At Patent Bots, we proofread an entire year of issued patents and then ranked 676 companies by the smallest average number of errors in the issued patents.
Congratulations to these companies for doing amazing work! To improve your company's patent quality scores, use Patent Bots automated proofreading to remove errors in your work.
See our PatentVerse page to see how your company does in comparison. Other than the top 50 companies, you can only see your own company's ranking (we don't want to publicly identify companies 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.
