Portfolio overview

Sekisui Medical Co., Ltd. has been granted 113 US utility patents between 2015 and 2025, placing Sekisui Medical Co., Ltd. at rank #3,312 across all assignees tracked by PlainPatent. This portfolio spans 35 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.1 claims per patent with primary concentration in G01N (INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES). As a Foreign Corporation, Sekisui Medical Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Sekisui sits between Mikuni Corporation (113 patents, rank #3,308) and Xiamen Lota International Co., Ltd. (113 patents, rank #3,316) - the closest US assignees by grant volume. The composite Innovation Score of 47.0/100 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 46 grants, compared with 67 in the 2015–2019 window, a -31% 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. Sekisui Medical Co., Ltd.'s 10.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 35 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sekisui Medical 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.
