2022 Patent Bots Quality Rankings: The Top 50 Patent Law Firms

Patent Bots is pleased to announce its third annual Patent Quality Rankings of top patent law firms. 

We used our advanced machine learning software to review every patent issued – over 300,000! – by the USPTO in the past year. We then ranked the 736 most active patent law firms 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. 

Patent Accuracy: By the Numbers.

Before we unveil the top 50 patent law firms, let's take a look at the state of patent accuracy.

• 322,000 patents processed by the Patent Bots AI
• 16,434 patents achieved a perfect Patent Bots Quality Score
• 11.2 average errors per patent
• 7 median errors per patent

More than 305,000 patents issued in 2021 contained at least one numbering, antecedent basis, or word support error. There is clearly room for improved accuracy in the industry.

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 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.
