What this shows Shanghai's Innovation Score is 47.9/100 (top 18% 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 17.7 claims/patent is at or below the 18.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Shanghai's grants concentrate

Shanghai Yingli Pharmaceutical Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under C07D (Heterocyclic Compounds). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2016. By volume, Shanghai sits between Senscomm Semiconductor Co., Ltd. and Shazam Investments Ltd..

Shanghai's three-year grant acceleration

Shanghai Yingli Pharmaceutical 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.
