The verdict
DEAN holds 5 US patents across 5 technology areas, rank #46,046 of 50,000 tracked assignees.
DEAN Technology Inc. has been granted 5 US utility patents between 2018 and 2020, placing DEAN Technology Inc. at rank #46,046 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.0 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 US Corporation, DEAN Technology Inc. is one of the more focused assignees in the PatentsView dataset. By volume, DEAN sits between DCR IP Company, Llc (5 patents, rank #46,042) and DEEP Instinct (5 patents, rank #46,050) - the closest US assignees by grant volume. The composite Innovation Score of 20.1/100 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 1 grants, compared with 4 in the 2015–2019 window, a -75% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. DEAN Technology Inc.'s 10.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark DEAN Technology Inc. against peers pursuing similar technology classes.

How to use this portfolio
DEAN's 5 grants land it in the top 93% 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.
