Does more volume mean deeper claims for Zephyrtel?

Each dot is one of Zephyrtel’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). Zephyrtel’s own 22.3 claims/patent is ABOVE the 8.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Zephyrtel's grants concentrate

Zephyrtel, Inc. is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under H04L (Transmission OF Digital Information, e.g. Telegraphic Communication). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2020. By volume, Zephyrtel sits between ZARBAÑA Digital Fund LLC and Zhejiang Dingli Machinery Co., Ltd..

Zephyrtel's three-year grant acceleration

Zephyrtel, Inc. shows 5 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.
