USPTO PatentsView assignee record - 11 granted patents across 7 technology areas, active 2015–2017. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: H01J (ELECTRIC DISCHARGE TUBES OR DISCHARGE LAMPS).
The verdict
SEN holds 11 US patents across 7 technology areas, rank #25,125 of 50,000 tracked assignees.
SEN Corporation has been granted 11 US utility patents between 2015 and 2017, placing SEN Corporation at rank #25,125 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.0 claims per patent with primary concentration in H01J (ELECTRIC DISCHARGE TUBES OR DISCHARGE LAMPS). As a Foreign Corporation, SEN Corporation is one of the more focused assignees in the PatentsView dataset. By volume, SEN sits between Sejin-igb Co., Ltd. (11 patents, rank #25,121) and Shandong Normal University (11 patents, rank #25,129) - the closest US assignees by grant volume. The composite Innovation Score of 25.1/100 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 0 grants, compared with 11 in the 2015–2019 window, a -100% 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. SEN Corporation's 12.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SEN Corporation against peers pursuing similar technology classes.

How to use this portfolio
SEN's 11 grants land it in the top 84% 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.
