Claim(s) 1, 2, and 4 is/are rejected under 35 U.S.C. 14(a)(1) as being anticipated by U.S. Patent No. 5,983,576 to Hanser et al. (“Hanser”). Regarding claim 1, Hanser discloses an expandable structure comprising: a main structure 12; a first expansion section 10, the first expansion section expandable outward in a first direction from the main structure; and walls of the first expansion section are formed from a plurality of wall panels 16, the wall panels 16, in a retracted configuration, are storable in a stacked arrangement (see Fig. 8). Regarding claim 2, Hanser discloses that the plurality of wall panels 16, when stacked in the retracted configuration, have planar interior or exterior faces of each wall panel adjacent each other (see Fig. 8). Regarding claim 4, Hanser discloses that the plurality of wall panels 16, in the retracted configuration, are stored in a wall enclosure housing 16-6, the wall enclosure housing having a slot (opening on one end of 16-6 from which panels 16 extend; see Fig. 10) formed therein for passing each of the plurality of wall panels into and out of the wall enclosure housing. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 3, 5, 6, and 14 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hanser. Regarding claim 3, Hanser does not disclose a second expansion section expandable outward in a second direction from the main structure, wherein second expansion section walls are formed from a plurality of second expansion section wall panels that, in a retracted configuration, are storable in a stacked arrangement. It has been held that a mere duplication of parts, such as the duplication of the first expansion section to have a second expansion section with the same parts, has no patentable significance unless a new and unexpected result is produced. A duplication of parts is generally recognized as being within the level of ordinary skill in the art. In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1955). Regarding claim 5, Hanser discloses that a first wall enclosure housing 16-6 is used for a first expansion section 10 side wall of the expansion section, but does not disclose a second wall enclosure housing is used for a second expansion section side wall of the expansion section. It has been held that a mere duplication of parts, such as the duplication of the first expansion section to have a second expansion section with the same parts, has no patentable significance unless a new and unexpected result is produced. A duplication of parts is generally recognized as being within the level of ordinary skill in the art. In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1955). The claims dependent of claim 5 will refer to the same reference numbers for the first and second expansion sections due to the second expansion section having the same parts as the first expansion section. Regarding claim 6, Hanser discloses that the first and second wall enclosure housings 16-6 provide structural support for the main structure. Regarding claim 14, Hanser discloses an expandable structure comprising: a main structure 12; a first expansion section, the first expansion section 10 expandable outward in a first direction from the main structure; wherein: first and second side walls 16, 18 of the first expansion section are formed from a plurality of first and second side wall panels 16-1 to 16-5 and 18-1 to 18-5; the wall panels, in a retracted configuration, are storable in a stacked arrangement (see Fig. 8); first and second wall enclosure housings 16-6, 18-6 holding the plurality of first and second wall panels, respectively, in the retracted configuration. Hanser does not disclose a second expansion section expandable outward in a second direction from the main structure; third and fourth side walls of the second expansion section are formed from a plurality of second expansion section third and fourth side wall panels that, in a retracted configuration, are storable in a stacked arrangement; and third and fourth wall enclosure housings holding the plurality of second expansion section third and fourth wall panels, respectively, in the retracted configuration. It has been held that a mere duplication of parts, such as the duplication of the first expansion section to have a second expansion section with the same parts, has no patentable significance unless a new and unexpected result is produced. A duplication of parts is generally recognized as being within the level of ordinary skill in the art. In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1955). The claims dependent of claim 14 will refer to the same reference numbers for the first and second expansion sections due to the second expansion section having the same parts as the first expansion section. As a result of duplicating the first expansion section, the Hanser discloses a second expansion section 10 expandable outward in a second direction from the main structure; third and fourth side walls 16, 18 of the second expansion section are formed from a plurality of second expansion section third and fourth side wall panels 16-1 to 16-5 and 18-1 to 18-5 that, in a retracted configuration, are storable in a stacked arrangement; and third and fourth wall enclosure housings holding the plurality of second expansion section third and fourth wall panels, respectively, in the retracted configuration. Claim(s) 10, 11, and 18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Angelow in view of Hanser. Regarding claim 10, 11, and 18, Hanser does not disclose actuators or a pair of actuators provided on opposite sides of the wall enclosure housing, the actuators moving wall panels disposed therein between the deployment position and a storage position. Hanser discloses a pair of actuators (Hanser 44; col 4, ln 37-42), the actuators moving wall panels disposed therein between the deployment position and a storage position. It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to combine the expandable structure of Angelow to have a pair of actuators provided on opposite sides of the wall enclosure housing, the actuators moving wall panels disposed therein between the deployment position and a storage position as taught in Hanser with a reasonable expectation of success because it would provide an automatic means deploying and collapsing the expandable section. Moreover it has been held that a mere duplication of parts, such as the duplication of the actuators on sides of the wall, has no patentable significance unless a new and unexpected result is produced. A duplication of parts is generally recognized as being within the level of ordinary skill in the art. In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1955).
