Patent Validity or Invalidity Search

1. We keep drilling until we hit a dead end.

As our name reflects we use an ensemble approach to validity studies — powerful search tools and proven techniques for uncovering prior art. We search digital and physical libraries, perform full-text searching in six languages, and utilize the best commercial patent search software. We continually test all the known AI-assisted patent search systems to supplement what our human analysts find and review.

We don’t stop at the computer. We go beyond traditional search methods and machine translations. Our “leave no stone unturned” approach extends the search beyond traditional resources:

  • Manual searching at libraries for obscure journals, product catalogs, dissertations and theses.
  • In-country, native language searching of traditional and non-traditional patent and non-patent literature sources.
  • Primary research and the legwork to validate publication dates, release dates, and uncovering publicly available, but near impossible to find, documents.
Customize Patent Validity Search

2. We understand your reasons for needing a search and customize the approach to your needs.

We do not believe in a one size fits all approach to patent searching. Your needs and reasons for requesting a search are unique, as is the technology of interest. Our consultative scoping process ensures that your specific requirements and the intricacies of the technology are understood and addressed in the search process and in the final report.

Whether you are asserting or defending an infringement claim, preparing an Inter Partes Review (IPR) submission, or evaluating the strength of a portfolio, our approach ensures you get the proper strategy for your needs.
