`Petition for Post Grant Review
`Patent No. 10,003,553
`
`
`
`I.
`
`INTRODUCTION
`Flex Logix Technologies, Inc. (“Petitioner”) requests post grant review
`
`(“PGR”) of claims 1-7, 9-15, and 17-19 (“the challenged claims”) of U.S. Patent
`
`No. 10,003,553 (“the ’553 patent”) (Ex. 1001), which, according to PTO records,
`
`is assigned to Konda Technologies, Inc. (“Patent Owner” or “PO”). For the
`
`reasons below, the challenged claims should be found unpatentable and canceled.
`
`The ’553 patent purports to be part of a family of applications based on U.S.
`
`Provisional Patent Application 61/531,615 (“the ’615 provisional application”)
`
`filed September 7, 2011. Prior to filing the ’615 provisional application to which
`
`the ’553 patent purports to claim priority, PO filed numerous patent applications
`
`concerning similar subject matter, and many of those earlier-filed applications are
`
`listed as related applications in the ’553 patent. (Ex. 1001, 1:8-2:62.) During
`
`prosecution of applications claiming priority to the ’615 provisional application,
`
`those earlier filed applications were relied on by the PTO for claim rejections.
`
`In addressing those previous rejections based on its own earlier-filed subject
`
`matter, PO argued that the rejected claims included “rings” that were not disclosed
`
`in the earlier-filed applications. As demonstrated below, the claims of the ’553
`
`patent do not include any “rings,” and the challenged claims of the ’553 patent are
`
`anticipated or rendered obvious by PO’s earlier-filed applications.

`Patent No. 10,003,553
`
`
`
`
`Similarly, during prosecution of an earlier-filed related application, PO
`
`added limitations to pending claims to overcome rejections based on Wong.
`
`However, the claims of the ’553 patent do not include the features PO previously
`
`added in order to overcome Wong, and, as demonstrated in a concurrently filed
`
`petition, Wong anticipates the challenged claims of the ’553 patent.
`
`II. MANDATORY NOTICES UNDER 37 C.F.R. § 42.8
`A. Real Parties-in-Interest
`Petitioner identifies Flex Logix Technologies, Inc. as the real party-in-
`
`interest.

`PO has asserted the ’553 patent against Petitioner in Konda Technologies
`
`Inc. v. Flex Logix Technologies, Inc., No. 5:18-cv-07581-LHK (N.D. Cal.). PO
`
`has also asserted U.S. Patent Nos. 8,269,523 (“the ’523 patent”), 8,898,611 (“the
`
`’611 patent”), 9,529,958 (“the ’958 patent”), and 10,050,904 (“the ’904 patent”) in
`
`the foregoing district court litigation.
`
`2.

`
`III. PAYMENT OF FEES UNDER 37 C.F.R. § 42.15(a)
`The PTO is authorized to charge all fees due at any time during this
`
`proceeding, including filing fees, to Deposit Account No. 50-2613.
`
`IV. TIME FOR FILING UNDER 37 C.F.R. § 42.202
`The ’553 patent issued on June 19, 2018, and this Petition is being timely
`
`filed no later than the date that is nine months after the date of the grant of the ’553
`
`patent.
`
`V. GROUNDS FOR STANDING UNDER 37 C.F.R. § 42.204(a)
`Petitioner certifies that the ’553 patent is available for PGR and Petitioner is
`
`not barred or estopped from requesting PGR on the grounds identified herein.
`
`As discussed below in Section IX, the ’553 patent is eligible for PGR
`
`because it has at least one claim that is not entitled to a pre-AIA filing date.
`
`VI. PRECISE RELIEF REQUESTED AND GROUNDS RAISED
`A. Claims for Which Review is Requested
`Petitioner respectfully requests review of claims 1-7, 9-15, and 17-19
`
`(“challenged claims”) of the ’553 patent, and cancellation of these claims as

`

`Petition for Post Grant Review
`Patent No. 10,003,553
`
`
`
`unpatentable.
`
`B.
`Statutory Grounds of Challenge
`The challenged claims should be canceled as unpatentable on the following
`
`grounds:
`
`Ground 1: Claims 1-7, 9-15, and 17-19 are unpatentable under AIA 35
`
`U.S.C. § 102(a)(1) as being anticipated by Published PCT Application No. WO
`
`2008/109756 (“Konda ’756 PCT”) (Ex. 1009).
`
`Ground 2: Claims 1-7, 9-15, and 17-19 are unpatentable under AIA 35
`
`U.S.C. § 103 as obvious over Konda ’756 PCT in view of U.S. Patent No.
`
`6,940,308 to Wong (“Wong”) (Ex. 1008).
`
`The earliest possible priority date for the ’553 patent is September 7, 2011,
`
`which corresponds to the filing date of the ’615 provisional application. (Ex. 1007,
`
`90). Konda ’756 PCT published September 12, 2008, and Wong issued on
`
`September 6, 2005. Thus, Konda ’756 PCT and Wong are prior art at least under
`
`AIA U.S.C. § 102(a)(1) with respect to the ’553 patent.
`
`Konda ’756 PCT was not considered by the Patent Office during
`
`prosecution. Wong was considered by the Patent Office during prosecution.
`
`However, Petitioner presents Wong in a new light never considered by the Office.
`
`For example, the prosecution history of the ’553 patent does not include

`
`
`
`substantive discussion of Wong or any other prior art reference relating to
`
`patentability of the ’553 patent claims. Indeed, there were no claim rejections
`
`based on any prior art. Here, Petitioner presents testimony from R. Jacob Baker,
`
`Ph.D., P.E. (Ex. 1002), an expert in the field of the ’553 patent (Ex. 1002, ¶¶3-13,
`
`18; Ex. 1003), who confirms that the relevant teachings of Konda ’756 PCT and
`
`Wong disclose or suggest what is claimed by challenged claims 1-7, 9-15, and 17-
`
`19 of the ’553 patent. (See Ex. 1002, ¶¶86-187; see also infra Section XIII.)
`
`As such, any consideration of Wong by the Patent Office during prosecution
`
`of the ’553 patent should not preclude the Board from considering and adopting the
`
`ground in this petition.
`
`VII. LEVEL OF ORDINARY SKILL IN THE ART
`A person of ordinary skill in the art (“POSITA”) at the time of the alleged
`
`invention of the ’553 patent would have had a master’s degree in electrical
`
`engineering or a similar field, and at least two to three years of experience with
`
`integrated circuits and networks. (Ex. 1002, ¶18.) More education can supplement
`
`practical experience and vice versa. (Id.)

`
`
`
`VIII. BACKGROUND
`The ’553 patent generally relates to switching networks that can be used to
`
`route signals between logic blocks included on an integrated circuit device such as
`
`an FPGA. (Ex. 1002, ¶¶20-50.)
`
`A. The ’553 Patent
`The ’553 patent, which matured from the U.S. Application No. 15/140,470
`
`(“the ’470 application”), acknowledges that multi-stage hierarchical networks were
`
`known and used in many applications at the time of the alleged invention, such as
`
`in “FPGA routing of hardware designs.” (Ex. 1001, 2:66-3:1, 4:47-48.) The ’553
`
`patent states that known VLSI (very large scale integration) layouts for integrated
`
`circuits with such networks, such as the Benes network disclosed by Wong (Ex.
`
`1008) are “inefficient and complicated.” (Id., 3:2-4, 3:30-36.) For instance, the
`
`’553 patent contends that prior art network layouts “require large area to
`
`implement the switches on the chip, large number of wires, longer wires, with
`
`increased power consumption, increased latency of the signal which effect the
`
`maximum clock speed of operation.” (Id., 3:43-48; Ex. 1002, ¶¶31-32 (citing Ex.
`
`1040).)
`
`The ’553 patent alleges to disclose “[s]ignificantly optimized multi-stage
`
`networks, useful in wide target applications” where the “optimized multi-stage
`
`
`
`

`Patent No. 10,003,553
`
`
`
`networks in each block employ several rings of stages of switches with inlet and
`
`outlet links.” (Ex. 1001, 3:58-67 (emphasis added).) As discussed below, PO
`
`touted this concept of “rings” in the ’553 patent family as an important distinction
`
`over PO’s earlier patent applications, and, not surprisingly, the claims in the
`
`applications to which the ’553 patent claims priority (and the originally filed
`
`claims in the ’470 application itself) all include the “ring” concept. However,
`
`these “rings”—which (i) the ’553 patent describes as an important aspect of the
`
`alleged optimizations to the prior art multi-stage hierarchical networks, and (ii) PO
`
`touted as an important distinction over PO’s other applications—are not recited in
`
`the claims of the ’553 patent. (Ex. 1002, ¶¶33-38.)
`
`First, the ’553 patent’s disclosure emphasizes “rings.” Each of figures 1-15
`
`of the ’553 patent illustrates, describes, or relates to the use of “rings” in a “multi-
`
`stage hierarchical network.” (Ex. 1002, ¶33 (citing Ex. 1001, 4:42-6:22, FIGs. 1-
`
`15, 8:56-9:3, 33:26-48).) Annotated figure 1 of the ’553 patent below shows two
`
`such “rings”:

`(Ex. 1001, FIG.1 (annotated); Ex. 1002, ¶38.) Similarly, the figures that depict
`
`example “stages” in the ’553 patent are described as illustrating portions of a
`
`“ring.” (Ex. 1001, 4:56-5:3, 5:32-6:6, FIGs. 2A-2E, 9A-11C.)
`
`Second, during prosecution of U.S. Application No. 14/199,168 (“the ’168
`
`application”), which issued as U.S. Patent No. 9,374,322 (“the ’322 patent”) (see
`
`supra Section II.B.2), PO explicitly defined “rings” and argued that the inclusion
`
`of such rings was a “key difference[]” with respect to PO’s earlier alleged
`
`inventions disclosed in U.S. Patent No. 8,898,611 (“the ’611 patent”).

`Patent No. 10,003,553
`
`
`
`
`Current application discloses stages in rings where
`forward connecting links are feedback into backward
`connecting links through one or more multiplexers and
`also backward connecting links are feedback into
`forward connecting
`links
`through one or more
`multiplexers, where US Patent No. 8,898,611 discloses
`folded and butterfly fat tree networks where in each stage
`only forward connecting
`links are feedback
`into
`backward connecting links . . . This is one of the key
`differences in the current invention. . .
`
`(Ex. 1005, 97-98 (emphases added).)
`
`The ring concept disclosed in the current application is
`not a true ring, the term ring is used in the current
`invention since in each stage backward connecting links
`are feedback to forward connecting links and vice versa
`as opposed to only a U-turn in original multi-stage
`networks.
`
`(Id., 101; see also Ex. 1001, 2:33-38; Ex. 1002, ¶¶39-42.)
`
`The claims of the ’322 patent all include this “ring” concept. (Ex. 1035,
`
`47:42-51:3.) Similarly, all of the claims of PCT Application No. PCT/US12/53814
`
`(“the ’814 PCT application”) to which the ’168 application claims priority also
`
`
`
`

`Patent No. 10,003,553
`
`
`
`include this “ring” concept. (Ex. 1006, 79-82 (1:3-4:23).)1.) Indeed, the originally
`
`filed claims in the ’470 application also include “rings” (Ex. 1004, 286-292) and
`
`further include specific limitations consistent with the definition PO provided for a
`
`“ring” during prosecution of the ’168 application. (Id., 287 (82:13-18)2; Ex. 1002,
`
`¶¶39-41.)
`
`But in contrast to the originally filed claims in the ’470 application, the
`
`issued claims in the ’322 patent, and the claims in the 814 PCT application, new
`
`claims 21-40 that were added by amendment during prosecution of the ’470
`
`application and that issued as claims 1-20 in the ’553 patent do not include
`
`“rings.” (Ex. 1004, 77-84.)3 In other words, issued claims 1-20 of the ’553 patent
`
`
` The ’814 PCT application as filed had errors in pagination such that the section
`
` 1
`
`that includes the claims restarts the pagination at page 1. Therefore, citations to
`
`the ’814 PCT application include both a page number for the exhibit as well as the
`
`page and line numbers printed on the page identified within the exhibit.
`
`2 When appropriate, citations to the as-filed ’470 application include page and line
`
`numbers corresponding to the application.

`
`claims would be reviewed for their compliance with 35 U.S.C. § 112, the claims

`
`
`
`are missing a feature that is not only highlighted in the specification as an alleged
`
`fundamental point of novelty, but was in fact touted by PO as a “key difference[]”
`
`between the disclosure of the ’553 patent family and another patent family
`
`belonging to PO. (Ex. 1002, ¶42.)
`
`B. Material Incorporated by Reference in the ’553 Patent
`The ’553 patent attempts to incorporate by reference a list of more than 20
`
`patents and patent applications. (Ex. 1001, 1:8-2:62; Ex. 1002, ¶37.) However,
`
`the incorporations by reference of these patents and applications provide no
`
`“detailed particularity [regarding] what specific material” they incorporate and do
`
`not “clearly indicate where that material is found” in the patents and applications.
`
`Cook Biotech Inc. v. Acell, Inc., 460 F. 3d 1365, 1376 (Fed. Cir. 2006); see also
`
`Paice LLC v. Ford Motor Co., 881 F.3d 894, 906-07 (Fed. Cir. 2018) (“To
`
`incorporate material by reference, the host document must identify with detailed
`
`particularity what specific material it incorporates and clearly indicate where that
`
`material is found in the various documents.”) (internal citations and quotation
`
`
`were subsequently allowed without any further rejections. (Ex. 1004, 51, 25-32.)
`
`The issued claims, however, do not comply with the requirements of 35 U.S.C. §
`
`112, as demonstrated in the concurrently filed PGR petition.

`
`
`
`marks omitted). Indeed, even when material is properly incorporated, “[i]t is not
`
`sufficient for purposes of the written description requirement of § 112 that the
`
`disclosure, when combined with the knowledge in the art, would lead one to
`
`speculate as to the modifications that the inventor might have envisioned, but
`
`failed to disclose.” D Three Enters., LLC v. Sunmodo Corp., 890 F.3d 1042, 1050
`
`(Fed. Cir. 2018) (internal citation omitted).
`
`The ’553 patent simply identifies several patents and patent applications and
`
`states that the material is incorporated in its entirety without specifying any
`
`particular portions of the documents as being relevant. (Ex. 1001, 1:8-2:62) Cook
`
`Biotech Inc., 460 F. 3d at 1376; see also Nautilus, Inc. v. Icon Health & Fitness
`
`Inc., IPR2017-01408, 2018 WL 6318050, at *20 (PTAB Dec. 3, 2018) (allowing
`
`incorporation by reference where the incorporating language provided detail
`
`regarding what was disclosed in the incorporated by reference). Moreover, many,
