The scale of the challenge is growing: according to WIPO’s World Intellectual Property Indicators (2025), global patent applications climbed 4.9% to 3.7 million in 2024, the fastest year-on-year growth since 2018, meaning more businesses than ever are navigating multi-jurisdiction filing requirements.
