Portfolio overview

Doubleday Acquisitions, Llc has been granted 9 US utility patents between 2017 and 2025, placing Doubleday Acquisitions, Llc at rank #28,601 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.1 claims per patent with primary concentration in F25D (REFRIGERATORS; COLD ROOMS; ICE-BOXES; COOLING OR FREEZING APPARATUS NOT OTHERWISE PROVIDED FOR). As a US Corporation, Doubleday Acquisitions, Llc is one of the more focused assignees in the PatentsView dataset. By volume, Doubleday sits between Dongguan Kaishuo Electronics Technology Co., Ltd. (9 patents, rank #28,597) and Drive CJSC (9 patents, rank #28,605) - the closest US assignees by grant volume. The composite Innovation Score of 33.7/100 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 5 in the 2015–2019 window, a -20% 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. Doubleday Acquisitions, Llc's 16.1 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 Doubleday Acquisitions, Llc against peers pursuing similar technology classes.
