At Patent Bots, we used our advanced machine learning software to proofread an entire year of issued patents and then ranked 700 companies by the smallest average number of errors in the issued patents.

Here, we announce the top 10 US companies for patent quality with at least 250 issued patents in the last year.  

Congratulations to these companies for doing amazing work!

For greater accuracy, Patent Bots Quality Scores are computed using only a few of the types of errors in our proofreading results: numbering errors, antecedent basis errors, and word support errors (words that don't appear in the detailed description).

Although we may over or undercount 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 company's work. See here for more details about our methodology.
