The same four weighted components behind every Innovation Score on PlainPatent: portfolio volume, grant velocity, technology breadth, and claim depth.

What this shows Merck's Innovation Score is 33.1/100 (43rd 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 Merck?
Each dot is one of Merck’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). Merck’s own 14.9 claims/patent is at or below the 15.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Merck's grants concentrate
Merck Millipore Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 88.9% of grants classified under B01D (Separation). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2021. By volume, Merck sits between Meijer, Inc. and Metamagnetics, Inc..
Merck's three-year grant acceleration
Merck Millipore Ltd. shows 3 grants in 2022–2024 against only 4 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.
