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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on June 18, 2026 has been entered. Response to Amendment The amendment filed June 18, 2024 is objected to under 35 U.S.C. 132(a) because it introduces new matter into the disclosure. 35 U.S.C. 132(a) states that no amendment shall introduce new matter into the disclosure of the invention. The added material which is not supported by the original disclosure is as follows: “wherein the CAMM carrier includes a bottom hook to secure the bottom CAMM” in claims 1, 11, and 20. Applicant is required to cancel the new matter in the reply to this Office Action. Response to Arguments Applicant's arguments filed June 18, 2026 have been fully considered but they are not persuasive. Applicant argues none of the cited prior art teaches “wherein the CAMM carrier includes a bottom hook to secure the bottom CAMM and a top hook to secure the top CAMM” (Arguments, page 5). However, after further search and consideration, Examiner submits the primary reference, Tondreault (US Patent No. 5769668), teaches wherein the CAMM carrier (10) includes a hook (Figures 1-2, alignment apparatus 51, including key 52 and alignment clip PNG media_image1.png 455 664 media_image1.png Greyscale PNG media_image2.png 458 580 media_image2.png Greyscale 62, where 62 includes hooks 74, 76) to secure a CAMM (12; see Figure 1 and 6 below). PNG media_image3.png 382 522 media_image3.png Greyscale Because Wang discloses a top and bottom CAMM and suggests a similar alignment feature (see annotated Figure 3 below), Examiner submits it would have been prima facie obvious to one of ordinary skill in the art before the effective file date of the claimed invention to have combined the retention hooks of Tondreault to a top and bottom portion of the CAMM carrier of Wang as modified by Schnell, Chang, and Wang ‘877, to secure the top and bottom CAMMs. Doing so would have ensured proper alignment between the memory modules and the CAMM carrier (see col. 5, ln. 13-50 in Tondreault). For these reasons, and the reasons detailed below, claims 1-20 stand rejected. Drawings The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, “a bottom hook to secure the bottom CAMM” must be shown or the feature(s) canceled from the claim(s). No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1-20 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Claims 1, 11, and 20 claim “wherein the CAMM carrier includes a bottom hook to secure the bottom CAMM and a top hook to secure the top CAMM”. However, Paragraphs [0021] and [0027] of the Specification only disclose “CAMM carrier 210 includes top CAMM retention hooks 212” and “It will be further understood that top CAMM 332 is secured within the recess in CAMM holder 200 by one or more retention hooks 212, as illustrated in FIG. 2D.” The Specification does not provide for “a bottom hook to secure the bottom CAMM” in such a way as to reasonably convey to one skilled in the relevant art that the inventor at the time the application was filed, had possession of the claimed invention. Claims 2-10 and 12-19 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, 5-11, and 15-20 are rejected under 35 U.S.C. 103 as being unpatentable over Wang (US Patent No. 8357003) in view of Schnell (US Publication No. 2022/0335981), Chang (US Publication No. 2018/0310441), Wang ‘877 (US Publication No. 2008/0038877), and Tondreault (US Patent No. 5769668). Regarding claim 1, Wang discloses a holder (Figure 2, comprised of connecting base 10 and metal latch members 3) for stacked compression attached first and second electronic cards 4, 5), the holder (see Figure 2) comprising: a CAMM carrier (connection base 10) having a first recessed area (slot 12) for receiving a bottom one of the CAMMs (5), and a second recessed area (slot 11) for receiving a top one of the CAMMs (4); and a retention plate (latch member 3) affixed to the CAMM carrier (10), the retention plate (3) configured to support a cantilevered portion of the top CAMM (end of 4). Wang does not explicitly teach wherein the compression attached modules are compression attached memory modules. However, Schnell teaches a holder (Figure 11, comprised of structure for compression connectors 750, 754; see also Figure 10) for stacked compression attached memory modules (CAMMs) (cDIMMs 752, 756; see Paragraph [0024]). It would have been prima facie obvious to one of ordinary skill in the art before the effective file date of the claimed invention to have substituted the circuit cards of Wang for the CAMM circuit cards of Schnell, according to known methods to yield the predictable results of installing circuit cards onto a printed circuit board. Doing so would have also provided a compact carrier structure capable of accommodating circuit cards with increased high speed signal frequency (see Paragraphs [0059]-[0061] in Schnell). Wang in view of Schnell does not teach wherein the CAMM carrier is configured to surround four peripheral edges of the bottom CAMM and the top CAMM. However, Chang teaches a CAMM carrier (cover 140), wherein the CAMM carrier (140) is configured to surround four peripheral edges of a CAMM (electromagnetic radiation device 130). Wang ‘877 also teaches a CAMM carrier (housing 310) sized to surround four peripheral edges of a bottom CAMM (PCBA 50-2) and a top CAMM (PCBA 50-1). Because Chang teaches a CAMM connector similar to Wang, it would have been prima facie obvious to one of ordinary skill in the art before the effective file date of the claimed invention to have combined the CAMM carrier of Chang to the CAMM carrier of Wang as modified by Schnell, such that the CAMM carrier was sized to cover the top and bottom CAMMs, as taught in Wang ‘877. Doing so would have provided electromagnetic radiation shielding for a high frequency electromagnetic radiation device (see Paragraphs [0008]-[0017] in Chang; see Paragraph [0062] in Wang ‘877). Modifying the CAMM carrier to cover both top and bottom CAMMs as taught in Wang ‘877 would have been obvious considering 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 size to cover the top and bottom CAMMs because doing so would have allowed the single cover to protect both of the CAMMs in Wang from EMI, as taught in both Chang and Wang ‘877 (see Paragraphs [0008]-[0017] in Chang; see Paragraph [0062] in Wang ‘877). Wang in view of Schnell, Chang, and Wang ‘877 does not explicitly teach wherein the CAMM carrier includes a bottom hook to secure the bottom CAMM and a top hook to secure the top CAMM. However, Tondreault teaches a holder (Figure 1, comprised of connector 10 and clips 46) for a compression attached memory module (CAMM) (module 12), the holder comprised of a CAMM carrier (10) and a retention plate (46), wherein the CAMM carrier (10) includes a hook (Figures 1-2, alignment apparatus 51, including key 52 and alignment clip 62, where 62 including hooking portions 74, 76) to secure a CAMM (12). Because Wang suggests a similar alignment/securing feature (see annotated Figure 3 above), it would have been prima facie obvious to one of ordinary skill in the art before the effective file date of the claimed invention to have combined the retention hooks of Tondreault to a top and bottom portion of the CAMM carrier of Wang as modified by Schnell, Chang, and Wang ‘877, to secure the top and bottom CAMMs. Doing so would have ensured proper alignment between the memory modules and the CAMM carrier (see col. 5, ln. 13-50 in Tondreault), and considering it is well established that a mere duplication of parts has no patentable significance unless a new and unexpected result is produced. See MPEP § 2144.04 and In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1960). Regarding claim 5, Wang in view of Schnell, Chang, Wang ‘877, and Tondreault teaches the holder of claim 1, and further teaches (in Wang) wherein the retention plate (3) includes a bottom CAMM contact spring (first main arm 32). Regarding claim 6, Wang in view of Schnell, Chang, Wang ‘877, and Tondreault teaches the holder of claim 5, and further teaches (in Wang) wherein the bottom CAMM contact spring (32) is configured to mount the CAMM carrier (10) to the bottom CAMM (5, as modified by Schnell). Regarding claim 7, Wang in view of Schnell, Chang, Wang ‘877, and Tondreault teaches the holder of claim 6, and further teaches (in Wang) wherein the retention plate (3) further includes a top CAMM contact spring (second main arm 33). Regarding claim 8, Wang in view of Schnell, Chang, Wang ‘877, and Tondreault teaches the holder of claim 7, and further teaches (in Wang) wherein the top CAMM contact spring (33) is configured to support the cantilevered portion of the top CAMM (end of 4, as modified by Schnell). Regarding claim 9, Wang in view of Schnell, Chang, Wang ‘877, and Tondreault teaches the holder of claim 1, and further teaches wherein the CAMM carrier (10 in Wang, as modified by Tondreault) includes a retention hook (head 76 of alignment clip 62 in Tondreault) configure to secure the top CAMM (4 in Wang) to the CAMM carrier (10 in Wang, as modified by Tondreault). Regarding claim 10, Wang in view of Schnell, Chang, Wang ‘877, and Tondreault teaches the holder of claim 1, and further teaches (in Wang) wherein the retention plate (3) is fabricated of a metal material (col. 5, ln. 5-7, “the latch member 3 is a one-piece metal member structure integrally formed by stamping and forming a metal plate”). Regarding claim 11, Wang discloses a method for retaining compression attached first and second electronic cards 4, 5), the method comprising: installing a bottom one of the CAMMs (second card 5) to a motherboard (circuit board 6, via connection with latch members 3 and connection base 10); placing a CAMM carrier (connection base 10) atop the bottom CAMM (5), the bottom CAMM (5) fitting into a first recessed area (second slot 12) for receiving the bottom CAMM (5); affixing a retention plate (latch member 3) to the CAMM carrier (10); securing a top one of the CAMMS (first card 4) to the CAMM carrier (10), the top CAMM (5) fitting into a second recessed area (first slot 11) for receiving the top CAMM (4); and supporting, by the retention plate (3), a cantilevered portion of the top CAMM (end of 5). Wang does not explicitly teach wherein the compression attached modules are compression attached memory modules. However, Schnell teaches a method for retaining compression attached memory modules (CAMMs) (cDIMMs 752, 756; see Paragraph [0024] and Figures 10-11). It would have been prima facie obvious to one of ordinary skill in the art before the effective file date of the claimed invention to have substituted the circuit cards of Wang for the CAMM circuit cards of Schnell, according to known methods to yield the predictable results of installing circuit cards onto a printed circuit board. Doing so would have also provided a compact carrier structure capable of accommodating circuit cards with increased high speed signal frequency (see Paragraphs [0059]-[0061] in Schnell). Wang in view of Schnell does not teach wherein the CAMM carrier is configured to surround four peripheral edges of the bottom CAMM and the top CAMM. However, Chang teaches placing a CAMM carrier (cover 140) atop a CAMM (electromagnetic radiation device 130), wherein the CAMM carrier (140) is configured to surround four peripheral edges of the CAMM (130). Wang ‘877 also teaches a CAMM carrier (housing 310) sized to surround four peripheral edges of a bottom CAMM (PCBA 50-2) and a top CAMM (PCBA 50-1). Because Chang teaches a CAMM connector similar to Wang, it would have been prima facie obvious to one of ordinary skill in the art before the effective file date of the claimed invention to have combined the methods of attaching the CAMM carrier of Chang to the CAMM carrier of Wang, such that the CAMM carrier was sized to cover the top and bottom CAMMs, as taught in Wang ‘877. Doing so would have provided electromagnetic radiation shielding for a high frequency electromagnetic radiation device (see Paragraphs [0008]-[0017] in Chang; see Paragraph [0062] in Wang ‘877). Modifying the CAMM carrier to cover both top and bottom CAMMs as taught in Wang ‘877 would have been obvious considering 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 size to cover the top and bottom CAMMs because doing so would have allowed the single cover to protect both of the CAMMs in Wang from EMI, as taught in both Chang and Wang ‘877 (see Paragraphs [0008]-[0017] in Chang; see Paragraph [0062] in Wang ‘877). Wang in view of Schnell, Chang, and Wang ‘877 does not explicitly teach wherein the CAMM carrier includes a bottom hook to secure the bottom CAMM and a top hook to secure the top CAMM. However, Tondreault teaches a holder (Figure 1, comprised of connector 10 and clips 46) for a compression attached memory module (CAMM) (module 12), the holder comprised of a CAMM carrier (10) and a retention plate (46), wherein the CAMM carrier (10) includes a hook (Figures 1-2, alignment apparatus 51, including key 52 and alignment clip 62, where 62 including hooking portions 74, 76) to secure a CAMM (12). Because Wang suggests a similar alignment/securing feature (see annotated Figure 3 above), it would have been prima facie obvious to one of ordinary skill in the art before the effective file date of the claimed invention to have combined the retention hooks of Tondreault to a top and bottom portion of the CAMM carrier of Wang as modified by Schnell, Chang, and Wang ‘877, to secure the top and bottom CAMMs. Doing so would have ensured proper alignment between the memory modules and the CAMM carrier (see col. 5, ln. 13-50 in Tondreault), and considering it is well established that a mere duplication of parts has no patentable significance unless a new and unexpected result is produced. See MPEP § 2144.04 and In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1960). Regarding claim 15, Wang in view of Schnell, Chang, Wang ‘877, and Tondreault teaches the method of claim 11, and further teaches (in Wang) wherein the retention plate (3) includes a bottom CAMM contact spring (first main arm 32). Regarding claim 16, Wang in view of Schnell, Chang, Wang ‘877, and Tondreault teaches the method of claim 15, and further teaches (in Wang) wherein the bottom CAMM contact spring (32) is configured to mount the CAMM carrier (10) to the bottom CAMM (5, as modified by Schnell). Regarding claim 17, Wang in view of Schnell, Chang, Wang ‘877, and Tondreault teaches the method of claim 16, and further teaches (in Wang) wherein the retention plate (3) further includes a top CAMM contact spring (second main arm 33). Regarding claim 18, Wang in view of Schnell, Chang, Wang ‘877, and Tondreault teaches the method of claim 17, and further teaches (in Wang) wherein the top CAMM contact spring (33) is configured to support the cantilevered portion of the top CAMM (end of 4, as modified by Schnell). Regarding claim 19, Wang in view of Schnell, Chang, Wang ‘877, and Tondreault teaches the method of claim 11, and further teaches wherein the CAMM carrier (10 in Wang, as modified by Tondreault) includes a retention hook (head 76 of alignment clip 62 in Tondreault) configure to secure the top CAMM (4 in Wang) to the CAMM carrier (10 in Wang, as modified by Tondreault). Regarding claim 20, Wang discloses an information handling system, comprising: a motherboard (circuit board 6); a bottom compression attached second electronic card 5); a top CAMM (first electronic card 4); and a holder (comprised of electrical connector base 10 and latch member 3) to stack the bottom CAMM (5) and the top CAMM (4), the holder (10, 3) including: a CAMM carrier (electrical connector base 10) having a first recessed area (second slot 12) for receiving the bottom CAMM (5), and a second recessed area (first slot 11) for receiving the top CAMM (4); and a retention plate (3) affixed to the CAMM carrier (10), the retention plate (3) configured to support a cantilevered portion of the top CAMM (end of 4). Wang does not explicitly teach wherein the compression attached modules are compression attached memory modules. However, Schnell teaches a holder (Figure 11, comprised of structure for compression connectors 750, 754; see also Figure 10) for compression attached memory modules (CAMMs) (cDIMMs 752, 756; see Paragraph [0024]). It would have been prima facie obvious to one of ordinary skill in the art before the effective file date of the claimed invention to have substituted the circuit cards of Wang for the CAMM circuit cards of Schnell, according to known methods to yield the predictable results of installing circuit cards onto a printed circuit board. Doing so would have also provided a compact carrier structure capable of accommodating circuit cards with increased high speed signal frequency (see Paragraphs [0059]-[0061] in Schnell). Wang in view of Schnell does not teach wherein the CAMM carrier is configured to surround four peripheral edges of the bottom CAMM and the top CAMM. However, Chang teaches a CAMM carrier (cover 140), wherein the CAMM carrier (140) is configured to surround four peripheral edges of a CAMM (electromagnetic radiation device 130). Wang ‘877 also teaches a CAMM carrier (housing 310) sized to surround four peripheral edges of a bottom CAMM (PCBA 50-2) and a top CAMM (PCBA 50-1). Because Chang teaches a CAMM connector similar to Wang, it would have been prima facie obvious to one of ordinary skill in the art before the effective file date of the claimed invention to have combined the CAMM carrier of Chang to the CAMM carrier of Wang, such that the CAMM carrier was sized to cover the top and bottom CAMMs, as taught in Wang ‘877. Doing so would have provided electromagnetic radiation shielding for a high frequency electromagnetic radiation device (see Paragraphs [0008]-[0017] in Chang; see Paragraph [0062] in Wang ‘877). Modifying the CAMM carrier to cover both top and bottom CAMMs as taught in Wang ‘877 would have been obvious considering 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 size to cover the top and bottom CAMMs because doing so would have allowed the single cover to protect both of the CAMMs in Wang from EMI, as taught in both Chang and Wang ‘877 (see Paragraphs [0008]-[0017] in Chang; see Paragraph [0062] in Wang ‘877). Wang in view of Schnell, Chang, and Wang ‘877 does not explicitly teach wherein the CAMM carrier includes a bottom hook to secure the bottom CAMM and a top hook to secure the top CAMM. However, Tondreault teaches a holder (Figure 1, comprised of connector 10 and clips 46) for a compression attached memory module (CAMM) (module 12), the holder comprised of a CAMM carrier (10) and a retention plate (46), wherein the CAMM carrier (10) includes a hook (Figures 1-2, alignment apparatus 51, including key 52 and alignment clip 62, where 62 including hooking portions 74, 76) to secure a CAMM (12). Because Wang suggests a similar alignment/securing feature (see annotated Figure 3 above), it would have been prima facie obvious to one of ordinary skill in the art before the effective file date of the claimed invention to have combined the retention hooks of Tondreault to a top and bottom portion of the CAMM carrier of Wang as modified by Schnell, Chang, and Wang ‘877, to secure the top and bottom CAMMs. Doing so would have ensured proper alignment between the memory modules and the CAMM carrier (see col. 5, ln. 13-50 in Tondreault), and considering it is well established that a mere duplication of parts has no patentable significance unless a new and unexpected result is produced. See MPEP § 2144.04 and In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1960). Claims 2-4 and 12-14 are rejected under 35 U.S.C. 103 as being unpatentable over Wang (US Patent No. 8357003), Schnell (US Publication No. 2022/0335981), Chang (US Publication No. 2018/0310441), Wang ‘877 (US Publication No. 2008/0038877), Tondreault (US Patent No. 5769668), and in further view of Kato (US Publication No. 2012/0164864). Regarding claim 2, Wang in view of Schnell, Chang, Wang ‘877, and Tondreault teaches the holder of claim 1, but does not teach wherein the retention plate includes a bottom CAMM retention screw hole. However, Kato teaches wherein a retention plate (arm 300, corresponding to 3 in Wang) includes a bottom CAMM retention screw hole (hole 512 in attached portion 510, where 510 in Kato corresponds to soldering portion 36 in Wang; see Paragraphs [0027]-[0028]; NOTE: attached portion 510 in Kato and portion 36 in Wang both being soldered to motherboard). It would have been prima facie obvious to one of ordinary skill in the art before the effective file date of the claimed invention to have combined the screw and screw holes of Kato to the soldering portions of Wang as modified by Schnell, Chang, Wang ‘877, and Tondreault. Doing so would have reinforced the soldered connection between the retention plate and the motherboard (see Paragraphs [0027]-[0028] in Kato). Regarding claim 3, Wang in view of Schnell, Chang, Wang ‘877, Tondreault, and Kato teaches the holder of claim 2, and further teaches wherein the bottom CAMM retention screw hole (512 of Kato formed in 36 of Wang) is configured to secure the bottom CAMM (5 in Wang, as modified by Schnell) to a motherboard (circuit board 6 in Wang; where 5 in Wang, as modified by Schnell, is secured to motherboard 6 by virtue of soldering portion 36 of latch member 3 being soldered and screwed (as modified by Kato) to motherboard 6). Regarding claim 4, Wang in view of Schnell, Chang, Wang ‘877, Tondreault, and Kato teaches the holder of claim 3, and further teaches wherein the bottom CAMM retention screw hole (512 of Kato formed in 36 of Wang) is further configured to secure the CAMM carrier (10 in Wang) to the bottom CAMM (5 in Wang, as modified by Schnell; where screw hole 512 is used to secure latch member 3 in a stable position relative to carrier 10, and where member 3 is used to establish a secure connection between modules 4, 5 (as modified by Schnell) and carrier 10). Regarding claim 12, Wang in view of Schnell, Chang, Wang ‘877, and Tondreault teaches the method of claim 11, but does not teach wherein the retention plate includes a bottom CAMM retention screw hole. However, Kato teaches wherein a retention plate (arm 300, corresponding to 3 in Wang) includes a bottom CAMM retention screw hole (hole 512 in attached portion 510, where 510 in Kato corresponds to soldering portion 36 in Wang; see Paragraphs [0027]-[0028]; NOTE: attached portion 510 in Kato and portion 36 in Wang both being soldered to motherboard). It would have been prima facie obvious to one of ordinary skill in the art before the effective file date of the claimed invention to have combined the screw and screw holes of Kato to the soldering portion of Wang as modified by Schnell, Chang, Wang ‘877, and Tondreault. Doing so would have reinforced the soldered connection between the retention plate and the motherboard (see Paragraphs [0027]-[0028] in Kato). Regarding claim 13, Wang in view of Schnell, Chang, Wang ‘877, Tondreault, and Kato teaches the method of claim 12, and further teaches wherein the bottom CAMM retention screw hole (512 of Kato formed in 36 of Wang) is configured to secure the bottom CAMM (5 in Wang, as modified by Schnell) to the motherboard (circuit board 6 in Wang; where 5 in Wang, as modified by Schnell, is secured to motherboard 6 by virtue of soldering portion 36 of latch member 3 being soldered and screwed (as modified by Kato) to motherboard 6). Regarding claim 14, Wang in view of Schnell, Chang, Wang ‘877, Tondreault, and Kato teaches the method of claim 13, and further teaches wherein the bottom CAMM retention screw hole (512 of Kato formed in 36 of Wang) is further configured to secure the CAMM carrier (10 in Wang) to the bottom CAMM (5 in Wang, as modified by Schnell; where screw hole 512 is used to secure latch member 3 in a stable position relative to carrier 10, and where member 3 is used to establish a secure connection between modules 4, 5 (as modified by Schnell) and carrier 10).
