As to claim 11, Mashburn teaches the trash can of Claim 10, wherein the trim and the lid are configured to rotate around a shared pivot axis(col. 9: lines 25-41). As to claim 14, Mashburn teaches a trash can assembly (col. 2: lines 53 – col. 3: lines 60) comprising: a body comprising a front wall, a rear wall, a base, an upper opening, and an upper lip and a lid that is rotatable between a closed position and an open position(col. 5: lines 58 – col. 6: lines 11 & col. 9: lines 25-41 wherein a trash can has a body with walls, a base and a lid that is rotatable between a closed position and an open position); a trim that is rotatable between a lower resting position and an upper retained position, the trim comprising an exterior front surface with a top edge and a bottom edge, the exterior front surface being flat between the top and bottom edges, wherein with the lid in the closed position and the trim in the lower resting position(col. 5: lines 58-64 & col. 13: lines 15-37): the exterior front surface is farther frontward than any other portion of the trim; and the top edge of the exterior front surface is above the upper lip of the body and the bottom edge of the exterior front surface is below the upper lip of the body and a retainer configured to engage to maintain the trim in the upper retained position, the retainer comprising a first cam connected to the trim and a second cam connected to the body, the first and second cams located rearward of the rear wall(col. 5: lines 65 – col. 6: lines 11, col. 6: lines 50 -col. 7: lines 4 & col. 13: lines 15-37 wherein apparatus and method are taught for trash can system which has surfaces, trims and retaining mechanism for the system). As to claim 19, Mashburn teaches the trash can assembly of Claim 14, further comprising a liner support member supported by the body and configured to support the trash bag at least partly within the body(col. 3: lines 49-60) As to claim 20, Mashburn teaches the trash can assembly of Claim 14, wherein the trash can assembly is configured receive a trash bag in the body and to maintain a mouth of the trash bag in a position horizontally inward from the exterior front surface of the trim(col. 7: lines 44-63). Claim Rejections - 35 USC § 103 4. The following is a quotation of 35 U.S.C. 103(a) which forms the basis for all obviousness rejections set forth in this Office action: (a) A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102 of this title, 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 negatived by the manner in which the invention was made. 5. Claims 12-13, 15-18 are rejected under 35 U.S.C. 103(a) as being unpatentable over USPN 9,309,048 to Mashburn, and in view of USPN 3,942,430 to Day. As to claim 12, Mashburn teaches the trash can of Claim 10. Mashburn does not teach an apparatus wherein the housing extends rearwardly from the rear wall a distance of less than or equal to 1/5th of the distance between the outside surface of the rear wall and the front-most portion of the front wall. Day teaches a flexible/movable housing for a trash processing equipment(col. 3: lines 5-58). Thus, it would have been obvious to one of ordinary skill in the art at the time of the invention was made to implement the teachings of Day into Mashburn since Mashburn suggests a trash can and Day suggests the beneficial use of a flexible/movable housing for a trash processing equipment in the analogous art of trash processing technology. The motivation for this comes from the fact that Day teaches a flexible/movable housing for a trash processing equipment which can be readily modified to produce an invention as claimed in claim 12. As to claim 13, Mashburn in view of day teaches a flexible/movable housing for a trash processing equipment which can be readily modified to produce an invention as claimed in claim 13 by a person of ordinary skill in the art. As to claim 15, Mashburn in view of day teaches the trash can assembly of Claim 14, wherein the first cam comprises a tooth and the second cam comprises a ramp along which the tooth slides(Day col. 9: lines 48-64). As to claim 16, Mashburn in view of day teaches the trash can assembly of Claim 15, wherein the second cam further comprises a recess that receives the tooth(Day col. 9: lines 48-64). As to claims 17 and 18, Mashburn in view of day teaches the trash can assembly of Claim 14. It would be obvious for a person of ordinary skill in the art to modify the teaching of Mashburn in view of day to produce the invention as claimed in those claims because Mashburn in view of day teaches a movable lid/trim (Mashburn col. 10: lines 28-39) and cam (Day col. 9: lines 48-64) for a trash processing equipment. Conclusion 6. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. USPN 6,837,393 to Kuo discloses a garbage can system. 7.
