`
`
`PATENT L.R. 3-1(A) & (B) DISCLOSURE OF ASSERTED CLAIMS &

`
`Based on the information Twilio currently possesses, Twilio contends that Defendant
`
`TeleSign Corporation (“TeleSign”) infringes Claims 1–4, 6–7, and 10–12 of the ’021 Patent,
`
`Claims 1–6, 9, 10, 13, and 22 of the ’465 Patent, Claims 1–5, 13–14, 16–17, and 19–23 of the

`
`Patent, Claims 1, 3–5, and 8–9 of the ’833 Patent, and Claims 1–12 and 15–19 of the ’217 Patent
`
`(“the Asserted Claims”) under Title 35, Section 271(a) of the United States Code by making,
`
`using, importing, selling, offering for sale, or otherwise disposing of the Accused Products. The
`
`Accused Products are TeleSign’s Smart Verify, Auto Verify, SMS Verify, Voice Verify, Push

`
`Appendices A–G identify where each element of each Asserted Claim is found in the
`
`Accused Products. Appendix A is a chart setting forth Twilio’s infringement theories for the
`
`’021 Patent which apply to TeleSign’s SMS Verify and Voice Verify products. Appendix B is a
`
`chart setting forth Twilio’s infringement theories for the ’465 Patent which apply to TeleSign’s
`
`Voice Verify product. Appendix C is a chart setting forth Twilio’s infringement theories for the
`
`’376 Patent which apply to TeleSign’s Smart Verify, Auto Verify, SMS Verify, Voice Verify,
`
`and Push Verify products. Appendix D is a chart setting forth Twilio’s infringement theories for
`
`the ’051 Patent which apply to TeleSign’s Smart Verify, Auto Verify, SMS Verify, Voice
`
`Verify, and Push Verify products. Appendix E is a chart setting forth Twilio’s infringement
`
`theories for the ’962 Patent which apply to TeleSign’s Score product. Appendix F is a chart
`
`setting forth Twilio’s infringement theories for the ’833 Patent which apply to TeleSign’s Score
`
`product. Appendix G is a chart setting forth Twilio’s infringement theories for the ’217 Patent
`
`which apply to TeleSign’s Smart Verify, Auto Verify, SMS Verify, Voice Verify, and Push
`
`Verify products. Because claim construction is yet to be determined in this case and because
`
`Twilio’s investigation is ongoing, Twilio reserves the right to supplement this disclosure.

`III. PATENT L.R. 3-1 (E) LITERAL INFRINGEMENT AND INFRINGEMENT
`UNDER DOCTRINE OF EQUIVALENTS
`
`Based on the information Twilio currently possesses, Twilio contends that each Accused
`
`Product literally infringes the Asserted Claims and also infringes the Asserted Claims under the
`
`doctrine of equivalents, as explained in Appendices A–G.
`
`IV. PATENT L.R. 3-1 (F) PRIORITY CLAIMS
`
`Twilio hereby identifies in the following chart (1) Asserted Patents that claim priority to
`
`an earlier application; and (2) the priority date to which each Asserted Claim is entitled based
`
`only upon priority to the earlier application. Twilio reserves the right to claim actual priority to
`
`different dates based on, for example, conception and diligence.

`

`VI. PATENT L.R. 3-1 (H) TIMING OF FIRST INFRINGEMENT, DAMAGES
`PERIOD
`
`TeleSign has been infringing each of the Asserted Patents at least since the date that each
`
`patent was issued, as shown in the table below:
`
`
`
`Asserted Patents
`
`Issue Date
`
`’021 Patent
`
`November 6, 2012
`
`’962 Patent

`

`
`June 17, 2014
`
`September 16, 2014
`
`December 29, 2015
`
`Feb. 23, 2016
`
`The damages period for each Asserted Patent begins at least as early as the date listed above.
`
`Twilio also seeks an injunction to prevent TeleSign’s continued infringement. If an injunction is
`
`not granted, the damages period will continue until the expiration of each Asserted Patent.
`
`
`
`VII. PATENT L.R. 3-1 (I) WILLFUL INFRINGEMENT
`
`Based on the information Twilio currently possesses, Twilio contends that TeleSign has
`
`continued its infringing activities after receiving notice of the Asserted Patents and, therefore,
`
`such infringement is willful, entitling Twilio to the recovery of increased damages under 35
`
`U.S.C. § 284. TeleSign became aware of the Asserted Patents and Twilio’s products during its
`
`diligence in filing suit against Twilio. Furthermore, TeleSign’s engineers had access to Twilio
`
`when TeleSign was a customer of Twilio. During that time, TeleSign’s engineers were able to
`
`study Twilio’s source code and the design of Twilio’s products. For example, TeleSign’s co-
`
`founder and Vice President of Product Strategy, Stacy Stubblefield, had a private Twilio account
`
`that was created in September of 2009. Through this account, Ms. Stubblefield gained access to
`
`Twilio’s products. Ms. Stubblefield used the information that she learned from her Twilio
