Portfolio overview

QINGDAO HAIER CO., LTD. has been granted 27 US utility patents between 2020 and 2023, placing QINGDAO HAIER CO., LTD. at rank #11,395 across all assignees tracked by PlainPatent. This portfolio spans 17 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 CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 42.0/100 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 2023, with 27 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. QINGDAO HAIER CO., LTD.'s 10.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 17 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark QINGDAO HAIER CO., LTD. against peers pursuing similar technology classes.
