The dataset used for this landscape contains 1,635 published records filed between 2015 and mid-2026, matched against terms covering sunscreen formulation, emulsion and texture combined with film uniformity, water resistance, sensory feel, emulsifier selection, application amount and rub off. This counts published records rather than granted patents, and because publication lags filing by roughly 18 months, the most recent one or two years understate the true filing volume. Treat the figure as the scope of this specific search, not the entire universe of sunscreen patents.

The ranking behind this landscape covers 100 companies, with the single leading assignee holding 107 records. That leader sits well ahead of fifth place at 54 and tenth at 33, yet the top 5 combined still account for only 24.6% of all 1,635 records in scope. In practice this means a large share of activity comes from assignees outside the ranked leaders altogether, so a freedom-to-operate check should not stop at the largest names.

Filing activity rose from 63 records in 2017 to a peak of 88 in 2021, then declined 50% to 44 by 2024 — that decline is the most recent period that can be treated as reliably complete. Figures for 2025 and 2026 are still filling in under normal publication lag, so it would be premature to call the field currently shrinking; it is more accurate to say the field’s most active filing window has already passed. Anyone benchmarking activity should compare against the 2021 peak rather than the most recent partial year.
