Patent Bots recently announced its fourth annual Patent Quality Rankings of top patent law firms. Last month, we unveiled the
Top 50 Patent Firms.
Today, we'll announce the Top 10 firms in each USPTO Tech Center.
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 patent firms in each Tech Center 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.
Nearly 290,000 (90%) of patents contained at least one detectable error. That's why Patent Bots created the world's fastest and most accurate patent drafting and proofreading solution.

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.
Learn more about our methodology.
