Office Action

§101 §103 §DOUBLEPATENT
DETAILED ACTION Acknowledgements Claims 1-20 are pending. Claims 1-20 have been examined. 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 . Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP §§ 706.02(l)(1) - 706.02(l)(3) for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/process/file/efs/guidance/eTD-info-I.jsp. Claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of U.S. Patent No. 11,741,442 and 12,493,863. Although the claims at issue are not identical, they are not patentably distinct from each other because all the claims at issue are recited in claims 1-20 of U.S. Patent No. 11,741,442 and 12,493,863.

Claim Rejections - 35 USC §101 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 1-20 are rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more. Analysis In the instant case, claims 1-7 are directed to a method, claims 8-14 are directed to a system and 15-20 are directed to CRM. Therefore, these claims fall within the four statutory categories of invention. The claim(s) recite(s) processing withdrawal transaction request. Specifically, the claims recite “receiving a withdrawal request from a math based currency (MBC) account holder, the withdrawal request comprising a cryptocurrency withdrawal amount; exchanging the cryptocurrency withdrawal amount of a different currency type of the MBC account holder; providing the cryptocurrency withdrawal amount in the different currency type to the MBC account holder; creating a ... associated with an amount of cryptocurrency equivalent to a difference between the cryptocurrency withdrawal amount and a cryptocurrency account amount; and transferring additional cryptocurrency into a ... in response to determining a pooled account database amount is below a threshold cryptocurrency amount.”, which is “commercial or legal interactions” within the “certain methods of organizing human activity” grouping of abstract ideas in prong one of step 2A of the Alice/Mayo test (See MPEP 2106) because the claims involve a series of steps for processing withdrawal transaction request. Accordingly, the claims recite an abstract idea. This judicial exception is not integrated into a practical application because, when analyzed under prong two of step 2A of the Alice/Mayo test (See MPEP 2106), the additional element(s) of the claim(s) such as the use of processor, processing circuit, public and private key pair, pooled account database and processor-readable medium merely use(s) a computer as a tool to perform an abstract idea. The processors and memories are recited at a high-level of generality (i.e., as a generic processor performing a generic computer function of processing withdrawal transaction request) such that it amounts no more than mere instructions to apply the exception using a generic computer components. Accordingly, the additional elements do not impose any meaningful limits on practicing the abstract idea, and the claims are directed to an abstract idea. 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 using processor, processing circuit, public and private key pair, pooled account database and processor-readable medium to perform withdrawal transaction steps amounts to no more than mere instructions to apply the exception using a generic computer components. Mere instructions to apply an exception using a generic computer components cannot provide an inventive concept. The claim is not patent eligible. Dependent claims 2, 9 and 16 describe exchange. Dependent claims 3, 10 and 17 describe broadcasting transaction. Dependent claims 4, 11 and 18 describe pooled account database. Dependent claims 5, 12 and 19 describe overlay ledger. Dependent claims 6 and 13 describe currency type. Dependent claims 7, 14 and 20 describe transaction device. These claims further recite the abstract idea of certain methods of organizing human activity. This judicial exception is not integrated into a practical application because the additional element(s) of the claim(s) such as the use of processor, processing circuit, public and private key pair, pooled account database and processor-readable medium merely use(s) a computer as a tool to perform an abstract idea. The claims do not include additional elements that are sufficient to amount to significantly more than the judicial exception. The claims are not patent eligible. Viewed as a whole, the combination of elements recited in the claims simply recite the concept of processing withdrawal transaction request. The claims do not, for example, purport to improve the functioning of the computer itself. Nor do they effect an improvement in any other technology or technical field. The use of a processor, processing circuit, public and private key pair, pooled account database and processor-readable medium as tools to implement the abstract idea does not render the claim patent eligible because it does not provide meaningful limitations beyond generally linking the use of an abstract idea to a particular technological environment and requires no more than a computer performing functions that correspond to acts required to carry out the abstract idea. 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 US Application Publication US20150332256A1 (“Minor”) in view of US Application Publication US20150310424A1 (“Myers”).
