Portfolio overview

Intelligent Energy Limited has been granted 219 US utility patents between 2015 and 2025, placing Intelligent Energy Limited at rank #1,840 across all assignees tracked by PlainPatent. This portfolio spans 55 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.9 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a Foreign Corporation, Intelligent Energy Limited is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Intelligent sits between Hosiden Corporation (220 patents, rank #1,836) and Vista Outdoor Operations Llc (219 patents, rank #1,844) - the closest US assignees by grant volume. The composite Innovation Score of 55.6/100 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 46 grants, compared with 173 in the 2015–2019 window, a -73% 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. Intelligent Energy Limited's 14.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 55 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Intelligent Energy Limited against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
