Patent No. EP2720616 (titled "Device For Taking And Processing A Sample") was filed by Dino on Jun 14, 2011. The application was issued on Feb 24, 2021.
A sample processing device, specifically for stool, comprises an accommodating tube with a liquid-filled mixing chamber and a hollow, open-ended sampling rod. The rod features a capillary sampling chamber formed by projecting blades. An ejecting plunger, consisting of a head part, a conically expanded portion, and a constant-diameter straight portion, forms the sampling chamber's bottom. The head part is sealingly guided in a first channel, while the plunger portions are sealingly guided in a second channel tapered toward the sampling chamber. The head part is repositionable along the first channel to displace the plunger's distal end into the mixing chamber, ejecting the sample. The device enables qualitative and quantitative determination of substances across varying sample consistencies, from liquid to very solid.

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.
