Does more volume mean deeper claims for Zadro?

Each dot is one of Zadro’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). Zadro’s own 8.8 claims/patent is ABOVE the 8.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Zadro's grants concentrate

Zadro, Inc. is a focused PatentsView assignee: 5 CPC subclasses with 33.3% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2019. By volume, Zadro sits between ZI YI Electrical Engineering Co., Ltd. and Zepp Labs, Inc..

Zadro's three-year grant acceleration

Zadro, Inc. shows 3 grants in 2022–2024 against only 3 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.
