PCT Statistics 2016

The PCT Yearly Review, 2017 edition

The 2017 edition of the PCT Yearly Review summarizes PCT activities and developments in 2016, and contains a comprehensive set of statistics relating to PCT filings (including filings by top countries of origin, by top applicants and by technical field) and the performance of the international patent system in 2016, as well as statistics relating to national phase entries in 2015.

Furthermore, the PCT Yearly Review also includes, for the first time, PCT filing data relating to female inventors.  This follows an earlier global study that was published by WIPO in 2016 relating to PCT applications filed by women (for further information, see PCT Newsletter No. 12/2016, page 7). 

The special theme in the PCT Yearly Review this year is how applicants time their international patent filings.  It analyzes the proportions of applicants who accelerated part of their patenting process by filing a PCT application before the 12‑month limit from the priority date or by entering the national phase before the 30‑month limit.  It also looks at whether the shares of entries initiated before the time limit vary across fields of technology.
The PCT Yearly Review is available in English at:
