Patent No. EP3810953 (titled "Spring For Friction Pads In A Disc Brake Caliper") was filed by Brembo on Jun 6, 2019. The application was issued on Jun 11, 2025.
A spring for retaining and positioning brake pads in a disc brake caliper, comprising a longitudinal piece that engages support pins from the side and a cross piece that presses against the pads from the side, rather than from above, to provide a more consistent and predictable elastic force that maintains pad separation and prevents residual braking torque.

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.
