`
`
`
`MOTION FOR ISSUANCE OF LETTERS ROGATORY
`
`(UNOPPOSED BY SIX DEFENDANTS)
`
`Pursuant to Federal Rule of Civil Procedure 4(h)(2) and 4(f)(2)(B), Plaintiff Ocean
`
`Semiconductor LLC (“Ocean”) respectfully requests that this Court issue Letters Rogatory in the
`
`form attached hereto as Exhibit A to the addressed to the Appropriate Judicial Authority of
`
`Taiwan, compelling the production of documents and testimony from third party United
`
`Microelectronics Corporation (“UMC”). Ocean brings this motion in order to obtain relevant
`
`evidence not available to it by any other means.
`
`I.
`
`BACKGROUND
`
`Following the opening of discovery in the above-captioned cases on December 9, 2021,
`
`Ocean promptly served subpoenas containing identical requests for production and deposition
`
`topics (“Discovery Requests”) to both UMC and its U.S. subsidiary UMC Group (USA)
`
`(“UMC USA”). (Ex. B.)1 After receiving a requested extension to its deadline to respond to
`
`
`1 Exhibits B and E are the subpoenas served on UMC and Exhibits C and F are the responses
`served, respectively, by UMC USA and UMC in case No. 6:20-cv-1210-ADA. Identical
`subpoenas and responses were served in cases No. 6:20-cv-1211-ADA, No. 6:20-cv-1212-ADA,
`No. 6:20-cv-1213-ADA, No. 6:20-cv-1214-ADA, No. 6:20-cv-1215-ADA, and No. 6:20-cv-
`1216-ADA.
`
`
`
`1
`
`
`
`Case 6:20-cv-01214-ADA Document 54 Filed 02/16/22 Page 4 of 9
`
`Ocean’s Discovery Requests, UMC USA served responses and objections on January 14, 2022.
`
`(Ex. C.) UMC USA responded to each request for production that it either had no non-
`
`privileged, relevant, responsive documents or no documents that were not equally available
`
`from parties to the above-captioned cases. (Id. at 12-82.)
`
`After subpoenas were mailed to UMC via FedEx and Registered Mail, UMC’s counsel
`
`sent a letter to Ocean’s counsel on January 21, 2022 stating that UMC had no duty to respond
`
`to Ocean’s subpoenas but that UMC “would be willing to discuss producing documents
`
`responsive to certain document requests in the subpoenas if Ocean is willing to significantly
`
`narrow the scope of its requests.” (Ex. D.) After Ocean sent UMC’s counsel amended
`
`subpoenas with a significantly reduced number (from forty-five to twenty-two) of requests for
`
`production on January 27, 2022 (Ex. E), UMC served responses on Ocean on February 11,
`
`2022 stating that it considered the subpoenas improper and would produce neither documents
`
`nor a witness. (Ex. F.) Specifically, UMC identified Ocean’s “fail[ure] to request and obtain
`
`issuance of a letter rogatory to the Appropriate Judicial Authority of Taiwan requesting their
`
`assistance in serving and enforcing the Subpoena.” (Id. at 2.)
`
`As set forth in the Complaints filed in the above-captioned actions (see, e.g., Docket
`
`No. 1 in case No. 6:20-cv-1210-ADA at ¶¶ 8-19), Ocean has reason to believe that UMC is in
`
`possession of information that is relevant to Ocean’s claims of infringement under 35 U.S.C. §
`
`271(g). Accordingly, Ocean respectfully requests that the Court issue Letters Rogatory
`
`requesting that UMC be compelled to produce all documents that are responsive to Ocean’s
`
`requests for production, and a witness to testify on each of the deposition topics, as set forth in
`
`Exhibit A.

`
`II.
`
`ARGUMENT
`
`“Federal courts may issue letters rogatory to foreign tribunals, agencies, or officers in
`
`order to seek ‘assistance in the production of evidence located in the foreign country.”
`
`Blitzsafe Tex. v. Jaguar Land Rover, CIVIL ACTION NO. 2:17-CV-00424-JRG, 2019 U.S.
`
`Dist. LEXIS 240026, at *2 (quoting United States v. El-Mezain, 664 F.3d 467, 516-17 (5th
`
`Cir. 2011), as revised (Dec. 27, 2011)). Federal courts have “inherent power” to issue letters
`
`rogatory. Nat. Gas Pipeline Co. of Am. v. Energy Gathering, Inc., 2 F.3d 1397, 1408 (5th Cir.
`
`1993); accord 28 U.S.C. § 1781. In the Fifth Circuit, “[t]he decision to issue a letter rogatory
`
`is . . . entrusted to the sound discretion of the district court . . . .” El-Mezain, 664 F.3d at 517.
`
`Further, there “must be a ‘good reason’ to deny a request for letters rogatory, at least when the
`
`request is made pursuant to Fed. R. Civ. P. 28(b).” Triump Aerostructures v. Comau, Inc., No.
`
`3:14-cv-2329-L, 2015 U.S. Dist. LEXIS 125347, at *8 (N.D. Tex. Sep. 18, 2015) (internal
`
`citations omitted); see also id. at *9 (stating that letters rogatory or letters of request should be
`
`consistent with Rule 26(b)(1)).
`
`Ocean’s Discovery Requests are within the scope of discovery as defined by Rule 26.
`
`Specifically, they narrowly seek information relating to UMC’s use of certain manufacturing
`
`tools, systems, platforms, software and equipment used to manufacture or fabricate integrated
`
`circuits (including all of the infringing products) on behalf of MediaTek Inc., MediaTek USA
`
`Inc., NVIDIA Corporation, NXP USA, Inc., Renesas Electronics Corporation, Renesas
`
`Electronics America, Inc., STMicroelectronics, Inc., Silicon Laboratories Inc. and Western
`
`Digital Technologies, Inc.—all of whom are defendants in the above-captioned actions before
`
`this Court ("Defendants").
`
`The requests and topics also seek information related to UMC’s business relationships
`
`
`
`3
`
`
`
`Case 6:20-cv-01214-ADA Document 54 Filed 02/16/22 Page 6 of 9
`
`with Defendants and the manufacturers of the infringing tools, sale of infringing
`
`instrumentalities, and importation of infringing instrumentalities into the United States. All of
`
`this information is directly relevant to Ocean’s claim of infringement under 35 U.S.C. §
`
`271(g).
`
`The requests for production also seek information related to Defendants’ control over
`
`UMC with respect to its manufacture of integrated circuits, including all infringing products,
`
`for Defendants, knowledge of the patents at issue in these cases, agreement to be indemnified
`
`or to indemnify Defendants or manufacturers of infringing, tools, systems, platforms, software
`
`and equipment with respect to infringement of the patents at issue in these cases, and
`
`information on production costs and sales volume of infringing integrated circuits. All of
`
`these topics are relevant to Ocean’s claims of indirect infringement and to the calculation of
`
`reasonable damages.
`
`There are no alternative means of obtaining the requested information from UMC as
`
`UMC USA has responded either that “it has no relevant, non-privileged responsive
`
`documents” (e.g., Ex. C at 23) or that “it has no non-privileged, relevant, responsive
`
`documents that would not also be available from one or more parties to the underlying action.”
`
`e.g., id. at 29). Based on UMC USA’s stated inability to produce any of the categories of
`
`documents sought and refusal to produce others, as well as UMC’s repeated refusals to
`
`produce any documents (Exs. D, F), even when presented with a narrowed version of the
`
`original subpoena, there are no alternative means of obtaining the discovery it seeks. This is
`
`particularly true where no Defendant has acknowledged that it possesses information relating
`
`to UMC’s use of certain manufacturing tools, systems, platforms, software and equipment for
`
`manufacturing or fabricating any of Defendants’ infringing products. (See, e.g. Ex. G,
`
`
`
`4
`
`
`
`Case 6:20-cv-01214-ADA Document 54 Filed 02/16/22 Page 7 of 9
`
`Defendant MediaTek’s Responses to Plaintiff’s First Set of Requests for Production of
`
`Documents at 13: “MediaTek is unable to identify products pursuant to Request for Production
`
`No. 1 because it does not manufacture, fabricate, or assemble any product itself, nor does it
`
`have knowledge as to what equipment is involved in the manufacturing, fabrication, or
`
`assembly of its products.”)
`
`The requests for production and deposition topics in Attachment A are substantially the
`
`same as those in the amended subpoena that Ocean previously conveyed to UMC and
`
`represent a good-faith attempt to reduce any burden that responding might place on UMC.
`
`The definitions have been further narrowed. Moreover, UMC has specifically indicated that
`
`this information should be sought via Letters Rogatory. (Ex. F at 2.)
`
`Ocean respectfully requests that the Court return: (a) the original copy of the signed and
`
`issued Letters Rogatory; and (b) one certified copy, to the undersigned counsel. Ocean will
`
`transmit the issued Letters Rogatory to the United States Department of State to oversee
`
`transmission of the Letters Rogatory to Taiwan through diplomatic channels as provided in 28
`
`U.S.C. § 1781(a)(2).
`
`III. CONCLUSION
`
`The Court should issue an order issuing Letters Rogatory directed to the Appropriate
`
`Judicial Authority of Taiwan. The information sought through this Motion and Letters
`
`Rogatory is within the scope of discovery and necessary for Ocean to prosecute its claims in
`
`the above-captioned actions.
