PCT Patent Prosecution Highway (PCT‑PPH) Pilots

New one‑way PCT‑PPH pilot program (Argentina and the United States of America)

On 3 June 2019, a new one‑way PCT‑PPH pilot program will start between the National Institute of Industrial Property (INPI) (Argentina)1 and the United States Patent and Trademark Office (USPTO).  Under this program, accelerated processing of a national (Paris route) filing before INPI is available on the basis of a PCT application with a positive written opinion from either the International Searching Authority (ISA) or the International Preliminary Examining Authority (IPEA), or a positive international preliminary report on patentability (IPRP) (Chapter II), issued by the USPTO in its capacity as ISA/IPEA.  The program is also available on the basis of national work products.

Further information on the above-mentioned PCT‑PPH agreement is available at:


The PCT‑PPH page of the PCT website has been updated to include information on this new pilot (www.wipo.int/pct/en/filing/pct_pph.html).
