DEFINITION

Classification: 15/435

(under subclass 104) Manually manipulable implement comprising a tool of incompressible solid material and having either a single element or a furcated plurality of elements for contacting a work surface and applying liquid coating material (e.g., ink) thereto in a writing operation; or comprising a device connectable to such a tool for supporting or retaining the tool for manual manipulation during a writing operation.

(1) Note. The line between this subclass and Class 33, Geometrical Instruments, with respect to plural penpoints, is as follows: Class 15, subclasses 760+ will take a patent for an implement having plural penpoints, wherein (1) the construction is such that the penpoints are intended to be used independently of each other, or (2) if designed for simultaneous operation, the mark produced by one penpoint complements and is contiguous to the mark (s) simultaneously produced to the other (s) to produce unitary indicia (e.g.,

shading pen); or the marks are wide enough to be characterized as stripes, rather than lines. When the plural penpoints are adapted, and used, sorely for the simultaneous drawing of a plurality of independent and spaced lines, placement of the patent will be in Class 33.

(2) Note. For the line between this subclass and the indented subclasses, and Class 401, Coating Implements With Material Supply, see (4) Note under Class 401, subclass 221.

(3) Note. This, rather than an indented, subclass is the locus for patents to inventions in penholders, per se, which include no claimed detail of the structure for retaining a penpoint. Included in this subclass are patents to penholders having: (a) relatively movable e.g., yieldable, angularly adjustable) handle portions; (b) ink guards; see, however, subclass 443 for an ink guard contacted by the finger during writing to constitute a finger rest, as well; (c) dip gauge attachments. Patents to penholders provided with plural penpoints, but which claim no penpoint-holding detail, are also collected in this subclass. A cross-reference has been placed in this subclass of each patent including novelty in any of the above features but classifiable in a subclass indented hereinbelow because of further novelty in structure conforming to the definition of the indented subclass. It is expected that this procedure will be followed for such patents which issue in the future.
