How many triadic patents were applied for by Dutch authorities in the period 2002-2022? A triadic patent is a patent applied for at the patent offices of Europe (European Patent Office), the US (United States Patent and Trademark Office) and Japan (Japan Patent Office). In this data publication we share the figures of the number of triadic patents, per year.

In short

  • The number of Dutch triadic patents has grown significantly in 2022.
  • In 2022, Japan and the US filed the most triadic patents.
  • Internationally compared, the Netherlands is above the median of the reference countries shown here.

Notes: A triadic patent request has been filed at the patent offices in Europe (EPO), USA (USPTO) and Japan (JPO). Figures for the three most recent priority years concern provisional estimates.

Analysis
From 2003, the number of triadic patents applications from the Netherlands decreased up to 2011. From 2011 the annual number of triadic patent requests increases until 2015. After a short period of decline, the number rises again from 2019 onwards. The majority of the applications are from the industrial sector (CBS, 2023).

Notes: A triadic patent family implies that the patent request has been filed at the patent offices in Europe (EPO), USA (USPTO) and Japan (JPO). Due to the relatively large numbers, data for triadic patent requests filed by inventors from Japan (16.425) and the USA (15.193) have been excluded from the graph below.

Analysis
The number of triadic patent requests filed by inventors from the Netherlands in 2022 surpasses the number of requests filed by a majority of countries in the benchmark.
