What this shows Shanghai's Innovation Score is 25.6/100 (18th 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 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 9.4 claims/patent is at or below the 14.0 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 Air-paq Composite Material Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 100% of grants classified under B65D (Containers FOR Storage OR Transport OF Articles OR Materials, e.g. Bags, Barrels, Bottles, Boxes, Cans, Cartons, Crates, Drums, Jars, Tanks, Hoppers, Forwarding CONTAINERS; Accessories, Closures, OR F). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2017. By volume, Shanghai sits between Serralux Inc. and Shanghai Nuclear Engineering Research & Design Institute Co., Ltd..

Shanghai's three-year grant acceleration

Shanghai Air-paq Composite Material 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.
