What this shows AHA's Innovation Score is 40.6/100 (top 35% 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 AHA?

Each dot is one of AHA’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). AHA’s own 28.2 claims/patent is ABOVE the 14.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where AHA's grants concentrate

AHA Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 33.3% of grants classified under F24C (Domestic Stoves OR Ranges ; Details OF Domestic Stoves OR Ranges, OF General Application). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2015. By volume, AHA sits between AGR Subsea, A.S. and Aidance Skincare & Topical Solutions LLC.

AHA's three-year grant acceleration

AHA Co., Ltd. shows 2 grants in 2022–2024 against only 2 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.
