Company patents
The Lubrizol Corporation
The Lubrizol Corporation, despite its traditional focus on lubricants, shows a surprising emerging interest in Printed Circuits & Electronic Assemblies, which experienced a remarkable 300.0% year-over-year growth in 2025, reaching 5 patents (5.2% of its portfolio). This contrasts with a significant decline in patenting activity across several other categories so far in 2026, including Functional Materials (LCD, Lubricants) and Polymer Synthesis (Polymerization), both showing a -100.0% YoY change.
