`
`
`
`
`
`DEFENDANTS’ OPPOSED REQUEST FOR DEPOSITION OF SEAGEN MOTION
`DECLARANT MS. CARRIE DISTLER AND FOR EXPEDITED BRIEFING
`
`Plaintiff Seagen Inc. (“Seagen”) filed a Motion for Judgment for Supplemental Damages
`
`and Ongoing Royalties (“Motion for Judgment”) and submitted a declaration in support of its
`
`Motion for Judgment from an economist Ms. Carrie Distler. (See Dkt. No. 443.) Therein, Ms.
`
`Distler writes that, if Seagen is entitled to an ongoing royalty, in her opinion a post-verdict
`
`hypothetical negotiation between the parties would lead to an outcome of a royalty of 10% to
`
`12% of non-party Daiichi Sankyo, Inc.’s net sales of Enhertu®. (Id.) Defendants Daiichi Sankyo
`
`Company, Limited, AstraZeneca Pharmaceuticals LP, and AstraZeneca UK Ltd.’s (collectively,
`
`“Defendants”) dispute both Ms. Distler’s opinion as well as many other opinions and assertions
`
`that she makes in her declaration. To test the veracity of Ms. Distler’s opinions and factual
`
`conclusions, as well as to better understand the content of her declaration and opinions,
`
`Defendants requested that Ms. Distler be made available for deposition on a mutually-agreed
`
`date, for a maximum of 3.5 hours, prior to September 15 (seven days before the joint proposed
`
`
`
`Case 2:20-cv-00337-JRG Document 455 Filed 08/30/22 Page 2 of 5 PageID #: 19611
`
`deadline for Defendants’ response to Seagen’s Motion for Judgment (see Dkt. No. 453)). Seagen
`
`refused, stating without any explanation that Seagen would only produce Ms. Distler for a mere
`
`1.5 hours of deposition. That is an insufficient amount of time to explore her 15-page
`
`declaration full of financial and economic exposition—as well as HER2-positive cancer
`
`treatment market analysis—and her reliance on 31 different exhibits (12 of which contain
`
`financial and market data upon which she relies). Seagen’s position is particularly prejudicial
`
`here, where it seeks up to a 50% increase of the royalty rate it asserts was implicitly found by the
`
`jury. (See Dkt. No. 443.)
`
`In light of the foregoing, Defendants respectfully request that the Court order Seagen to
`
`make its motion declarant, Ms. Distler, available for deposition on a mutually-agreed date, not
`
`exceeding 3.5 hours of time on the record, prior to September 15, 2022. Defendants note that
`
`Seagen has not represented that Ms. Distler is not available during this period, and, to the extent
`
`that she is only available at a later date, Defendants are willing to accommodate her schedule and
`
`adjust the briefing deadlines concerning Seagen’s Motion for Judgment.
`
`Defendants also request expedited briefing on its Opposed Request for Deposition of
`
`Seagen Motion Declarant Ms. Carrie Distler (“Opposed Request for Deposition”). There is good
`
`cause for an expedited resolution of this motion in light of the quickly approaching proposed
`
`deadline for Defendants’ response to Seagen’s Motion for Judgment. (See Dkt. No. 453.)
`
`Defendants therefore respectfully request that the Court order Seagen to respond to Defendants’
`
`Opposed Request for Deposition within three days.

`CERTIFICATE OF CONFERENCE
`
`On August 26, 2022, pursuant to Local Rule CV-7(h), counsel for Defendants met and
`
`conferred with counsel for Seagen. On August 29, 2022, counsel for Daiichi Sankyo Company,
`
`Limited repeated its request for Ms. Distler’s deposition to Seagen and agreed to limit it to a
`
`maximum of 3.5 hours on the record. On August 30, 2022, counsel for Seagen indicated that it
`
`opposed the requested deposition, and therefore opposes the relief sought by this motion.
