`in combination with
`Tanenbaum96 in further combination with Stevens2 ......................... 61
`10.1.1.
`[1.P] A method for network communication by a host
`computer having a network interface that is connected
`to the host by an input/output bus, the method
`comprising............................................................................ 61
`[1.1] running, on the host computer, a protocol
`processing stack including an Internet Protocol (IP)
`layer and a Transmission Control Protocol (TCP)
`layer, with an application layer running above the
`TCP layer; ............................................................................ 63
`[1.2] initializing, by the host computer, a TCP
`connection that is defined by source and destination
`IP addresses and source and destination TCP ports; ........... 68
`[1.3] receiving, by the network interface, first and
`second packets, wherein the first packet has a first
`TCP header and contains first payload data for the
`application, and the second packet has a second TCP
`header and contains second payload data for the
`application; ........................................................................... 72
`[1.4] checking, by the network interface, whether the
`packets have certain exception conditions, including
`checking whether the packets are IP fragmented,
`checking whether the packets have a FIN flag set, and
`checking whether the packets are out of order; ................... 74
`[1.5] if the first packet has any of the exception
`conditions, then protocol processing the first TCP
`header by the protocol processing stack; ............................. 76
`[1.6] if the second packet has any of the exception
`conditions, then protocol processing the second TCP
`header by the protocol processing stack; ............................. 77

`host computer, such that the payload data is stored in
`the buffer in order and without any TCP header stored
`between the first payload data and the second payload
`data. ...................................................................................... 78

`payload data and the second payload data together in a
`buffer of the host computer is performed by a direct
`memory access (DMA) unit of the network interface. ........ 83

`of the packets with the source and destination IP
`addresses and source and destination TCP ports that
`define the TCP connection. .................................................. 84

`connection and to check whether the packets have
`certain exception conditions, including whether the
`packets are IP fragmented, have a FIN flag set, or are
`out of order, the network interface having logic that
`directs any of the received packets that have the
`exception conditions
`to
`the protocol stack for
`processing, and directs the received packets that do
`not have any of the exception conditions to have their
`headers removed and their payload data stored

`
`INTRODUCTION
`Pursuant to 35 U.S.C. §§ 311-319 and 37 C.F.R. §§ 42.1-.80, 42.100-.123,
`
`Intel Corporation (“Petitioner”) respectively hereby petitions the Patent Trial and
`
`Appeal Board to institute an inter partes review of claims 1, 3, 6-8, 17, 19, and 21-
`
`22 of U.S. Patent No. 8,805,948, titled “Intelligent Network Interface System and
`
`Method for Protocol Processing” (Ex.1001, the “948 Patent”), and cancel those
`
`claims as unpatentable.
`
`On November 22, 2017, the Board denied institution in IPR2017-01395
`
`based on a procedural ground regarding whether a reference was prior art, which
`
`was based on a petition also filed by Petitioner Intel. Specifically, the Board
`
`denied institution on the basis that the primary reference in Intel’s petition,
`
`Stevens2, was not shown to be a “printed publication.” IPR2017-01395, Paper 8 at
`
`8. The Board noted that it was Petitioner’s burden to prove that it was prior art.
`
`Id. at 3. It then found that Exhibit 1063, an affidavit from Pamela Stansbury, an
`
`employee of the Original Cataloging Unit of the Cornell University Library, to be
`
`insufficient to support the availability of Stevens2. Id. at 6.
`
`Respectfully, Stevens2 is a well-known and respected text book that bears a
`
`copyright date of 1995. Petitioner’s expert attested that persons of ordinary skill in
`
`the art were aware of the Stevens2 reference before the priority date of the instant
`
`patent. Ex. 1003 Petitioner further provided a declaration, under oath, from Ms.
`
`
`
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 8,805,948
`
`Stansbury, an employee of the Original Cataloguing Unit of the Cornell University
`
`Library, who attested that the Cornell University Library maintains a copy of the
`
`Stevens2 reference and to the best that she can determine, Stevens2 was publicly
`
`available at the Cornell University Library as of April 7, 1995. Ex. 1063.
`
`Petitioner also noted that the prior art status of the Stevens2 reference is further
`
`corroborated by
`
`the provisional application, U.S. Provisional Application
`
`60/061809, that led to the instant patent. Ex. 1031. U.S. Provisional Application
`
`60/061809 specifically references Stevens2, “According to W. Richards Stevens
`
`and Gary Write in their book ‘TCP/IP Illustrated Volume2’, TCP operates without
`
`experiencing any exceptions between 97 and 100 percent of the time in local area
`
`networks.” Ex. 1063.
`
`Respectfully, Petitioner believed that Exhibit 1063 in the prior petition
`
`established a prima facie case that Stevens2 was a prior art printed publication and
`
`that Petitioner would be permitted to respond to Patent Owner’s challenge to
`
`Stevens2’s status as prior art by offering supplemental evidence pursuant to 37
`
`C.F.R. § 42.64(b).
`
`Nonetheless, Petitioner submits further evidence that Stevens2 is indeed
`
`prior art. Specifically, Petitioner submits 10 references that pre-date the priority
`
`date of the instant patent that have cited to Stevens2. Petition further submits
`
`
`
`-2-
`
`
`
`Petition for Inter Partes Review of U.S. Patent No. 8,805,948
`
`evidence that the 2010 reprinting relied on by Petitioner is identical to the Ex. 1096
`
`that has a 1996 printing date.
`
`More specifically, the challenged claims relate to the well-known prior art
`
`technique of i) conditionally offloading host protocol processing onto a network
`
`interface device (also known as a network adapter) (“NIC”) for normal processing
`
`and ii) copying data from a NIC to the host computer’s memory. Effectively,
`
`independent method claim 1 covers what was known in the prior art as fast path
`
`processing of packets on a NIC, where packets eligible for simple protocol
`
`processing bypass the normal protocol processing on the host and the recovered
`
`data (after stripping off the headers) is stored in host memory. Independent claim
`
`17 covers an apparatus which performs these methods. Dependent claims 3, 6-8,
`
`19, and 21-22 add well-known limitations associated with fast path TCP
`
`processing. This Petition demonstrates that each of these claims is unpatentable.
