USPTO PatentsView assignee record - 11 granted patents across 5 technology areas, active 2022–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: D06F (LAUNDERING, DRYING, IRONING, PRESSING OR FOLDING TEXTILE ARTICLES).
The verdict
Qingdao holds 11 US patents across 5 technology areas, rank #25,030 of 50,000 tracked assignees.
Qingdao Haier Laundry Electric Appliances Co., Ltd has been granted 11 US utility patents between 2022 and 2025, placing Qingdao Haier Laundry Electric Appliances Co., Ltd at rank #25,030 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.6 claims per patent with primary concentration in D06F (LAUNDERING, DRYING, IRONING, PRESSING OR FOLDING TEXTILE ARTICLES). As a Foreign Corporation, Qingdao Haier Laundry Electric Appliances Co., Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Qingdao sits between Pvolve, Llc (11 patents, rank #25,026) and Qualcomm Connected Experiences, Inc. (11 patents, rank #25,034) - the closest US assignees by grant volume. The composite Innovation Score of 44.6/100 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 2022 through 2025, with 11 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 Laundry Electric Appliances Co., Ltd's 13.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Qingdao Haier Laundry Electric Appliances Co., Ltd against peers pursuing similar technology classes.

How to use this portfolio
Qingdao's 11 grants land it in the top 25% by Innovation Score, but volume alone doesn't tell you where the strength sits.
Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
