`RE: Regeneron v. Samsung, 23-cv-94 & 23-cv-106 (NDWVa)
`
`Counsel, 
`
`  
`Regeneron has not provided any basis for its request in the procedures set forth in the Protective Order.  The Protective 
`Order provides that depositions containing confidential information may be designated as such, and there is no 
`mechanism requiring a line‐by‐line redaction. 
`
`  
`This position is not inconsistent with our redactions to our PI papers.  The cited testimony of Dr. Boyle was made in the 
`context of his non‐infringement opinion involving SB’s confidential information.  Indeed, Dr. Boyle’s transcript was 
`withheld in its entirety from Amgen due to its highly confidential nature. 
`
`  
`We further note that Regeneron has not applied this rigorous review process to its own deponents, which underscores 
`the inconsistency and inequity of its demands. SB will adhere to the established procedures set forth in the Protective 
`Order. 
`
`  
`Regards, 
`Elliot

`Counsel,  
`  
`It has now been over two months since Regeneron made the below request for redacted copies of Dr. Boyle’s deposition 
`transcript.  SB has failed to comply.  SB previously contended that it is not required to perform a “line‐by‐line review of 
`each deposition.”  But no such review is necessary because Regeneron has provided SB with a short list of lines from the 
`specific transcript that it contends does not contain confidential information.  Additionally, Regeneron has now further 
`limited its request to only the documents pertaining to Dr. Boyle (and excluded the transcript of Dr. 
`Prentice).  Regeneron’s request is therefore narrow and would not be onerous for SB.  Indeed, SB has now provided 
`redactions to a number of documents pursuant to the parties’ stipulation regarding redactions, and yet, has failed to 
`respond to Regeneron’s request. 
`
`  
`By close of business 6/20, confirm whether SB agrees with Regeneron regarding the non‐confidential nature of the 
`below information and, if not, identify which lines SB considers confidential or OCEO and provide an explanation 
`supporting its designations.

`
`Counsel: 
`
`  
`As stated in our prior correspondence, SB has and will continue to abide the procedures set forth in the Protective Order 
`regarding the treatment of deposition transcripts containing confidential information.  As set forth in Paragraph 16 of 
`the Protective Order, SB has ten days following receipt of the final transcript to designate the deposition as 
`confidential.  Despite the fact this ten‐day period is only now expiring, SB has previously informed Regeneron that Dr. 
`Boyle’s transcript contains SB confidential information, a fact that Regeneron implicitly acknowledges given its repeated 
`requests for redactions.  SB therefore maintains its claim of confidentiality with respect to Dr. Boyle’s 
`transcript.  Moreover, we understand that Celltrion has asked that the Prentice deposition be designated 
`confidential.  Finally, there is nothing in the Protective Order that requires the parties to undertake the time consuming 
`and expensive process of conducting and line‐by‐line review of each deposition transcript to determine which pages and 
`lines of the transcript contain confidential information and Regeneron’s unilateral demands that SB does so are not 
`appropriate, particular under the expedited timelines that Regeneron has imposed.  We further note that Regeneron 
`has not undertaken this process for any of its deponents.  Regeneron has not provided any basis deviating from the 
`procedures set forth in the Protective Order and without more, SB intends to follow the procedures set forth in the 
`Protective Order.

`You have yet again failed to comply with Regeneron’s request.  Though we are not obligated to do so, we have provided 
`below a table of citations to information that Regeneron contends does not contain any OCEO information or Bioepis

`
`Counsel: 

`As we stated, Regeneron’s questioning and Dr. Boyle’s answers implicated Samsung Confidential information, including 
`Samsung’s Confidential BLA testing, throughout the transcript—indeed, analysis of those tests was the subject of Dr. 
`Boyle’s declaration.  Accordingly, pursuant to the Protective Order, we have designated the transcript as 
`Confidential.  We also note that this is consistent with the parties’ practice in other depositions. Pursuant to Paragraph 
`16, we are reviewing our designation with our client, but unless we change it within the time allotted by the PO, the 
`transcript remains Confidential and must be treated as such.  We are not required under the Protective Order to review 
`and designate each line of the transcript as confidential or non‐confidential.  Regeneron has not done as much in this 
`case and has not cited any authority or agreement for the proposition it can unilaterally impose such a requirement on 
`SB.  Regeneron’s statement that SB is somehow shielding the Court from the transcript is nonsensical—the transcript 
`can, of course, be submitted to the Court under seal here, in the same way Regeneron has submitted voluminous 
`amounts of its own Confidential information already.

`
`
`Samsung counsel, 

`Regeneron requested that you (1) identify any lines of testimony in the redacted version of pages 1‐288 of the transcript 
`(with lines 152:11‐16 redacted, as discussed below) that you believe contains Samsung’s confidential information; and 
`(2) provide a time today to confer.  Your response does neither.  Please comply with these requests immediately so that 
`Regeneron may understand and confer with you about your confidentiality designations. 

`The protective order does not restrict the use of nonconfidential information.  Your attempt to delay the resolution of 
`Regeneron’s challenge to Samsung’s improper confidentiality designation is prejudicial to Regeneron and improperly 
`seeks to shield nonconfidential information from the Court.

`We disagree with your characterization of the record and your unilateral attempt to de‐designate portions of the 
`transcript that contain SB’s confidential information.  As stated on the face of the transcripts themselves, SB’s counsel 
`designated the transcript Confidential on the record, pursuant to the Protective Order as well as the parties’ practice in 
`this case.  While we are still reviewing the transcript, aside from the testimony you cite below, Regeneron’s questioning 
`touched upon SB’s and REGN’s confidential information throughout (for instance, information reflective of SB’s BLA 
`testing), and SB’s designation of the transcript as confidential reflects that fact.  Pursuant to the Protective Order, the 
`transcript as a whole was designated Confidential. 

`Your position regarding SB’s designation of the transcript as Confidential and your demand for an immediate response is 
`inconsistent with both the parties’ practice in this case and, more importantly, the Protective Order’s requirement for 
`treatment of deposition transcripts, including as set out in Paragraph 16.  As we noted at the deposition, Regeneron 
`should familiarize itself with the Protective Order before making demands that directly contradict the parties’ agreed on 
`processes for designating and handling Confidential information in this case.

`
`
`
`
`Samsung counsel,
`
`
`
`
`
`At Thursday’s deposition of Dr. Boyle in the Regeneron v. Samsung case, Regeneron’s counsel indicated that
`the deposition would start with a portion that would not include any Samsung confidential
`information. Regeneron’s counsel asked Samsung’s counsel to note on the record if any particular testimony
`involved Samsung confidential information. During this first portion of the deposition, Samsung’s counsel
`identified only the testimony at 152:11-16 of the final transcript as allegedly involving Samsung confidential
`information.
`
`
`
`
`
`Aside from the testimony at 152:11-16, the first portion of the transcript of Dr. Boyle’s deposition (i.e., final
`transcript pages 1-288) contains no Samsung confidential information. Regeneron has prepared a version of
`this first portion of the transcript with the testimony at 152:11-16 redacted, and Regeneron understands that
`redacted transcript to contain no Samsung confidential information or Samsung outside counsel eyes only
`information. If you disagree, let us know no later than close of business on Monday what additional lines from
`pages 1-288 you contend contain Samsung confidential information and what times on Tuesday you are
`available to confer.
`
`
`
`Any delay in confirming that this redacted version of pages 1-288 of the transcript is nonconfidential will be
`understood as an effort to shield improperly the Court and Regeneron’s in-house counsel from information that
`is plainly nonconfidential.
