Portfolio overview

Qingdao Haier Co., Ltd. has been granted 27 US utility patents between 2020 and 2023, placing Qingdao Haier Co., Ltd. at #11,398 of 50,000 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. By volume, Qingdao sits between Pretium Packaging, L.l.c. (27 patents, rank #11,391) and Resilience Magnum IP, Llc (27 patents, rank #11,399) - the closest US assignees by grant volume. The composite Innovation Score of 42.0/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Grant cadence records the difference between two grant-year windows. Historical data spans 2020 through 2023, with 27 total grants over that period. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. Qingdao Haier Co., Ltd.'s 10.3 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 17 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
