Claim Rejections - 35 USC § 103 07-20-aia AIA 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 of this title, 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. 07-21-aia AIA 7. Claim (s) 4-5 are/is rejected under 35 U.S.C. 103 as being unpatentable over Fukui in view of Boemmel et al. (Pub. No.: US 2003/0222650 hereinafter mentioned as “Boemmel”) . As per claim 4, Fukui discloses the set of shim elements according to claim 3 as described above but does not explicitly disclose: wherein the outer shape is such that two respective shim elements may be connected to each other by form fit. However, Boemmel further discloses: wherein the outer shape is such that two respective shim elements may be connected to each other by form fit ( Fig. 8, see the sub-boxes/shim-elements 77, 78 and 79 can be assembled inter-engaging with one another by form fit. Also see [0037] ) . It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to implement the feature relative to the “ wherein the outer shape is such that two respective shim elements may be connected to each other by form fit ” disclosed by Boemmel into Fukui, with the motivation and expected benefit related to improving the system and measurements by enabling the shim-elements to be pulled along toward the left in longitudinal direction out of the shim tray receptacle together (Boemmel, Paragraph [0037]), thus, also achieving a simple manipulation of the shim tray (Boemmel, Paragraph [0009]). Furthermore, Fukui states that “ features described in the embodiments above illustrate an example of the contents of the present invention, and can be combined with other known techniques, or can be partially omitted or changed within the scope not departing from the gist of the present invention ” (Fukui, Paragraph [0051]). Furthermore, Boemmel states that “ Although modifications and changes may be suggested by those skilled in the art, it is the intention of the inventors to embody within the patent warranted hereon all changes and modifications as reasonably and properly come within the scope of their contribution to the art ” (Abrahamson, Paragraph [0038]). As per claim 5, Fukui discloses the set of shim elements according to claim 1 as described above but does not explicitly disclose: wherein the shim elements are each provided with interlockings such that respective two shim elements may be interlocked to each other via these interlockings. However, Boemmel further discloses: wherein the shim elements are each provided with interlockings such that respective two shim elements may be interlocked to each other via these interlockings ( Fig. 8, see the sub-boxes/shim-elements 77, 78 and 79 can be assembled inter-engaging with one another by form fit. Also see [0037] ) . It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to implement the feature relative to the “ wherein the shim elements are each provided with interlockings such that respective two shim elements may be interlocked to each other via these interlockings ” disclosed by Boemmel into Fukui, with the motivation and expected benefit related to improving the system and measurements by enabling the shim-elements to be pulled along toward the left in longitudinal direction out of the shim tray receptacle together (Boemmel, Paragraph [0037]), thus, also achieving a simple manipulation of the shim tray (Boemmel, Paragraph [0009]) . 07-21-aia AIA 8. Claim (s) 8 and 10 are/is rejected under 35 U.S.C. 103 as being unpatentable over Fukui . As per claim 8, Fukui discloses the set of shim elements according to claim 1 as described above but does not explicitly disclose an indication on its outside which indicates the relative amount of shim iron comprised by the respective shim element . However, one of ordinary skill in the art would find an obvious choice to try implementing the feature relative to the “ indication on its outside which indicates the relative amount of shim iron comprised by the respective shim element ” with the motivation and expected benefit related to using the proper amount of shim iron permitted to be disposed in each depression/shim-pocket to maintain the necessary magnetic field homogeneity ( see SAKAKIBARA Pub. No.: US 2018/0284205, [0053]-[0055] ) . As per claim 10, Fukui discloses the set of shim elements and MR apparatus according to claim 9 according to claim 8 as described above. Fukui further discloses: wherein all shim openings are completely filled with a respective set of shim elements ( Figs. 1-4, see the superconducting-magnet 100 with a plurality of openings along the its longitudinal-axis, each opening receives one magnetic-field-adjusting-device 150 with its shim-trays 152 that has a plurality of openings/shim-pockets 153, respectively, so each of the is individually shim-blocks 154 with its respective spacers 156 are individually inserted into their respective openings of the superconducting-magnet 100. Also see [0026]-[0027] ) . Allowable Subject Matter 12-151-08 AIA 07-43 12-51-08 9. Claim (s) 7 and 14 are/is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. 10. The following is an examiner's statement of reasons for the objection: 11. Regarding claim 7, the prior art of record, alone or in combination, does not disclose or suggest the below underlined limitations incorporated together with the other claimed limitations not mentioned herein: wherein the shim elements is arranged comprise at least one dummy block which is separate from all shim blocks of the set such that also the dummy block may be individually inserted into a shim opening of a magnetic field generating unit of the magnetic resonance apparatus, wherein the dummy block is free of any shim iron. 12. Regarding claim 14, the prior art of record, alone or in combination, does not disclose or suggest the below underlined limitations incorporated together with the other claimed limitations not mentioned herein: wherein the shim elements are connected to each other by a string before insertion into the shim opening. 13. The prior art of record does not anticipate the limitations of the independent claims. Furthermore, there is not any obvious motivation for an ordinary skilled in the art to combine some and/or all of the features of the prior art of record to achieve the features of the allowable subject matter. In addition, it will further require substantial structural modification of the components that will also require substantial modification of the measurements, and configurations to achieve the features of the allowable subject matter. 07-96 AIA 14. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. a) PAN (Pub. No.: US 2020/0072924) teaches that “ The passive shim bar tool is a space holder respectively dummy of a passive shim bar . The annulus between the inner casing and the outer casing is casted, preferably with resin. Since the dummy is inserted in the first recess, entering of casting material to the first recess can be avoided ” (Paragraph [0045]) .
