Patent Workbench™: A New File History Tool

Patent Workbench™ is a tool that I’ve come to know over the last few months. As I’ve used it, I’ve begun to get more and more excited about its capabilities, as it’s very different from other tools I’ve seen. Patent Workbench™ is a service that includes the Patent Workbench™ Reader. This service allows users to analyze and manipulate patent file history information – all of the paperwork, correspondence, and references included in the prosecution of a patent application with the patent office – using a special file history package prepared by Landon IP. Having the benefit of seeing the tool early (full disclosure: Patent Workbench was created by the parent company of Intellogist®, Landon IP), I’ve noticed some features that I think the Intellogist Blog Audience will be interested in learning about.

The goal of this blog post isn’t to sell you anything (trying Patent Workbench™ is free), but to view Patent Workbench™ from the eye of someone familiar with handling and manipulating patent file histories. Always wish you could take collaborative notes on a file history? Compare versions of claims throughout the prosecution history? Easily search through the entire file history at once?

Read on to find out how Patent Workbench™ can accomplish those tasks quickly and easily!


Taking collaborative notes on a document can be difficult and frustrating to coordinate. Passing the file around, making sure versions are coordinated, and ensuring that notes are uniform and helpful to the other collaborators is a tough task. Of course, this assumes that you have the entire document (a file history, in this case) in a format that can be easily annotated by everyone that needs to provide input. By providing a common file format and annotation system, Patent Workbench™ solves part of the problem right off the bat. To take notes with multiple collaborators, users need only to load the Patent Workbench™ file (which contains all of the annotations, PDF documents, and other formatting) and specify their desired user name during Patent Workbench™ Reader start-up. Once inside Patent Workbench™ Reader, users can take notes on any part of the file history, or make general notes on the entire file history.

Note on the Interview Summary

Add Note buttons are present throughout the interface to allow users to make notes on any part of the file history.

These notes are uniformly formatted with a field for note name and content as well as automatically populated fields for date/time created (including author). Notes, like the rest of the Patent Workbench™ file, are fully searchable.

One of the neatest (in the true nerd sense) parts of Patent Workbench™ is the Claims Matrix feature. The Claims Matrix is one of three analysis tools available to Patent Workbench™ users, along with Evolved Claims and Claim Comparison (we’ll have to get to those some other time, or let The Patent Workbench™ Blog handle it!).

The Claims Matrix shows a complete set of claims for the patent as they have been modified over the course of the file history. In addition to seeing all of the claims side by side (or a subset), users can choose to enact a text comparison algorithm. This algorithm visually displays exactly how claims have changed from one iteration to the next.

This is just once small part of a vast Claims Matrix, showing changes from one version of a claim to the next.

The search feature within Patent Workbench™ is notable because it works with the entire file history, related reference PDFs, and your annotations. There are many search options including Boolean logic, stemming, and fuzzy searching. Results are shown according to relevancy or date, and keyword-in-context examples link directly to the PDF reader within Patent Workbench™, where results are automatically highlighted and indexed within the original documents.

Inside the PDF viewer, results are bookmarked and indexed for easy navigation just like the reults hit list.

This isn’t an exhaustive dissertation on these features of Patent Workbench™, but hopefully I was able to point out some of the features that I was impressed by. Thanks for reading!
