When a patent application is filed with the USPTO, it is routed to a patent examiner with an appropriate scientific background. It may be one or more years before the examiner begins review of the application. Once the examiner begins review, he or she evaluates the application for conformance with the patent laws and regulations, in addition to determining whether the application is distinct from the “prior art” (i.e., earlier patents and publications). The examiner may, and often does, reject most or all of the patent claims in the first review. A C4C patent agent or outside counsel responds to the examiner’s comments, often after obtaining input from the inventors. In general, several rounds of patent examiner review and UW C4C response are required before a patent is granted or finally rejected.
