What this shows Namuga's Innovation Score is 42.2/100 (top 31% 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 Namuga?

Each dot is one of Namuga’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). Namuga’s own 15.1 claims/patent is at or below the 19.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Namuga's grants concentrate

Namuga Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 56.3% of grants classified under H01S (Devices Using THE Process OF Light Amplification BY Stimulated Emission OF Radiation [LASER] TO Amplify OR Generate LIGHT; Devices Using Stimulated Emission OF Electromagnetic Radiation IN Wave Ranges). Peak complete grant year is 2023 (5 grants) versus a trough of 1 in 2018. By volume, Namuga sits between NSK Americas, Inc. and Neozyme International, Inc..

Namuga's three-year grant acceleration

Namuga Co., Ltd. shows 10 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.
