Opinion

RICH, Judge.

This appeal is from the decision of the Patent Office Board of Appeals affirming the rejection of claims 28-31 of application serial No. 862,597, filed August 27, 1969, entitled “Apparatus for Woven Screen Memory Devices,” on the ground of “new matter” added by amendment, under 35 U.S.C. § 132. The application is for reissue of appellants’ U. S. patent No. 3,377,581, issued April 9, 1968. Claims 1-27 stand allowed. We reverse.

The Invention Described In The Reissue Application As Filed

The invention is a woven screen magnetic memory structure for use in computers and data processing systems. Claim 6 of the original patent, held allowable on reissue, is as follows:

6. A woven screen structure suitable for the deposition of remanent magnetic material thereon to provide a memory device comprising:

a plurality of substrate wires and a plurality of control wires interwoven to define a plurality of individual cells, each comprising at least one mesh of the interwoven substrate wires having selected control wires threaded therethrough; and
a plurality of idle wires interspersed with the control wires between adjacent substrate wires bounding a particular individual cell for determining the relative position of the control wires therein. [Emphasis ours.]

As explained by the introductory portion of the specification, which we designate [A]:

In accordance with the present invention, machine woven planes are provided by simultaneously weaving bare substrate wires and insulated conductors on an automatic or manual loom [659]*659in a predetermined matrix, after which the resulting planes may be chemically processed to provide the finished magnetic screen memory devices. [Emphasis ours.]

A typical cell configuration of the woven screen memory structure is shown by the following diagrammatic figure, on an enlarged scale, from the present application and original patent:

A grid of substrate wires 32 forms the square storage cell, the wires being coated with a magnetic material. These substrate wires are interwoven with control wires, variously designated as sense wires 34, Y-drive wires 36, X-drive wires 38, and inhibit wires 40, which are shown interwoven to form the depicted portion of the memory matrix. The issue here centers specifically on the “dummy” or “idle” wires 42 which “serve to provide the desired spacing between particular wires of the matrix and also may serve to control the threading of particular cells by the respective control wires.”

The nature of the dummy wires appears from the following explanation, which appellants rely upon, and which we designate [B]:

In the weaving of the desired memory planes on automatic power looms, it has been found that the insulated conductors have a tendency to slip from their initial position in the mesh of the substrate wires. In accordance with an aspect of the present invention, therefore, additional conductors, which may be referred to as “dummy” or “idle” conductors, are inserted at appropriate intervals during the weaving process to increase the packing of the conductors placed between adjacent substrate wires and thus affix the insulated conductors in a predetermined position relative thereto. [Emphasis ours.]

Finally, the nature of the substrate wires and the control wires is explained by the following quotation from the specification, which we designate [C]:

The substrate wires 32 may advantageously be bare copper wires which are ultimately coated with a magnetic layer to define the magnetic flux paths of a given storage cell. However, in the various embodiments of the present invention the substrate wires are not limited to bare copper wires but may be any metallic wires [660]*660on which a suitable magnetic coating may be deposited. Thus, the substrate wires 32 may, for example, comprise wires of another metal than copper, or they may even be insulated wires or plastic filaments having an outer surface which is suitably treated to permit the deposition of a magnetic coating thereon. The control wires are electrical conductors which serve to carry various currents employed in the operation of devices produced in accordance with the present invention. In general, the control wires are insulated to provide the desired electrical isolation of the various wires. [Emphasis ours.]

The Prosecution

The instant application seeks to reissue entirely the original patent and add thereto eight new claims. Thus, the original patent, which contained claims 1-23, is incorporated without change in the reissue application which, as originally filed, added only claims 24-27, copied from a Bohannon, Jr., patent1 to provoke an interference. These copied claims described the dummy wires as “non-eonductive fibers” and were rejected by the examiner as lacking support in the original disclosure under 35 U.S.C. § 112 and as containing new matter under 35 U.S.C. § 132, the examiner being of the view that appellants’ dummy wires were described in their specification as being “conductive,” rather than “non-conductive” as claimed. Appellants vigorously traversed the rejection of claims 24-27 and attempted to show how their specification supported the “non-conduc-five” limitation, but, in the alternative, amended their application in accordance with the second sentence of Rule 205(a) 2 to add claims 28-31, which are identical to copied claims 24-27 except that the adjective “non-conductive” is omitted and the dummy wires described merely as “fibers.” Representative of the appealed claims is claim 28:

28. A magnetic memory matrix in the form of a woven fabric comprising:
a plurality of parallel magnetizable conductive strands capable of assuming stable states of remanence;
a first plurality of fibers in-terspaced between the magnetizable strands;
a plurality of parallel control conductors arranged so that the control conductors cross the magnetizable strands; and
a second plurality of fibers inter-spaced between the control conductors and interwoven with the first fibers and the magnetizable strands such that the individual control conductors and magnetizable strands are maintained in predetermined relative positions. [Emphasis ours.]

The examiner, however, rejected amended claims 28-31 as containing new matter under 35 U.S.C. § 132.3 Appellants appealed the rejection of all eight claims to the Board of Appeals.

The Board Decision and the Issue

The board reversed the rejection of copied claims 24-27, agreeing with appellants that their specification support[661]*661ed the claim limitation to “non-conductive fibers,” giving only the following reasons:
