Portfolio overview
EPISURF IP-MANAGEMENT AB has been granted 37 US utility patents between 2016 and 2025, placing EPISURF IP-MANAGEMENT AB at rank #8,581 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.8 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 Foreign Corporation, EPISURF IP-MANAGEMENT AB is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 37.8/100 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 24 grants, compared with 13 in the 2015–2019 window — a +85% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. EPISURF IP-MANAGEMENT AB's 12.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark EPISURF IP-MANAGEMENT AB against peers pursuing similar technology classes.
