Examination Search

An Examination Search is performed on the claims of a patent application prior to filing. The results help you prepare your application for upcoming prosecution, allowing you to adjust claims and the specification in light of the identified prior art.

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. Cardinal’s experienced analysts highlight segments of particular relevance in the identified references. Upon request, these highlighted segments can be mapped to your claim elements.
