Portfolio overview

Haier Smart HOME Co., Ltd. has been granted 270 US utility patents between 2021 and 2025, placing Haier Smart HOME Co., Ltd. at rank #1,541 across all assignees tracked by PlainPatent. This portfolio spans 80 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.5 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, Haier Smart HOME Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Haier sits between Resonac Corporation (271 patents, rank #1,537) and Endress+hauser Se+co. KG (269 patents, rank #1,545) - the closest US assignees by grant volume. The composite Innovation Score of 70.6/100 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 2021 through 2025, with 270 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. Haier Smart HOME Co., Ltd.'s 10.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 80 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Haier Smart HOME Co., Ltd. against peers pursuing similar technology classes.

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.
