What this shows Jiahua's Innovation Score is 45.0/100 (top 24% 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 Jiahua?

Each dot is one of Jiahua’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). Jiahua’s own 12.8 claims/patent is ABOVE the 6.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Jiahua's grants concentrate

Jiahua Science & Technology Development (Shanghai) Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 60% of grants classified under C08J (WORKING-UP; General Processes OF COMPOUNDING; After-treatment NOT Covered BY Subclasses C08b, C08c, C08f, C08g or C08h). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2023. By volume, Jiahua sits between Jenny Yoo Collection, Inc. and Jiangsu Yahong Meditech Co., Ltd..

Jiahua's three-year grant acceleration

Jiahua Science & Technology Development (Shanghai) Ltd. shows 5 grants in 2022–2024 against only 0 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.
