What this shows Changwon's Innovation Score is 31.7/100 (39th percentile 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 Changwon?

Each dot is one of Changwon’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). Changwon’s own 7.3 claims/patent is at or below the 15.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Changwon's grants concentrate

Changwon National University Industry Academy Cooperation Corps is a focused PatentsView assignee: 25 CPC subclasses with 30% of grants classified under B23K (Soldering OR UNSOLDERING; WELDING; Cladding OR Plating BY Soldering OR WELDING; Cutting BY Applying Heat Locally, e.g. Flame CUTTING; Working BY Laser Beam). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2015. By volume, Changwon sits between Cellwize Wireless Technologies Ltd. and Chol, Inc..

Changwon's three-year grant acceleration

Changwon National University Industry Academy Cooperation Corps shows 1 grants in 2022–2024 against only 5 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.
