Does more volume mean deeper claims for Zephyr?

Each dot is one of Zephyr’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). Zephyr’s own 13.6 claims/patent is ABOVE the 9.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Zephyr's grants concentrate

Zephyr Lock, LLC is a focused PatentsView assignee: 8 CPC subclasses with 37.5% of grants classified under E05B (LOCKS; Accessories THEREFOR; Handcuffs). Peak complete grant year is 2019 (8 grants) versus a trough of 1 in 2015. By volume, Zephyr sits between Xiamen Sunnypet Products Co., Ltd and olloclip, LLC.

Zephyr's three-year grant acceleration

Zephyr Lock, LLC shows 4 grants in 2022–2024 against only 9 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.
