The verdict
Dominion holds 8 US patents across 13 technology areas, rank #31,400 of 50,000 tracked assignees.
Dominion Engineering, Inc. has been granted 8 US utility patents between 2016 and 2022, placing Dominion Engineering, Inc. at rank #31,400 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.3 claims per patent with primary concentration in G21C (NUCLEAR REACTORS). As a US Corporation, Dominion Engineering, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Dominion sits between DMC, Inc (8 patents, rank #31,396) and Douxmatok Ltd (8 patents, rank #31,404) - the closest US assignees by grant volume. The composite Innovation Score of 38.0/100 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 4 grants, compared with 4 in the 2015–2019 window, a +0% 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. Dominion Engineering, Inc.'s 18.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Dominion Engineering, Inc. against peers pursuing similar technology classes.

How to use this portfolio
Dominion's 8 grants land it in the top 42% 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.
