The verdict
L3 holds 7 US patents across 6 technology areas, rank #36,166 of 50,000 tracked assignees.
L3 Open Water Power, Inc. has been granted 7 US utility patents between 2018 and 2021, placing L3 Open Water Power, Inc. at rank #36,166 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.0 claims per patent with primary concentration in H01M (PROCESSES OR MEANS, e.g. BATTERIES, FOR THE DIRECT CONVERSION OF CHEMICAL ENERGY INTO ELECTRICAL ENERGY). As a US Corporation, L3 Open Water Power, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, L3 sits between Kühne Jungpflanzen Claus + Torsten Kühne Gbr (7 patents, rank #36,162) and Lappeenrannan Teknillinen Yliopisto (7 patents, rank #36,170) - the closest US assignees by grant volume. The composite Innovation Score of 24.2/100 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 4 grants, compared with 3 in the 2015–2019 window, a +33% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. L3 Open Water Power, Inc.'s 14.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 6 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark L3 Open Water Power, Inc. against peers pursuing similar technology classes.

How to use this portfolio
L3's 7 grants land it in the top 86% 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.
