Portfolio overview

Mitsubishi Electric Corporation has been granted 15,053 US utility patents between 2015 and 2025, placing Mitsubishi Electric Corporation at rank #19 across all assignees tracked by PlainPatent. This portfolio spans 439 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.1 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, Mitsubishi Electric Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Mitsubishi sits between Ford Global Technologies, Llc (18,527 patents, rank #15) and Panasonic Intellectual Property Management Co., Ltd. (13,148 patents, rank #23) - the closest US assignees by grant volume. The composite Innovation Score of 70.1/100 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 7,817 grants, compared with 7,236 in the 2015–2019 window, a +8% 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. Mitsubishi Electric Corporation's 10.1 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 Electric Corporation 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.
