Office Action

§103 §112
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 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. Claims 1-20 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. Claim 1 claims “times of an average moment of inertia of cross sections of the first plate in a first direction fall within a range from 1.14 to 1.18.” However, it is unclear “times” what the average moment of inertia is being compared against. For the purposes of examination, the cited limitation will be interpreted as 1.14 to 1.18 time greater that a plate without embossments. Claims 3, 5, 7, 9, 11, 16, 17, and 19 are rejected for the same reason. Claims 2-6, 8-15 and 17-20 are rejected due to their dependency. 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. Claims 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over Shen (US Publication No. 2020/0187378). Regarding claim 1 (as best understood), Shen discloses a rack assembly (comprised of server chassis 10 and rack 600), comprising: a rack (600); and an electronic device casing (10), mounted in the rack (600) and comprising: a first plate (bottom plate 110), comprising a support portion (upper portion of 110) and at least one embossing structure (pattern 200), wherein the support portion (upper portion of 110) has a support surface (load surface 111), the at least one embossing structure (200) is formed on the support surface (111), sidewalls 120), standing on two opposite sides of the support surface (111) of the support portion (upper portion of 110) of the first plate (110), wherein the first plate (110) and the two second plates (120) together form an accommodation space (accommodation space 122). Regarding the limitation “times of an average moment of inertia of cross sections of the first plate in a first direction fall within a range from 1.14 to 1.18,” because the first plate of the claimed invention has identical structure and proportion to the first plate of Shen, and because the average moment of inertia calculation is simply based on variable distance and cross-section area measurements, the stated limitation is held to be merely a selection of optimal working parameters established through routine experimentation, and thus obvious to a person of ordinary skill in the art. MPEP § 2144.05(II)(A); In re Williams, 36 F.2d 436, 438 (CCPA 1929) ("It is a settled principle of law that a mere carrying forward of an original patented conception involving only change of form, proportions, or degree, or the substitution of equivalents doing the same thing as the original invention, by substantially the same means, is not such an invention as will sustain a patent, even though the changes of the kind may produce better results than prior inventions."). A person of ordinary skill in the art would have had a reasonable expectation of success to formulate the claimed range because doing so would have increased the load bearing capacity of the first plate (see Paragraphs [0028], [0044], and [0049] in Shen). Regarding claim 2, Shen teaches the rack assembly according to claim 1, and further teaches wherein the at least one embossing structure (200) comprises a plurality of embossing structures (see Figures 1-3), and the plurality of embossing structures (200) are arranged in an array (see Figures 2-8). Regarding claim 3 (as best understood), Shen teaches the rack assembly according to claim 1, and further teaches wherein times of an average moment of inertia of cross sections of the first plate in a second direction (between x-direction and y-direction) fall within a range from 1.14 to 1.18, and the second direction (between x-direction and y-direction) intersects the first direction (y-direction). Regarding the limitation “wherein times of an average moment of inertia of cross sections of the first plate in a second direction fall within a range from 1.14 to 1.18,” because the first plate of the claimed invention has identical structure and proportion to the first plate of Shen, and because the average moment of inertia calculation is simply based on variable distant and cross-section area measurements, the stated limitation is held to be merely a selection of optimal working parameters established through routine experimentation, and thus obvious to a person of ordinary skill in the art. MPEP § 2144.05(II)(A); In re Williams, 36 F.2d 436, 438 (CCPA 1929) ("It is a settled principle of law that a mere carrying forward of an original patented conception involving only change of form, proportions, or degree, or the substitution of equivalents doing the same thing as the original invention, by substantially the same means, is not such an invention as will sustain a patent, even though the changes of the kind may produce better results than prior inventions."). A person of ordinary skill in the art would have had a reasonable expectation of success to formulate the claimed range because doing so would have increased the load bearing capacity of the first plate (see Paragraphs [0028], [0044], and [0049] in Shen). Regarding claim 4, Shen teaches the rack assembly according to claim 3, and further teaches wherein the second direction (between x-direction and y-direction) is non-perpendicular to the first direction (y-direction). Regarding claim 5 (as best understood), Shen teaches the rack assembly according to claim 1, and further teaches wherein the times of the average moment of inertia of the sections of the first plate (110) in the first direction (y-direction) fall within a range from 1.15 to 1.17. Regarding the limitation “wherein the times of the average moment of inertia of the sections of the first plate in the first direction fall within a range from 1.15 to 1.17,” because the first plate of the claimed invention has identical structure and proportion to the first plate of Shen, and because the average moment of inertia calculation is simply based on variable distance and cross-section area measurements, the stated limitation is held to be merely a selection of optimal working parameters established through routine experimentation, and thus obvious to a person of ordinary skill in the art. MPEP § 2144.05(II)(A); In re Williams, 36 F.2d 436, 438 (CCPA 1929) ("It is a settled principle of law that a mere carrying forward of an original patented conception involving only change of form, proportions, or degree, or the substitution of equivalents doing the same thing as the original invention, by substantially the same means, is not such an invention as will sustain a patent, even though the changes of the kind may produce better results than prior inventions."). A person of ordinary skill in the art would have had a reasonable expectation of success to formulate the claimed range because doing so would have increased the load bearing capacity of the first plate (see Paragraphs [0028], [0044], and [0049] in Shen). Regarding claim 6, Shen teaches the rack assembly according to claim 1, and further teaches wherein the two second plates (120) are respectively mounted on two opposite sides of the rack (600), and the first direction (y-direction) is parallel to the two second plates (120). Regarding claim 7 (as best understood), Shen discloses an electronic device casing, comprising: a first plate (110), comprising: a support portion (upper portion of 110), having a support surface (loading surface 111); and at least one embossing structure (pattern 200), formed on the support surface (111), 120), standing on two opposite sides of the support surface (opposite sides of 111) of the support portion (upper portion of 110) of the first plate (110), wherein the first plate (110) and the two second plates (120) together form an accommodation space (accommodation space 122). Regarding the limitation “wherein times of an average moment of inertia of cross sections of the first plate in a first direction fall within a range from 1.14 to 1.18,” because the first plate of the claimed invention has identical structure and proportion to the first plate of Shen, and because the average moment of inertia calculation is simply based on variable distant and cross-section area measurements, the stated limitation is held to be merely a selection of optimal working parameters established through routine experimentation, and thus obvious to a person of ordinary skill in the art.

A person of ordinary skill in the art would have had a reasonable expectation of success to formulate the claimed range because doing so would have increased the load bearing capacity of the first plate (see Paragraphs [0028], [0044], and [0049] in Shen).
