An Infringement or Non-Infringement Search identifies patents having claims that may read on a prospective product or service.
Prior to conducting the Infringement / Non-Infringement Search, Cardinal’s research team will work with you to establish the features of the product or service that should be considered for infringement. With this information, our experienced analysts will conduct a search, identify relevant patents, and highlight claims within the relevant patents in the search report. The Infringement / Non-Infringement Search scope may be limited to active U.S. patents, or may be expanded to include foreign patent references.
