What this shows Ingamar's Innovation Score is 25.3/100 (17th percentile 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 Ingamar?

Each dot is one of Ingamar’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). Ingamar’s own 10.6 claims/patent is at or below the 13.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Ingamar's grants concentrate

Ingamar Co., Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 80% of grants classified under E05B (LOCKS; Accessories THEREFOR; Handcuffs). By volume, Ingamar sits between Inergy Holdings, LLC and Inlc Technology Co., Ltd.,.

Ingamar's three-year grant acceleration

Ingamar Co., Ltd. shows 1 grants in 2022–2024 against only 1 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.
