`
`Third Party Request for Ex Parte Reexamination of Patent No. 10,218,606
`
`Dear Commissioner:
`
`Twitter, Inc. (hereinafter "Twitter" or "Requester") respectfully requests ex parte
`
`reexamination pursuant to 35 U.S.C. § 302 and 37 C.F.R. § 1.510 of claims 1, 3-9, 11, 13-16, 18-
`
`24, 26, 27, 29, 30, 32, 35-37, 41, 42, 44 of U.S. Patent No. 10,218,606 to Clay Perreault et al.
`
`("the '606 patent" or Exhibit 1001). The '606 patent is titled, "Producing Routing Messages for
`
`Voice Over IP Communications," and was filed on March 30, 2018. The chain of applications
`
`that led to the '606 patent began with a provisional application filed on November 2, 2006,
`
`which is the earliest possible effective filing date for the '606 patent. The '606 patent is thus
`
`governed by pre-America Invents Act ("AIA") 35 U.S.C. §§ 102 and 103. See Manual of Patent
`
`Examining Procedure ("MPEP") § 2159 (9th ed., rev. June 2020).
`
`The '606 patent is assigned to VoIP-Pal.com, Inc. ("VoIP-Pal") according to United
`
`States Patent and Trademark Office ("USPTO") records at the time of this request.
`
`Pursuant to 37 C.F.R. § 1.510, this request for reexamination includes:
`
`•
`
`a statement pointing out each substantial new question of patentability based on prior
`
`art patents and printed publications;
`
`•
`
`•
`
`an identification of every claim for which reexamination is requested;
`
`a detailed explanation of the pertinence and manner of applying the cited prior art to
`
`every claim for which reexamination is requested;
`
`•
`
`a copy of each of the cited prior art patents and printed publications, attached as
`
`Exhibits 1002, 1003, 1004, and 1005;
`
`•
`
`a certification that a copy of the request filed has been served in its entirety on the
`
`patent owner at the address as provided for in 37 C.F.R. § l.33(c);
`
`•
`
`a certification that the statutory estoppel provisions of 35 U.S.C. §§ 315(e)(l) or
`
`325(e)(l) do not prohibit the Requester from filing this request; and
`
`•
`
`the appropriate fee under 37 C.F.R. § l.20(c)(l).
