Patent No. EP3503715 (titled "Arrangement And Method For Classifying Teats With Respect To Size Measures") was filed by Delaval Holding on Aug 24, 2017. The application was issued on May 4, 2022.
An automatic milking system arrangement comprises a three-dimensional camera for recording image data of a dairy animal's teat outer surface and a processing unit for geometric analysis. The processing unit calculates at least one teat size measure (W1, W2, L) from the image data to determine a size-related classification and a corresponding recommended teatcup liner. A user interface presents output data reflecting this classification. The processing unit may combine multiple images into composite data or perform statistical analysis across animal groups to determine common size classifications and collective liner recommendations. The system may further subdivide livestock into subgroups based on teat measures for use in multiple milking installations. The 3D camera may also provide image data to a control unit managing a movable robot arm.

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.
