Portfolio overview
Darco International, Inc. has been granted 6 US utility patents between 2015 and 2025, placing Darco International, Inc. at rank #39,743 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.5 claims per patent with primary concentration in A61F (FILTERS IMPLANTABLE INTO BLOOD VESSELS; PROSTHESES; DEVICES PROVIDING PATENCY TO, OR PREVENTING COLLAPSING OF, TUBULAR STRUCTURES OF THE BODY, e.g. STENTS; ORTHOPAEDIC, NURSING OR CONTRACEPTIVE DEVICE). As a US Corporation, Darco International, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Darco sits between DAIS Analytic Corporation (6 patents, rank #39,739) and DAY Three LABS Manufacturing Inc. (6 patents, rank #39,747) - the closest US assignees by grant volume. The composite Innovation Score of 29.2/100 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 2 in the 2015–2019 window, a +100% 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. Darco International, Inc.'s 17.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 6 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Darco International, Inc. against peers pursuing similar technology classes.
