Our Standard Invalidity or Validity Search identifies prior art references that may be used alone or in combination to contest the validity of the claims in a patent or patent application.
Standard Invalidity or Validity Search results may include published applications and issued patents, both U.S. and foreign, as well as non-patent literature such as scientific journals and papers.
Only references disclosing the claim limitations are included in the results, and Cardinal’s analysts highlight the segments relevant to the claim elements. Additionally, analysts can provide a mapping between the highlighted segments and the corresponding claim limitations.
