Company patents

L'Oreal

L 'Oreal, while heavily invested in its core "Pharmaceutical Preparations" (62.0% of portfolio) and "Cosmetics & Personal Care Use" (60.0% of portfolio) categories, shows a surprising emerging focus on "Business Methods & Fintech," which experienced a remarkable 127.3% year-over-year growth in 2024, indicating a strategic expansion beyond traditional product development. Despite this, patent filings across most categories, including the core ones, show a significant decline so far in 2026, with "Pharmaceutical Preparations" down 63.3% and "Cosmetics & Personal Care Use" down 63.6% compared to the previous year.
