Headphone

Patent No. EP3403416 (titled "Headphone") was filed by Bose on Jan 11, 2017. The application was issued on Jun 25, 2025.

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.
