Appeal 2007-0516
Application 10/438,506
1 installing welding) a metal bracket to the interior surface
2 of the drum's head wall, which will hold the 15 shaft
3 upright within the drum.
4 Spec. p. 2 (emphasis added).
5 Applicant further argues (Amended Appeal Br. p. 8) that changing
6 pitch to diameter is mere rephrasing or rewording and that rewording where
7 the meaning stays intact is not new matter. However, the change from pitch
8 to diameter does not keep the meaning intact. The change fundamentally
9 alters the meaning. As the original written description stated in the section
10 titled “Summary of the Invention”:
11 The present invention provides a one-piece conversion
12 device that quickly and easily allows a drum having a
13 flange with one pitch of internal threads (e.g. 2 inches) to
14 be compatible with a motor having a mounting
15 component with a different pitch of external threads (e.g.,
16 1 ½ inches)”
17 Spec. p. 2 (emphasis added). Similarly the original claims referred to
18 different pitch. For example, original Claim 1 in relevant part states:
19 the drum including a top wall having a central
20 opening defined by a flange having internal threads of a
21 certain pitch; . . .
22 the one-piece conversion device, including an
23 annular portion . . .;
24 the annular portion having external threads with a
25 pitch corresponding to the internal threads of the flange;
the annular portion also having internal threads
with a different pitch than the internal threads of the
flange;
26 the annular portion being positioned within the
27 central opening with its external threads engaged with the
28 internal threads of the flange . . . .
29 Amended Appeal Br., p. 13, Claim 1.
