Company patents

Merck Patent GmbH

Merck Patent GmbH's patent strategy reveals a surprising shift away from its historically strong Functional Materials (LCD, Lubricants) category, which constitutes 35.8% of its portfolio but saw a significant 23.2% decline in 2025 and a further 46.6% drop so far in 2026. While core pharma categories like Heterocyclic Compounds (Pharma) and Pharmaceutical Preparations remain substantial, the company showed an emerging focus in 2024 with rapid growth in Coating Compositions (Paints, Inks) at +163.6% YoY and Photolithography at +100.0% YoY, suggesting diversification into materials and semiconductor manufacturing, although patenting in these areas has also seen a decline so far in 2026.
