What this shows Acetk's Innovation Score is 36.7/100 (top 46% 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 Acetk?

Each dot is one of Acetk’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). Acetk’s own 2.2 claims/patent is at or below the 16.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Acetk's grants concentrate

Acetk Corp Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 66.7% of grants classified under H05B (Electric HEATING; Electric Light Sources NOT Otherwise Provided FOR; Circuit Arrangements FOR Electric Light Sources, IN General). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2022. By volume, Acetk sits between Acavallo S.R.L. and Activated Research Company, LLC.

Acetk's three-year grant acceleration

Acetk Corp Ltd. shows 4 grants in 2022–2024 against only 0 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.
