Q: How is the Mitsubishi Engineering-Plastics Corporation patent data sourced?

All patent data comes from USPTO PatentsView, a public research dataset maintained by the United States Patent and Trademark Office covering US granted utility patents from 2015 to 2025.

USPTO PatentsView assignee record - 56 granted patents across 33 technology areas, recorded in grant years 2015–2025. Grant-trend analysis is cross-referenced to USPTO Patent Public Search; it does not measure application filings, current R&D, or legal strength. Primary class: C08L (Compositions OF Macromolecular Compounds).

What this shows Mitsubishi's Innovation Score is 47.3/100 (top 19% 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 Mitsubishi?

Each dot is one of Mitsubishi’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). Mitsubishi’s own 14.6 claims/patent is at or below the 16.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Mitsubishi's grants concentrate

Mitsubishi Engineering-Plastics Corporation is a focused PatentsView assignee: 33 CPC subclasses with 91.1% of grants classified under C08L (Compositions OF Macromolecular Compounds). Peak complete grant year is 2017 (9 grants) versus a trough of 1 in 2024. By volume, Mitsubishi sits between Musarubra US LLC and Mycronic AB.

Mitsubishi's three-year grant acceleration

Mitsubishi Engineering-Plastics Corporation shows 12 grants in 2022–2024 against only 19 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.
