Portfolio overview

Teijin Aramid B.v. has been granted 38 US utility patents between 2015 and 2025, placing Teijin Aramid B.v. at rank #8,486 across all assignees tracked by PlainPatent. This portfolio spans 40 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.3 claims per patent with primary concentration in D21H (PULP COMPOSITIONS; PREPARATION THEREOF NOT COVERED BY SUBCLASSES D21C OR D21D; IMPREGNATING OR COATING OF PAPER; TREATMENT OF FINISHED PAPER NOT COVERED BY CLASS B31 OR SUBCLASS D21G; PAPER NOT OTHERW). As a Foreign Corporation, Teijin Aramid B.v. is one of the more focused assignees in the PatentsView dataset. By volume, Teijin sits between Siluria Technologies, Inc. (38 patents, rank #8,482) and Total SE (38 patents, rank #8,490) - the closest US assignees by grant volume. The composite Innovation Score of 47.8/100 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 18 grants, compared with 20 in the 2015–2019 window, a -10% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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 Aramid B.v.'s 15.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, 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 Aramid B.v. against peers pursuing similar technology classes.

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.
