Portfolio overview

HINDUSTAN PETROLEUM CORPORATION LIMITED has been granted 54 US utility patents between 2017 and 2025, placing HINDUSTAN PETROLEUM CORPORATION LIMITED at rank #6,243 across all assignees tracked by PlainPatent. This portfolio spans 27 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.2 claims per patent with primary concentration in B01J (CHEMICAL OR PHYSICAL PROCESSES, e.g. CATALYSIS OR COLLOID CHEMISTRY; THEIR RELEVANT APPARATUS). As a Foreign Corporation, HINDUSTAN PETROLEUM CORPORATION LIMITED is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 43.4/100 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 42 grants, compared with 12 in the 2015–2019 window — a +250% 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. HINDUSTAN PETROLEUM CORPORATION LIMITED's 12.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 27 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark HINDUSTAN PETROLEUM CORPORATION LIMITED against peers pursuing similar technology classes.
