What this shows Sungkyunkwan's Innovation Score is 38.3/100 (top 41% 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 Sungkyunkwan?

Each dot is one of Sungkyunkwan’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). Sungkyunkwan’s own 13.3 claims/patent is at or below the 16.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sungkyunkwan's grants concentrate

Sungkyunkwan University Research & Business Foundation is a focused PatentsView assignee: 26 CPC subclasses with 47.4% of grants classified under H04L (Transmission OF Digital Information, e.g. Telegraphic Communication). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2021. By volume, Sungkyunkwan sits between Stout Stuff, LLC and Sys-Tech Solutions, Inc..

Sungkyunkwan's three-year grant acceleration

Sungkyunkwan University Research & Business Foundation shows 2 grants in 2022–2024 against only 7 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.
