Collaborative Search Pilot Program (CSP)


USPTO's Expanded Collaborative Search Pilot


For a limited time, and at no extra cost, you can join those in your industry using the Collaborative Search Pilot Program (CSP) to get expedited, consistent IP protection.


CSP provides those cross-filing their patent applications internationally with search results from multiple Offices early in the examination process so the applicant can determine their next steps in patent prosecution.

Due to the success of the initial CSP, the USPTO started an expanded CSP on November 1, 2017.  CSP combines the most successful characteristics and user feedback from our initial pilot into a single process for each participating Office.

Are you ready to incorporate CSP into your international patent filing strategy?
