See our PatentVerse page to see how your firm does in comparison. Other than the top 50 firms, you can only see your own firm's ranking (we don't want to publicly identify firms doing lower quality work). Note that these rankings are based only on average errors in issued patents and don't address other important aspects of patent quality.

This is the final posting of our second annual release of patent quality rankings for law firms and companies. 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).

We rank the top 50 firms overall and also the top 10 in each USPTO tech center:

• Top 50 Overall
• Top 10 in Tech Center 1600
• Top 10 in Tech Center 1700
• Top 10 in Tech Center 2100
• Top 10 in Tech Center 2400
• Top 10 in Tech Center 2600
• Top 10 in Tech Center 2800

Congratulations to these companies for doing amazing work!

To improve your company's patent quality scores, use Patent Bots automated proofreading to remove errors in your work.

This is our second annual company patent quality rankings and is the latest release following our Top 10 Large US Law Firms for Patent Quality rankings.

For greater accuracy, Patent Bots Quality Scores are computed using only a few of the types of errors in our proofreading results: numbering errors, antecedent basis errors, and word support errors (words that don't appear in the detailed description).

Although we may over or undercount 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 company's work. See here for more details about our methodology.

Preview of New Patent Bots 2021 Patent Quality Rankings

Next week, Patent Bots will officially announce the 2021 edition of its Patent Quality rankings!  

We used our advanced machine learning to proofread an entire year of US issued patents and then ranked 787 law firms by the smallest average number of errors in the issued patents. 

Law firms can move up in the rankings by implementing processes to ensure higher quality work.  Using an automated patent proofreading tool, careful review of proofreading reports, and review by a second attorney will all help create stronger patents for your clients.

As a preview to announcing our 2021 Patent Quality rankings, we’d like to highlight a law firm who made one of the the biggest moves up in the rankings since 2020.

In 2020, Pierce Atwood ranked 33rd out of 802 law firms, an already impressive achievement.  In 2021, Pierce Atwood has performed done even better, moving up 20 spots to rank 13th for law firm patent quality out of 787 law firms. Pierce Atwood LLP is also in the top 10 law firms for patent quality in Tech Center 2600.  

Congratulations to the team at Pierce Atwood, who Patent Bots is proud to have as a client who uses our advanced proofreading tool.

Next week Patent Bots will showcase the top 50 US law firms with the highest patent quality rankings.

This is the first of a series of releases around our 2nd annual Patent Quality rankings, based on our advanced machine learning analysis of public USPTO data. 

To improve your firm's patent quality scores, sign up for a free trial of Patent Bots automated proofreading to identify and remove errors in your work.

Also, see our PatentVerse page to see how your firm ranks for patent quality against other law firms. Other than the top 50 firms, only you can see your own firm's ranking. Note that these rankings are based only on average errors in issued patents and don't address other potentially important aspects of patent quality.

More Patent Drafting Tools in Word

At Patent Bots, we are continuing to add more tools to supercharge patent attorneys and make them more efficient. With our Word add-in, we automate tedious tasks to allow you to increase profits (especially with fixed fee work), write higher quality patents, and make your work more enjoyable.

We've previously posted about our Ref Label Tracker that includes easy navigation, typing shortcuts, and updating of reference labels or the text associated with them.

We have two new more tools patent drafting tools to announce: figure number updating and patent application navigation.

Figure Number Updating

We have a new Figures tab in our Application Drafter panel:

In this tab, we show a list of figures in your application and navigation buttons to easily go to the figure numbers in your Word document. We also have a button to automatically change a figure number and its reference labels.

Suppose you send a final draft of a patent application to a client that has Figs. 1-6. The client wants to add a new Fig. 4 so you have to renumber Figs. 4-6 to Figs. 5-7 and change all of the reference labels. Ugh... We now make this easy!:

To change Fig. 6 to Fig. 7, just enter 7 in the gray box and we'll change all instances of Fig. 6 to Fig. 7 (or Figure 6 or FIG. 6). Even better, we'll also change all reference labels 6## to 7##, such as changing 610 to 710.

Patent Application Navigation

We have another new tab for easy navigation through parts of your patent application. We provide shortcuts for all common patent headings and the first instance of each figure in the Detailed Description section:

Suppose you are editing your claims, and you want to review the details of Fig. 3. Normally, it is tedious to get to the right part of the application. With our shortcuts, we take you there instantly. After reviewing Fig. 3, click the Claims shortcut to go back to the claims.

Our goal is to automate the tedious parts of patent preparation and prosecution to supercharge your workflow! We'll have a lot more like this in the coming months.

Usage Pricing Now Available

At Patent Bots, we want to make sure that our pricing provides great value for all our customers.

To that end, we now offer usage pricing for three of our products: Art Unit Predictor, Premium Statistics, and PatentPlex. Usage pricing is not available for Patent Proofreading since that product may be purchased with a monthly per-user subscription.

With usage pricing, no subscription is required, and you instead you pay each time you use the product.

Our usage pricing is shown on our pricing page and described in greater detail below:

• Art Unit Predictor - $499 for 24 hours. A single person has unlimited access to our Art Unit Predictor for 24 hours. There are no limits to the number of uses or the number of patent applications you use it with. You may not, however, automate access with a script or share a login with multiple people.
  
• Premium Statistics - $99 per examiner for 30 days. You get unlimited access to a single patent examiner for 30 days. Statistics for the examiner’s art unit and group are included as well (though other examiners in the art unit and group are not included).
  
• PatentPlex - $99 per patent for 30 days. You get unlimited access to our PatentPlex page for a single patent for 30 days. This includes all PatentPlex features, and is easily worth the cost with the time you save when creating a patent family tree or a patent claim chart.

Usage pricing provides better value for law firms in two ways:

• Law firms can use bill back to pass the costs of using Patent Bots to their clients who are receiving the ultimate benefit of our products.
  
• Law firms who have only the occasional need for our tools can receive the benefits of our products at lower cost.

For anything other than occasional use, however, our firm-wide subscriptions provide much better value.  We’ll use a law firm with 50 patent practitioners as an example.

If this 50-practitioner firm generates 1-2 patent family trees or claim charts a month, then the firm will pay less with usage pricing. If this 50-practitioner firm generates more than 2 patent family trees or claim charts a month, then it will pay less with a firm-wide subscription.

We hope you appreciate the addition of usage pricing. It was a lot of work on our part to set this up! Please contact us with any questions at sales@patentbots.com.

Word Add-In Awesomeness

One of our core values at Patent Bots is that we want our tools to be easy and even enjoyable to use. Your time is valuable, and we don't want to waste it. We spend an enormous amount of time thinking about our user interface and how to make it better to save you time.

Our Word add-in is an important part of making our patent proofreading easier to use, and we are excited to announce two cool improvements to our Word add-in. Our Word add-in now shows proofreading results within Word instead of opening a separate browser window. With this update, our proofreading results are able to interact directly with your Word document.

To get access to the new features described below, you need to have the latest version of our Word add-in. If you don't have it, you can force an update by uninstalling and reinstalling the add-in.  See our documentation for details.

AutoNav

The first new feature is called AutoNav. On demand, we automatically scroll your Word document to show you the part of the patent application you are reviewing in the proofreading results.

In the example above, the user is reviewing our proofreading results for claim 2. When you click the blue arrow, we automatically scroll the Word document to show you claim 2. This makes it very easy to jump to portions of the Word document and saves you time in reviewing proofreading results.

We include AutoNav arrows every time we show you text of the patent application in our proofreading results. Not only for claims, but also when we show you paragraphs of the specification for word support and reference labels. With a quick click, you are looking at the exact part of your application that you need.

Ref Label Navigation

We've added another navigation feature to our Ref Label Tracker. For each ref label, we've added four buttons:

• — Go to first instance
• — Go to previous instance
• — Go to next instance
• — Go to last instance

Using these buttons, you can easily cycle through each instance of a ref label in your patent application.

We'll be adding more Word add-in awesomeness throughout the year. Please let us know if there is anything in particular you would like to see!
