Office Action

§103 §112
DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Status of Claims Claims 1-20 are pending. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claim(s) 6 is/are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Re claim 6, claim 6 recites, “the support” in line 2. There is insufficient antecedent basis for this limitation in the claim. It appears this language is intended to recite, “the at leads one support” and will be interpreted as such. 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, 7-9, 14-17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Barnes et al (“Barnes”) (US 11,680,420) in view of Thomson (US 3,720,964). Re claim 1, Barnes discloses a sun shelf (Fig. 1A) comprising: a main body (100) having a first wall (110), a second wall (120), a third wall (115), a fourth wall (see examiner comments), a base (125), the first wall (110) having a first height (height of 110 from 125) from the base (125), the second wall (120) having a second height (height of 120 from 125) from the base (125), the third wall (115) having a third height (height of 115 from 125) from the base (125), and the fourth wall (see examiner comments) having a fourth height (height of that shown in the examiner comments from the front vertical wall of base 125) from the base (125), the fourth height (height of that shown in the examiner comments) being less than (Fig. 1A) the first height (height of 110 from 125), the second height (height of 120 from 125), and the third height (height of 115 from 125), but fails to disclose a first intake, an outlet, and a recess, and a tubular member attached to the main body and extending from the first intake to the outlet. However, Thomson discloses a first intake (Fig. 6-7; 56), an outlet (58), and a recess (Fig. 7, the space which receives 60 and 62 within 64), and a tubular member (62, 64) attached to the main body (52) and extending from (Col 5 line 67-Col 6 line 3) the first intake (56) to the outlet (58). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the sun shelf of Barnes with a first intake, an outlet, and a recess, and a tubular member attached to the main body and extending from the first intake to the outlet as disclosed by Thomson in order to circulate filtering water to maintain cleanliness and safety, as is the normal and logical manner of use of intakes, outlets, and tubular members, and as is well-known and common in the art. Re claim 7, Barnes as modified discloses the sun shelf of claim 1, wherein the first intake is disposed through the fourth wall. However, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the sun shelf of Barnes wherein the first intake is disposed through the fourth wall in order to provide water circulation at the fourth wall, at the front of the sun shelf. It has been held that rearrangement of parts is considered within the level of ordinary skill in the art. In re Japikse, 181 F.2d 1019. Re claim 8, Barnes as modified discloses the sun shelf of claim 1 but fails to disclose wherein the first intake is disposed through the base. However, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the sun shelf of Barnes wherein the first intake is disposed through the base in order to provide water circulation at the base, at the bottom of the sun shelf. It has been held that rearrangement of parts is considered within the level of ordinary skill in the art. In re Japikse, 181 F.2d 1019. Re claim 9, Barnes as modified discloses the sun shelf of claim 1 but fails to disclose wherein the main body defines a second intake; and wherein the tubular member extends from the second intake to the outlet. However, Thomson discloses wherein the main body (Fig. 6-7) defines a second intake (Fig. 6-7; showing two elements 56), wherein the tubular member (62, 64) extends from (Col 5 line 67-Col 6 line 3) the second intake (Fig. 6-7 showing two elements 56) to the outlet (58). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the sun shelf of Barnes wherein the main body defines a second intake; and wherein the tubular member extends from the second intake to the outlet as disclosed by Thomson in order to circulate filtering water to maintain cleanliness and safety, as is the normal and logical manner of use of intakes, outlets, and tubular members, and as is well-known and common in the art. Re claim 14, Barnes as modified discloses the sun shelf of claim 1, wherein the first wall (110), the second wall (120), the third wall (115), and the fourth wall (see examiner comments) are substantially perpendicular to (Fig. 1A) the base (125). Re claim 15, Barnes as modified discloses the sun shelf of claim 1, but fails to disclose wherein the outlet is disposed through the third wall. However, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the sun shelf of Barnes wherein the outlet is disposed through the third wall in order to provide water circulation and/or drainage at the third wall, at the front of the sun shelf. It has been held that rearrangement of parts is considered within the level of ordinary skill in the art. In re Japikse, 181 F.2d 1019. Re claim 16, Barnes as modified discloses the sun shelf of claim 1, Bergstrom discloses wherein the outlet (58) is disposed through the base (bottom surface of 52). Re claim 17, Barnes as modified discloses the sun shelf of claim 1, wherein the first wall (110) has a first sidewall (sidewall of 110), the second wall (120) has a second sidewall (sidewall of 120), the third wall (115) has a third sidewall (sidewall of 115), and the fourth wall (see examiner comments) has a fourth sidewall (sidewall of that shown in the examiner comments); and wherein the recess (Bergstrom: the space into which 60 and 62 are inserted) has a length (which would be along the length of Fig. 1A of Barnes) and a width (which would be along the width of Fig. 1A of Barnes), but fails to disclose the length being equal to about 78 inches measured from the first sidewall to the second sidewall, the width being equal to about 67 ½ inches measured from the fourth sidewall to the third sidewall. However, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the sun shelf of Barnes with the length being equal to about 78 inches measured from the first sidewall to the second sidewall, the width being equal to about 67 ½ inches measured from the fourth sidewall to the third sidewall in order to provide sufficient space on the base for persons utilizing the sun shelf to sit, lounge, or setup chairs. In addition, a change in size is generally recognized as being within the level of ordinary skill in the art. In re Rose, 105 USPQ 237 (CCPA 1955). Claim(s) 2-6, 10-13, 18-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Barnes et al (“Barnes”) (US 11,680,420) in view of Thomson (US 3,720,964) and Bergstrom (US 6,349,427). Re claim 2, Barnes as modified discloses the sun shelf of claim 1, but fails to disclose wherein the main body defines a cavity; and wherein the tubular member is disposed within the cavity. However, Bergstrom discloses wherein the main body (Fig. 1) defines a cavity (Fig. 5, between 37 and 101); and wherein the tubular member (Fig. 1, unlabeled tubing) is disposed within (Fig. 1) the cavity (between 37 and 101). It would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the sun shelf of Barnes wherein the main body defines a cavity; and wherein the tubular member is disposed within the cavity as disclosed by Bergstrom in order to circulate filtering water to maintain cleanliness and safety in an open space to reduce weight. Re claim 3, Barnes as modified discloses the sun shelf of claim 2, Bergstrom discloses wherein the main body (Fig. 5) has a first exterior surface (101); and wherein the cavity (between 101 and 37) extends from the first wall (37) to the first exterior surface (101).
