Invalidity Searches

Invalidity Searches
DexPatent’s invalidity search helps you to identify prior art – i.e., patent and non-patent documents – to invalidate the claims of granted patent which the patent examiner may possibly have overlooked during examination. The search helps you in litigation and licensing related negotiations.

When is an Invalidity Search needed?

Examples & use cases of an Invalidity Search

Invalidity Searches
Invalidate a patent

A software company has been sued for patent infringement. In response, the company hires DexPatent to perform a search to invalidate the patent of the accuser.

Licensing Negotiations

An electronics company is considering licensing a patent for a new technology and wants to assess its validity and strength before entering negotiations. The company seeks DexPatent to perform an invalidity search to uncover prior art that weakens the patent's claims, potentially leading to more favorable licensing terms.

Patent Portfolio Evaluation

An automotive company requests DexPatent to conduct invalidity searches to assess the strength and validity of their own patents. This helps them to identify patents that may not be very strong and make informed decisions about which patents to maintain or deny.

Relavant patent laws and sections

When we do an invalidity search, we try and find prior art in proving anticipation under 35 U.S.C § 102. Such patent-invalidating prior art meets every limitation of a targeted claim.
If locating § 102 art proves elusive, we try and find prior art for obviousness under 35 U.S.C. § 103.
