Portfolio overview

Qingdao Haier Smart Technology R&D Co., Ltd. has been granted 40 US utility patents between 2019 and 2024, placing Qingdao Haier Smart Technology R&D Co., Ltd. at rank #8,099 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.3 claims per patent with primary concentration in D06F (LAUNDERING, DRYING, IRONING, PRESSING OR FOLDING TEXTILE ARTICLES). As a Foreign Corporation, Qingdao Haier Smart Technology R&D Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Qingdao sits between Powertech Industrial Co., Ltd. (40 patents, rank #8,095) and RPC Bramlage Gmbh (40 patents, rank #8,103) - the closest US assignees by grant volume. The composite Innovation Score of 37.1/100 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 34 grants, compared with 6 in the 2015–2019 window, a +467% 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 Smart Technology R&D Co., Ltd.'s 13.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Qingdao Haier Smart Technology R&D Co., Ltd. against peers pursuing similar technology classes.
