Rising regions of the patent landscape

Where patent filings are expected to grow fastest by 2027, field by field — forecast from 76 million patent families, before the classifications name the trend.

Each region is a cluster of about 2,300 patent families with closely related content, named from its titles. ×2.0 = twice as many priority filings expected in 2027 as in 2024. Blue: filings 2015-2024, corrected for the publication delay (up to 18 months); amber dashed: 2025 estimated from what is already published, then the forecast 2026-2028. After a surge the model expects growth to slow down — the statistically safest bet over fifty years of filings. Knowledge: EPO DOCDB publications up to August 2026 · updated 2026-10-23.
