2024 Patent Quality Rankings: The Top 50 Patent Law Firms

It's been five years since we first sought to quantify the state of patent accuracy in the U.S. Today, Patent Bots is pleased to announce our FIFTH annual Patent Quality Rankings of top patent law firms!

As we've done every year since 2020, we used our advanced machine learning software to review every patent issued – nearly 324,000 this year! – by the USPTO in the past year. 

We then ranked the 730 patent law firms with 50+ patents issued based on the average number of numbering, antecedent basis, and word support errors detected in their patents. Our rankings are based only on these error types 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.

• 323,820 patents processed by the Patent Bots AI
• 36,824 (11.4%) patents with a perfect Patent Quality Score – up from 10.3% in 2023
• 6.75 average errors per patent – down from 7.9 in 2023
• 4 median errors per patent – down from 5 in 2023

The decline in errors per patent is not a one-year phenomenon. In fact, the average has declined nearly 25% in just five years – from 8.9 errors per patent in 2020 to an all-time low of 6.75 this year.

The decrease coincides with the rise of automated patent proofreading tools like Patent Bots Prep & Pros Pro. As more patent attorneys have implemented these tools into their workflows, the prevalence of errors has decreased steadily – and dramatically – year after year. 

That said, nearly 287,000 (88%) of all patents issued in the last year contained at least one numbering, antecedent basis, or word support error. If your firm doesn't use automated proofreading, try Patent Bots FREE for 14 days.

Now, on to the rankings!

2024 Patent Quality Rankings: Top 10 Large Firms.

We've segmented America's most active patent firms (those with at least 500 patents issued in the last year) into a Large Firms list to recognize their prolific patent practices. 

For the full Top 50 ranking of patent firms, keep scrolling! 

For the third consecutive year, Harrity & Harrity held the top spot in the rankings. Congratulations to Harrity & Harrity and the rest of these large firms for doing amazing work over the last year! 

(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.)

2024 Patent Quality Rankings: Top 50 Firms Overall.

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.

2023 Patent Quality Rankings: The Top 50 Companies

Patent Bots is pleased to announce its fourth annual Patent Quality Rankings of top companies. (We previously announced our Top 50 patent law firms and our Top 10 firms by Tech Center.)

We reviewed every patent issued by the USPTO in the past year – over 320,000! – using our advanced machine learning software. 

We then ranked more than 750 companies with 50+ patents issued based on the average number of numbering, antecedent basis, and word support errors detected in their patents. Our rankings are based only on these errors and do not address many other important aspects of patent quality. 

Patent Accuracy: By the Numbers.

Before we unveil the Top 50 companies, here's a quick 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.
