Patent No. EP3563360 (titled "Method And Control Unit For Enhanced Safety In An Agricultural Environment") was filed by Delaval Holding on Dec 22, 2017. The application was issued on Aug 9, 2023.
An agricultural security system (600) comprises a stationary agricultural structure (105) with a moving part (110)—such as a robotic arm, rotating milking platform, or gate—a control unit (120), and wireless signal receivers (130a-c). A human user (200) carries a locational device (115) associated with a portable electronic device (150). The control unit obtains the locational device's geographical position to determine its distance from the structure. If this distance falls below a threshold limit (310b), the unit triggers an accident avoidance measure by deactivating the moving part. If the distance falls below an additional threshold limit (310c), the unit pairs the portable electronic device with the structure, enabling the user to adjust the structure's parameters via the portable device.

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.
