Crowdsourcing Patent Examination with the Patent Prosecution Highway

What You Need to Know

  • Key takeaway #1

    The PPH can be a useful tool for streamlining global prosecution of corresponding patent applications—which in turn can reduce costs and increase the chances of successful prosecution.

The Patent Prosecution Highway (PPH) is a work-share arrangement between the patent offices of different countries. It allows for participating patent offices to share—and thus benefit from—work already performed by other participating patent offices.

In short, when a claim (or claims) of a patent application is allowed in a first patent office, a PPH request may be made to fast-track the examination of a corresponding application in a second patent office based on that allowance. So, for example, when a U.S. patent application is allowed, that allowance can be used to fast-track examination in corresponding foreign applications—or vice versa.

For U.S. applicants, the USPTO also requires that: (1) the claims of the U.S. application correspond in scope to the allowed claims of the foreign application, and (2) substantive examination of the U.S. application has not yet begun. Other countries’ requirements may differ.

Successfully utilizing the PPH can significantly reduce the time it takes for the second patent office to conduct its examination—and it is intended to do just that. While additional benefits may vary from country to country, applications examined under the PPH also generally have higher rates of allowance and suffer less from duplicative examination.

These benefits can streamline global prosecution and reduce overall costs for applicants, particularly in view of the ever growing number of countries participating in PPH programs. Presently, the USPTO has PPH agreements with patent offices of the Europe Union, United Kingdom, China, Japan, Taiwan, Mexico, Israel and several other countries and regions.

DOT Final Rule Narrows Airline Delay and Cancellation Reporting Obligation Under FAA Reauthorization Act of 2024

The U.S. Department of Transportation (DOT) published a final rule amending 14 CFR Part 234 that fundamentally changes how airlines report the causes of flight delays and cancellations. Effective October 19, 2026, the rule implements Section 511(b) of the FAA Reauthorization Act of 2024 by creating a new reporting category, the “Section 511(b) category,” for ten specific events that Congress determined are not attributable to airline control. The rule simultaneously narrows the existing "Air Carrier" reporting category by expressly excluding those same ten events....
