USPTO PatentsView assignee record - 32 granted patents across 16 technology areas, active 2020–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: F03G (SPRING, WEIGHT, INERTIA OR LIKE MOTORS; MECHANICAL-POWER PRODUCING DEVICES OR MECHANISMS, NOT OTHERWISE PROVIDED FOR OR USING ENERGY SOURCES NOT OTHERWISE PROVIDED FOR).
The verdict
Energy holds 32 US patents across 16 technology areas, rank #9,759 of 50,000 tracked assignees.
Energy Vault, Inc. has been granted 32 US utility patents between 2020 and 2025, placing Energy Vault, Inc. at rank #9,759 across all assignees tracked by PlainPatent. This portfolio spans 16 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.3 claims per patent with primary concentration in F03G (SPRING, WEIGHT, INERTIA OR LIKE MOTORS; MECHANICAL-POWER PRODUCING DEVICES OR MECHANISMS, NOT OTHERWISE PROVIDED FOR OR USING ENERGY SOURCES NOT OTHERWISE PROVIDED FOR). As a US Corporation, Energy Vault, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Energy sits between Eurofilters Holding N.v. (32 patents, rank #9,755) and Fabric8labs, Inc. (32 patents, rank #9,763) - the closest US assignees by grant volume. The composite Innovation Score of 57.8/100 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. Historical data spans 2020 through 2025, with 32 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Energy Vault, Inc.'s 19.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 16 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Energy Vault, Inc. against peers pursuing similar technology classes.

How to use this portfolio
Energy's 32 grants land it in the top 5% 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.
