Patent No. EP4609108 (titled "Valve With Ventilation Function") was filed by VTI Ventil Technik on Nov 2, 2023. The application was issued on Dec 31, 2025.
A valve (1) connects a pressure source (3) to at least one consumer via a valve body containing a pressure channel (4). Integrated into this channel is a vent valve (2) featuring an axially displaceable bolt (12). The bolt is maintained in an operating position but can be axially displaced into a venting position to release pressure from the channel (4) to the environment (U). The vent valve (2) comprises an outer sleeve (13) in which the bolt (12) is axially mounted, or alternatively, the bolt (12) is integrated directly into a bore (26) within the valve (1). This configuration enables safe depressurization of high-pressure lines, such as CO₂ fire protection or pneumatic tool systems, prior to disconnection.

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.
