Company patents
Kemira OYJ
KEMIRA OYJ's patent strategy reveals a strong, sustained focus on "Water / Sewage Treatment," which constitutes 20.5% of its portfolio and saw an 83.3% YoY growth in 2024, indicating a continued commitment to this core area despite a partial year decline so far in 2026. Surprisingly, while "Polymer Compositions" and "Polymer Synthesis (Polymerization)" represent significant portions of their portfolio (11.9% and 11.3% respectively), both have experienced consistent declines in patenting activity over the past two years, suggesting a potential shift in R&D priorities away from these polymer-centric areas.
