What this shows Matcor's Innovation Score is 26.5/100 (20th 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 Matcor?

Each dot is one of Matcor’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). Matcor’s own 13.4 claims/patent is at or below the 17.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Matcor's grants concentrate

Matcor, Inc. is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under C23F (Non-mechanical Removal OF Metallic Material From Surface ; Inhibiting Corrosion OF Metallic Material OR Incrustation IN GENERAL; Multi-step Processes FOR Surface Treatment OF Metallic Material Involvi). By volume, Matcor sits between Martek Limited, LLC and Matrix X, LLC.

Matcor's three-year grant acceleration

Matcor, Inc. shows 1 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.
