Patent No. EP3222176 (titled "Machine And System For The Preparation Of Liquid Products Using Capsules") was filed by Luigi Lavazza on Jun 17, 2014. The application was issued on Feb 8, 2023.
A liquid food preparation machine utilizes a dispensing assembly with a first part and second part forming an infusion chamber. A loading arrangement includes an insertion guide defining a capsule displacement path toward a loading position. An actuation system moves the infusion chamber parts in a direction generally transverse to the capsule's movement. A control system, comprising processing means, non-volatile memory, and a laterally mounted optical sensor, acquires characteristic information from a capsule end wall while the capsule is held at an intermediate retention position by switchable first retaining means. These means release the capsule via a thrust force. The processing means select an operating mode from multiple options based on the acquired characteristic information and encoded instructions in the memory.

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.
