What this shows Shanghai's Innovation Score is 51.2/100 (top 12% 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 Shanghai?

Each dot is one of Shanghai’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). Shanghai’s own 14.4 claims/patent is ABOVE the 13.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Shanghai's grants concentrate

Shanghai Huali Integrated Circuit Mfg. Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 78.6% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2022 (10 grants) versus a trough of 1 in 2023. By volume, Shanghai sits between Seismos, Inc. and Shaper Tools, Inc..

Shanghai's three-year grant acceleration

Shanghai Huali Integrated Circuit Mfg. Co., Ltd. shows 11 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.
