I. Introduction
Patent Prosecution Highway or PPH is a set of initiatives promulgated by participating patent offices around the world to accelerate patent prosecution in countries of the participating patent offices. PPH allows the participating patent offices to share information and to benefit from work performed by other participating patent offices, and thereby reducing examination workload and improving quality of patents.
Under PPH, prosecution of a patent application previously filed with a participating patent office can be fast-tracked in another participating patent office if the patent application meets certain requirements. This article provides a brief overview of benefits of filing patent applications under PPH and requirements by which the patent applications must satisfy in order to participate in PPH.
