Portfolio overview
MITSUBISHI HITACHI POWER SYSTEMS, LTD. has been granted 638 US utility patents between 2015 and 2021, placing MITSUBISHI HITACHI POWER SYSTEMS, LTD. at rank #712 across all assignees tracked by PlainPatent. This portfolio spans 145 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.8 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, MITSUBISHI HITACHI POWER SYSTEMS, LTD. is one of the broader-portfolio assignees in the PatentsView dataset. The composite Innovation Score of 52.6/100 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 139 grants, compared with 499 in the 2015–2019 window — a -72% 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. MITSUBISHI HITACHI POWER SYSTEMS, LTD.'s 8.8 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark MITSUBISHI HITACHI POWER SYSTEMS, LTD. against peers pursuing similar technology classes.
