Does more volume mean deeper claims for Zest?

Each dot is one of Zest’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). Zest’s own 12.2 claims/patent is ABOVE the 9.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Zest's grants concentrate

Zest IP Holdings, LLC is a focused PatentsView assignee: 5 CPC subclasses with 88.5% of grants classified under A61C (DENTISTRY; Apparatus OR Methods FOR Oral OR Dental Hygiene). Peak complete grant year is 2016 (5 grants) versus a trough of 1 in 2017. By volume, Zest sits between Yazaki Energy System Corporation and Zhejiang Medicine Co., Ltd. Xinchang Pharmaceutical Factory.

Zest's three-year grant acceleration

Zest IP Holdings, LLC shows 9 grants in 2022–2024 against only 6 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.
