What this shows Korea's Innovation Score is 38.0/100 (top 42% 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 Korea?

Each dot is one of Korea’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). Korea’s own 9.7 claims/patent is at or below the 15.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Korea's grants concentrate

Korea Photonics Technology Institute is a focused PatentsView assignee: 24 CPC subclasses with 29.6% of grants classified under H10H (Inorganic Light-emitting Semiconductor Devices Having Potential Barriers). Peak complete grant year is 2017 (5 grants) versus a trough of 1 in 2018. By volume, Korea sits between Kleemann GmbH and Laila Nutraceuticals.

Korea's three-year grant acceleration

Korea Photonics Technology Institute shows 4 grants in 2022–2024 against only 8 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.
