What this shows Nufern's Innovation Score is 38.5/100 (top 41% 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 Nufern?

Each dot is one of Nufern’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). Nufern’s own 22.1 claims/patent is ABOVE the 16.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Nufern's grants concentrate

Nufern is a focused PatentsView assignee: 13 CPC subclasses with 76.5% 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 2020 (5 grants) versus a trough of 1 in 2015. By volume, Nufern sits between Northwest Institute of Eco-Environment and Resources, Chinese Academy of Sciences and Oclaro Technology Limited.

Nufern's three-year grant acceleration

Nufern shows 3 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.
