What this shows Nanotech's Innovation Score is 46.5/100 (top 21% 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 Nanotech?

Each dot is one of Nanotech’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). Nanotech’s own 19.6 claims/patent is ABOVE the 17.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Nanotech's grants concentrate

Nanotech Energy, Inc. is a focused PatentsView assignee: 14 CPC subclasses with 37.5% of grants classified under C01B (Non-metallic ELEMENTS; Compounds THEREOF; ; Metalloids OR Compounds Thereof NOT Covered BY Subclass C01c). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2017. By volume, Nanotech sits between Nugen Technologies, Inc. and New Mexico Tech University Research Park Corporation.

Nanotech's three-year grant acceleration

Nanotech Energy, Inc. shows 7 grants in 2022–2024 against only 4 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.
