LexisNexis® PatentOptimizer™ is a patent analysis tool created by LexisNexis and designed to facilitate the patent application process. The main feature of PatentOptimizer is analyzing the language used within the document to make sure it is consistent and inclusive of such legal concepts as antecedent basis.[1] According to the LexisNexis website, PatentOptimizer can be:[1]

  • Integrated into Microsoft® Word, Internet Explorer, Adobe® Acrobat® 8.0 and Adobe® Reader® 8.0.
  • Supports patents published on the following services: TotalPatent™,®, and
  • Leverages LexisNexis content, including enhanced full-text patent information, post issuance data, federal case law and administrative rulings, Matthew Bender® Attorney’s Dictionary of Patent Claims, EI Compendex® Thesaurus, and a variety of other sources and forms.
  • Consolidate your analyses into a “one click” error report that is fully customizable.

Another major point of interest is that PatentOptimizer can compare two different versions of a published document (e.g. different publication stages of a patent application), highlighting any changes or inconsistencies between the two versions.

Also included in PatentOptimizer is the PatentOptimizer™ Analytics (PDF) feature set, which allows users to:[2]

  • Filter, rank and sort patent collections by various key data, such as inventor, examiner, legal representative, assignee, class, date, etc.
  • Navigate and review ranked lists of extracted claim elements, parts, terms, phrases and definitions.
  • Perform statistical and substantive analysis of the claims contained in a large patent portfolio.
  • Generate claim charts in Microsoft® Excel® for multiple patents.
  • Locate specific synonyms utilized across an entire portfolio.
  • Create spreadsheets based on tool findings and specific user-identified criteria.

User Tips

It should be noted that PatentOptimizer will report out in the Check References feature if a patent has expired due to failure to pay maintenance fees.[3] However, if a patent expires due to its natural expiration date, then PatentOptimizer does not report that out.[3] The information for Check References is obtained from the Official Gazette of the USPTO and LexisNexis Courtlink (for litigation filings). Since normal term expirations aren't included in either source, they aren't displayed in the Check References section either.[3]
