What this shows Nankai's Innovation Score is 55.5/100 (top 7% 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 Nankai?

Each dot is one of Nankai’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). Nankai’s own 8.4 claims/patent is at or below the 16.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

How Nankai's grant cadence moved

Between 2020–2024, Nankai University received 27 grants versus 9 in 2015–2019 (+200% equal-window velocity, above median growth). Across complete PatentsView years, output peaked in 2023 at 9 grants and bottomed in 2016 at 1. Lead class C07D accounts for 21.3% of the portfolio across 59 subclasses. Volume neighbours: Microchip Technology Germany GmbH (#7,048) and Ospedale SAN Raffaele S.R.L. (#7,056).

Nankai's three-year grant acceleration

Nankai University shows 20 grants in 2022–2024 against only 11 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.
