What this tool is, and is not. It applies general rules to what you type in. It cannot see your file, your applicant category, which amendment governs your application, or what the Patent Office has issued. Nothing here is a legal opinion or a diary entry. Have anything that matters confirmed by a patent professional against the instrument in force.
