Portfolio overview

Kuraray Kuraflex Co., Ltd. has been granted 5 US utility patents between 2015 and 2021, placing Kuraray Kuraflex Co., Ltd. at rank #48,157 across all assignees tracked by PlainPatent. This portfolio spans 16 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.0 claims per patent with primary concentration in A61Q (SPECIFIC USE OF COSMETICS OR SIMILAR TOILETRY PREPARATIONS). As a Foreign Corporation, Kuraray Kuraflex Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Kuraray sits between KUKA Laboratories Gmbh (5 patents, rank #48,153) and KVI Llc (5 patents, rank #48,161) - the closest US assignees by grant volume. The composite Innovation Score of 29.3/100 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. Between 2020 and 2025 the company received 1 grants, compared with 4 in the 2015–2019 window, a -75% 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. Kuraray Kuraflex Co., Ltd.'s 15.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 16 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kuraray Kuraflex 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.
