PCT Filings in 2018
In 2018, use of the PCT continued to grow, with a record‑breaking quarter of a million PCT applications filed. The estimated 253,0001 applications represents a 3.9% increase over 2017. For the first time, Asia‑based applicants filed more than half (50.5%) of all PCT applications, helped by significant growth from China, the Republic of Korea and India. Applicants from Europe filed 24.5% of all applications, and those from North America filed 23.1%.
Applicants based in the United States of America (U.S.) maintained their number one ranking, with 56,142 applications filed, accounting for 22.2% of the total filed in 2018. The U.S. was followed very closely by China (53,345 applications), ranking second for the second year running with 21.1% of all filings. As was the case in 2017, the third, fourth and fifth rankings were held by Japan (49,702), Germany (19,883) and the Republic of Korea (17,014).
The total for each country in the top 10, followed by that country’s percentage share of all filings, were as follows:
|1.||United States of America||56,142||22.2%|
|5.||Republic of Korea||17,014||6.7%|
Among the top 15 origins, India (+27.2%) and Finland (+14.7%) were the only two countries to record double-digit annual growth in 2018. China (+9.1%) and the Republic of Korea (+8%) both saw strong growth, although China’s rate was its lowest since 2002. The United Kingdom recorded a 1.3% increase in filings, representing five uninterrupted years of growth. In contrast, the Netherlands (-6.6%), France (-1.2%) and the U.S. (-0.9%) each saw a decrease in filings.
