What this shows Zipstring's Innovation Score is 44.6/100 (top 25% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Zipstring?

Each dot is one of Zipstring’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). Zipstring’s own 15.1 claims/patent is ABOVE the 13.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Zipstring's grants concentrate

Zipstring LLC is a focused PatentsView assignee: 5 CPC subclasses with 62.5% of grants classified under F41B (Weapons FOR Projecting Missiles Without USE OF Explosive OR Combustible Propellant CHARGE; Weapons NOT Otherwise Provided FOR). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2023. By volume, Zipstring sits between Zhejiang YAT Electrical Appliance Co., Ltd and Zumex Group, S.A..

Zipstring's three-year grant acceleration

Zipstring LLC shows 6 grants in 2022–2024 against only 0 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.
