Portfolio overview

ASAHI KASEI FIBERS CORPORATION has been granted 33 US utility patents between 2015 and 2020, placing ASAHI KASEI FIBERS CORPORATION at rank #9,426 across all assignees tracked by PlainPatent. This portfolio spans 45 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.4 claims per patent with primary concentration in Y10T (TECHNICAL SUBJECTS COVERED BY FORMER US CLASSIFICATION). As a Foreign Corporation, ASAHI KASEI FIBERS CORPORATION is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 41.5/100 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 1 grants, compared with 32 in the 2015–2019 window, a -97% 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. ASAHI KASEI FIBERS CORPORATION's 9.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 45 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark ASAHI KASEI FIBERS CORPORATION against peers pursuing similar technology classes.

How to use this portfolio

Asahi's 33 grants land it in the top 33% 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 - Asahi ranks #9,426 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in Y10T - see who else leads that technology area. Y10T 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.
