Portfolio overview

DOW TRAY Co., Ltd. has been granted 116 US utility patents between 2019 and 2025, placing DOW TRAY Co., Ltd. at rank #3,224 across all assignees tracked by PlainPatent. This portfolio spans 52 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.9 claims per patent with primary concentration in C08G (MACROMOLECULAR COMPOUNDS OBTAINED OTHERWISE THAN BY REACTIONS ONLY INVOLVING UNSATURATED CARBON-TO-CARBON BONDS). As a Foreign Corporation, DOW TRAY Co., Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, DOW sits between Arena Pharmaceuticals, Inc. (116 patents, rank #3,220) and Hasbro, Inc. (116 patents, rank #3,228) - the closest US assignees by grant volume. The composite Innovation Score of 59.8/100 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. Between 2020 and 2025 the company received 108 grants, compared with 8 in the 2015–2019 window, a +1250% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. DOW TRAY Co., Ltd.'s 13.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 52 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark DOW TRAY Co., Ltd. against peers pursuing similar technology classes.

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.
