Portfolio overview

SASOL TECHNOLOGY PROPRIETARY LIMITED has been granted 41 US utility patents between 2015 and 2022, placing SASOL TECHNOLOGY PROPRIETARY LIMITED at rank #7,919 across all assignees tracked by PlainPatent. This portfolio spans 22 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.2 claims per patent with primary concentration in C10G (CRACKING HYDROCARBON OILS; PRODUCTION OF LIQUID HYDROCARBON MIXTURES, e.g. BY DESTRUCTIVE HYDROGENATION, OLIGOMERISATION, POLYMERISATION ; RECOVERY OF HYDROCARBON OILS FROM OIL-SHALE, OIL-SAND, OR GAS). As a Foreign Corporation, SASOL TECHNOLOGY PROPRIETARY LIMITED is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 38.3/100 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 1 grants, compared with 40 in the 2015–2019 window — a -97% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. SASOL TECHNOLOGY PROPRIETARY LIMITED's 13.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 22 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SASOL TECHNOLOGY PROPRIETARY LIMITED against peers pursuing similar technology classes.
