USPTO Announces More PPH Agreements, China and Iceland
The USPTO always also points out that PPH agreements increase patent quality. That is likely true, but probably not as directly as you might expect. As far as I can tell the benefit to quality comes as the result of primarily three things. First, it takes less time to examine a patent application that has arrived to the Office of Second Filing (OSF) because allowable matter has already been identified somewhere else, which substantially focuses the prosecution of these applications. Second, by requiring less time on some applications there will be more time for other applications, at least in theory. Finally, there is no doubt a self-selection that goes on from the applicants side, which means better patent applications, and the overwhelming number of those using the PPH accept the claims they get and do not circle back for more claims, or broader claims, with supplemental filings.
