Syllabus

<p>1. Patents—Infringement—Fountain Pens.</p> <p>The Waterman patent, No. 604,690, relating to caps for fountain pens, claims 8 and 9, which cover a cap composed of an internal and external conical member, are not infringed by a, cap in which the interior of the external member is not conical, but consists of two cylinders, the upper being smaller than the lower. Claims 17 to 26, which cover a conical interior member, and a cap which is elastic, or has an elastic mouth, to make a tight joint, but without specifying any particular material, are void for lack of invention, such joints being old in the art, and in others in which they were used for a similar purpose.</p>
