What this shows Haier's Innovation Score is 70.6/100 (top 1% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Haier?

Each dot is one of Haier’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Haier’s own 10.5 claims/patent is at or below the 12.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Haier's grant cadence moved

Grant history spans 2021–2025. Across complete PatentsView years, output peaked in 2024 at 112 grants and bottomed in 2021 at 14. Lead class F25D accounts for 44.8% of the portfolio across 80 subclasses. Volume neighbours: Resonac Corporation (#1,537) and Endress+Hauser SE+Co. KG (#1,545).

Haier's three-year grant acceleration

Haier Smart Home Co., Ltd. shows 199 grants in 2022–2024 against only 14 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
