Does more volume mean deeper claims for Wota?
Each dot is one of Wota’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). Wota’s own 8.7 claims/patent is at or below the 11.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Wota's grants concentrate
Wota Corp. is a focused PatentsView assignee: 9 CPC subclasses with 83.3% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2021. By volume, Wota sits between WISErg Corporation and Wulftec International Inc..
Wota's three-year grant acceleration
Wota Corp. 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.
