What this shows JDC's Innovation Score is 48.3/100 (top 17% 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 JDC?

Each dot is one of JDC’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). JDC’s own 13.7 claims/patent is at or below the 14.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where JDC's grants concentrate

JDC Corporation is a focused PatentsView assignee: 30 CPC subclasses with 40% of grants classified under B65H (Handling Thin OR Filamentary Material, e.g. Sheets, Webs, Cables). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2015. By volume, JDC sits between Japan Communication Accessories Manufacturing Co., Ltd. and Jonker LLC.

JDC's three-year grant acceleration

JDC Corporation shows 5 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.
