Major Recent Updates

November 2012

According to an email from a LexisNexis representative regarding the implementation of the CPC (Cooperative Patent Classification) on Lexis.com and TotalPatent:[1]

There are excellent benefits to be derived from moving to the CPC. It does, however, require a substantial rewrite of our classification data to become fully CPC-compliant. Since LexisNexis currently hosts patent data on two platforms—the legacy offering at lexis.com (that you have been using) and a much more robust offering on our flagship patent search platform TotalPatent, we will be rewriting the classification data for TotalPatent, but not for lexis.com.

Before January 1, 2013, we recommend that lexis.com patent users who do research based on patent classification do that research on TotalPatent. We are committed to making the process as easy and effortless for you as possible. The end result will certainly be a superior user experience, thanks to the patent-specific nature of the TotalPatent interface.

Here are the key details:

  • No new IDs—You’ll be able to use your current lexis.com ID/PW to access TotalPatent. In fact, there is a link to TotalPatent on the right-hand side of the lexis.com Patent Area of Law page that will open TotalPatent with one click.
  • No additional charges for standard Boolean searching/downloading in the patent databases already included in your lexis.com flat-rate contract through the TotalPatent interface.
  • Personalized assistance and training from the IP User Experience team members to help you transition your research to the TotalPatent platform as well as any Alerts that you might have.

Patent Databases on lexis.com®

The U.S. patent databases on lexis.com cover all U.S. patents issued by the USPTO. That is, all granted patents from 1790 to present and all U.S. pre-grant publications (applications) issued from 2001 to present are available on lexis.com. Newly issued granted patents and pre-grant publications are available online within 24 hours of publication by the USPTO.

U.S. patents on lexis.com are enhanced with fully searchable value added information. New litigation notices from CourtLink are added weekly. These notices are incorporated directly into the text of the patent. Also included are the weekly USPTO’s Official Gazette status changes (i.e., expirations, extensions, reissues, reexamination requests, etc.); weekly assignee updates; and bi-monthly class updates.

Other popular enhancements to U.S. patents on lexis.com are the full sets of drawing sheets and the PDF of the official patent. Links to the drawing sheets and the PDF are on the user interface. They are available for immediate viewing and printing; they do not have to be ordered through a separate document delivery.

In addition to U.S. patents, lexis.com also offers the full date range of the top non-U.S. authorities: European Patents, Patent Cooperation Treaty Patent Applications, Patent Abstracts of Japan, and United Kingdom Patent Applications. Non-U.S. patents on Lexis are enhanced with a link to the PDF of the official patent.

All patent authorities on lexis.com have extensive search capabilities, including:

  • Over 100 searchable fields and robust Boolean search logic allowing for pinpoint accuracy in complex searches.
  • Natural Language search logic allowing the user to enter a search in plain English without using any special terms or connectors. The natural language feature's document relevance ranking gives the user quick access to the most pertinent documents in the search results.
  • The new interactive Semantic Search feature powered by PureDiscovery provides additional user-controlled search terms to enhance the user's Boolean logic
  • Core Terms display shows the most prominent words and phrases that appear in a patent.
  • The “More Like This” feature creates a new search using the original search words or Core Terms that appear in a patent. The new search finds more patents similar to the patent retrieved by the original search.
