Does more volume mean deeper claims for Electrosea?

Each dot is one of Electrosea’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). Electrosea’s own 21.1 claims/patent is ABOVE the 12.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Electrosea's grants concentrate

ElectroSea, LLC is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2021. By volume, Electrosea sits between Eickhof Columbaria, Inc. and Eliaz Therapeutics, Inc..

Electrosea's three-year grant acceleration

ElectroSea, LLC shows 5 grants in 2022–2024 against only 1 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.
