Opinion

MARKEY, Chief Judge.

This appeal is from the decision of the Board of Appeals affirming the rejection of claims 1-8, 11-30, 32, 33 and 34, all the remaining claims, of appellant’s application serial No. 18,727, filed March 11, 1970, for reissue of patent No. 3,391,392, issued July 2, 1968 on an application filed October 18, 1965, for “Method and Apparatus for Pattern Data Processing.” We affirm.

The Invention

The invention relates to grading garment patterns and more particularly to a system that “automatically produces data for patterns of all the desired sizes from a single reference pattern.” According to the application:

A reference garment pattern is digitized and with grading control data and digital data processing methods is converted into data indicative of additional size patterns. Digital comput[1386]*1386er means are provided for selectively changing the boundaries of the reference pattern according to predetermined grade instructions from grading control data to produce positional data indicative of the additional size patterns.

Figs. 1 and 2, reproduced below, illustrate, respectively, a reference pattern to be graded to provide corresponding patterns for additional sizes and “a schematic block diagram illustrating a principal aspect of the automatic grading method of the invention”:

The pattern 11 may be a part of a dress pattern of a reference size such as 12 from which corresponding parts for a selected range of sizes such as 6, 8, 10, 14, 16 and 18 may be produced. The pattern 11 has various control points, such as point 12, which may be marked by notches and located at corners and other key positions of the pattern 11, The points are utilized in the invention as points from which dimensional changes predetermined by the designer are applied to locate corresponding offset points on the patterns of the additional sizes.

As to Fig. 2, the application states:

[T]he reference pattern 11 of FIG. 1 is initially placed on a pattern tracer 21 which is an automatic curve follower to be described later. The tracer 21 follows the boundary of the pattern 11 including the control points 12 and 13 and provides positional incremental data based on X and Y coordinate axes to a position data converter 22. The incremental data is converted into Cartesian point data by the data converter 22 according to predetermined sequence recognition rules and, with the X-Y positional data from a significant point computer 23, is fed to a control point computer 24. The significant point computer 23 selects the Cartesian positional data from converter 22 according to maximum and minimum deviation criteria relative to the X and Y coordinate axes to provide significant point positional data indicative of the reference pattern. The control point computer 24, respon[1387]*1387sive to the Cartesian positional data from the converter 22 and the significant point data from the computer 23, computes control points. A grade computer 25 computes offset intermediate point positional data for the selected additional size patterns in accordance with the computed intermediate points for the reference pattern 11. The graded positional data from the control point computer 24 are fed to a drive control 29 which drives a pattern plotter 27 to provide a graphical display of the additional size patterns 28.

No programs for the computers are set forth in the application.

At the end of the specification, appellant states that the “preferred embodiment” which he shows and describes is “susceptible to changes in form and detail” and that:

[Although the use of an incremental plotter with an incremental pattern tracer particularly enhances the operation of the system, it would be well within the knowledge of those skilled in the art to utilize other forms of plotters and curve followers, including manual curve followers * * *.

The particular operation of pattern tracer 21 and position data converter 22 of Fig. 2 is irrelevant to the basis on which we determine the appeal. The adequacy of disclosure of the pattern plotter 27 is unquestioned.

The function of the significant point computer is disclosed with respect to Fig. 15:

The figure shows a portion 101 representative of the pattern 11 of Fig. 2. The input to the significant point computer 23 (Fig. 2) from the position data converter is a series of raw boundary data points such as 102 on line 101. The significant data computer analyzes these data points “to provide significant points [1388]*1388such as illustrated in Fig. 15 wherein significant points Pi0 Pisi P¡sz and Pm are shown.” The primary significant points Pi0 and Pin are first established. Then the secondary points Pisi and PiS2 are determined.

The control point computer determines, from raw boundary data from position converter 22 and significant point data from the computer 23, the location, of control points represented on the pattern 11 by notches as indicated in Fig. 18:

According to the application:

In the beginning, a maximum spacing test is made in which two significant points are found which are within the maximum distance allowable (kmax). After two significant points are found within the kmax then an additional spacing test is conducted in which all points within the distance of the kmax are established. If three, or more significant points are within the kmax, then a notch is tentatively designated and a further series of tests is conducted. A base line test is conducted to find two end points 112 and 113 which represent the base line of the notch, from which is determined the midpoint M. An apex test finds the apex A, after which a line is determined from M to A as illustrated * *

Some further discussion of the control point computer operation is given with respect to figures of the drawing designated “flow charts.”

The function of the grade computer is best discussed in connection with Fig. 9:

There P0 and Pf represent control points on the pattern 11 established by the control point computer and P„' and P/ are offset points established by the grade computer by means of offset vectors AP0 and AP7 which constitute grade control data furnished thereto at 26 in Fig. 2. P, represents an arbitrary intermediate point on the pattern and P¡' a corresponding intermediate offset point on the graded pattern determined by the grade computer on the basis of the triangles P0 Pi Pt and P0' Pi' P/ being similar and their corresponding sides proportional. The computer determines a plurality of such intermediate offset points between P0' and Pf' to define the graded pattern.

Claims 7 and 14 are illustrative:

7. A system for grading a reference pattern to produce additional size patterns comprising:

a pattern tracer for converting the reference pattern boundary into incremental positional data based on X and Y coordinate axes;
a position data converter responsive to said tracer for converting said positional data into Cartesian point data;
[1389]*1389a significant point computer responsive to said Cartesian point data and slope criteria relative to said X and Y coordinate axes to produce significant point data;
