What this shows Shanghai's Innovation Score is 51.7/100 (top 11% 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 7.8 claims/patent is at or below the 14.3 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 Institute of Optics And Fine Mechanics, Chinese Academy of Sciences is a focused PatentsView assignee: 34 CPC subclasses with 39% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2023 (10 grants) versus a trough of 2 in 2018. By volume, Shanghai sits between Revision Military S.a.r.L. and THE William M. Yarbrough Foundation.

Shanghai's three-year grant acceleration

Shanghai Institute of Optics And Fine Mechanics, Chinese Academy of Sciences shows 24 grants in 2022–2024 against only 13 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.
