Extensible File System

Patent No. EP1677214 (titled "Extensible File System") was filed by MICROSOFT CORPORATION on Dec 1, 2005. The application was issued on May 7, 2014.

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.
