What this shows Nuburu's Innovation Score is 44.4/100 (top 26% 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 Nuburu?

Each dot is one of Nuburu’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). Nuburu’s own 27.9 claims/patent is ABOVE the 16.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Nuburu's grants concentrate

Nuburu, Inc. is a focused PatentsView assignee: 9 CPC subclasses with 57.1% 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 2024 (6 grants) versus a trough of 4 in 2020. By volume, Nuburu sits between Nippon Signal Co., Ltd. and Opswat Inc..

Nuburu's three-year grant acceleration

Nuburu, Inc. shows 11 grants in 2022–2024 against only 9 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.
