What is the statutory basis for interference proceedings in patent law?
The statutory basis for interference proceedings in patent law is primarily found in 35 U.S.C. 135 (pre-AIA). This statute outlines the process for declaring and conducting interferences. According to the MPEP:
“Whenever an application is made for a patent which, in the opinion of the Director, would interfere with any pending application, or with any unexpired patent, an interference may be declared and the Director shall give notice of such declaration to the applicants, or applicant and patentee, as the case may be.”
This means that when two or more patent applications or an application and an existing patent appear to claim the same invention, the USPTO can initiate an interference proceeding to determine which party has priority of invention.
