Patent Search & Research

Validity Search
or Invalidity Search
or Enforcement Readiness Search

An Invalidity or Validity Search is conducted to find prior art references to contest the validity of the claims of a patent or published patent application. Searching includes US and foreign patent/published application databases as well as non-patent literature databases for references disclosing the limitations of the claims before the priority date of the patent.

Our experienced search professionals select relevant prior art references from these search results and provide excerpt segments of the references to highlight their relevance in the search report. In addition, search professionals can provide an analysis of the claims by breaking down the claims into their limitations and then mapping the relevant segments from the references to the corresponding limitations of the claims.

Typically, Invalidity or Validity Searches are completed within 4-5 business days and cost between $1400 and $1700, plus $100 to $150 for analysis.
