What this shows Hefei's Innovation Score is 63.6/100 (top 2% 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 Hefei?

Each dot is one of Hefei’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). Hefei’s own 10.9 claims/patent is at or below the 11.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Hefei's grant cadence moved

Between 2020–2024, Hefei Institutes of Physical Sciences, Chinese Academy of Sciences received 36 grants versus 3 in 2015–2019 (+1100% equal-window velocity, top decile growth). Across complete PatentsView years, output peaked in 2024 at 14 grants and bottomed in 2017 at 1. Lead class Y02E accounts for 21.3% of the portfolio across 51 subclasses. Volume neighbours: Government of the United States, as represented by the Secretary of the Air Force (#7,011) and Inari Agriculture Technology, Inc. (#7,019).

Hefei's three-year grant acceleration

Hefei Institutes of Physical Sciences, Chinese Academy of Sciences shows 28 grants in 2022–2024 against only 10 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.
