Patentability shall not be negated by the manner in which the invention was made. Claim(s) 8-9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ojeda (US PGPub No. 2014/0328671). Ojeda teaches: limitations from claim 8, a fan (FIG. 5 for example) comprising: a fan housing (12) having a length, height and width; a main outlet (24, 26) having a length (from 38-36), height and width (clearly seen in FIG. 7 at 26), where the main outlet extends vertically along the height of the fan housing, where the width of the main outlet is less than half the width of the fan housing (Ojeda appears to show, in FIG. 4, at least a portion of the outlet with a width less than a width of the housing 102…but does not expressly disclose a relationship between the outlet width and the housing width. However, it has been held that, where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentably distinct from the prior art device; see MPEP 2144.04 Section IV.A); a blower (42) positioned within the fan housing for generating airflow (paragraph 23), where the blower includes at least one or more blades (see paragraph 23, “axial fan, transverse blower…”; unlabeled blades can also be seen in FIG. 6 at numeral 42) and a motor (paragraph 23, “motor”); and a blower housing (as seen in FIG. 5-6 forming the plenum 44 for example) positioned within the fan housing, where the blower housing includes a blower outlet positioned within a lower portion of the main outlet (see annotated FIG. 5 below); PNG media_image1.png 633 476 media_image1.png Greyscale PNG media_image6.png 663 396 media_image6.png Greyscale limitations from claim 9, where an air duct chamber (plenum 44) is formed between the blower outlet and the main outlet (see FIG. 5); Claim(s) 8-9 and 14 is/are rejected under 35 U.S.C. 103 as being unpatentable over Lasko et al (US PGPub No. 2005/0031448). Lasko teaches: limitations from claim 8, a fan (100) comprising: a fan housing (102) having a length, height and width (FIG. 4); a main outlet (112) having a length, height and width (clearly seen in FIG. 4A-B at 112, 136), where the main outlet extends vertically along the height of the fan housing (FIG. 4A), where the width of the main outlet is less than half the width of the fan housing (Lasko appears to show, in FIG. 4A, an outlet with close to or less than a width of the housing 102…but does not expressly disclose a relationship between the outlet width and the housing width. However, it has been held that, where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentably distinct from the prior art device; see MPEP 2144.04 Section IV.A); a blower (106) positioned within the fan housing for generating airflow (paragraph 28), where the blower includes at least one or more blades (see impellers 120a-b which include blades, see also FIG. 4B) and a motor (116); and a blower housing (122) positioned within the fan housing, where the blower housing includes a blower outlet (~126) positioned within a lower portion of the main outlet (see annotated FIG. 4); PNG media_image7.png 778 484 media_image7.png Greyscale limitations from claim 9, wherein an air duct chamber (plenum 44) is formed between the blower outlet and the main outlet (see FIG. 5); limitations from claim 14, where the air duct (132, 134) includes an interior wall positioned rearward of the main outlet (~102A), and where the fan further includes a remote control (paragraph 45 teaching a remote control and control assembly 170) that removably attaches to the interior wall; Claim(s) 3, 10, 18, and 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Lasko et al (US PGPub No. 2005/0031448) as applied to claims 1, 8, and 15, and in further view of Schleeter (US Patent No. 6,282,746). Regarding claims 3, 10, and 18: Lasko does not teach the air duct having a narrowing taper; Schleeter teaches a blower (100; FIG. 2) including an outlet duct (egress 114 from impeller 104 and housing 116); and wherein the outlet duct tapers to an outlet opening (118; C. 6 Lines 6-15); It would have been obvious to one of ordinary skill in the art of blowers at the time the invention was filed to shape the duct of Lasko in various known manners, such as the tapered duct of Schleeter, in order to control and focus the flow of air from the blower (see C. 1 Lines 22-32 of Schleeter). Regarding claims 19-20: Lasko teaches an oscillation assembly (140) driven via a motor (144) limitations from claim 20, where the second end of the support arm (at the plate portion of 146) is attached to the base (162) and where the base further includes an oscillating mechanism having a second motor (144), a drive gear (150) driven by the second motor, and an oscillation gear (Lasko does not expressly teach a second gear; However, it would have been obvious to one of ordinary skill in the art to provide another geared surface to engage and turn the gear and/or to provide additional gear sets) that engages with the drive gear, where the oscillating mechanism is configured rotate the fan housing in a horizontal plane (C. 5 Lines 17-27); Claim(s) 11-13 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ojeda (US PGPub No. 2014/0328671) as applied to claim 8, and in further view of Bartholmey (US Patent No. 6,282,746). Regarding claim 11: Ojeda does not teach an outlet grill extending along the blower outlet; Bartholmey teaches a blower (20; FIG. 5) in which a grill (82) is located at the outlet of the blower; It would have been obvious to one of ordinary skill in the art of blowers at the time the invention was filed to provide a grill in the outlet opening of the blower of Ojeda, as taught by Bartholemy, in order to protect the user from injuring themselves and to prevent debris from entering the blower. Ojeda further teaches: limitations from claim 12, where an angled interior wall extends upward from the blower outlet toward an upper portion of the main outlet (see annotated FIG. 5 below); PNG media_image1.png 633 476 media_image1.png Greyscale limitations from claim 13, where a first portion of the airflow is expelled in an upward airflow direction from the upper portion of the main outlet and where a second portion of the airflow is expelled in a generally horizontal direction from the lower portion of the main outlet (see arrows in FIG. 6; paragraph 25); Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: US 6760543, 6202322, 4856968, and 10184495 teach blowers and their housings.
