USPTO PatentsView assignee record - 10 granted patents across 3 technology areas, active 2015–2023. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: B65D (CONTAINERS FOR STORAGE OR TRANSPORT OF ARTICLES OR MATERIALS, e.g. BAGS, BARRELS, BOTTLES, BOXES, CANS, CARTONS, CRATES, DRUMS, JARS, TANKS, HOPPERS, FORWARDING CONTAINERS; ACCESSORIES, CLOSURES, OR F).
The verdict
CDF holds 10 US patents across 3 technology areas, rank #25,953 of 50,000 tracked assignees.
CDF Corporation has been granted 10 US utility patents between 2015 and 2023, placing CDF Corporation at rank #25,953 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.0 claims per patent with primary concentration in B65D (CONTAINERS FOR STORAGE OR TRANSPORT OF ARTICLES OR MATERIALS, e.g. BAGS, BARRELS, BOTTLES, BOXES, CANS, CARTONS, CRATES, DRUMS, JARS, TANKS, HOPPERS, FORWARDING CONTAINERS; ACCESSORIES, CLOSURES, OR F). As a US Corporation, CDF Corporation is one of the more focused assignees in the PatentsView dataset. By volume, CDF sits between Cathay R&D Center Co., Ltd (10 patents, rank #25,949) and Cellspect Co., Ltd. (10 patents, rank #25,957) - the closest US assignees by grant volume. The composite Innovation Score of 29.7/100 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 6 grants, compared with 4 in the 2015–2019 window, a +50% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. CDF Corporation's 20.0 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark CDF Corporation against peers pursuing similar technology classes.

How to use this portfolio
CDF's 10 grants land it in the top 68% 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.
