Patent No. EP4340792 (titled "Wound Dressing") was filed by Convatec on Mar 16, 2023. The application was issued on Sep 18, 2024.
This wound dressing comprises a backing layer, a wound contact layer, and a superabsorbent layer positioned between them. The wound contact layer features a first surface for direct wound bed contact and a second surface facing the backing layer, and it is composed of gel-forming fibers. The superabsorbent layer is characterized by a blend of sodium polyacrylate fibers and polyester fibers. This configuration, combining a gelling wound contact layer with a superabsorbent layer, is designed to enhance fluid absorption, retention, and overall fluid handling capacity while maintaining a moist healing environment. The use of fibers in the superabsorbent layer specifically allows the dressing to be cut prior to use and improves conformability within a laminated structure.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
The dossier documents provide a comprehensive record of the patent's prosecution history - including filings, correspondence, and decisions made by patent offices - and are crucial for understanding the patent's legal journey and any challenges it may have faced during examination.
