What this shows Mar's Innovation Score is 26.6/100 (21st 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 Mar?

Each dot is one of Mar’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). Mar’s own 9.8 claims/patent is at or below the 12.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Mar's grants concentrate

Mar Cor Purification, Inc. is a focused PatentsView assignee: 5 CPC subclasses with 40% of grants classified under A61L (Methods OR Apparatus FOR Sterilising Materials OR Objects IN GENERAL; Disinfection, Sterilisation OR Deodorisation OF AIR; Chemical Aspects OF Bandages, Dressings, Absorbent Pads OR Surgical ARTICLES;). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2018. By volume, Mar sits between Mantissa Corporation and Marel Power Solutions, Inc..

Mar's three-year grant acceleration

Mar Cor Purification, Inc. shows 1 grants in 2022–2024 against only 1 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.
