2. Global PPH and IP5 PPH
• Prevents multiple countries from duplicating the same
work
• PPH request may be filed in the USPTO based on the
work product of any office participating in either pilot
program
– Positive result from PCT or national work product
• Single request form
• Permits accelerated processing for FREE
• https://www.wipo.int/pct/en/filing/pct_pph.html

6. Eligibility for PPH
• U.S. application must have the same earliest filing date
or priority date as the one in the other Patent
Prosecution Highway office
• Application must have at least one claim that a
participating office has ruled is patentable or allowable
• All claims to the USPTO must tie back to the claim in a
foreign office (almost identical or narrower)
• USPTO cannot have started a review of the patent prior
to the PPH request

10. Once applied…
• USPTO tells the applicant that they’re accepted or
denied
– If accepted, the applicant advances ahead of other patent
applicants in line
– If denied, the applicant gets one chance to discuss the
defects in the patent and reply with a perfected request

11. EPO PPH Quirks
• Table showing how each claim of the 2nd application
corresponds to an allowed claim of the 1st application
• EPO will still conduct its own search and examination,
and will independently consider whether the
application meets EPC patentability requirements
• Offers own accelerated examination – PACE
– Less onerous than PPH
– More flexible for claims that can be presented
– Request not placed in public file
• UKIPO views PPH more favorably than EPO

12. Results in Different Countries
• Higher Grant Rate
– 92% PPH grant vs. 71% overall – SIPO
– 100% PPH grant vs. 52% overall – IP Australia
• Faster Disposition
– 2.6-2.8 months vs. 9.4 months – JPO
– 2.5-2.9 months vs. 10.8 months - KIPO

13. Caveats
• Examiner in one country may raise objections and make
adverse comments on claims allowed elsewhere
• Each participating office has own “support,” “clarity,”
and “enablement” criteria
• PPH request preparation + prosecution – may not be
much less than non-PPH examination
