Company patents
Pilkington Group Limited
Pilkington Group Limited's patent strategy reveals a surprising shift away from its core materials categories, with both "Glass & Glass-Ceramics" and "Layered Products (Laminates, Films)" experiencing significant declines in 2025 (down 46.7% and 42.9% respectively), despite still forming the bulk of its portfolio at 41.5% and 38.7%. This suggests a potential re-evaluation of R&D focus, especially given the rapid 100.0% YoY growth in "Coating & Surface Treatment" and "Optical Elements & Systems" so far in 2026, indicating emerging priorities in specialized material enhancements and optical applications.
