What this shows Zentech's Innovation Score is 37.5/100 (top 43% 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 Zentech?

Each dot is one of Zentech’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). Zentech’s own 19.0 claims/patent is ABOVE the 16.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Zentech's grants concentrate

Zentech, Inc. is a focused PatentsView assignee: 13 CPC subclasses with 66.7% of grants classified under E02B (Hydraulic Engineering). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2016. By volume, Zentech sits between Zedel S.A. and ZeroLemon LLC.

Zentech's three-year grant acceleration

Zentech, Inc. shows 2 grants in 2022–2024 against only 2 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.
