What this shows Korea's Innovation Score is 52.5/100 (top 10% 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 15.2 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 Korea's grant cadence moved

Between 2020–2024, Korea Electrotechnology Research Institute received 21 grants versus 41 in 2015–2019 (-49% equal-window velocity, below median growth). Across complete PatentsView years, output peaked in 2015 at 10 grants and bottomed in 2022 at 3. Lead class Y02E accounts for 21.2% of the portfolio across 60 subclasses. Volume neighbours: Jacobs Vehicle Systems, Inc. (#5,215) and Liebherr-werk Biberach GMBH (#5,223).

Korea's three-year grant acceleration

Korea Electrotechnology Research Institute shows 11 grants in 2022–2024 against only 19 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.
