What this shows MAC's Innovation Score is 37.6/100 (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 MAC?

Each dot is one of MAC’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). MAC’s own 21.1 claims/patent is ABOVE the 11.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where MAC's grants concentrate

MAC Valves, Inc. is a focused PatentsView assignee: 8 CPC subclasses with 91.3% of grants classified under F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; Devices FOR Venting OR Aerating). Peak complete grant year is 2020 (6 grants) versus a trough of 1 in 2016. By volume, MAC sits between Locator IP, L.P. and MAX-DELBRÜCK-CENTRUM FÜR Molekulare Medizin IN DER.

MAC's three-year grant acceleration

MAC Valves, Inc. shows 6 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.
