2025 Patent Quality Rankings: Top 10 Firms in Each USPTO Tech Center

Patent Bots recently announced its latest Patent Quality Rankings of top patent law firms. In April, we unveiled the Top 50 Patent Firms. 

Today, we're excited to share the Top 10 firms in each USPTO Tech Center. 

As we've done every year since 2020, we used our advanced machine learning software to review every patent issued – more than 314,00 this year! – by the USPTO in the past year. 

We then ranked patent firms in each Tech Center based on the average number of numbering, antecedent basis, and word support errors detected in their patents. Our rankings are based only on the above errors and do not address many other important aspects of patent quality.

More than 275,000 (88%) of patents issued contained at least one detectable error. If your firm doesn't use automated proofreading, try Patent Bots FREE for 14 days.

Now, on to the rankings!

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 the 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.
