Portfolio overview

Mitsubishi Power, Ltd. has been granted 222 US utility patents between 2020 and 2025, placing Mitsubishi Power, Ltd. at rank #1,824 across all assignees tracked by PlainPatent. This portfolio spans 106 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.2 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 Power, Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Mitsubishi sits between Gentherm Incorporated (223 patents, rank #1,820) and Brose Fahrzeugteile Gmbh & Co. Kommanditgesellschaft (221 patents, rank #1,828) - the closest US assignees by grant volume. The composite Innovation Score of 54.2/100 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. Historical data spans 2020 through 2025, with 222 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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 Power, Ltd.'s 10.2 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 Power, Ltd. against peers pursuing similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
