Does more volume mean deeper claims for Jiangsu?

Each dot is one of Jiangsu’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). Jiangsu’s own 12.2 claims/patent is ABOVE the 11.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Jiangsu's grants concentrate

Jiangsu Changjiang Electronics Technology Co., Ltd. is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2015 (3 grants) versus a trough of 1 in 2020. By volume, Jiangsu sits between JAE Electronics, Inc. and Jilin Asymchem Laboratories Co., Ltd..

Jiangsu's three-year grant acceleration

Jiangsu Changjiang Electronics Technology Co., Ltd. shows 3 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.
