What this shows ZT's Innovation Score is 62.5/100 (top 2% 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 ZT?

Each dot is one of ZT’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). ZT’s own 16.7 claims/patent is ABOVE the 15.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where ZT's grants concentrate

ZT Group Int'l, Inc. is a focused PatentsView assignee: 26 CPC subclasses with 71.2% of grants classified under H05K (Printed CIRCUITS; Casings OR Constructional Details OF Electric APPARATUS; Manufacture OF Assemblages OF Electrical Components). Peak complete grant year is 2024 (18 grants) versus a trough of 1 in 2020. By volume, ZT sits between University of Puerto Rico and Buerkert Werke GMBH.

ZT's three-year grant acceleration

ZT Group Int'l, Inc. shows 44 grants in 2022–2024 against only 10 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.
