Company patents
Sanofi
Sanofi's patent strategy surprisingly leans heavily into medical devices, with 'Drug Delivery Devices' making up 52.1% of its portfolio, significantly more than any pharma-biotech category. While most categories saw strong growth in 2024, the sharp declines across the board so far in 2026, including a -74.6% drop in 'Drug Delivery Devices' and a -100.0% drop in 'Machine Learning & AI', suggest a potential re-evaluation or shift in patenting focus.
