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.
Patent citations refer to prior patents cited during different phases such as opposition or international search.
NPL citations refer to non-patent references such as research papers, articles, or other publications cited during examination or opposition phases.
