`
`INTRODUCTION
`
`VirnetX Inc. (“Patent Owner”), the owner of U.S. Patent No. 7,921,211 (“the ’211 patent’),
`
`hereby respondsto the Office Action (“Office Action” or “OA”) and Order granting reexamination
`
`(“Order”) mailed on January 18, 2012, in the above-identified reexamination proceeding, which was
`
`initiated by Third-Party Requester, Apple Inc. (“Requester”), on October 18, 2011 (“the Request” or
`
`“Req.”). Patent Owneris grateful for the one-month extension of time to respond, extending the time
`
`for reply to April 18, 2012. The Examiner adoptedall thirty-five issues the Requester identified.
`
`The patent at issue in this reexamination, the ’211 patent, is part of a family of patents
`
`(“Munger patent family”) that stems from U.S. provisional application nos. 60/106,261 (“the °261
`
`application”), filed on October 30, 1998, and 60/137,704 (‘the ’704 application”), filed on June 7,
`
`1999. The ’211 patent is a continuation of U.S. application no. 10/714,849, filed November 18,
`
`2003, (now U.S. Patent No. 7,418,504, “the °504 patent”). The 504 patent is a continuation of U.S.
`
`application no. 09/558,210 (“the °210 application”), filed April 26, 2000, (now abandoned), whichis
`
`a continuation-in-part of U.S. application no. 09/504,783 (now U.S. Patent No. 6,502,135, “the ’135
`
`patent”). The °135 patent is a continuation-in-part of U.S. application no. 09/429,643 (now U.S.
`
`Patent No. 7,010,604, “the ’604 patent”), which claimspriority to the °261 and ’704 applications.
`
`The Mungerpatent family discloses numerous inventions relating to secure communications.
`
`Patents in this family have been subject to several reexamination proceedings and district court
`
`three other patents from the family were asserted in an action against
`For instance,
`actions.
`Microsoft Corporation in the Eastern District of Texas.’ The jury found the asserted claimswillfully
`
`infringed and not invalid and awarded VimetX over one hundred million dollars in damages. (Ex. A-
`
`1 at 2.) Microsoft also sought reexamination of two of the patents, but all claims were confirmed
`
`during those proceedings.
`
`(See control nos. 95/001,269 and 95/001,270.) And just recently, the
`
`Office denied a request for reexamination of one of the patents in the Munger patent family.
`
`(Order
`
`in control no. 95/001,792.)
`
`Given that the validity of the patents in the Munger patent family has now been tested
`
`multiple times, and for the other reasons set forth below, including that the asserted references do not
`
`disclose or suggest
`
`the combination of features recited in the claims, Patent Owner requests
`
`' One of these patents, U.S. Patent No. 6,839,759, was asserted initially but was dropped
`from this case beforetrial.

`Control No. 95/001,789
`
`reconsideration and withdrawal of all the rejections in the Office Action and confirmation of the
`
`patentability of all of the claims of the ’211 patent.
`
`Patent Owner’s statements below are supported, where indicated, by an expert Declaration of
`
`Angelos D. Keromytis, Ph.D. (“Keromytis Decl.”) and a Declaration of Dr. Robert Dunham Short III
`
`(“Short Decl.”).
`
`A.
`
`Applicable Legal Standards
`
`1.
`
`The Law of Anticipation
`
`“A claim is anticipated only if each and every element as set forth in the claim is found,
`
`either expressly or inherently described, in a single prior art reference.” Verdegaal Bros. v. Union
`
`Oil Co. of Cal., 814 F.2d 628, 631, 2 U.S.P.Q.2d 1051, 1053 (Fed. Cir. 1987).
`
`“The identical
`
`invention must be shown in as complete detail as is contained in the ... claim.” Richardson v.
`
`Suzuki Motor Co., 868 F.2d 1226, 1236, 9 U.S.P.Q.2d 1913, 1920 (Fed. Cir. 1989). Although
`
`identity of terminology is not required, the elements must be arranged as required by the claim. Jn re
`
`Bond, 910 F.2d 831, 15 U.S.P.Q.2d 1566 (Fed. Cir. 1990). Thus, “unless a reference discloses within
`
`the four corners of the documentnot only all of the limitations claimed but also all of the limitations
`
`arranged or combined in the same way asrecited in the claim, it .
`
`.
`
`. cannot anticipate under 35
`
`U.S.C. § 102.” Net Moneyln, Inc. v. Verisign, Inc., 545 F.3d 1359, 1369 (Fed. Cir. 2008).
`
`2.
`
`The Law of Obviousness
`
`A claim can only be rejected as being obvious if the differences between it and the prior art
`
`“are such that the subject matter as a whole would have been obviousat the time the invention was
`
`made to a person having ordinary skill in the art.” See 35 U.S.C. § 103(a) (1994); Graham v. John
`
`Deere Co., 383 U.S. 1, 13-14 (1966). The ultimate determination of whether an invention is obvious
`
`is a legal conclusion based on underlying factual inquiries including:
`
`(1) the scope and content of the
`
`prior art; (2) the level of ordinary skill in the art; (3) the differences between the claimed invention
`
`and the prior art; and (4) objective evidence of secondary considerations of nonobviousness. See
`
`Graham, 383 U.S. at 17-18; Miles Labs., Inc. v. Shandon Inc., 997 F.2d 870, 877, 27 U.S.P.Q.2d
`
`1123, 1128 (Fed. Cir. 1993).
`
`A statement that modifications of the prior art to meet the claimed invention would have been
`
`“well within the ordinary skill of the art at the time the claimed invention was made”because the
`
`references relied upon teach that all aspects of the claimed invention were individually known in the
`
`art, is not sufficient to establish a prima facie case of obviousness without some objective reason to
`
`combine the teachings of the references. M.P.E.P.
`
`§ 2143.01 (citing Ex parte Levengood,
`
`28 U.S.P.Q.2d 1300 (B.P.A.I. 1993)).
`
`“[R]ejections on obviousness cannot be sustained by mere
`
`Page 7 of 73
`
`-2-
`
`Page 7 of 73
`
`

`

`Control No. 95/001,789
`
`conclusory statements;
`
`instead,
`
`there must be some articulated reasoning with some rational
`
`underpinning to support the legal conclusion of obviousness.” KSR Int’] Co. v. Teleflex Inc., 550
`
`US. 398, 418, 82 U.S.P.Q.2d 1385, 1396 (2007) (quoting Jn re Kahn, 441 F.3d 977, 988, 78
`
`U.S.P.Q.2d 1329, 1336 (Fed. Cir. 2006)).
`
`Further, even in view of KSR,it is not permissible to simply “pick and choose” elements of
`
`the prior art to arrive at the claimed subject matter. There must be somebasis or rationale suggesting
`
`the modification and a reasonable expectation of success. M.P.E.P. § 2143.02
`
`3.
`
`The Law of Inherency
`
`The express, implicit, and inherent disclosures of a prior art reference may be relied upon in
`
`the rejection of claims under 35 U.S.C. § 102 or § 103. M.P.E.P. § 2112. The fact that a certain
`

`B.
`
`Backgroundof the ’211 Patent
`
`The ’211 patent discloses several embodiments of a domain nameservice (“DNS”) system
`
`for establishing a secure communication link,
`
`such as a virtual private network (“VPN”)
`
`communication link, between devices connected to a network.
`
`In one such embodiment, a novel,
`
`specialized DNS server receives a traditional DNS request, and the DNS server automatically
`
`facilitates the establishment of a secure communication link between a target node and a user.
`
`(Keromytis Decl. 416;
`
`’211 patent 39:30-35.) This specialized DNS server is different from a
`
`conventional DNS server known at
`
`the time of the invention for at
`
`least the reason that the
`
`specialized DNSserver supports the establishment of a secure communication link beyond merely a
`
`requested IP address or public key. (Keromytis Decl. 4 16.)
`
`For example, in the exemplars of FIGS. 26 and 27 of the ’211 patent, reproduced below, a
`
`DNSserver 2602 including a DNS proxy 2610 supports establishing a VPN link between a computer
`
`2601 and a secure target site 2604. (211 patent 39:47-41:43; Keromytis Decl. | 17.)

`
`FIG. 27
`
`In one embodiment, the DNS server 2602 receives a DNS request for a target site from computer
`
`2601. (211 patent 40:32-35; Keromytis Decl. 418.) The DNS proxy 2610 determines whether the
`
`target site is a secure site.
`
`(211 patent 39:57-59, 40:32-40; Keromytis Decl. 418.)
`
`If access to a
`
`secure site has been requested, the DNS proxy 2610 determines whether the computer 2601 is
`
`authorized to access the site.
`
`(211 patent 40:40-42; Keromytis Decl. 418.) If so, the DNS proxy
`
`2610 transmits a message to gatekeeper 2603 to facilitate the creation of a VPN link between
`
`computer 2601 and secure target site 2604.
`
`(211 patent 39:63-66.) The DNS proxy 2610 then
`
`responds to the computer’s 2601 DNS request with an address received from the gatekeeper 2604.
`
`(Id. at 40:3-7; Keromytis Decl. 4 18.) A secure VPN link is then established between the computer
`
`2601 and the secure target site 2604.
`
`(211 patent 40:55-58; Keromytis Decl. J 18.) As shown in
`
`this example, the specialized DNS server supports creating a secure communication link and does
`
`more than a conventional DNSserverat the time of the invention. (Keromytis Decl. 4 18.)
`
`The ’211 patent highlights this distinction between the specialized DNS server disclosed in
`
`its specification and a conventional DNS scheme, which merely returns a requested IP address or
`
`public key:
`
`Conventional Domain Name Servers (DNSs) provide a look-up function that
`retums the IP address of a requested computer or host. For example, when a
`computer user types in the web name “Yahoo.com,”the user’s web browser
`transmits a request to a DNS, which converts the name into a four-part IP
`addressthat is returned to the user's browser. ...

`

`Control No. 95/001,789
`
`One conventional scheme that provides secure virtual private networks over
`the Internet provides the DNS server with the public keys of the machines
`that the DNS server has the addresses for. This allows hosts to retrieve
`automatically the public keys of a host that the host is to communicate with
`so that the host can set up a VPN without having the user enter the public key
`of the destination host. One implementation of this standard is presently
`being developed as part of the FreeS/WAN project (RFC 2535).
`
`The conventional schemesuffers from certain drawbacks. For example, any
`user can perform a DNS request. Moreover, DNS requests resolve to the
`same valuefor all users.
`
`According to certain aspects of the invention, a specialized DNSservertraps
`DNSrequests and, if the request is from a special type of user (e.g., one for
`which secure communication services are defined), the server does not return
`the true IP address of the target node, but instead automatically sets up a
`virtual private network between the target node andthe user.
`
`(211 patent 38:58-39:35; Keromytis Decl. § 19.) Compared with a conventional DNS knownat the
`
`time of the filing date of the °211 patent, the specialized DNS disclosed in the ’211 patent supports
`
`establishing a secure communication link. (Keromytis Decl. 19.) The claims of the ’211 patent are
`
`also directed to a domain nameservice for establishing a secure communication link.
`
`(See, e.g., °211
`
`patent 55:38-46, 57:38-46, 59:9-60:8; Keromytis Decl. § 19.) Moreover, certain claims are directed
`
`to a domain nameservice system configured and arranged to indicate in response to a query for a
`
`network address whether
`
`the domain name service system supports establishing a secure
`
`communication link.
`
`(See, e.g., °211 patent 55:38-46; Keromytis Decl. § 19; see also ’211 patent
`
`57:38-46, 59:9-60:8.)
`
`Il.
`
`CLAIMS1-60 ARE PATENTABLE
`
`A.
`
`The Rejections Based on Solana and/or Reed Are Improper Because Neither
`Reference Has Been Shownto Be Prior Art (Grounds1-8, 11, 15, 19, 24, 28, and
`33)
`
`As a threshold matter, the Request and the Office Action rely on the following two references
`
`without showing that these references have been published:
`
`1. E. Solanaet al., “Flexible Internet Secure Transactions Based on Collaborative Domains,”
`
`Lecture Notes in Computer Science, vol. 1361, at 37-51 (“Solana”) (Req. Ex. X1); and
`2. M. Reed et al., “Proxies for Anonymous Routing,” 12 Annual Computer Security
`
`Applications Conference, San Diego, CA (“Reed”) (Req. Ex. X10).
`
`Neither reference is a patent.
`
`The only support for these references being prior art printed
`
`publicationsis a bald assertion in the Request, adopted by the Office Action, that the references were
`
`Page 10 of 73
`
`Page 10 of 73
`
`

`

`Control No. 95/001,789
`
`publicly distributed prior to the effective date of the °211 patent. This attorney argument does not
`
`establish these referencesasprior art for at least the following reasons.
`
`1.
`
`A Reference Is a “Printed Publication” Only When the Requisite
`Showing Is Made
`
`3°
`
`Solana and Reed are prior art only if they are “printed publications.”
`
`The statutory phrase
`
`“printed publication” means that the alleged reference must have been sufficiently accessible to the
`
`public interested in the art. Zn re Cronyn, 890 F.2d 1158, 1160 (Fed. Cir. 1989) (quoting Constantv.
`
`Advanced Micro-Devices, Inc., 848 F.2d 1560, 1568 (Fed. Cir. 1988)). M.P.E.P. § 2128 provides in
`
`part:
`
`A reference is a “printed publication” only “upon a satisfactory showing that
`such document has been disseminated or otherwise made available to the
`extent that persons interested and ordinarily skilled in the subject matter or
`art, exercising reasonable diligence, can locate it.” Jn re Wyer, 655 F.2d 221,
`210 USPQ 790 (C.C.P.A. 1981) (quoting LCE. Corp. v. Armco Steel Corp.,
`250 F. Supp. 738, 743, 148 USPQ 537, 540 (SDNY 1966)).
`
`Thus, a showing of dissemination and public accessibility are the keys to the legal
`
`determination of whether a document was “published.” The record is devoid of any showing that
`
`Solana and Reed were disseminated or otherwise publicly available at the time asserted by the
`
`Requester. Rather,
`
`the Request baldly asserts that “So/ana is a printed publication that was
`
`distributed to the public without restriction no later than 1997.” (Req. at 11.) Similarly, the Request
`
`asserts that “Reed is a printed publication that was distributed publicly without restriction no later
`
`than December 13, 1996... .” (ad. at 12.)
`
`Solana contains no publication date on the document. The face of the document identifies
`
`only that the authors are affiliated with the University of Geneva. There is no indication on the
`
`document that it was published on the date asserted by the Requester.
`
`Reedidentifies the 12th Annual Security Applications Conference, San Diego, CA, and a
`
`date of December 9-13, 1996, but there is no evidence that the document wasactually “published”
`
`within those dates, nor that the document was “otherwise available to the extent that persons
`
`interested and ordinarily skilled in the subject matter or art, exercising reasonable diligence, could
`
`locate it” at the time.

`
`2.
`
`Requester Failed to Satisfy Its Duty to Disclose Any Evidence of
`Publication and Is Presumed to Have None
`
`Under 37 C.F.R. § 11.18, the Requester was required to produce any evidence proving
`Solana or Reed were publicly distributed without restriction at the time asserted by the Requester.”
`
`Yet, it produced none. Thelogical conclusionis that no such evidence exists. Should the Requester
`
`subsequently attempt to introduce any evidence that Solana or Reedis prior art at the time asserted
`
`by the Requester, then the remedies provided by 37 C.F.R. § 11.18(c) should be exercised—absent a
`
`showing that the evidence wasnot available to the Requester at the time the Request was filed—to
`
`strike the paper attempting to submit that evidence, 37 C.F.R. § 11.18(c)(1), or to terminate this
`
`proceeding entirely, 37 C.F.R. § 11.18(c)(5)).
`
`3.
`
`Requester’s Bare Contention of Publication Is Inadequate
`
`Asstated above, the Requester’s sole basis for relying on Solana and Reed aspriorart is a
`
`bald assertion that they were printed publications distributed before the critical date. These bald
`
`assertions are nothing more than attorney argument, which is not evidence. See In re Wyer, 655 F.2d
`
`221, 227 (C.C.P.A. 1981) (‘[T]he one who wishes to characterize the information, in whatever form
`
`it may be, as a ‘printed publication’ .. . should produce sufficient proof of its dissemination orthat it
`
`has otherwise been available and accessible to persons concerned with the art to which the document
`
`relates and thus mostlikely to avail themselves of its contents ... .” (emphasis added)).
`
`The M.P.E.P. expressly recognizes that attorney argument
`
`is not evidence: M.P.E.P.
`
`§ 716.01(c) (“The arguments of counsel cannot take the place of evidencein the record.” (citing Jn re
`
`Schulze, 346 F.2d 600, 602, 145 U.S.P.Q. 716, 718 (C.C.P.A. 1965))). Although M.P.E.P.
`
`§
`
`716.01(c) focuses on certain types of evidence typically used to rebut rejections, it is not exclusive to
`
`those types of evidence. Moreover,
`
`the broader notion of M.P.E.P.
`
`§ 716.01(c) that attorney
`
`argument cannot replace real evidence is a well founded, common-sense position permeating the
`
`Office rules.
`
`Because the record is devoid of evidence that Solana and Reed were printed publications on
`
`the dates asserted, each rejection based, in whole or in part, on either reference is fatally defective.
`
`°37 C.E.R. § 11.18(b)(2)(iii) requires that all “factual contentions have evidentiary support
`or, if specifically so identified, are likely to have evidentiary support after a reasonable opportunity
`for further investigation or discovery ....° (emphasis added). The Requester’s factual contentions
`regarding the public distribution of Solana and Reed do not state that those contentionsare likely to
`have evidentiary support.

`
`

`

`Control No. 95/001,789
`
`Patent Ownerrespectfully requests that all such rejections (specifically Grounds 1-8, 11, 15, 19, 24,
`
`28, and 33) be withdrawn. Without admitting that Solana and Reed are publications as of the dates
`
`asserted by the Requester, Patent Owner will assume, arguendo, that the references are publications
`
`as of the asserted dates for the purposes of this response.
`
`B.
`
`The Rejections Based on the RFC Documents (Grounds2, 5-8, 10, 13-20, and 22-
`35) Are Improper Because the RFC Documents Have Not Been Shown to Be
`Prior Art
`
`Similarly, the Request and the Office Action rely on several RFC documents (collectively
`
`referred to in this section as “the RFC documents”) without showing that these references have been
`
`published:
`
`1. RFC 2230, “Key Exchange Delegation Record for the DNS” (“RFC 2230”) (Req.
`
`Ex. X4);
`
`2. RFC 2538, “Storing Certificates in the Domain Name System (DNS)” (“RFC
`
`2538”) (Req. Ex. X5);
`
`3. RFC 2401, “Security Architecture for the Internet Protocol” (“RFC 2401”) (Req.
`
`Ex. X6);
`
`4. RFC 2065, “Domain Name System Security Extensions” (“RFC 2065”) (Req. Ex.
`
`X7);
`
`5. RFC 920, “Domain Requirements” (“RFC 920”) (Req. Ex. X8);
`
`6. RFC 2504, “Users’ Security Handbook” (“RFC 2504”) (Req. Ex. X9);
`
`7. RFC 1035, “Domain Names—Implementation and Specification” (“RFC 1035”)
`
`(Req. Ex. Y2);
`
`8. RFC 1123, “Requirements for Internet Hosts—Applications and Support” (“RFC
`
`1123”) (Req. Ex. Y3);
`
`9. RFC 1825, “Security Architecture for the Internet Protocol” (“RFC 1825”) (Req.
`
`Ex. Y4);
`
`10. RFC 2459, “Internet X.509 Public Key Infrastructure Certificate and CRL
`
`Profile” (“RFC 2459”) (Req. Ex. Y5); and
`
`11. RFC 1034, “Domain Names—Concepts and Facilities” (“RFC 1034”) (Req. Ex.
`
`Y6).
`
`The RFC documents cited in the Request cannot be relied on as publications as of the asserted dates
`
`because the record is devoid of evidence that any of these references are patents or printed
`
`publications as of those dates.

`
`The Requester appears to have relied on the date (month and year, or year) indicated in each
`
`of the RFC documents. The Requester asserted, for example, that “RFC 2230 is a printed publication
`
`that was distributed to the public without restriction
