USPTO PatentsView assignee record - 24 granted patents across 20 technology areas, active 2015–2024. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: B61L (GUIDING RAILWAY TRAFFIC; ENSURING THE SAFETY OF RAILWAY TRAFFIC).
The verdict
Ensco holds 24 US patents across 20 technology areas, rank #12,427 of 50,000 tracked assignees.
Ensco, Inc. has been granted 24 US utility patents between 2015 and 2024, placing Ensco, Inc. at rank #12,427 across all assignees tracked by PlainPatent. This portfolio spans 20 distinct Cooperative Patent Classification (CPC) subclasses, averaging 22.7 claims per patent with primary concentration in B61L (GUIDING RAILWAY TRAFFIC; ENSURING THE SAFETY OF RAILWAY TRAFFIC). As a US Corporation, Ensco, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Ensco sits between Dyno Nobel Inc. (24 patents, rank #12,423) and Exposure Illumination Architects, Inc. (24 patents, rank #12,431) - the closest US assignees by grant volume. The composite Innovation Score of 60.6/100 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 16 grants, compared with 8 in the 2015–2019 window, a +100% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Ensco, Inc.'s 22.7 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while a multi-domain presence across 20 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Ensco, Inc. against peers pursuing similar technology classes.

How to use this portfolio
Ensco's 24 grants land it in the top 3% 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.
