Company patents
CALB Co., Ltd.
CALB Co. Ltd. surprisingly shows a significant decline in patenting within its core "Batteries & Fuel Cells" category, dropping by 63.4% in 2025 and remaining flat so far in 2026, despite this area still representing 93.7% of its total portfolio. This shift suggests a potential re-evaluation of its R&D focus, especially given the complete cessation of patenting in "Electrical Measurement" (YoY -100.0% in 2026) and "Electric Vehicle Propulsion" (YoY -100.0% in 2025 and 2026) after prior growth.
