Patentability shall not be negated by the manner in which the invention was made. The factual inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. If this application names joint inventors, Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 12-18 are rejected under 35 U.S.C. 103 as being unpatentable over TBK in view of Humphrey et al (US 2015/0287276 A1). Regarding claim 12, TBK discloses a gaming system comprising a first electronic gaming machine displaying a keno card comprising a first quantity of spots, wherein the keno card is part of a play of a keno game displayed by a display device of the first electronic gaming machine (p. 2), cause a display of indications of a plurality of spot sub-groups, wherein each of spot sub-groups comprises a plurality of the first quantity of spots of the keno card (p. 2: top and bottom groups), displaying one of the plurality of spot sub-groups associated with the first electronic gaming machine (p. 2), cause a display, by the display device of the second electronic gaming machine, of indications of each of a second quantity of drawn spots selected from the first quantity of spots of the keno card by the first electronic gaming machine (p. 3), and cause a display of an indication of a determination that one of the spot sub-groups is a winning spot sub-group (p. 4), wherein the determination is based on respective quantities of the drawn spots in each of the spot sub-groups (p. 3: Hit 12), and regardless of player spots for the play of the keno game displayed by the first electronic gaming machine and regardless of a quantity of matches between the player spots and the drawn spots for the play of the keno game displayed by the first electronic gaming machine (p. 4: player wins $5 (1 credit) for top matching 12 numbered balls while bottom only matched 8). Humphrey suggests—where TBK does not disclose—a second electronic gaming machine (Fig. 3A) and a keno side game server comprising a processor, and a memory device storing a plurality of instructions (Fig. 3A), causing a display, by a display device of the second electronic gaming machine of a keno card comprising a first quantity of spots (Fig. 2L), wherein the keno card is part of a play of a keno game displayed by a display device of the first electronic gaming machine (Fig. 2M) and displaying by the display device of the electronic gaming machine, of an indication of one of the plurality of spot sub-groups being associated the second electronic gaming machine (Fig. 2M). It would have been obvious to a person of ordinary skill in the art prior to the effective filing date of the invention to combine the disclosures of TBK and Humphrey in order to make the game more interesting and competitive. Regarding claim 13, Humphrey suggests—where TBK does not disclose—wherein the display, by the display device of the second electronic gaming machine, of the keno card is in a service window (Fig. 2P). It would have been obvious to a person of ordinary skill in the art prior to the effective filing date of the invention to combine the disclosures of TBK and Humphrey in order to make the game more interesting and competitive. Regarding claim 14, TBK discloses wherein the quantity of the spot sub-groups is two (p. 2: top and bottom groups). Regarding claim 15, TBK discloses selecting, for the first electronic gaming machine, the spot sub-group associated with that electronic gaming machine (p. 5: game machine defaults to top group for the house). Humphrey suggests—where TBK does not disclose—a second electronic gaming machine (Fig. 3A). It would have been obvious to a person of ordinary skill in the art prior to the effective filing date of the invention to combine the disclosures of TBK and Humphrey in order to make the game more interesting and competitive. Regarding claim 16, TBK discloses selecting select, for the first electronic gaming machine, the spot sub-group associated with that electronic gaming machine based on a player input at one of the first electronic gaming machine and the second electronic gaming machine pp. 6-7: player can choose to play top or bottom). Humphrey suggests—where TBK does not disclose—a second electronic gaming machine (Fig. 3A). It would have been obvious to a person of ordinary skill in the art prior to the effective filing date of the invention to combine the disclosures of TBK and Humphrey in order to make the game more interesting and competitive Regarding claim 17, TBK discloses displaying, by the display device of the electronic gaming machine associated with the winning spot sub-group, of an award amount associated with that spot sub-group (p. 4: player wins $5 (1 credit) for top matching 12 numbered balls while bottom only matched 8). Regarding claim 18, TBK discloses displaying, by the display device of the electronic gaming machine associated with the winning spot sub-group, of a point amount associated with that spot sub-group, wherein the point amount is based on the quantity of drawn spots in the winning spot sub-group (p. 3: Hit 12). Claims 19 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over TBK in view of Arezina et al (US 2009/0117989 A1). Claim 19 subsumes the limitations of claim 1 above and is accordingly rejected for the same reasons given supra. Further regarding claim 19, Arezina suggests—where TBK does not disclose—a keno side game server (¶ [0054]) operable to communicate with a first quantity of electronic gaming machines (¶ [0066]), the keno side game server comprising a processor, and a memory device storing a plurality of instructions (¶ [0066]), selecting a second quantity of electronic gaming machines, the second quantity being less than the first quantity (¶ [0080]: bonus-game options available only to club members), wherein the keno card is part of a play of a keno game displayed by a display device of one of the first quantity of electronic gaming machines (Fig. 11). It would have been obvious to a person of ordinary skill in the art prior to the effective filing date of the invention to combine the disclosures of TBK and Arezina in order to make the secondary game exclusive to certain valuable patrons, thus creating a retention incentive. Regarding claim 20, Arezina suggests—where TBK does not disclose—wherein one of the second quantity of electronic gaming machines is the electronic gaming machine that displays the play of the keno game (¶ [0080]: bonus-game options available only to club members). It would have been obvious to a person of ordinary skill in the art prior to the effective filing date of the invention to combine the disclosures of TBK and Arezina in order to make the secondary game exclusive to certain valuable patrons, thus creating a retention incentive.
