Office Action

§101
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 . DETAILED ACTION Status of Claims This action is in reply to the response filed on 4th of February 2026. Claim 1 was amended. Claims 2-18 were newly added. Claims 1-18 are currently pending and have been examined. Response to Arguments Applicant's arguments filed 4th of February 2026 have been fully considered but they are not persuasive. With regard to the limitations of claims 1-18, Applicant argues “…improves the operations of the computing device by increasing the speed at which trades with price ranges are reviewed by the trader and executed…the claimed invention is an improvement in technology, and does not merely invoke computers as a tool for performing an abstract idea.” The Examiner respectfully disagrees. Currently, applicant is merely reciting the trading process in the amended claims. It might be an improvement to the abstract idea itself but the examiner is unclear how it is improving the operations of the computing device. The examiner will maintain the rejection. 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 1-18 are rejected under 35 U.S.C. 101 because the claimed invention is directed to abstract idea without significantly more. The claims recite abstract idea of organizing human activities. This judicial exception is not integrated into a practical application and the claims do not include additional elements that are sufficient to amount to significantly more than the judicial exception. Analysis First of all, claims are directed to one or more of the following statutory categories: a process, a machine, a manufacture, and a composition of matter. For claim 1, the claim recites an abstract idea of “…receive from a computer of a first trader a first order to buy or sell a trading product having a first price and a first size; receive from a second trader, via an electronic device, a second order to buy or sell the trading product that is contra to the first order, the second order defining a second quantity and a price range of possible prices at which the second order can be executed, the price range comprising at least a second price, in which the second quantity of the trading product is reserved in an OMS of the second trader such that the second quantity of the second order is permitted by the OMS to be executed at any price within the price range; determine whether the first price of the first order is within the price range of the second order, in which the act of determining whether the first price of the first order is within the price range of the second order comprises determining that the first price of the first order is within the price range of the second order; and responsive to determining that the first price of the first order is within the price range of the second order, cause to be output to at least one other electronic device associated with the second trader, the least one other electronic device different from the electronic device, (1) the price of the first order and (2) an execution indicia selectable by the second trader to cause at least a portion of the second order to be executed against at least a portion of the first order, in which the first price of the first order and the execution indicia are not output or otherwise disclosed to the second trader prior to the act of determining that the first price of the first order is within the price range of the second order.” This is an abstract idea of a certain method of organizing human activity, since it recites a commercial or legal interactions, namely managing orders to buy or sell trading products. Besides reciting the abstract idea, the remaining claim limitations recite generic computer components/processes (e.g., processors, memory, a computer, electronic device, other electronic devices). “We conclude that claim 1 is “directed to a result or effect that itself is the abstract idea and merely invoke[s] generic processes and machinery” rather than “a specific means or method that improves the relevant technology.” Smart Sys. Innovations, LLC v. Chi. Transit Authority, 873 F.3d 1364, 1371 This recited abstract idea is not integrated into a practical application. In particular, the claim only recites generic computer components/processes (e.g., processors, memory, a computer, electronic device, other electronic devices) to receive/transmit/display(output) data (extra-solution activities) and perform the abstract idea mentioned above. (See at least MPEP 2016.05(g): CyberSource v. Retail Decisions, Inc., 654 F.3d 1366, 1375 (Fed. Cir. 2011); buySafe, Inc. v. Google, Inc., 765 F.3d 1350, 1355 (Fed. Cir. 2014); OIP Techs., Inc. v. Amazon.com, Inc., 788 F.3d 1359, 1363 (Fed. Cir. 2015); Ultramercial, Inc. v. Hulu, LLC, 772 F.3D 709, 715 (Fed. Cir. 2014); Electric Power Group, LLC v. Alstom S.A., 830 F.3d 1350, 1354-55 (Fed. Cir. 2016); Intellectual Ventures I LLC v. Erie Indem. Co., 850 F.3d 1315, 1328-29 (Fed. Cir. 2017); Ameranth, 842 F.3d at 1245, 120 USPQ2d at 1857; Trading Technologies v. IBG LLC, 921 F.3d 1084, 1093-94, 2019 USPQ2d 138290 (Fed. Cir. 2019)). The additional elements (e.g., processors, memory, a computer, electronic device, other electronic devices) are recited at a high-level of generality such that they amount to no more than mere instructions to apply the exception using generic computer components or merely uses a computer as a tool to perform an abstract idea. Accordingly, these additional elements do not integrate the abstract idea into a practical application because they do not impose any meaningful limits on practicing the abstract idea. Therefore, the claim is directed to an abstract idea. The claim does 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 elements - (e.g., processors, memory, a computer, electronic device, other electronic devices) amount to no more than mere instructions to apply the abstract idea using generic computer components or merely uses a computer as a tool to perform an abstract idea. In conclusion, merely “applying” the exception using generic computer components cannot provide an inventive concept. Therefore, the claim is not patent eligible under 35 USC 101. Again, the insignificant extra-solution activities mentioned above were re-evaluated in step 2B. The limitations do not amount to significantly more than the abstract idea because the courts found sending/receiving/displaying(outputting) of data to be well understood, routine, and conventional activities. (See at least MPEP 2016.05(g): CyberSource v. Retail Decisions, Inc., 654 F.3d 1366, 1375 (Fed. Cir. 2011); buySafe, Inc. v. Google, Inc., 765 F.3d 1350, 1355 (Fed. Cir. 2014); OIP Techs., Inc. v. Amazon.com, Inc., 788 F.3d 1359, 1363 (Fed. Cir. 2015); Ultramercial, Inc. v. Hulu, LLC, 772 F.3D 709, 715 (Fed. Cir. 2014); Electric Power Group, LLC v. Alstom S.A., 830 F.3d 1350, 1354-55 (Fed. Cir. 2016); Intellectual Ventures I LLC v. Erie Indem. Co., 850 F.3d 1315, 1328-29 (Fed. Cir. 2017); Ameranth, 842 F.3d at 1245, 120 USPQ2d at 1857; Trading Technologies v. IBG LLC, 921 F.3d 1084, 1093-94, 2019 USPQ2d 138290 (Fed. Cir. 2019)). Thus again, claims were not patent eligible under 35 USC 101. Similar arguments can be extended to independent claims 7 and 13. Dependent claims 2-6, 8-12, and 14-18 have been given the full two-part analysis, analyzing the additional limitations both individually and in combination. The dependent claims when analyzed individually and in combination, are also held be patent ineligible under 35 U.S.C. 101. For claims 2, 8, and 14, the additional limitations of these claims merely recite additional steps that amount to no more than insignificant extra-solution activity. The claims added “…at least one processor to continuously receive in real time, updated real time market information from a remote server.” The limitation of these claims fail to integrate the abstract idea into a practical application because these steps amount to no more than mere data gathering, which is insignificant extra-solution activity. (See at least MPEP 2016.05(g): CyberSource v. Retail Decisions, Inc., 654 F.3d 1366, 1375 (Fed. Cir. 2011); buySafe, Inc. v. Google, Inc., 765 F.3d 1350, 1355 (Fed. Cir. 2014); OIP Techs., Inc. v. Amazon.com, Inc., 788 F.3d 1359, 1363 (Fed. Cir. 2015); Ultramercial, Inc. v. Hulu, LLC, 772 F.3D 709, 715 (Fed. Cir. 2014); Electric Power Group, LLC v. Alstom S.A., 830 F.3d 1350, 1354-55 (Fed. Cir. 2016); Intellectual Ventures I LLC v. Erie Indem. Co., 850 F.3d 1315, 1328-29 (Fed. Cir. 2017); Ameranth, 842 F.3d at 1245, 120 USPQ2d at 1857; Trading Technologies v. IBG LLC, 921 F.3d 1084, 1093-94, 2019 USPQ2d 138290 (Fed. Cir. 2019)). For claims 3, 9, and 15, the recited limitations of these claims merely further narrow the abstract idea discussed above. These claims further add, “…comprises receiving a spread value, in which the price range comprises a range of prices between the following two values: (a) one of (1) a midpoint price of a National Best Bid and Offer (NBBO), (2) a best bid price of the NBBO, and (3) a best offer price of the NBBO; and (b) one of (1) the value of (a) increased by the spread value if the second order is a bid, and (2) the value of (a) decreased by the spread value if the second order is an offer.” The limitations of these claims fail to integrate the abstract idea into a practical application because these claims do not introduce additional elements other than the generic components discussed above. These dependent claims, therefore, also amounts to merely using a computer, in its ordinary capacity, as a tool to perform the abstract idea. Finally, the additional recited limitations of these dependent claims fail to establish that the claims provide an inventive concept because claims that merely use a computer, in its ordinary capacity, as a tool to perform the abstract idea cannot provide an inventive concept. For claims 4, 10, and 16, the recited limitations of these claims merely further narrow the abstract idea discussed above. These claims further add, “…wherein the price range comprises a variable price range that is defined relative to at least one reference price that is changeable over time, such that the price range changes over time as the at least one reference price changes.” The limitations of these claims fail to integrate the abstract idea into a practical application because these claims do not introduce additional elements other than the generic components discussed above. These dependent claims, therefore, also amounts to merely using a computer, in its ordinary capacity, as a tool to perform the abstract idea. Finally, the additional recited limitations of these dependent claims fail to establish that the claims provide an inventive concept because claims that merely use a computer, in its ordinary capacity, as a tool to perform the abstract idea cannot provide an inventive concept. For claims 5, 11, and 17, the recited limitations of these claims merely further narrow the abstract idea discussed above. These claims further add, “…wherein the at least one reference price comprises at least one of (1) a best bid price, (2) a best offer price, (3) a midpoint between a best bid price and best offer price, or (4) an indicative net asset value (INAV).” The limitations of these claims fail to integrate the abstract idea into a practical application because these claims do not introduce additional elements other than the generic components discussed above. These dependent claims, therefore, also amounts to merely using a computer, in its ordinary capacity, as a tool to perform the abstract idea. Finally, the additional recited limitations of these dependent claims fail to establish that the claims provide an inventive concept because claims that merely use a computer, in its ordinary capacity, as a tool to perform the abstract idea cannot provide an inventive concept. For claims 6, 12, and 18, the recited limitations of these claims merely further narrow the abstract idea discussed above. These claims further add, “…wherein the second order is received before the first order.” The limitations of these claims fail to integrate the abstract idea into a practical application because these claims do not introduce additional elements other than the generic components discussed above. These dependent claims, therefore, also amounts to merely using a computer, in its ordinary capacity, as a tool to perform the abstract idea. Finally, the additional recited limitations of these dependent claims fail to establish that the claims provide an inventive concept because claims that merely use a computer, in its ordinary capacity, as a tool to perform the abstract idea cannot provide an inventive concept.
