 275,000 (88%) of all patents issued in the last year contained at least one numbering, antecedent basis, or word support error. If your firm doesn't use automated proofreading, try Patent Bots FREE for 14 days.

Now, on to the rankings!

2025 Patent Quality Rankings: Top 50 Patent Law Firms. 

Congratulations to Patent Bots customer GTC Law Group for jumping from No. 11 in our 2024 rankings to place first among firms with 50+ patents issued. (Our founder Jeff O’Neill was formerly a patent attorney for GTC Law Group.)

“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.

Patent Quality Rankings Methodology. 

The Patent Quality Rankings are based only on average errors in issued patents and don't address other important aspects of patent quality. 

For purpose of computing quality scores, we used only numbering errors, antecedent basis errors, and word support errors (words that don't appear in the detailed description).

Although we may over- or under-count errors in an individual patent, the average number of errors across all of a firm's patents is a good indicator of the overall quality of the firm's work.
