What this shows JEN's Innovation Score is 38.3/100 (top 41% 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 JEN?

Each dot is one of JEN’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). JEN’s own 6.2 claims/patent is at or below the 10.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where JEN's grants concentrate

JEN Sian Industrial Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 16.7% of grants classified under F17C (Vessels FOR Containing OR Storing Compressed, Liquefied OR Solidified GASES; Fixed-capacity GAS-HOLDERS; Filling Vessels With, OR Discharging From Vessels, Compressed, Liquefied, OR Solidified Gases). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2015. By volume, JEN sits between JC Korea Corp. and JGC Japan Corporation.

JEN's three-year grant acceleration

JEN Sian Industrial 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.
