At Patent Bots, we used our advanced machine learning software to proofread an entire year of issued patents. We then ranked 787 US law firms by the smallest average number of errors in the issued patents.
Here, we announce the top 10 US law firms for patent quality with at least 500 issued patents in the last year. Congratulations to these firms for doing amazing work!
Next week, we will be announcing the overall top 50 US law firms to be followed by the top firms in different tech centers and the top companies.

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 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. See here for more details.
Note that these rankings are based only on average errors identified by our software in issued patents and don't address other important aspects of patent quality.
