The same
part of an invention appearing in more than one view of
the drawing must always be designated by the same
character, and the same character must never be used to
designate different parts. Reference signs not mentioned
in the description shall not appear in the drawing, and
vice versa.
(g) Symbols, legends. Graphical drawing symbols and other
labeled and labeled representation are used must be
adequately identified in the specification. While
descriptive matter on drawings is not permitted, suitable
legends may be used, or may be required in proper cases,
as in diagrammatic views and flow sheets or to show
materials or where labeled representations are employed to
illustrate conventional elements. Arrows may be required,
in proper cases, to show direction of movement. The
lettering should be as large as, or larger than, the
reference characters.
(h) [Reserved]
(i) Views. The drawing must contain as many figures as may be
necessary to show the invention; the figures should be
consecutively numbered if possible in the order in which
they appear. The figures may be plain, elevation, section,
or perspective views, and detail views of portions of
elements, on a larger scale if necessary, may also be
used. Exploded views, with the separated parts of the same
figure embraced by a bracket, to show the relationship or
order of assembly of various parts are permissible. When
necessary, a view of a large machine or device in its
entirety, may be broken and extended over several sheets
if there is no loss in facility of understanding the view.
Where figures on two or more sheets form in effect a
single complete figure, the figures on the several sheets
should be so arranged that the complete figure can be
understood by laying the drawing sheets adjacent to one
another. The arrangement should be such that no part of
any of the figures appearing on the various sheets are
concealed and that the complete figure can be understood
even though spaces will occur in the complete figure
because of the margins on the drawing sheets. The plane
upon which a sectional view is taken should be indicated
on the general view by a broken line, the ends of which
should be designated by numerals corresponding to the
figure number of the sectional view and have arrows
applied to indicate the direction in which the view is
taken. A moved position may be shown by a broken line
superimposed upon a suitable figure if this can be done
without crowding, otherwise a separate figure must be used
for this purpose. Modified forms of construction can only
be shown in separate figures. Views should not be
connected by projection lines nor should center lines be
used.
(j) Arrangement of views. All views on the same sheet should
stand in the same direction and, if possible, stand so
that they can be read with the sheet held in an upright
position. If views longer than the width of the sheet are
necessary for the clearest illustration of the invention,
the sheet may be turned on its side so that the top of the
sheet with the appropriate top margin is on the right-hand
side. One figure must not be placed upon another or within
the outline of another.
(k) Figure for Official Gazette. The drawing should, as far as
possible, be so planned that one of the views will be
suitable for publication in the Official Gazette as the
illustration of the invention.
(l) Extraneous matter. Identifying indicia (such as the
attorney's docket number, inventor's name, number of
sheets, etc.) not to exceed 2 3/4 inches (7.0 cm.) in width
may be placed in a centered location between the side
edges within three-fourths inch (19.1 mm.) of the top
edge. Authorized security markings may be placed on the
drawings provided they are outside the illustrations and
are removed when the material is declassified. Other
extraneous matter will not be permitted upon the face of a
drawing.
(m) Transmission of drawings. Drawings transmitted to the
Office should be sent flat, protected by a sheet of heavy
binder's board, or may be rolled for transmission in a
suitable mailing tube; but must never be folded. If
received creased or mutilated, new drawings will be
required. (See 1.152 for design drawing, 1.165 for plant
drawings, and 1.174 for reissue drawings.)
The requirements relating to drawings are strictly
enforced, but a drawing not complying with all of the
regulations may be accepted for purpose of examination, and
correction or a new drawing will be required later.
