(a) A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 2, 4, 7 and 12-13 are rejected under pre-AIA  35 U.S.C. 103(a) as being unpatentable over Klein, US 2007/0107325 in view of Morgan et al., US 2003/0079425.
Regarding claims 2 and 12:
Klein discloses a wall assembly, comprising:
a ceiling structure (4);
a floor structure (2) positioned opposite the ceiling structure; a header track attached to the ceiling structure;
a bottom track (8) attached to the floor structure, the bottom track including a first flange and a second flange extending from opposite edges of a web;
at least one stud (abstract) extending in a vertical direction between the bottom track and the header track;
a wallboard (6) attached to the at least one stud, the wallboard having a lower edge relatively closer to the floor structure and an upper edge relatively further from the floor structure, wherein a bottom wall gap is defined between the lower edge of the wallboard, the first flange of the bottom track, and the floor structure;
an elongate, compressible mastic component (46) received within the bottom wall gap to block passage of smoke or sound through the bottom wall gap, the component comprising a rectangular cross-sectional profile extending between a first end and a second end, the rectangular cross-sectional profile having a first side and a second side, the first side and the second side meeting at a first edge, a third side opposite the first side, and a fourth side opposite the second side, the first side and the fourth side meeting at a second edge, the rectangular cross-sectional profile extending from the first end to the second end;
wherein the elongate component is positioned such that the first side faces the first flange of the bottom track;
wherein the second side of the elongate component contacts the lower edge of the wallboard; and
wherein the fourth side of the elongate component contacts the floor structure.
Klein does not expressly disclose wherein the elongate compressible component is a foam component.
Morgan discloses a wall assembly wherein a gap between a building surface and a wallboard (18) has an elongate, compressible, rectangular foam component received therein.
At the time the invention was filed, it would have been obvious to a person of ordinary skill to substitute the foam component as suggested by Morgan for the mastic component of Klein in order to allow cyclic movement of the wallboards while also preventing heat and smoke from going through the gap. Further, Morgan suggests wherein foam, rubber, polystyrene, mineral wool and other flexible materials that allow for cyclical movement while preventing heat and smoke from entering are interchangeable without yielding any extraordinary or unexpected results in the application of filling the gap between a building surface and a wallboard (para. 0030 of Morgan).
Regarding claims 4 and 13:
Morgan discloses wherein the compressible foam component is configured to create a fire rated joint (para. 0002 of Morgan).
Regarding claim 7:
Morgan discloses wherein the first side comprises a same length as the second side.
Claims 3, 6, 14-17 and 19 are rejected under pre-AIA  35 U.S.C. 103(a) as being unpatentable over Klein, US 2007/0107325 in view of Morgan et al., US 2003/0079425 further in view of Schlappa, US 5,968,615.
Regarding claims 3 and 19:
Morgan discloses a compressible foam component but does not expressly disclose wherein it is open or closed cell.
Schlappa discloses wherein a construction element seal wherein the seal is of closed-cell foam or open cell foam (col. 3, ll. 6-7).
At the time the invention was filed, it would have been obvious to use open or closed cell foam for the unspecified foam of Klein in view of Morgan, as both types of foam can provide effective barrier with sufficient compressibility.
Regarding claims 6, 14-15 and 17:
Morgan does not expressly disclose wherein the foam is coated with a moisture resistant sealant and is fire-resistant polyurethane foam.
Schlappa discloses a compressible foam sealant that has an impervious outer skin (8) that is moisture resistant, is polyurethane foam and is fire-resistant (1st paragraph, 39th paragraph of the detailed description).
At the time of the invention, it would have been obvious to a person of ordinary skill in the art to substitute the compressible foam component of Schlappa for that of Morgan in order to create seals between the building surfaces (background of Schlappa).
Regarding claim 16:
Klein in view of Morgan does not expressly disclose wherein a thickness of the wallboard is larger than a width of the second or fourth side.
Schlappa discloses wherein a thickness of board is larger than a width of the second or fourth sides of the foam.
At the time of the invention, it would have been obvious to a person of ordinary skill to make the foam of the relative width as suggested by Schlappa for the component of Klein in view of Morgan in order to enclose and protect the component within the gap.
Claims 8-11 and 20 are rejected under pre-AIA  35 U.S.C. 103(a) as being unpatentable over Klein, US 2007/0107325 in view of Morgan et al., US 2003/0079425 further in view of Groshong, US 4,598,516.
Regarding claims 8-11 and 20:
Klein in view of Morgan does not expressly disclose a tape.
Groshong discloses a partition assembly with a linear wall gap, wherein a tape (276) is applied over the gap, a first portion of the tape overlying the gap and a second portion of the tape coupled with a wall board (30).
At the time the invention was filed, it would have been obvious to a person of ordinary skill in the art to provide a tape as suggested by Groshon atop the foam of Klein in view of Morgan in order to provide a finished surface for the wall board and to provide protection and concealment over the gap.
Claims 5 and 18 are rejected under pre-AIA  35 U.S.C. 103(a) as being unpatentable over Klein, US 2007/0107325 in view of Morgan et al., US 2003/0079425 further in view of Schouren et al., US 2010/0018142.
Regarding claims 5 and 18:
Klein in view of Morgan does not expressly disclose wherein the elongate, foam component it coated with intumescent material.
Schouren discloses a fire retardant composite that is an intumescent coating applied to a foam (para. 0006).
Before the effective filing date of the invention, it would have been obvious to a person of ordinary skill it coat the elongate, foam component of Klein in view of Morgan with an intumescent layer in order to provide a sealing fire stop (background of Schouren).
