What this shows ZMC's Innovation Score is 27.2/100 (23rd percentile 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 ZMC?

Each dot is one of ZMC’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). ZMC’s own 3.9 claims/patent is at or below the 15.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where ZMC's grants concentrate

ZMC Metal Coating Inc. is a focused PatentsView assignee: 9 CPC subclasses with 44.8% of grants classified under E06B (Fixed OR Movable Closures FOR Openings IN Buildings, Vehicles, Fences OR Like Enclosures IN General, e.g. Doors, Windows, Blinds, Gates). Peak complete grant year is 2016 (5 grants) versus a trough of 1 in 2022. By volume, ZMC sits between Yodlee, Inc. and 6K Inc..

ZMC's three-year grant acceleration

ZMC Metal Coating Inc. shows 3 grants in 2022–2024 against only 8 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.
