Portfolio overview
QINGDAO HAIER AIR-CONDITIONING ELECTRONIC CO., LTD. has been granted 36 US utility patents between 2021 and 2025, placing QINGDAO HAIER AIR-CONDITIONING ELECTRONIC CO., LTD. at rank #8,897 across all assignees tracked by PlainPatent. This portfolio spans 16 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.9 claims per patent with primary concentration in F24F (AIR-CONDITIONING; AIR-HUMIDIFICATION; VENTILATION; USE OF AIR CURRENTS FOR SCREENING). As a Foreign Corporation, QINGDAO HAIER AIR-CONDITIONING ELECTRONIC CO., LTD. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 51.9/100 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. Historical data spans 2021 through 2025, with 36 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 AIR-CONDITIONING ELECTRONIC CO., LTD.'s 8.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 16 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark QINGDAO HAIER AIR-CONDITIONING ELECTRONIC CO., LTD. against peers pursuing similar technology classes.
