Patent prosecution generally refers to the process of responding to the requirements set in written communications from the patent office. The patent prosecution begins after a patent application has been filed and concludes with a grant or a rejection of a patent. We provide end-to-end services that include filing patent applications, responding to the communications from the examining patent office, and close monitoring of pending patent applications. Patent prosecution may involve additional acts such as handling pre-grant oppositions from competitors, filing appeals with the Controller/Commissioner of the patent office and/or appellate boards, preparing exhibits, and attending hearings.
