Portfolio overview

Innospec Limited has been granted 66 US utility patents between 2015 and 2025, placing Innospec Limited at rank #5,212 across all assignees tracked by PlainPatent. This portfolio spans 31 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.1 claims per patent with primary concentration in C10L (FUELS NOT OTHERWISE PROVIDED FOR; NATURAL GAS; SYNTHETIC NATURAL GAS OBTAINED BY PROCESSES NOT COVERED BY SUBCLASSES C10G OR C10K; LIQUIFIED PETROLEUM GAS; USE OF ADDITIVES TO FUELS OR FIRES; FIRE-LIG). As a Foreign Corporation, Innospec Limited is one of the more focused assignees in the PatentsView dataset. By volume, Innospec sits between Hebei Wanda TYRE Co., Ltd. (66 patents, rank #5,208) and Jumio Corporation (66 patents, rank #5,216) - the closest US assignees by grant volume. The composite Innovation Score of 54.2/100 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 41 grants, compared with 25 in the 2015–2019 window, a +64% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign 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. Innospec Limited's 18.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 31 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Innospec Limited against peers pursuing similar technology classes.
