Syllabus

<p>1. Patents (§ 141*) — Reissue—Broadening or Claims.</p> <p>While a reissue may not claim an invention not clearly shown in the original patent, a reissue is not necessarily void because its claims are broader than those of the original.</p> <p>[Ed. Note. — For other cases, see Patents, Cent. Dig. §§ 206-213; Dec. Dig. § 141.*]</p> <p>2. Patents (§ 138*) — Validity op Reissue — Laches.</p> <p>A delay of 7% months before applying for a reissue is not of itself fatal to the reissue if rights of others have not intervened.</p> <p>[Ed. Note. — For other cases, see Patents, Cent. Dig. §§ 201-203; Dee. Dig. § 138.*]</p> <p>3.
