Patent No. EP3782664 (titled "Device And Method For Separating Blood") was filed by Yapici on Aug 10, 2020. The application was issued on Dec 3, 2025.
A blood separation device, serving as a centrifugation vessel, comprises a sample tube featuring three distinct sections: a lower chamber, an observation tube, and an upper chamber. This three-section configuration ensures clear separation of blood components, reducing serum contamination and enabling use by less experienced operators. To maximize the yield of platelet-rich plasma and prevent its inactivation via wall deposition, the device is constructed from polyethylene (PE), polypropylene (PP), or other suitable materials. The device is specifically designed for medical applications requiring platelet-rich plasma to initiate or accelerate healing, such as in orthopedics, traumatology, plastic surgery, dental operations, soft tissue injuries, and bone fractures.

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.
