Portfolio overview

Hefei Midea Refrigerator Co., Ltd. has been granted 71 US utility patents between 2015 and 2025, placing Hefei Midea Refrigerator Co., Ltd. at rank #4,883 across all assignees tracked by PlainPatent. This portfolio spans 40 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.0 claims per patent with primary concentration in F25D (REFRIGERATORS; COLD ROOMS; ICE-BOXES; COOLING OR FREEZING APPARATUS NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, Hefei Midea Refrigerator Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Hefei sits between Fujitsu Technology Solutions Intellectual Property Gmbh (71 patents, rank #4,879) and International Rectifier Corporation (71 patents, rank #4,887) - the closest US assignees by grant volume. The composite Innovation Score of 55.8/100 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 52 grants, compared with 19 in the 2015–2019 window, a +174% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Hefei Midea Refrigerator Co., Ltd.'s 12.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 40 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hefei Midea Refrigerator Co., Ltd. against peers pursuing similar technology classes.
