Patent Claims Analyzer

Patent Claims Analyzer

I have released a big update to the free Chrome browser extension “Patent Claims Tree” which was first published back in 2012. The latest version of this tool is called “Patent Claims Analyzer” to reflect richer functionality and includes a number of new features and enhancements that I find handy during patent analysis, including:

  • There is an added ability to hide dependent claims
  • It is possible to show independent claims text for ease of referencing claims while simultaneously reading the patent specification
  • For Google Patents you can select an independent claim to scroll the webpage to that claim
  • A copy option copies text for a selected independent claim for convenience in pasting elsewhere
  • There is an optional “Save as Chart” feature that creates a pre-populated claim chart document — this works best for Google Patents
  • Settings functionality and flow is improved

The Patent Claims Analyzer tool is a Chrome browser extension that displays patent claims information for all patent claims listed on a current webpage, such as:

  • Independent claim numbers
  • Independent claim word count
  • Independent claim type (best effort)
  • Independent claim text
  • Dependent claim numbers
  • Hierarchical dependencies
  • Priority date (Google Patents only)
  • Several helpful links, such as USPTO Assignments, USPTO Maintenance info, Global Dossier, Espacenet, EPO Patent Register, EPO Federated Register, Google Patents Prior Art Finder, and more

The tool provides interactive features, such as:

  • Hide/Show dependent claims
  • Show/Hide independent claim text
  • Copy independent claim text
  • Scroll to claim in webpage (US patents in Google Patents only)
  • Export pre-filled claim chart

Select the red claims tree icon on the right side of the address bar in the Chrome browser to see a patent claims tree and associated details. Patent Claims Analyzer - 128x128

Currently supported on the following websites (at least partially):

  • USPTO
  • Google Patents (.com, .de, .fr, .co.uk, .se, .ca, co.in, co.nz currently — send me requests for additional countries). Currently US, EP, WO, and CA patent documents are handled. A future update will also handle documents from other jurisdictions such as DE.
  • FreePatentsOnline
  • Espacenet

I do my best to present the claims trees and information correctly, but I cannot guarantee results because the supported websites are dynamic and often changing — so PLEASE LET ME KNOW OF ANY ISSUES YOU ENCOUNTER. The extension is provided ‘As-Is’ without any express or implied warranty of any kind.

The extension should work for a webpage loaded after the initial installation of the extension, as long as JavaScript is enabled.

Privacy: Note that no information is transmitted from the extension — all webpage data handling is done only at your local browser in the extension. This and other Chrome extensions from Wolf Mountain IP are provided free for use for the benefit of fellow members of the patent community.

Multiple dependent claims are not currently fully supported. Also, only claims in English are currently fully supported. Some basic French and German handling is provided.

Visited links on Google Patents pages are highlighted, facilitating review projects.

EPO Patent Search Matters

I will be attending 2019’s European Patent Office (EPO) “Patent Search Matters” training event in Munich, Germany on May 7 and 8. I hope to see you there!

From the EPO:

The next in the EPO’s “Search Matters” series of annual training events will be held in Munich from 6 to 8 May 2019. This event provides patent search professionals with a unique opportunity to gain an insight into the EPO’s search strategies and techniques and to learn more about industry-specific searches.

At a total of 26 workshops run by patent examiners, participants will be able not only to take a closer look at a wide range of topics, including the impact of AI and blockchain on searching, search strategies and Asian prior art, but also to find out more about search tools such as Espacenet and PATSTAT and explore the complexity of searching in the automotive, ICT and chemistry fields. The programme includes plenary lectures and a round table on searchers’ hopes and fears and the future of searching in an AI and blockchain landscape.

In addition, at the much-sought-after “at-the-desk” sessions, to be held on the afternoon of 6 May, before the main event officially starts, participants will have a chance to talk to EPO examiners about approaches to searching in specific technical areas which they can select when registering.

Patent Deception

NPR’s Planet Money released an episode covering invention/patent scams, primarily focusing on World Patent Marketing. It’s a sad and cautionary tale. Be sure to leverage an experienced patent practitioner (searcher, agent, attorney) before engaging with one of these marketing companies.

The US Patent and Trademark Office (USPTO) also has a “Scam Prevention” page worth checking out to learn how to avoid getting scammed.

US Patent Term (Expiration Estimation)

It can be somewhat tricky to accurately estimate when an issued US patent should expire. Nowadays, there are plenty of software solutions that automatically perform this calculation so you don’t have to. For example, AcclaimIP provides the calculated patent expiration date. But if you do not have access to such a solution, fear not — you need not calculate the expiration manually. The USPTO provides a Microsoft Excel spreadsheet called “Patent Term Calculator” with associated instructions — you just need to find the indicated information and input it into the spreadsheet to have the expiration date calculated.

According to the USPTO:

The United States Patent and Trademark Office does not calculate expiration dates for patents. In response to patent owner and public inquiry, the USPTO is providing a downloadable patent term calculator as a resource to help the public estimate the expiration date of a patent. The calculator can be used to estimate the expiration dates of utility, plant, or design patents. The calculator contains prompts to enter specific information related to the patent in order to help in estimating expiration dates. [Link]

Stupid Patent of the Month

If you haven’t already run across the Electronic Frontier Foundation’s Stupid Patent of the Month “award,” I can recommend checking it out so you can be entertained by each month’s winner. The EFF even has a “Mark Cuban Chair to Eliminate Stupid Patents”. The most recent month’s selection for Stupid Patent of the Month is US 9,069,648, which the EFF outlines as follows:

The patent describes sending “motivational messages,” based “on the current or anticipated activity of the user,” to a “personal electronic device.” The patent provides examples such as sending the message “don’t give up” when the user is running up a hill. The examples aren’t limited to health or exercise. For example, the patent suggests sending messages like “do not fear” and “God is with you” when a “user enters a dangerous neighborhood.” [Link]

eBook “Patent Mining Searches”

I have published an eBook titled “Patent Mining Searches” — it’s available via Amazon.com for any device via Kindle. It’s available for free via Kindle Unlimited.

“Patent Mining Searches” is intended for patent searchers, analysts, and researchers who mine for relevant and valuable patents.

“Patent Mining Searches” is a go-to quick reference, and the book explains:

  • types of patent searches
  • mining search processes
  • mining search tips
  • use of metrics in mining searches
  • search and analysis tools

Google Patents Widescreen Viewer

UPDATE (Jan 15, 2018): Ian and the great team at Google have rendered this extension unnecessary as of this writing. The sidebar is now collapsible, and there is a search bar on the top. The new figure viewer is very flexible and allows for expanding a figure to the needed width. There has also been a big JavaScript refactor and use of gzip to speed up page loading significantly. Excellent work!


Today I published a new Chrome browser extension called “Google Patents Widescreen” that makes Google Patents (patents.google.com/patent/) much more readable. The left-side search column is hidden, the text area is widened, and images are provided at greater resolution for readability.

A resolution width of 1920 works very well, though all narrower widths also provide improved readability.

Once it’s installed in Chrome, you don’t need to do anything — all Google Patents patent pages (with this syntax: patents.google.com/patent/) will automatically be modified for alternate presentation.

Note that the extension doesn’t send out any data, and in fact there’s no JavaScript — it’s purely just formatting tweaks.

Here’s the different in presentation from the normal view versus the extension’s enhanced view:
