What is the Patent Prosecution Highway?
The Patent Prosecution Highway (PPH) is essentially a work-sharing program that is set up among various patent offices throughout the world. The goal of the PPH is to reduce the time and expense to applicants by allowing patent offices to rely on the work performed by other patent offices.
If you have an issued U.S. patent or an opinion for your PCT application indicating that the invention is patentable, then the PPH may be a good option for any foreign patent applications that are filed for that same invention.
