What this shows Masterflex's Innovation Score is 42.3/100 (top 31% 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 Masterflex?

Each dot is one of Masterflex’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). Masterflex’s own 7.5 claims/patent is at or below the 12.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Masterflex's grants concentrate

Masterflex, LLC is a focused PatentsView assignee: 6 CPC subclasses with 38.5% of grants classified under F04B (Positive-displacement Machines FOR LIQUIDS; Pumps). Peak complete grant year is 2024 (6 grants) versus a trough of 2 in 2022. By volume, Masterflex sits between Mankind Pharma Ltd. and Mayht Holding B.V..

Masterflex's three-year grant acceleration

Masterflex, LLC shows 11 grants in 2022–2024 against only 0 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.
