Does more volume mean deeper claims for Nanostone?

Each dot is one of Nanostone’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). Nanostone’s own 19.0 claims/patent is ABOVE the 14.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Nanostone's grants concentrate

Nanostone Water Inc. is a focused PatentsView assignee: 5 CPC subclasses with 75% of grants classified under B01D (Separation). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2017. By volume, Nanostone sits between Nano 2.0 Business Press, LLC and National Kaohsiung First University of Science and Technology.

Nanostone's three-year grant acceleration

Nanostone Water Inc. shows 2 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.
