What this shows PAN's Innovation Score is 27.9/100 (25th 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 PAN?

Each dot is one of PAN’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). PAN’s own 9.1 claims/patent is at or below the 11.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where PAN's grants concentrate

PAN Pacific Copper Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 55.6% of grants classified under F27D (Details OR Accessories OF Furnaces, Kilns, Ovens OR Retorts, IN SO FAR AS They ARE OF Kinds Occurring IN More Than ONE Kind OF Furnace). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2018. By volume, PAN sits between P-duke Technology Co., Ltd. and Parkson Corporation.

PAN's three-year grant acceleration

PAN Pacific Copper 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.
