Portfolio overview

Tokyo Metropolitan Public University Corporation has been granted 8 US utility patents between 2022 and 2024, placing Tokyo Metropolitan Public University Corporation at rank #33,561 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 6.5 claims per patent with primary concentration in B33Y (ADDITIVE MANUFACTURING, i.e. MANUFACTURING OF THREE-DIMENSIONAL [3-D] OBJECTS BY ADDITIVE DEPOSITION, ADDITIVE AGGLOMERATION OR ADDITIVE LAYERING, e.g. BY 3-D PRINTING, STEREOLITHOGRAPHY OR SELECTIVE ). As a Foreign Corporation, Tokyo Metropolitan Public University Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Tokyo sits between TNP Corporation (8 patents, rank #33,557) and Toshiba Alpine Automotive Technology Corporation (8 patents, rank #33,565) - the closest US assignees by grant volume. The composite Innovation Score of 47.3/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Historical data spans 2022 through 2024, with 8 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. Tokyo Metropolitan Public University Corporation's 6.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 20 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Tokyo Metropolitan Public University Corporation against peers pursuing similar technology classes.

How to use this portfolio

Tokyo's 8 grants land it in the top 19% 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 - Tokyo ranks #33,561 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in B33Y - see who else leads that technology area. B33Y 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.
