USPTO PatentsView assignee record - 11 granted patents across 4 technology areas, active 2022–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: H02M (APPARATUS FOR CONVERSION BETWEEN AC AND AC, BETWEEN AC AND DC, OR BETWEEN DC AND DC, AND FOR USE WITH MAINS OR SIMILAR POWER SUPPLY SYSTEMS; CONVERSION OF DC OR AC INPUT POWER INTO SURGE OUTPUT POWER;).
The verdict
Ecoflow holds 11 US patents across 4 technology areas, rank #24,234 of 50,000 tracked assignees.
Ecoflow Inc. has been granted 11 US utility patents between 2022 and 2025, placing Ecoflow Inc. at rank #24,234 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.3 claims per patent with primary concentration in H02M (APPARATUS FOR CONVERSION BETWEEN AC AND AC, BETWEEN AC AND DC, OR BETWEEN DC AND DC, AND FOR USE WITH MAINS OR SIMILAR POWER SUPPLY SYSTEMS; CONVERSION OF DC OR AC INPUT POWER INTO SURGE OUTPUT POWER;). As a Foreign Corporation, Ecoflow Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Ecoflow sits between E8 Storage Systems Ltd. (11 patents, rank #24,230) and Effect Photonics B.v. (11 patents, rank #24,238) - the closest US assignees by grant volume. The composite Innovation Score of 40.6/100 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. Historical data spans 2022 through 2025, with 11 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Ecoflow Inc.'s 8.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Ecoflow Inc. against peers pursuing similar technology classes.

How to use this portfolio
Ecoflow's 11 grants land it in the top 35% 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.
