What this shows JNC's Innovation Score is 21.1/100 (8th 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 JNC?

Each dot is one of JNC’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). JNC’s own 8.0 claims/patent is at or below the 15.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where JNC's grants concentrate

JNC Filter Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 80% of grants classified under B01D (Separation). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2018. By volume, JNC sits between JK-Holding GMBH and Joma Kunststofftechnik GMBH.

JNC's three-year grant acceleration

JNC Filter Co., Ltd. shows 1 grants in 2022–2024 against only 3 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.
