Cardinal can provide a Freedom to Operate Search or Clearance Search to identify patents and published applications that may pose an infringement risk to your product or service, as well as expired patents that may indicate that your product or service is in the public domain.
Depending on your needs, the Freedom to Operate Search or Clearance Search scope may be limited to U.S. patents and published applications or expanded to include foreign patent references. Expired patents and public domain evidence can also be considered and the status of each U.S. Patent is provided.
*Cardinal uses a mathematical algorithm to determine an estimated patent expiration date.
This is for convenience only and is not a legal determination of the exact expiration date.
**Prices vary with extent and overlap with existing features.
