What this shows Shanghai's Innovation Score is 47.8/100 (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 14.8 claims/patent is ABOVE the 9.3 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 Tobacco Group Co., Ltd is a focused PatentsView assignee: 9 CPC subclasses with 40% of grants classified under A24F (Smokers' REQUISITES; Match BOXES; Simulated Smoking Devices). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2015. By volume, Shanghai sits between Shanghai Junshi Biosciences Co., Ltd and Shenzhen CHT Technology Co., Ltd.

Shanghai's three-year grant acceleration

Shanghai Tobacco Group Co., Ltd shows 5 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.
