A: Patent Prosecution Highway (PPH)Different patent offices that cooperate with each other are required to recognize each other's examination results and expedite the examination of patent applications that meet the corresponding conditions.

That is, when at least one or more of the claims contained in the patent application filed by the applicant in the Office of First Filing (OFF) are determined to be licensable, A request for expedited review of a subsequent application can be filed with the Office of Second Filing (OSF).

Suppose that the Patent Office of State A and the Patent Office of State B agree to initiate A bilateral PPH project, in which an applicant first files an invention patent application in State A, and then requests that the earlier application be given priority, and files an invention patent application on the same subject in State B; At this time, if the applicant makes A request, the examiner of the Patent Office of State B can refer to the positive examination opinion of the examiner of the Patent Office of State A when examining the patentability of the invention, and quickly issue the notice of the first examination opinion or make the decision of authorization.

The benefits of PPH include: Save examination resources, shorten the examination cycle, accelerate patent authorization, save costs, high authorization rate.
