Office Action

§101 §102
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 . 2. This communication is responsive to Application No. 18/337,604 filed on 06/20/2023. Claims 1-16 are currently pending and have been examined. Information Disclosure Statement IDS filed on 06/20/2023 is considered. The drawings filed on 06/20/2023 are noted. Claim Rejections - 35 USC § 101 6. 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claims 1-16 are rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more. The claims recite the limitations of: “a method for operating a casino gaming system”. The limitation of operating a casino gaming system, as drafted, is a process that, under its broadest reasonable interpretation, covers performance of the limitation in the mind. That is, nothing in the claims preclude the step from practically being performed in the mind. If a claim limitation, under its broadest reasonable interpretation, covers performance of the limitation in the mind, then it falls within the “Mental Processes” grouping of abstract ideas. Accordingly, claims 1-16 recite an abstract idea. This judicial exception is not integrated into a practical application. In particular, the claims only recite one additional element – using a sensor (s) to detect presence of cryptocurrency in the transfer wallet; withdrawing the cryptocurrency from the transfer wallet to perform both detecting and withdrawing steps. The sensor in both steps recite at a high-level of generality (i.e., as a generic computer processing cryptocurrency transaction) such that it amounts no more than mere instructions to apply the exception. Accordingly, this additional element does not integrate the abstract idea into a practical application because it does not impose any meaningful limits on practicing the abstract idea. The claims are directed to an abstract idea. In the instant case, the claims do not include additional elements that are sufficient to amount to significantly more than the judicial exception. As discussed above with respect to integration of the abstract idea into a practical application, the additional element of depositing the cryptocurrency into the casino main wallet; computing a current cash value of the cryptocurrency; and depositing credits equivalent to the current cash value into the player’s unified wallet, and are determined to be well-understood, routine, conventional activity in the field. Thus, the additional element fails to ensure the claims as a whole amount to significantly more than the judicial exception itself. Accordingly, claims 1-16 are ineligible under 35 U.S.C 101. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. 8.
