Methodology: How our rankings work
We know that each technology center at the USPTO presents its own unique set of challenges. Perhaps more importantly, we know that firm expertise in a specific field is often more sought after than general aptitude. So, rather than ranking firm performance across the entire USPTO, we narrowed in on each tech center to find the best of the best within each particular area.
Juristat's rankings consider both volume and performance in that specific technology center. We based the rankings on how well a firm performed in three key metrics over a 12-month period. These metrics are:
- Number of applications filed
- Allowance rate
- Average number of office actions before allowance
The analysis includes public applications disposed (or in the case of the first metric, applications filed) in a designated 12-month time frame. To account for the 18-month publication delay, the analysis looks back at a previous timeframe so that we’d have the most accurate and comprehensive dataset possible. The specific dates analyzed can be found on individual ranking pages.
To qualify for inclusion, a firm must have filed a minimum of 50 applications in the specific tech center during that time period. (Note: For the 2019-2022 rankings, this requirement was 100 applications.) This ensures the firm has extensive experience in that technology center and provides an appropriate-sized dataset to evaluate performance metrics. For our analysis, we attribute applications to the firm listed on the application at the time of disposition. We also exclude foreign priority applications and design applications from this analysis.
We narrow the field in each technology center by first identifying the top ten firms in each of three categories – allowance rate, average office actions before allowance, and volume of applications filed. As you look at each tech center’s rankings, you see the top ten in each of those three key metrics, as well as our overall ranking – the Juristat Rank. This overall rank was calculated by taking into account the firm’s rank for the key metric, as well as rewarding firms who ranked for more than one category. This gives us a better picture of which firms have the most well-rounded performance in each tech center. Read more in our FAQs below.
A caveat, of course. This method is but one way to measure a firm’s performance and is not intended to be definitive. In fact, you should not rely solely on a firm’s filing volume, allowance rate, or number of office actions as a measure of success - as that doesn’t necessarily account for patent quality. Beyond that, many clients value timeliness, communication, retention of top talent, or adoption of new technologies – more qualitative measures we can’t yet analyze with data.
Additionally, these rankings represent a snapshot of performance at the time of analysis. Make sure you have the most up-to-date performance metrics by subscribing to Juristat.

No! Firms do not have to use Juristat, nor do they need to apply to participate in the rankings. The Top Patent Firm rankings are powered by our industry-leading database of more than 10 million patent applications. This is the very same database that makes our tools so robust.
Design patents tend to have higher-than-average allowance rates, which can throw off the analysis. Comparing a firm that does all utility patents with a firm that has even one design patent would put the latter at an advantage. As you noticed, we also skipped ranking firms in TC 2900, where most/all the design patents are assigned.
Similarly, we exclude foreign priority applications to level the playing field for the analysis as foreign priority applications generally have a higher allowance rate.
To qualify for inclusion, a firm must have filed a minimum of 50 applications in the tech center during the time period studied. This ensures the firm has extensive experience in that technology center and provides an appropriate-sized dataset to evaluate performance metrics.
Keen observers may notice that previous iterations of the rankings (2019-2022) set the threshold at 100 applications in a single year in the specific technology center. At such a high filing requirement, we felt the list was favoring large firms and that many firms with excellent performance metrics were ineligible because they had filed just under 100 applications.
For the 2024 rankings, we opted to change the threshold of our ranking methodology to 50 applications filed in the specific technology center in a single year. This is still a significant filing volume to demonstrate expertise and an appropriate-sized dataset to evaluate performance metrics.
No, Juristat's rankings consider both volume and performance in that specific technology center. We based the rankings on how well a firm performed in three key metrics over a 12-month period. These metrics are: Number of applications filed, Allowance rate, Average number of office actions before allowance. A firm is required to have filed at least 50 applications in the specified technology center in the one-year time frame to be eligible for the rankings.
No, allowance rate is just one way to measure a firm’s success at the USPTO. Juristat's rankings consider both volume and performance in that specific technology center. We based the rankings on how well a firm performed in three key metrics over a 12-month period.
These metrics are:
- Number of applications filed,
- Allowance rate,
- Average number of office actions before allowance.
This list (and all those featured on our blog) are powered by our database of more than 10 million patent applications at the USPTO. Our database includes global and foreign law firms to the extent they prosecute applications under their own name in the United States. Many foreign firms choose to file applications through another U.S. firm and may not be included in this analysis.
If your firm did not rank, it could be for a number of reasons.
- You may not have been one of the top-performing firms in that technology center for the specific key metrics we examine.
- Your firm may have been excluded because you didn’t have 50+ filings in the particular technology center during this time period. Keep in mind, this analysis only considers published applications and excludes design and foreign priority. Credit is given to the firm at disposition as listed on the final application. Or,
- Each edition of Top Patent Firms is based on data available at that time. These lists went through extensive review and quality assurance before publishing. Keep in mind, however, Juristat is constantly reprocessing to pull in new data. This gives our clients access to the most robust patent database on the market. It also means that specific metrics tend to change slightly over time as more information is added into the dataset. Juristat is constantly acquiring data from multiple sources, including Patent Center, Global Dossier, PEDS, the weekly Publication and Issuance Gazetteers, the Assignments data feed, and more.
While we do not publicly share the raw data or rank for every firm, this data was all compiled using Juristat Analytics. Our powerful search and filtering capabilities, along with the ability to quickly export large datasets, make in-depth analysis like this possible. Additionally, our side-by-side intelligence reports make it easy to compare metrics from firms, companies, centers, art units, classes, and more. If you'd like to see how our competitive intelligence reporting works, set up a call with us.
There’s no call for participation or entry fee associated with our Top Patent Firms lists. These rankings (and all those featured on our blog) are powered by our industry-leading database of more than 10 million patent applications.

On the Archive page, you may notice we have 2019, 2020, 2021, 2022; this current list is 2024. At Juristat, we are committed to the integrity of our data, both in our product and in our annual Top Firms ranking. Maintaining that standard requires significant time and focus. In 2023, we made the strategic decision to focus on product development and customer success, and pause publishing our annual rankings. Now, with renewed capacity, we’re excited to resume the rankings in 2024, offering even more comprehensive insights for firms navigating the competitive patent landscape.
