What this shows EMD's Innovation Score is 27.5/100 (24th 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.

Where EMD's grants concentrate

EMD Corporation is a focused PatentsView assignee: 6 CPC subclasses with 60% of grants classified under H01J (Electric Discharge Tubes OR Discharge Lamps). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2019. By volume, EMD sits between Elmac Technologies Limited and EMS Engineered Materials Solutions, LLC.

EMD's three-year grant acceleration

EMD Corporation 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.
