Company patents
SAINT-GOBAIN CERAMICS & PLASTICS, INC.
SAINT-GOBAIN CERAMICS & PLASTICS INC's patent strategy reveals a surprising shift away from its core materials categories, with significant year-over-year declines in 2025 across Functional Materials (-55.6%), Catalysts & Reactors (-69.2%), and Cement & Ceramics (-70.0%), despite these areas still representing the largest portions of its portfolio (40.6%, 29.7%, and 28.7% respectively). While most categories show a general decline in patenting activity in recent years, the emergence of Layered Products (Laminates, Films) with 3 patents so far in 2026, after two years of no activity, suggests a potential re-evaluation of priorities within its materials focus.
