What this shows Joyetech's Innovation Score is 24.4/100 (14th 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 Joyetech?

Each dot is one of Joyetech’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). Joyetech’s own 10.0 claims/patent is at or below the 10.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Joyetech's grants concentrate

Joyetech (CHANGZHOU) Electronics Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 90.9% of grants classified under A24F (Smokers' REQUISITES; Match BOXES; Simulated Smoking Devices). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2015. By volume, Joyetech sits between Jiangxi Kingtron Technology Co., Ltd. and Jeanologia, S. L..

Joyetech's three-year grant acceleration

Joyetech (CHANGZHOU) Electronics Co., Ltd. shows 1 grants in 2022–2024 against only 6 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.
