2022 Patent Bots Quality Rankings: The Top Companies

Patent Bots is pleased to announce its third 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 300,000! – using our advanced machine learning software. 

We then ranked nearly 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. 

(If your company is not on the Top 10 lists below, review our full list inside our PatentVerse. If your company is ranked outside the Top 50, you'll need to log in as we don't want to publicly identify companies with lower scores.)

2022 Patent Quality Rankings: Top 10 Large Companies.

Cisco Technology ranked first among companies with 250+ patents issued in the last year. Cisco, which patented 903 inventions in the last year, began using the Patent Bots automated proofreading solution in 2018.

Sony Semiconductor Solutions and Kyocera Document Solutions ranked second and third, respectively, among large companies. They were followed by Yazaki Corporation, Seiko Epson Corporation, AT&T Intellectual Property, Semiconductor Energy Lab, Toyota Motor Corporation, Western Digital Tech, and Qualcomm Inc.

Congratulations to Cisco and the rest of these large companies for doing amazing work over the last year! 

2022 Patent Quality Rankings: Top 10 Mid-Sized Companies. 

Large companies don't have a monopoly on patent accuracy. Among mid-sized companies with between 100 and 249 patents issued, the top three patent quality scores were held by Zoox Inc., IGT, and Haier US Appliance Solutions, respectively.

They were followed by Nanya Technology Corporation, JTEKT Corporation, InnoLux Corporation, Commvault Systems, Zeon Corporation, SanDisk Technologies, and Snowflake Inc.

Patent Accuracy: By the Numbers.

The Patent Quality Rankings are based only on average number of numbering errors, antecedent basis errors, and word support errors in issued patents and don't address other important aspects of patent quality. Here's a quick look at the state of patent accuracy.

• 322,000 patents processed by the Patent Bots AI
• 16,434 patents achieved a perfect Patent Bots Quality Score
• 11.2 average errors per patent
• 7 median errors per patent

More than 305,000 patents issued 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.

New Feature! Simplify Review of Prior Art with Office Action Explorer

One of the most tedious aspects of Office Action response is juggling documents while reviewing prior art of 102/103 rejections. 

Our new Office Action Explorer simplifies this workflow by displaying an application’s most recent office action, pending claims, and cited prior art side-by-side-by-side in a three-column interface. 

Office Action Explorer is available today at no additional charge with your existing Patent Bots Prep & Pros Pro subscription. 

Office Action Explorer: How It Works.

Simply enter your patent application number and Patent Bots will show the most recent office action and pending claims automatically in the first two columns.

Your patent application must be public. We expect to expand the feature to non-public applications soon. 

Now for the best part… Patent prior art references are hyperlinked in the Office Action column. When you click on a prior art reference, Patent Bots will show the prior art in the Prior Art column. Even better, citations to paragraphs and column/line numbers are also hyperlinked. When you click on a citation, we'll automatically scroll the third column to that specific citation. 

This enables you to easily understand the basis for the rejection and prepare your office action response. 

See the NEW Office Action Explorer in action in the short video below. Then, use Office Action Explorer for your next office action response! 

2022 Patent Bots Quality Rankings: Top 10 Firms in Each USPTO Tech Center

Patent Bots recently announced its third 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 300,000! – 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 95% 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. Try Patent Bots FREE for 14 days.

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.

2022 Patent Bots Quality Rankings: The Top 50 Patent Law Firms

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

We used our advanced machine learning software to review every patent issued – over 300,000! – by the USPTO in the past year. We then ranked the 736 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.

New Feature! Stop Juggling Documents in Office Actions

Juggling documents – application, office action, prior art, etc. – is one of the most tedious parts of Office Action responses.

To reduce that burden, Patent Bots proofreading results now display the text of the most recent Office Action from the USPTO. Here’s how it looks on your screen:

How do we do it? By extracting the application number from your response, we’re able to access the text of the Office Action from the USPTO.

Your patent application must be public … and the USPTO’s website must not be crashing. 🤣

This new feature is just the beginning. Soon, our NEW Office Action Response tool will also display the text of your application and the text of cited prior art – all in one convenient user interface.

Stay tuned!
