`
`Dear Wayne,
`
`In accordance with Patent Local Rule 4-2, TeleSign proposes the following
`preliminary constructions of the claim terms/phrases of U.S. Patent Nos.
`8,306,021; 8,837,465 and 8,755,376 (“asserted patents”) that were exchanged on
`May 15, 2017, attached as Exhibit A.
`
`Pursuant to Patent Local Rule 4-2(b), TeleSign may offer opinions from Dr. Seth
`Nielson in connection with the interpretation of claim terms. Dr. Nielson’s
`curriculum vita is attached as Exhibit B. Dr. Nielson may provide his testimony
`in the form of one or more declarations submitted with TeleSign’s claim
`construction briefing. Dr. Nielson, for example, is expected to provide opinions
`regarding:
`
`1.
`
`2.
`
`the construction of the disputed claim terms;
`
`his qualifications as an expert;
`
`the definition and qualifications of one of ordinary skill in the art in the
`2.
`context of the asserted patents;
`
`an overview of the technology in the asserted patents (including the
`3.
`background and context of the technology) at the time the patents were filed;
`
`regarding the terms “REST API” / “representational state transfer (REST)
`4.
`API” / “REST API request”: (a) a person of ordinary skill would be uncertain as to
`the meaning or scope of this term; and (b) the patent specification does not
`reasonably convey to a person of ordinary skill that the inventors had possession
`of the claimed subject matter, including the foregoing terms, as of the filing date
`of the patent;

`

`
`
`
`
`
`
`
`
`
`
`regarding the term “substantially REST API,” a person of ordinary skill
`5.
`would be uncertain as to the meaning or scope of this term; and
`
`rebuttal opinions to constructions and opinions offered by Twilio or its
`6.
`experts.
`
`TeleSign reserves the right to supplement these preliminary constructions
`based on: Twilio’s proposed constructions; the meet and confer session
`required under Patent Local Rule 4-2(c); and the Local Rules.
