2025 Patent Quality Rankings: The Top 50 Patent Law Firms

Patent Bots is excited to announce our sixth 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 – more than 314,000 this year! – by the USPTO in the past year. 

We then ranked the 710 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. 

The State of Patent Accuracy in 2025.

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

• 314,170 patents processed by the Patent Bots AI
• 38,531 (12.3%) patents with a perfect Patent Quality Score – up from 11.4% in 2024
• 6.55 average errors per patent – down from 6.75 in 2024
• 4 median errors per patent

The decline in errors per patent is not a one-year phenomenon. In fact, the average has declined by over 25% in just six years – from 8.9 errors per patent in 2020 to an all-time low of 6.55 this year.

The decrease in errors coincides with the rise of automated patent proofreading tools like Prep & Pros Pro by Patent Bots. 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, more than 275,000 (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!

2025 Patent Quality Rankings: Top 50 Patent Law Firms. 

Congratulations to Patent Bots customer GTC Law Group for jumping from No. 11 in our 2024 rankings to place first among firms with 50+ patents issued. (Our founder Jeff O’Neill was formerly a patent attorney for GTC Law Group.)

“We require our people to use Patent Bots. It is not an optional tool,” GTC Law Group principal and patent strategy specialist John Monocello said. “Quality is not just a philosophy. It’s a methodology. By requiring technology use at critical points in the process, we've been able to ensure high quality and accuracy.”

Note: 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.

Q&A with FIG. 1 Patents Founders Mark Niemann and Patrick Walsh

Mark Niemann and Patrick Walsh founded FIG. 1 Patents in 2021 with a focus on quality. That focus paid off this spring as FIG. 1 earned the top spot in our 2024 Patent Quality Rankings of patent law firms with 50+ patents issued in the previous year. 

FIG. 1, which has used Patent Bots proofreading since 2022, achieved a 99.6 patent quality score across 266 patents obtained. In addition to its top ranking among firms with 50+ patents, the firm also ranked second for USPTO Tech Centers 2100, 2600, and 3600.

Mark and Patrick recently shared their insights on patent quality and the strategies that led to their top ranking. The interview has been edited for length and clarity.

Patent Bots: First of all, congratulations on placing first in the rankings. Why is patent quality such a priority for your firm? 

Mark: Thank you! For us, it’s a fundamental mindset. When we established the firm, we believed that a strong emphasis on quality would set us apart from larger firms.

Producing error-free work is an established expectation within our firm. Our talented attorneys are committed to using Patent Bots for proofreading, and every piece of work is also reviewed by a partner who also employs the tool. We don’t send out work unless it meets our standard for quality.

PB: Your firm ranked 25^th in 2022 before you even began using Patent Bots. So, obviously, there’s more to quality than technology.

Patrick: Absolutely. Since our founding, one of our pillars has been drafting high quality patents without these errors. The reason we landed in the rankings initially is because we were doing the things that good patent attorneys are trained to do.

Patent Bots helped us rise to that next level and improve from a 90.8 score in 2022 to 99.6 in 2024. When you’re proofreading an application manually, it’s pretty easy to miss one or two little errors. Patent Bots prevents that from happening and helps you get that last little bit closer to error-free.

It's like running spell check on a 50-page document. You see the squiggly lines on your screen and you immediately see that something’s not right in your document.

PB: How do you incorporate your commitment to quality into your sales efforts? Are your clients aware of your high ranking?

Patrick: They’re totally aware of it. We promote our ranking in our marketing materials and we’ve even had potential clients reach out to us after initially seeing us in the rankings.

We don’t hide the fact that we use Patent Bots. When we send the patent draft to the client, we also often send a PDF of the Patent Bots proofreading report along with it. Some of our clients have even asked us to run reports on issued patents that were prepared by other firms to determine how well they’re positioned with an asset to weigh various portfolio strategies involving the asset.

PB: We use the phrase Patent Quality Rankings but there’s obviously more to patent quality than removing errors. How do you view the idea of patent quality? 

Mark: That’s absolutely correct. Our clients' continued business demonstrates their trust in us to deliver value beyond just error-free patents.

They rely on us to draft strong patents with strategic claims. They trust us to position their patents competitively in the market.

So for us, quality extends far beyond merely avoiding errors. Producing error-free work is just the first layer.

That said, if a firm scores low in the Patent Quality Rankings, what does it say about the deeper substance of that work?

2024 Patent Quality Rankings: Top 10 Firms in Each USPTO Tech Center

Patent Bots recently announced its fifth annual Patent Quality Rankings of top patent law firms. In April, we unveiled the Top 50 Patent Firms. 

Today, we'll announce the Top 10 firms in each USPTO Tech Center. 

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 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 287,000 (88%) of patents contained at least one detectable 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: 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. 

Large firms don't have a monopoly on patent accuracy. In our Top 50 overall rankings, 43 firms had fewer than 500 patents issued, 31 had fewer than 200 issued, and 14 had fewer than 100 issued. 

Congratulations to Patent Bots customer FIG. 1 Patents for jumping all the way from No. 8 in our 2023 rankings to the top of our 2024 list.

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.
