Portfolio overview

QINGDAO HAIER JOINT STOCK CO., LTD. has been granted 84 US utility patents between 2018 and 2024, placing QINGDAO HAIER JOINT STOCK CO., LTD. at rank #4,256 across all assignees tracked by PlainPatent. This portfolio spans 31 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.4 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 JOINT STOCK CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 43.9/100 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 73 grants, compared with 11 in the 2015–2019 window — a +564% 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 JOINT STOCK CO., LTD.'s 11.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 31 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark QINGDAO HAIER JOINT STOCK CO., LTD. against peers pursuing similar technology classes.
