Portfolio overview
QINGDAO HAIER REFRIGERATOR CO., LTD. has been granted 98 US utility patents between 2018 and 2025, placing QINGDAO HAIER REFRIGERATOR CO., LTD. at rank #3,712 across all assignees tracked by PlainPatent. This portfolio spans 45 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.3 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, QINGDAO HAIER REFRIGERATOR CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 65.8/100 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 97 grants, compared with 1 in the 2015–2019 window — a +9600% 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. QINGDAO HAIER REFRIGERATOR CO., LTD.'s 10.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 45 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark QINGDAO HAIER REFRIGERATOR CO., LTD. against peers pursuing similar technology classes.
