Portfolio overview

Mitsubishi Materials Electronic Chemicals Co., Ltd. has been granted 27 US utility patents between 2015 and 2025, placing Mitsubishi Materials Electronic Chemicals Co., Ltd. at #11,353 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 40 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.4 claims per patent with primary concentration in C09D (COATING COMPOSITIONS, e.g. PAINTS, VARNISHES OR LACQUERS; FILLING PASTES; CHEMICAL PAINT OR INK REMOVERS; INKS; CORRECTING FLUIDS; WOODSTAINS; PASTES OR SOLIDS FOR COLOURING OR PRINTING; USE OF MATERI). As a Foreign Corporation, Mitsubishi Materials Electronic Chemicals Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Mitsubishi sits between Micron Devices Llc (27 patents, rank #11,348) and National Science Foundation (27 patents, rank #11,356) - the closest US assignees by grant volume. The composite Innovation Score of 43.9/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Grant cadence records the difference between two grant-year windows. Between 2020 and 2024 the company received 8 grants, compared with 17 in the 2015–2019 window, a -53% shift in five-year grant velocity. Both windows cover five complete grant years; the latest PatentsView year is a partial release and is excluded from this comparison, though it still appears in the yearly table and chart below. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. Mitsubishi Materials Electronic Chemicals Co., Ltd.'s 8.4 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 40 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.

How to use this portfolio

Mitsubishi's 27 grants land it in the top 27% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - Mitsubishi ranks #11,353 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in C09D - see who else leads that technology area. C09D leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
