Where Mitsubishi's grants concentrate

Mitsubishi Polycrystalline Silicon America Corporation (MIPSA) is a focused PatentsView assignee: 11 CPC subclasses with 70% of grants classified under C01B (Non-metallic ELEMENTS; Compounds THEREOF; ; Metalloids OR Compounds Thereof NOT Covered BY Subclass C01c). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2015. By volume, Mitsubishi sits between Minerva Neurosciences, Inc. and Mohawk Industries, Inc..

Mitsubishi's three-year grant acceleration

Mitsubishi Polycrystalline Silicon America Corporation (MIPSA) shows 3 grants in 2022–2024 against only 3 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.
