Where Nanograf's grants concentrate

Nanograf Corporation is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under H01M (PROCESSES OR MEANS, e.g. BATTERIES, FOR THE DIRECT CONVERSION OF CHEMICAL ENERGY INTO ELECTRICAL ENERGY). Peak complete grant year is 2020 (3 grants) versus a trough of 2 in 2023. By volume, Nanograf sits between Nabors LUX 2 SARL and National Institutes OF Health (nih).

Nanograf's three-year grant acceleration

Nanograf Corporation shows 5 grants in 2022–2024 against only 6 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.
