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 .
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
This application currently names joint inventors. 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. 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.
Information Disclosure Statement
The Information Disclosure Statement filed on 29 January 2025, 4 February 2025, 4 March 2025, and 18 March 2025 have been considered by the examiner.
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 § 2146 et seq. 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 filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.
The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual 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.

Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 18-20 rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claim 18 recites, “preventing the virtual memory page from being mapped to first memory of the memory module for duration of the remote direct memory access network interface card transferring the data between the remote apparatus and the memory module.” It is unclear how this limitation is to be interpreted. In the parent application (18,645,761), the memory module contains a first memory and a second memory. The memory page is prevented from mapping to the first memory and is mapped to the second memory fur the duration of the transferring. In the instant application there is only one memory recited a being part of the memory module (e.g. first memory).
Claims 19 and 20 rejected as depending from claim 18.
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)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claim(s) 1-3, 11, and 12 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Cayton et al. (Pub. No. US 2019/0102287).
Claim 1:
Cayton et al. disclose a device, comprising:
remote direct memory access network interface card configured to transfer data between a remote apparatus connected to the computer network and a memory module configured on a memory bus in response to a command received via a peripheral interconnect [figs. 1, 7; par. 0021-0022, 0064 – A write may be received over the system interface for a network connected device. The write data may be stored in the Local NVM. (“The system memory 86 and RPDMA device 50 may be on a same computing device, such as a server. In some embodiments, the system memory 86 and RPDMA device 50 may in separated computing devices, such as different servers. For example, an operating system may be present the system memory 86 and local NVM 70 to the local machine as local but virtual resources. Behind that virtual implementation the system memory 86 and local NVM 70 may be on different systems.” … “For example, the local NVM logic 82 may write into and read from the local NVM 70. If another device, node or machine is to store data via the RPDMA device 50, the RPDMA device 50 determines which memory 70, 80, 86A, 86B to store the data within, and then stores the data. Therefore, the RPDMA device 50 may provide a consistent interface between local and remote memory storage operations. The RPDMA device 50 may include one form factor comprising both the RNIC 72 and the local NVM 70.” … “The write operation may originate with a device (not illustrated) of the network storage architecture 60 or an application to trigger the write operation. For example, if a specific application is launched, data associated with that application may be written into the local NVM 70. That is, an application may determine that data should be moved from the system memory 86 to the local NVM 70 because the data will be used in network operations. A write request for data stored in system memory 86 is received as illustrated by flow 400, and is detected by the RDMA network logic 66. The RDMA network logic 66 may access the memory region table 68 as illustrated by flow 402, to determine which memory region to read the data from, and which memory region to write the data into.”)].
Claim 2 (as applied to claim 1 above):
Cayton et al. disclose the device, further comprising:
the memory bus [fig. 1 – connection to local NVM]; and
a memory module connected to the memory bus [fig. 1 – local NVM].
Claim 3 (as applied to claim 2 above):
Cayton et al. disclose the device, further comprising:
the peripheral interconnect [fig. 1; par. 0021 - System interface. (“To read/write to the system memory 86, the RPDMA device 50 may need to utilize system interface 84. The system interface 84 may be a PCIe interface which may transmit and receive data over a PCIe bus, or a double-data-rate interface.”)]; and
a host system connected to the memory bus and connected to the peripheral interconnect to send the command [fig. 1; par. 0021 - “The system memory 86 and RPDMA device 50 may be on a same computing device, such as a server. In some embodiments, the system memory 86 and RPDMA device 50 may in separated computing devices, such as different servers. For example, an operating system may be present the system memory 86 and local NVM 70 to the local machine as local but virtual resources. Behind that virtual implementation the system memory 86 and local NVM 70 may be on different systems.”].
Claim 11:
Cayton et al. disclose a method, comprising:
receiving, in a remote direct memory access network interface card via a peripheral interconnect, a command [figs. 1, 7; par. 0021-0022, 0064 – A write may be received over the system interface for a network connected device. (“The system memory 86 and RPDMA device 50 may be on a same computing device, such as a server. In some embodiments, the system memory 86 and RPDMA device 50 may in separated computing devices, such as different servers. For example, an operating system may be present the system memory 86 and local NVM 70 to the local machine as local but virtual resources.

Therefore, the RPDMA device 50 may provide a consistent interface between local and remote memory storage operations. The RPDMA device 50 may include one form factor comprising both the RNIC 72 and the local NVM 70.” … “The write operation may originate with a device (not illustrated) of the network storage architecture 60 or an application to trigger the write operation. For example, if a specific application is launched, data associated with that application may be written into the local NVM 70. That is, an application may determine that data should be moved from the system memory 86 to the local NVM 70 because the data will be used in network operations. A write request for data stored in system memory 86 is received as illustrated by flow 400, and is detected by the RDMA network logic 66. The RDMA network logic 66 may access the memory region table 68 as illustrated by flow 402, to determine which memory region to read the data from, and which memory region to write the data into.”)]; and
transferring, in response to the command, data between a remote apparatus connected to a computer network and a memory module configured on a memory bus [figs. 1, 7; par. 0021-0022, 0064 – A write may be received over the system interface for a network connected device. The write data may be stored in the Local NVM. (“The system memory 86 and RPDMA device 50 may be on a same computing device, such as a server. In some embodiments, the system memory 86 and RPDMA device 50 may in separated computing devices, such as different servers.

The RDMA network logic 66 may access the memory region table 68 as illustrated by flow 402, to determine which memory region to read the data from, and which memory region to write the data into.”)].
Claim 12 (as applied to claim 11 above):
Cayton et al. disclose,
wherein a host system connected to the memory bus and connected to the peripheral interconnect is configured to send the command [fig. 1; par. 0021 - “The system memory 86 and RPDMA device 50 may be on a same computing device, such as a server. In some embodiments, the system memory 86 and RPDMA device 50 may in separated computing devices, such as different servers. For example, an operating system may be present the system memory 86 and local NVM 70 to the local machine as local but virtual resources. Behind that virtual implementation the system memory 86 and local NVM 70 may be on different systems.”].
Claim(s) 4 and 13 is/are rejected under 35 U.S.C. 103 as being unpatentable over Cayton et al. (Pub. No. US 2019/0102287) as applied to claim 3 and 12 above, respectively, and further in view of Makhervaks et al. (Pub. No. US 2018/0032249).
Claim 4 (as applied to claim 3 above):
Cayton et al. disclose all the limitations above but do not specifically disclose,
wherein the host system is configured to run a driver programmed for the remote direct memory access network interface card and configured to generate the command.
In the same field of endeavor, Makhervaks et al. disclose,
wherein the host system is configured to run a driver programmed for the remote direct memory access network interface card and configured to generate the command [fig. 13; par. 0091 – “The host computer 400 includes an RNIC driver 476, RNIC queues 477, MSIX 478 and an RNIC device interface 479.”].
It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify the invention of Cayton et al. to include device drivers, as taught by Makhervaks et al., in order to allow the host to communicate with the device by translating the commands into instructions that the device can understand.
Claim 13 (as applied to claim 12 above):
Claim 13, directed to a method, is rejected for the same reasons set forth in the rejection of claim 4 above.
Claim(s) 5 is/are rejected under 35 U.S.C. 103 as being unpatentable over Cayton et al. (Pub. No. US 2019/0102287) in view of Makhervaks et al. (Pub. No. US 2018/0032249) as applied to claim 4 above, and further in view of Schmidt et al. (Pub. No. US 2013/0332696).
Claim 5 (as applied to claim 4 above):
Cayton et al. and Makhervaks et al. disclose all the limitations above but do not specifically disclose,
wherein the remote direct memory access network interface card is configured to implement single root input/output virtualization to provide a physical function and a plurality of virtual functions.
In the same field of endeavor, Schmidt et al. disclose,
wherein the remote direct memory access network interface card is configured to implement single root input/output virtualization to provide a physical function and a plurality of virtual functions [par. 0003 – “The existing solution allows the hypervisor to exploit the virtualization provided by the RNIC adapter vendor (referred to as Single Root-I/O Virtualization or SR-IOV). The adapter virtualization requires that the hypervisor use the hardware adapter and the PCIe interface for connectivity within a single platform. This solution can become costly and induce bottlenecks within the platform.”].
It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify the combined teachings of Cayton et al. and Makhervaks et al. to include single root input/output virtualization, as taught by Schmidt et al., in order to enable efficient sharing of a PCIe resource.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Gupta et al. (Pub. No. US 2013/0232215) disclose, “The prefetching agent monitors data storage access requests, including data reads, data writes, and other storage operations, to determine the association between requested storage blocks and the corresponding high-level data structure entities, such as files, directories, or database elements, and/or other attributes useful for predicting future storage requests, such as the identity and/or type of the application requesting storage block access or other applications on the storage client, operating modes of the requesting application, virtual machine or other virtualization information, and any user or application inputs or outputs.” [par. 0015]
