Portfolio overview

The Lubrizol Corporation has been granted 262 US utility patents between 2015 and 2025, placing The Lubrizol Corporation at rank #1,582 across all assignees tracked by PlainPatent. This portfolio spans 45 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.5 claims per patent with primary concentration in C10N (INDEXING SCHEME ASSOCIATED WITH SUBCLASS C10M RELATING TO LUBRICATING COMPOSITIONS). As a US Corporation, The Lubrizol Corporation is one of the more focused assignees in the PatentsView dataset. By volume, The sits between Kabushiki Kaisha Toyota CHUO Kenkyusho (262 patents, rank #1,578) and Kyushu University, National University Corporation (261 patents, rank #1,586) - the closest US assignees by grant volume. The composite Innovation Score of 55.4/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 100 grants, compared with 162 in the 2015–2019 window, a -38% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. The Lubrizol Corporation's 14.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 45 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark The Lubrizol Corporation against peers pursuing similar technology classes.
