What this shows Acculab's Innovation Score is 31.1/100 (36th 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 Acculab?

Each dot is one of Acculab’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). Acculab’s own 17.2 claims/patent is ABOVE the 11.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Acculab's grants concentrate

Acculab Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 60% of grants classified under C09K (Materials FOR Miscellaneous Applications, NOT Provided FOR Elsewhere). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2022. By volume, Acculab sits between ABrite Tech Shanghai Co., Ltd. and Acesion Pharma APS.

Acculab's three-year grant acceleration

Acculab 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.
