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) 1-3, 7-10, 12-14, and 22-23 are rejected under 35 U.S.C. 103 as being unpatentable over PG Pub. US 2014/0262084 – Fleischman in view of PG Pub US 2014/0346811 A1 – Zaluzec et al., hereinafter Zaluzec.
Regarding claim 1.
Fleischman discloses a motorized window treatment comprising:
a roller tube (40, fig 2) that comprises a first tube comprising metal (Paragraph [0048]; The tube 40, 40' may be formed from aluminum or an aluminum alloy); and
a covering material (26, fig 2) that is attached to the roller tube (at 82, fig 3), the covering material operable between a raised position and a lowered position via rotation of the roller tube by a motor drive unit (Compare 12, 14, and 16, fig 1).
Fleischman does not disclose a second tube that is concentrically arranged around the first tube, the second tube comprising a plurality of successively applied layers of carbon fiber, wherein the plurality of layers of carbon fiber comprise at least three layers and wherein carbon fibers of an innermost layer and carbon fibers of an outermost layer have a same alignment relative to a longitudinal axis defined by the first tube, and wherein the second tube is bonded to the first tube.
However, Zaluzec teaches a first tube (20, fig 1b) comprising metal (Paragraph [0044]; Beam member 20 may be formed from steel, aluminum or any suitable material) and a second tube (30, 40, 50, fig 1b) that is concentrically arranged around the first tube (See fig 1b), the second tube comprising a plurality of successively applied layers of carbon fiber (Paragraph [0043]; FIGS. 1A and 1B show one embodiment of a vehicle beam member 20 which may be stiffened by bonding of one or more layers of carbon fiber (CF) prepregs to exterior surface(s) of the member 20.), wherein the plurality of layers of carbon fiber comprise at least three layers (30, 40, 50, fig 1a) and wherein carbon fibers of an innermost layer and carbon fibers of an outermost layer have a same alignment relative to a longitudinal axis defined by the first tube (Paragraph [0050]; Other common fiber directions with respect to a defined base member axis (or with respect to the fiber orientation of an adjacent prepreg) are 0, 45, 60 and 90 degrees. (Examiner notes that a 3-layer composite with a 90 degree offset would result in fibers of an innermost layer and carbon fibers of an outermost layer have a same alignment relative to a longitudinal axis defined by the first tube, as claimed.)), and wherein the second tube is bonded to the first tube (Paragraph [0043]; FIGS. 1A and 1B show … bonding of one or more layers of carbon fiber (CF) prepregs to exterior surface(s) of the member 20.).
It would have been obvious to a person having ordinary skill in the art, with a reasonable expectation of success, before the effective filing date of the claimed invention to modify the window treatment of Fleischman with the composite tube of Zaluzec. One of ordinary skill in the art would have been motivated to make this modification in order to optimize the strength and/or stiffness of the roller tube for the desired application (See fig 9 of Zaluzec).
Regarding claim 2.
The combination of Fleischman and Zaluzec teaches all limitations of claim 1.
The combination (in Zaluzec) further teaches the plurality of layers of carbon fiber are layers of wound carbon fiber filament (Paragraph [0029]; Prepregs are available in which all of the carbon fibers in the prepreg are oriented predominantly along or parallel to a single axis. Such prepregs are commonly known as "unidirectional prepregs".).
Regarding claim 3.
The combination of Fleischman and Zaluzec teaches all limitations of claim 1.
The combination (in Zaluzec) further teaches the roller tube is a second tube is additively constructed on first tube (Paragraph [0022]; It has been found that the strength and stiffness of a beam member may be enhanced by wrapping a carbon fiber prepreg around a beam member and bonding the prepreg to the beam member).
Regarding claim 7.
The combination of Fleischman and Zaluzec teaches all limitations of claim 3.
The combination (in Zaluzec) further teaches the first tube is aluminum or steel (Paragraph [0044]; Beam member 20 may be formed from steel, aluminum or any suitable material).
Regarding claim 8.
The combination of Fleischman and Zaluzec teaches all limitations of claim 7.
The combination (in Zaluzec) further teaches the second tube (30,40,50, fig 1b) is attached to the first tube by curing the plurality of layers of carbon fiber (Paragraph [0028]; Various embodiments of the prepregs described herein may be bonded directly to associated exterior surfaces of the beam member (or portions thereof) by curing of the adhesive matrix in which the carbon fibers are encased.).
Regarding claim 9.
The combination of Fleischman and Zaluzec teaches all limitations of claim 8.
The combination (in Zaluzec) further teaches the plurality of layers of carbon fiber are wound carbon fiber filament (Paragraph [0029]; Prepregs are available in which all of the carbon fibers in the prepreg are oriented predominantly along or parallel to a single axis. … the prepreg material may be in the form of a thin tape which may be wound around the beam member as desired).
Regarding claim 10.
The combination of Fleischman and Zaluzec teaches all limitations of claim 8.
The combination (in Zaluzec) further teaches the plurality of layers of carbon fiber are carbon fiber fabric (Paragraph [0029]; prepregs are available in which the fibers or bundles of fibers are woven into a fabric structure having interlaced or interlocking arrangement).
Regarding claim 12.

Regarding claim 13.
The combination of Fleischman and Zaluzec teaches all limitations of claim 1.
The combination (in Zaluzec) further teaches fibers of at least one layer of the plurality of layers of carbon fiber are oriented perpendicular to the longitudinal axis (Paragraph [0050]; common fiber directions with respect to a defined base member axis (or with respect to the fiber orientation of an adjacent prepreg) are 0, 45, 60 and 90 degrees.) defined by the first tube to enhance cracking resistance.
Regarding claim 14.
The combination of Fleischman and Zaluzec teaches all limitations of claim 1.
The combination does not explicitly teach the fibers of the innermost layer and the fibers of the outermost layer are not angularly offset relative to the longitudinal axis defined by the first tube.
However, Zaluzec describes an experiment involving the bonding of twenty-eight successive layers of the prepreg to the aluminum beam member. (Paragraph [0063]; Successive layers or sheets of 0/90 degree fiber composite prepreg (wherein each layer is formed from a series of alternating 0.degree. and 90.degree. plies) were bonded to the beam member). This resulted in two sets of 14 layers of parallel orientation of fibers having a same alignment relative to a longitudinal axis defined by the first tube.
It would have been therefore obvious to a person having ordinary skill in the art, with a reasonable expectation of success, before the effective filing date of the claimed invention to further modify the combination of Fleischman and Zaluzec to have the fibers of the innermost layer and the fibers of the outermost layer are not angularly offset relative to the longitudinal axis defined by the first tube.
One of ordinary skill in the art would have been motivated to make this modification in order to optimize the strength and/or stiffness of the roller tube for the desired application (See fig 9 of Zaluzec.).

Claim(s) 4, 15, 19-20, and 25-27 are rejected under 35 U.S.C. 103 as being unpatentable over French Patent 2872196 – Benoin in view of Zaluzec.
Regarding claim 4.
Benoin discloses a motorized window treatment (1, fig 1) comprising:
a roller tube comprising a plurality of layers of carbon fiber (13, fig 1 – also see attached translation excerpt inserted below) comprising an innermost layer of carbon fiber material and an outermost layer of carbon fiber material (examiner notes that any number of layers (see attached translation excerpt inserted below) must at least have an innermost layer and an outermost layer as dictated by the geometry of the part.); and
a covering material (See page 1, lines 4-8) that is attached to the roller tube, the covering material operable between a raised position and a lowered position via rotation of the roller tube by a motor drive unit (See page 1, lines 4-8).
Benoin does not explicitly disclose successively applied layers of carbon fiber, comprising an intermediate layer of carbon fiber material bonded to the innermost layer, and an outermost layer of carbon fiber material that surrounds the intermediate layer and the innermost layer, wherein the innermost layer and the outermost layer are each oriented such that fibers of the respective layers have a same alignment relative to a longitudinal axis of the roller tube, and wherein fibers of the intermediate layer have an alignment relative to the longitudinal axis of the roller tube that is different from the alignment of the innermost layer and the outermost layer.
However, Zaluzec teaches a plurality of successively applied layers of carbon fiber (30, 40, 50, figs 1a and 1b), comprising an innermost layer of carbon fiber material (30, fig 1a), an intermediate layer of carbon fiber material (40, fig 1a) bonded to the innermost layer, and an outermost layer of carbon fiber material (50, fig 1a) that surrounds the intermediate layer and the innermost layer (See fig 1a), wherein the innermost layer and the outermost layer are each oriented such that fibers of the respective layers have a same alignment relative to a longitudinal axis of the roller tube (Paragraph [0050]; Other common fiber directions with respect to a defined base member axis (or with respect to the fiber orientation of an adjacent prepreg) are 0, 45, 60 and 90 degrees. (Examiner notes that a 3-layer composite with a 90 degree offset would result in fibers of an innermost layer and carbon fibers of an outermost layer have a same alignment relative to a longitudinal axis defined by the first tube, as claimed.)), and wherein fibers of the intermediate layer have an alignment relative to the longitudinal axis of the roller tube that is different from the alignment of the innermost layer and the outermost layer (Paragraph [0050]; Other common fiber directions with respect to a defined base member axis (or with respect to the fiber orientation of an adjacent prepreg) are 0, 45, 60 and 90 degrees. (Examiner notes that a 3-layer composite with a 90 degree offset would result in fibers of an intermediate layer have an alignment relative to the longitudinal axis of the roller tube that is different from the alignment of the innermost layer and the outermost layer, as claimed.)).
It would have been obvious to a person having ordinary skill in the art, with a reasonable expectation of success, before the effective filing date of the claimed invention to modify the window treatment of Benoin with the composite tube of Zaluzec. One of ordinary skill in the art would have been motivated to make this modification in order to optimize the strength and/or stiffness of the roller tube for the desired application (See fig 9 of Zaluzec).

Regarding claim 15.
The combination of Benoin and Zaluzec teaches all elements of claim 4.
Benoin further discloses the-innermost layer further comprises a plurality of splines that extend radially from a surface of the innermost layer that is opposite relative to a surface of the innermost layer that is bonded to the intermediate layer (Page 3, lines 20-21; des rainures paralleles et des cannelures complemetaires sur le moteur).
Regarding claim 19.
The combination of Benoin and Zaluzec teaches all elements of claim 4.
Benoin further discloses the plurality of layers of carbon fiber is a wound carbon fiber filament (Page 6, line 23-Page 7, line 5; The housing is made of composite material and is obtained by a pultrusion process. In this process, reinforcements in the form of yarns … made of … carbon fibers).
Regarding claim 20.
The combination of Benoin and Zaluzec teaches all elements of claim 4.
Benoin further discloses the plurality of layers of carbon fiber is a carbon fiber fabric (Page 6, line 23-Page 7, line 5; The housing is made of composite material and is obtained by a pultrusion process. In this process, reinforcements in the form of … woven or non-woven mats … made of … carbon fibers).
Regarding claim 25.
The combination of Benoin and Zaluzec teaches all elements of claim 4.
The combination does not explicitly teach the fibers of the innermost layer and the fibers of the outermost layer are not angularly offset relative to the longitudinal axis defined by the first tube.
However, Zaluzec describes an experiment involving the bonding of twenty-eight successive layers of the prepreg to the aluminum beam member. (Paragraph [0063]; Successive layers or sheets of 0/90 degree fiber composite prepreg (wherein each layer is formed from a series of alternating 0.degree. and 90.degree. plies) were bonded to the beam member). This resulted in two sets of 14 layers of parallel orientation of fibers having a same alignment relative to a longitudinal axis defined by the first tube.
It would have been therefore obvious to a person having ordinary skill in the art, with a reasonable expectation of success, before the effective filing date of the claimed invention to further modify the combination of Fleischman and Zaluzec to have the fibers of the innermost layer and the fibers of the outermost layer are not angularly offset relative to the longitudinal axis defined by the first tube.
One of ordinary skill in the art would have been motivated to make this modification in order to optimize the strength and/or stiffness of the roller tube for the desired application (See fig 9 of Zaluzec.).
Regarding claim 26.
The combination of Benoin and Zaluzec teaches all elements of claim 4.
The combination (in Zaluzec) further teaches fibers of adjacent layers of the plurality of layers of carbon fiber are angularly offset from one another (Paragraph [0005]; A fiber orientation of the second prepreg is arranged at a non-zero angle with respect to a fiber orientation of the first prepreg.).
Regarding claim 27.

Claim(s) 24 is/are rejected under 35 U.S.C. 103 as being unpatentable over the combination of Fleischman and Zaluzec as applied above, and further in view of Benoin.
Regarding claim 24.
The combination of Fleischman and Zaluzec teaches all limitations of claim 23.
The combination does not teach the first tube further comprises a plurality of splines that extend radially from the inner surface into the void, and wherein the plurality of splines are oriented along the longitudinal axis of the first tube.
However, Benoin teaches the first tube further comprises a plurality of splines that extend radially from the inner surface into the void, and wherein the plurality of splines are oriented along the longitudinal axis of the first tube (Page 3, lines 20-21; des rainures paralleles et des cannelures complemetaires sur le moteur).
It would have been obvious to a person having ordinary skill in the art, with a reasonable expectation of success, before the effective filing date of the claimed invention to modify the combination of Fleischman and Zaluzec with the splines of Benoin. One of ordinary skill in the art would have been motivated to make this modification in order to yield the predictable result of allowing interface with a different type of motor drive adapter as suggested in Page 3, lines 20-21 of Benoin “des rainures paralleles et des cannelures complemetaires sur le moteur”, to make use of parts on hand.
