What this shows Jeco's Innovation Score is 26.3/100 (20th 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 Jeco?

Each dot is one of Jeco’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). Jeco’s own 6.6 claims/patent is at or below the 12.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Jeco's grants concentrate

Jeco Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 60% of grants classified under F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; Devices FOR Venting OR Aerating). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2019. By volume, Jeco sits between Janssen Diagnostics, LLC and Jenrin Discovery, LLC.

Jeco's three-year grant acceleration

Jeco Co., Ltd. shows 2 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.
