What this shows PJ's Innovation Score is 39.3/100 (top 38% 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 PJ?

Each dot is one of PJ’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). PJ’s own 9.2 claims/patent is at or below the 15.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where PJ's grants concentrate

PJ Factory Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 83.3% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2018. By volume, PJ sits between Pineapple Contracts Unlimited and Plantics B.V..

PJ's three-year grant acceleration

PJ Factory Co., Ltd. shows 4 grants in 2022–2024 against only 1 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.
