What this shows Nanophase'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 Nanophase?

Each dot is one of Nanophase’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). Nanophase’s own 21.1 claims/patent is ABOVE the 18.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Nanophase's grants concentrate

Nanophase Technologies Corporation is a focused PatentsView assignee: 14 CPC subclasses with 90.9% of grants classified under A61Q (Specific USE OF Cosmetics OR Similar Toiletry Preparations). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2017. By volume, Nanophase sits between Nxgn Data, Inc. and Neoz Pty Ltd.

Nanophase's three-year grant acceleration

Nanophase Technologies Corporation shows 3 grants in 2022–2024 against only 5 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.
