What this shows Sogang's Innovation Score is 58.6/100 (top 4% 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 Sogang?

Each dot is one of Sogang’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). Sogang’s own 13.0 claims/patent is ABOVE the 10.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

How Sogang's grant cadence moved

Between 2020–2024, Sogang University Research & Business Development Foundation received 28 grants versus 2 in 2015–2019 (+1300% equal-window velocity, top decile growth). Across complete PatentsView years, output peaked in 2024 at 8 grants and bottomed in 2019 at 2. Lead class Y02E accounts for 16.7% of the portfolio across 50 subclasses. Volume neighbours: Senju Sprinkler Co., Ltd. (#8,914) and Security People, Inc. (#8,922).

Sogang's three-year grant acceleration

Sogang University Research & Business Development Foundation shows 20 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.
