Patent 7,188,180 B2

I. BACKGROUND
Microsoft Corporation (“Petitioner”) filed a Petition (“Pet.”)
1

requesting inter partes review of claims 1, 4, 6, 10, 12-15, 17, 20, 22, 26,
28-31, 35, and 37 of U.S. Patent No. 7,188,180 B2 (“the ’180 Patent,”
Ex. 1001) pursuant to 35 U.S.C. § 311-319. VirnetX Inc. (“Patent Owner”)
filed a Preliminary Response (“Prelim. Resp.”) on May 19, 2014. Paper 8.
We have jurisdiction under 35 U.S.C. § 314. The standard for
instituting inter partes review is set forth in 35 U.S.C. § 314(a):
THRESHOLD.— The Director may not authorize an inter
partes review to be instituted unless the Director determines
that the information presented in the petition filed under section
311 and any response filed under section 313 shows that there
is a reasonable likelihood that the petitioner would prevail with
respect to at least 1 of the claims challenged in the petition.
For the reasons described below, we determine that the Petition was
not filed timely within the statutory period of 35 U.S.C. § 315(b). We, thus,
deny inter partes review.
A. Related Proceedings
The ’180 Patent was asserted in a complaint for VirnetX Inc. v.
Microsoft Corp., Case No. 6:07-cv-00080 (E.D. Tex. filed April 5, 2007)
(Ex. 2001, “the 2007 complaint”), and a complaint for VirnetX Inc. v.
Microsoft Corp., Case No. 6:10-cv-00094 (E.D. Tex. filed March 17, 2010)
(Ex. 2004, “the 2010 complaint”). Prelim. Resp. 3.
The ’180 Patent also is involved in the following proceedings:
VirnetX Inc. v. Microsoft Corp., Docket No. 6:13-cv-00351 (E.D. Tex.) (“the
2013 complaint”); VirnetX Inc. v. Cisco Systems, Inc., Docket No. 6:10-cv-

IPR2014-00405 (filed concurrently). Pet. 1-2.

II. ANALYSIS
Petitioner was served with a complaint alleging infringement of the
’180 patent on three occasions. The first complaint (i.e., the 2007
complaint) was served on April 5, 2007, and the second complaint (i.e., the
2010 complaint) was served on March 17, 2010. The 2007 complaint and
the 2010 complaint were both served more than one year prior to the date on
which the Petitioner filed the present Petition requesting inter partes review
(February 4, 2014). The third complaint (i.e., the 2013 complaint) was
served less than one year prior to the date on which the Petitioner filed the
present Petition requesting inter partes review.
35 U.S.C. § 315(b) states:
An inter partes review may not be instituted if the petition
requesting the proceeding is filed more than 1 year after the
date on which the petitioner, real party in interest, or privy of
the petitioner is served with a complaint alleging infringement
of the patent.

As described above, 35 U.S.C. § 315(b) states that an inter partes
review may not be instituted if the petition is filed more than one year after
the date of service on Petitioner of a complaint alleging infringement of the
patent. In the present case, the Petition is filed more than one year after the
service date of a complaint alleging infringement of the ’180 patent. In fact,
IPR2014-00401
Patent 7,188,180 B2

the Petition is filed more than one year after the service date of two such
complaints, namely, the 2007 complaint and the 2010 complaint. Therefore,
pursuant to 35 U.S.C. § 315(b), inter partes review may not be instituted in
the present case.
Petitioner contends that 35 U.S.C. § 315(b) explicitly states that inter
partes review may not be instituted if the petition is filed more than one year
after the date a petitioner is served with “a” complaint alleging infringement
of the patent and that a third complaint was served less than one year prior to
the date of filing of the present Petition. Pet. 3. Petitioner also asserts that
35 U.S.C. § 315(b) is ambiguous, does not require explicitly that the
complaint be the “first” complaint, and that, in view of Petitioner’s
perceived ambiguities, “a complaint,” as specified in the statute, should be
interpreted as “a latest complaint,” and should not be interpreted as “a first
complaint.” Pet. 8-9. While Petitioner asserts that 35 U.S.C. § 315(b) does
not require that the complaint be the “first” complaint served, we note,
rather, 35 U.S.C. § 315(b) merely requires “a” complaint.
We decline Petitioner’s invitation to amend the statute by inserting
either “latest” or “first” (or “third,” in this case) into the statute. Rather, we
interpret “a complaint,” in accordance with the plain language of 35 U.S.C.
§ 315(b), to include “a complaint” as explicitly stated. The statute prohibits
institution of inter partes review if the petition is filed more than one year
after the date petitioner is served with “a” complaint. The record shows that
in this case, Petitioner was served with “a” complaint on April 5, 2007 (the
2007 complaint) and the Petitioner filed the present Petition for inter partes
review on February 4, 2014. Paper 2. The date a complaint was served
(April 5, 2007) predates the date Petitioner filed the Petition (February 4,
IPR2014-00401
Patent 7,188,180 B2

5

2014) by more than one year. Under these circumstances, pursuant to the
express language of 35 U.S.C. § 315(b), an inter partes review may not be
instituted.
We note that in the dismissal of the 2010 complaint, the Court ordered
“that all of the claims asserted against [Petitioner] in this action are
dismissed with prejudice.” Ex. 1013. Petitioner asserts that “[Patent
Owner] voluntarily dismissed its infringement actions, pursuant to Fed. R.
Civ. P. 41, before entry of a final judgment” and that “voluntary dismissal of
an infringement action with prejudice . . . has been found to nullify the legal
effect of service of a corresponding complaint.” Pet. 4-5 (citing Universal
Remote Control, Inc. v. Universal Electronics, Inc., Case IPR2013-00168,
slip op. at 6 (PTAB Aug. 23, 2013) (Paper 9)). Similar to the 2010
complaint, in Universal Remote Control, Case IPR2013-00168, a complaint
alleging infringement of the patent was dismissed with prejudice. Although,
according to Universal Remote Control, “the Federal Circuit consistently has
interpreted the effect of [dismissals without prejudice] as leaving the parties
as though the action had never been brought,” the petitioner in that case
failed to show that the dismissal with prejudice should be treated the same as
a dismissal without prejudice and, thus, the petition was held to have been
not filed timely within the statutory period of 35 U.S.C. § 315(b). Universal
Remote Control, Inc. v. Universal Electronics, Inc., Case IPR2013-00168,
slip op. at 6 (PTAB Aug. 23, 2013) (Paper 9). Here, Petitioner also has not
shown that voluntary dismissal of an infringement action with prejudice
should nullify the legal effect of service of the earlier complaints (i.e., that a
dismissal with prejudice should be treated the same as a dismissal without
prejudice).

Petitioner maintains that invalidity counterclaims or affirmative
defenses by Petitioner corresponding to the 2007 complaint and the 2010
complaint were dismissed without prejudice. Pet. 5-6. However, as
previously described, in the dismissal of the 2010 complaint, the court
ordered “that all of the claims asserted against [Petitioner] in this action are
dismissed with prejudice.” Ex. 1013. Hence, the 2010 complaint, at least,
was dismissed with prejudice and, therefore, the parties are not left as
though the action had never been brought.
Also, as Patent Owner points out, in the dismissal of the 2007
complaint, the court ordered “that all claims asserted against [Petitioner] in
this action are dismissed with prejudice” and the “dismissal is with prejudice
to [Petitioner]’s ability to assert any other counterclaims asserted by
[Petitioner] in this action.” Ex. 1012.
According to the record, Petitioner and Patent Owner entered into a
Settlement and License Agreement (“settlement agreement”). Ex. 1015.
Petitioner contends that the settlement agreement states that a subset of
“‘affirmative defenses and counterclaims of (i) non-infringement and
invalidity shall be dismissed without prejudice.’” Pet. 5 (quoting Ex. 1015
§ 5.1). Petitioner, thus, argues that the infringement action corresponding to
the 2007 complaint should be treated as dismissed without prejudice (and,
therefore, the dismissal should nullify the legal effect of service of the 2007
complaint). We disagree. Pursuant to 35 U.S.C. § 315(b), what matters is
the temporal relationship between the filing date of the petition requesting
inter partes review and the date the petitioner is served with a complaint
alleging infringement of the patent. While 35 U.S.C. § 315(b) explicitly
states the relevance of the service date of a complaint alleging infringement
IPR2014-00401
Patent 7,188,180 B2

of the patent, Petitioner does not show persuasively that the date of any of
Petitioner’s affirmative defenses and counterclaims also pertain to the
statute.
Petitioner argues that “the ‘without prejudice’ manner in which
[Petitioner]’s affirmative defenses and counterclaims were dismissed placed
[Petitioner] and [Patent Owner] in the same position as to invalidity that they
would have been had the earlier invalidity action never been brought.” Pet.
6-7. However, Petitioner does not show sufficiently that the “with
prejudice” manner in which all claims asserted against Petitioner were
dismissed (see, e.g., Ex. 1012) also places both Petitioner and Patent Owner
in the same position as to “a complaint alleging infringement of the patent”
(as per 35 U.S.C. § 315(b)). Rather, based on the “with prejudice” manner
of the dismissal, it appears that the parties are not in the same position as if
the action had never been brought.
We are, therefore, not persuaded that the Petition was filed timely in
accordance with 35 U.S.C. § 315(b).

III. CONCLUSION
We are not persuaded that the Petition was filed timely, within the
statutory period of 35 U.S.C. § 315(b). We, thus, deny inter partes review
of U.S. Patent No. 7,188,180 B2.

IV. ORDER
For the reasons given, it is
ORDERED that the Petition is denied as to all challenged claims and
no trial is instituted.
