What this shows Nrgtek's Innovation Score is 27.5/100 (24th percentile 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 Nrgtek?

Each dot is one of Nrgtek’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). Nrgtek’s own 6.8 claims/patent is at or below the 16.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nrgtek's grants concentrate

Nrgtek, Inc. is a focused PatentsView assignee: 14 CPC subclasses with 77.8% of grants classified under B01D (Separation). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2016. By volume, Nrgtek sits between Novelis Koblenz GMBH and Nuheart AS.

Nrgtek's three-year grant acceleration

Nrgtek, Inc. shows 1 grants in 2022–2024 against only 3 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.
