Treatment of generalized demodicosis in dogs using a single oral dose of the isoxazoline compound fluralaner, which achieves complete mite clearance and resolves skin lesions without the need for repeated treatments or topical applications.

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.
