Syllabus

<p>1. Patents — Invention—Oil Burners.</p> <p>The Jeavons patent, No. 702,560, for an oil burner, does not disclose a new mechanism or combination, but merely a new use for an old and well-known mechanism, and is void for lack of patentable invention.</p> <p>2. Same — Presumption of Validity.</p> <p>The presumption of validity, due to the grant of a patent, is qualified by the fact that prior patents, material to a just estimate of the art, were not cited or considered by the examiner.</p>
