What is a requirement for a claim to be eligible for the Patent Prosecution Highway (PPH)?

For a claim to be eligible for the Patent Prosecution Highway (PPH), it is essential that the claim has the same or a similar scope to the claims that have been allowed in the Office of Earlier Examination (OEE). This requirement is in place to streamline the patent examination process and facilitate the sharing of examination results between patent offices. When a claim is submitted under the PPH, the applicant is essentially using the prior allowance from the OEE as a basis to expedite the examination process in the Office of Later Examination (OLE).

Having claims with the same or similar scope helps ensure that the later examination can rely on the previous findings, which implies a level of patentability that has already been established. This provision encourages applicants to draft their claims in a way that aligns closely with those examined previously, underpinning the collaborative aim of the PPH initiative and ultimately reducing the time and resources spent on the examination.
