PARIS SCIENCES ET LETTRES

PARIS SCIENCES ET LETTRES exhibits a surprisingly broad patent strategy across diverse scientific fields, with its top three categories—Material & Chemical Analysis, Pharmaceutical Preparations, and Genetic & Microbiological Assays—each accounting for 12.3% of its portfolio. While Pharmaceutical Preparations saw a rapid 150.0% growth in 2025, its sharp decline of 80.0% so far in 2026, alongside a 100.0% decline in Therapeutic Activity (Pharma) and Laboratory Apparatus for the same period, suggests a significant shift in focus away from these areas.
