Portfolio overview
IHI Charging Systems International GmbH has been granted 33 US utility patents between 2015 and 2024, placing IHI Charging Systems International GmbH at rank #9,523 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.7 claims per patent with primary concentration in F05D (INDEXING SCHEME FOR ASPECTS RELATING TO NON-POSITIVE-DISPLACEMENT MACHINES OR ENGINES, GAS-TURBINES OR JET-PROPULSION PLANTS). As a Foreign Corporation, IHI Charging Systems International GmbH is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 33.5/100 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 17 grants, compared with 16 in the 2015–2019 window, a +6% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. IHI Charging Systems International GmbH's 8.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark IHI Charging Systems International GmbH against peers pursuing similar technology classes.
