What this shows Guangzhou's Innovation Score is 56.2/100 (top 6% 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 Guangzhou?

Each dot is one of Guangzhou’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). Guangzhou’s own 8.8 claims/patent is at or below the 14.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Guangzhou's grant cadence moved

Between 2020–2024, Guangzhou Institute OF Energy Conversion, Chinese Academy OF Sciences received 30 grants versus 17 in 2015–2019 (+76% equal-window velocity, above median growth). Across complete PatentsView years, output peaked in 2024 at 11 grants and bottomed in 2015 at 1. Lead class E21B accounts for 42% of the portfolio across 62 subclasses. Volume neighbours: Ferroelectric Memory GmbH (#6,650) and Guidewire Software, Inc. (#6,658).

Guangzhou's three-year grant acceleration

Guangzhou Institute OF Energy Conversion, 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.
