At Patent Bots, we proofread an entire year of issued patents and then ranked 802 law firms by the smallest average number of errors in the issued patents.
Congratulations to these firms for doing amazing work! To improve your firm's patent quality scores, use Patent Bots automated proofreading to remove errors in your work.
See our PatentVerse page to see how your firm does in comparison. Other than the top 50 firms, you can only see your own firm's ranking (we don't want to publicly identify firms doing lower quality work). Note that these rankings are based only on average errors in issued patents and don't address other important aspects of patent quality.
We rank the top 50 firms overall and also the top 10 in each tech center:
