2023 Patent Quality Rankings: The Top 50 Patent Law Firms

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

We used our advanced machine learning software to review every patent issued  over 320,000!  by the USPTO in the past year. We then ranked the 746 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.
  • 323,393 patents processed by the Patent Bots AI
  • 33,425 (10.3%) patents achieved a perfect Patent Quality Score
  • 7.9 average errors per patent
  • 5 median errors per patent
Nearly 290,000 (90%) of all patents issued in the last year contained at least one numbering, antecedent basis, or word support error. There is clearly room for improved accuracy in the industry. 

That is why Patent Bots created the world's fastest and most accurate patent drafting and proofreading solution. Try Patent Bots FREE for 14 days.

2023 Patent Quality Rankings: Top 50 Firms Overall. 

Large firms don't have a monopoly on patent accuracy. Smaller firms with between 50 and 500 patents granted are doing excellent work as well. 

A quick note about the rankings: Some companies file their own patents rather than filing through outside counsel. In these instances, the company is both the patent filer AND the patent owner and is included in our rankings as both a firm and a company. The company rankings will be released later this year.

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.
