The verdict

Sekisui Specialty Chemicals America, Llc has been granted 11 US utility patents between 2015 and 2025, placing Sekisui Specialty Chemicals America, Llc at rank #25,122 across all assignees tracked by PlainPatent. This portfolio spans 17 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.1 claims per patent with primary concentration in C08F (MACROMOLECULAR COMPOUNDS OBTAINED BY REACTIONS ONLY INVOLVING CARBON-TO-CARBON UNSATURATED BONDS). As a US Corporation, Sekisui Specialty Chemicals America, Llc is one of the more focused assignees in the PatentsView dataset. By volume, Sekisui sits between Scott Cutters Limited (11 patents, rank #25,118) and Sequans Communications Ltd. (11 patents, rank #25,126) - the closest US assignees by grant volume. The composite Innovation Score of 36.2/100 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 5 grants, compared with 6 in the 2015–2019 window, a -17% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US 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 Specialty Chemicals America, Llc's 18.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 17 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sekisui Specialty Chemicals America, Llc against peers pursuing similar technology classes.

How to use this portfolio
Sekisui's 11 grants land it in the top 47% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
