GENEVA - Demand for patent protection continued to grow in 2022, with innovators in China, the United States, Japan, the Republic of Korea and Germany leading in filings under WIPO’s Patent Cooperation Treaty (PCT) which simplifies the process of seeking patent protection in multiple countries, a press release stated by the World Intellectual Property Organization (WIPO).

In 2022, PCT filings rose slightly by 0.3%, totaling 278,100 - the highest number ever recorded in a single year. India (+25.4%) and the Republic of Korea (+6.2%) saw sharp growth in PCT filings.

The overall modest growth rate reflects the challenging economic conditions prevailing in 2022.  Notwithstanding these conditions, firms continued to invest in innovation and intellectual property.  

Asia remained the dominant source of international patent applications, accounting for 54.7% of the 2022 total, up from 40.3% in 2012.

Demand for design protection saw double-digit growth, with China's 2022 accession to WIPO's international design registration system fueling a surge in international design applications.

In 2022, the number of designs included in international applications under WIPO’s Hague System for the International Registration of Industrial Designs  increased by 11.2% to reach 25,028.

Following exceptional growth of 15% in 2021, use of the international trademark system for brand protection in 2022 declined by -6.1%, the largest drop since 2009. The total number of applications filed in 2022 was about 69,000.

The economic disruptions caused by the COVID-19 pandemic in 2021 prompted firms to introduce new goods and services which helped fuel the exceptional growth in international trademark protection. Although lower than in 2021, the total number of applications filed under WIPO’s Madrid System for the International Registration of Trademarks in 2022 was still 8% higher than in 2020.

"International IP filings largely held up in 2022. Despite difficult economic conditions and a decline in risk finance, businesses continued to invest in innovation. China’s entry into the Hague System – WIPO’s international register for industrial designs – fueled design applications from China and the rest of the world, showing that multilateral approaches to international cooperation can deliver benefits for everyone." WIPO Director General Daren Tang said.

After the particularly strong growth in health-related technology fields of last year, digital technology fields returned to the fastest growing fields among PCT applications in 2022.

International trademark system (Madrid System)

Top Madrid filers

The total number of applications filed under the Madrid System in 2022 reached 69,000. US-based applicants (12,495) filed the largest number of international trademark applications, followed by those located in Germany (7,695), China (4,991), France (4,403) and the United Kingdom (4,227).

Among the top 15 countries of origin, only three – the Netherlands (+7.4%), the Republic of Korea (+2.1%) and Türkiye (+5.2%) – recorded growth from 2021 to 2022. In contrast, Germany (–12.5%) and Italy (–13.9%) saw the sharpest declines. Despite the one-year decreases for top origins France (–10.0%), the UK (–0.9%) and the US (–5.9%) from 2021 to 2022, their 2022 application numbers were still higher than their 2020 levels by 17.7%, 12.9% and 24.8%, respectively.

L’Oréal of France, with 160 Madrid applications, remained the top filer for the second year running in 2022. Novartis AG (131) of Switzerland moved up three places to become the second top filer, followed by Glaxo Group of the UK (128), Bulgaria’s Euro Games Technology (120) and Hyundai Motor Company (108) of the Republic of Korea. Hyundai Motor Company filed 77 more applications in 2022 than in 2021, elevating it from 48th position to the 5th largest applicant. Active in online grocery delivery and pick-up, Maplebear Inc.
