Company patents
BEIJING HUAMEI, INC.
BEIJING HUAMEI INC. demonstrates a surprising dual focus, with 60.8% of its portfolio in Drilling & Mining and 54.6% in Functional Materials (LCD, Lubricants), both experiencing rapid growth in 2024 (Drilling & Mining at +144.4% YoY and Functional Materials at +162.5% YoY). However, the company appears to be shifting away from several Polymer-related categories, with Polymer Additives, Polymer Compositions, Polymer Synthesis (Polymerization), and Polymer Synthesis (Polycondensation) all showing significant declines or zero patents so far in 2026.
