Portfolio overview

Teijin Frontier Co., Ltd. has been granted 25 US utility patents between 2015 and 2025, placing Teijin Frontier Co., Ltd. at rank #12,250 across all assignees tracked by PlainPatent. This portfolio spans 40 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.2 claims per patent with primary concentration in D10B (INDEXING SCHEME ASSOCIATED WITH SUBLASSES OF SECTION D, RELATING TO TEXTILES). As a Foreign Corporation, Teijin Frontier Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Teijin sits between T Stamp Inc. (25 patents, rank #12,246) and THE Parallax Group International, Llc (25 patents, rank #12,254) - the closest US assignees by grant volume. The composite Innovation Score of 47.7/100 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 18 grants, compared with 7 in the 2015–2019 window, a +157% 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. Teijin Frontier Co., Ltd.'s 11.2 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 40 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Teijin Frontier 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.
