Method And Device For Encoding Polar Code

Patent No. EP3457606 (titled "Method And Device For Encoding Polar Code") was filed by Huawei on May 4, 2018. The application was issued on May 18, 2022.

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.
