ORDER GRANTING DEFENDANTS' MOTION FOR ISSUANCE OF LETTERS ROGATORY

[Re: ECF No. 106]

LAUREL BEELER, Magistrate Judge.

I. INTRODUCTION

Plaintiffs Barnes & Noble, Inc. and barnesandnoble.com LLC (collectively, "B&N") filed the instant action seeking a declaratory judgment of non-infringement and patent invalidity against defendants LSI Corporation and Agere Systems, Inc. (collectively, "Defendants"). Original Complaint, ECF No. 1.1 Defendants answered B&N's First Amended Complaint and brought counterclaims against B&N for patent infringement. Answer and Counterclaims, ECF No. 62.

On April 27, 2012, Defendants filed a Motion for Issuance of Letters Rogatory. Motion, ECF No. 106. No opposition to it has been filed. See N.D. Cal. Civ. L.R. 7-3(a) (providing that an opposition must be served and filed not more than 14 days after a motion is served and filed). Upon consideration of the motion, the letters rogatory submitted with it, and the relevant authority, the court GRANTS Defendants' motion.2

II. BACKGROUND

B&N seeks a declaratory judgment that their NOOK2122 line of eBook readers (the "Accused Products") does not infringe eleven of Defendants' patents relating to Wi-Fi, 3G, and audio technology. B&N has represented in its briefing in this case that "[i]n large part, the NOOK2122 functionality that is the subject of this case — functionality related to Wi-Fi, 3G, and audio — is implemented by components called `chips' that are supplied to [Plaintiffs] by third parties." B&N's Opposition to Motion to Dismiss, ECF No. No. 27, at 14. Through a physical investigation of the infringing products, Defendants have discovered that one or more of the components relevant to Defendants' infringement claims are made by CyberTAN Technology, Inc. ("CyberTAN"). Gabl Decl., ECF No. 110 at 2, ¶¶ 2-3, Exh. A.

Defendants believe that to complete their infringement contentions, they need not only the technical documentation about these products and components that is publicly available, but also additional design information that is not publicly available. Id. at 2, ¶ 4. Defendants attempted to serve a third party subpoena for documents on CyberTAN's U.S. affiliate, but that affiliate subsequently certified that it does not have responsive documents within its possession, custody or control. Id. at 2, ¶ 5, Exhs. B, C. Defendants further represent that CyberTAN is headquartered in Asia, and corporate records searches carried out by Defendants indicate that CyberTAN has offices in Taipei, Taiwan. Id. at 3, ¶ 6, Exh. D. In addition, Defendants are unable to serve a subpoena on CyberTAN because it has no U.S. offices or subsidiaries. Id. at 3, ¶ 7, Exh. D. Therefore, Defendants believe that they are unable to secure the information it requires from these parties through traditional discovery means. Memo, ECF No. 107 at 3.

III. LEGAL STANDARD

A letter rogatory is a formal written request sent by a court to a foreign court asking that the testimony of a witness residing within that foreign court's jurisdiction be taken pursuant to the direction of that foreign court and transmitted to the requesting court for use in a pending action. Marroquin-Manriquez v. I.N.S., 699 F.2d 129 (3rd Cir. 1983); 8A Charles Alan Wright, Arthur R. Miller & Richard L. Marcus, Federal Practice and Procedure § 2083 (3d ed. 2010). A letter rogatory can also include requests for the production of documents. See United States v. Reagan, 453 F.2d 165, 168 (6th Cir. 1971) (affirming district court's issuance of letters rogatory seeking documents from investigation conducted by German authorities). Federal Rule of Civil Procedure 28(b)(2) provides that a deposition may be taken in a foreign country "under a letter of request, whether or not captioned a `letter rogatory.'"

A court has inherent authority to issue letters rogatory. See Reagan, 453 F.2d at 172; United States v. Staples, 256 F.2d 290, 292 (9th Cir. 1958). 28 U.S.C. § 1781 also implicitly provides federal courts with authority to issue letters rogatory. 28 U.S.C. § 1781(a)(2).3 Whether to issue such a letter is a matter of discretion for the court. See United States v. Mason, 919 F.2d 139, 1990 WL 185894, 3 (4th Cir. 1990) (unpublished per curiam decision). When determining whether to exercise its discretion, a court will generally not weigh the evidence sought from the discovery request nor will it attempt to predict whether that evidence will actually be obtained. Asis Internet Services v. Optin Global, Inc., No. C-05-05124 JCS, 2007 WL 1880369, at *3 (N.D. Cal. Jun 29, 2007) (citing Sec. Ins. Co. of Hartford v. Trustmark Ins. Co., 218 F.R.D. 24, 27 (D. Conn. 2003); DBMS Consultants Ltd. v. Computer Assocs. Int'l, Inc., 131 F.R.D. 367, 369 (D. Mass. 1990); B & L Drilling Elecs. v. Totco, 87 F.R.D. 543, 545 (W.D. Okla. 1978)). A court's decision whether to issue a letter rogatory, though, does require an application of Rule 28(b) in light of the scope of discovery provided for by the Federal Rules of Civil Procedure. See Evanston Ins. Co. v. OEA, Inc., No. CIV S-02-1505 DFL PAN, 2006 WL 1652315, at* 2 (stating that Rule 28(b) "must be read together" with Rule 26(c) in determining whether to issue letter rogatory); see also DBMS Consultants Ltd., 131 F.R.D. at 369-70; B & L Drilling Elecs., 87 F.R.D. at 545.

IV. DISCUSSION

The discovery Defendants' request from CyberTAN is relevant and discoverable under the standard set forth in Rule 26 because, as described above, it may provide information about the design, operation and manufacture relating to the material functionalities of the Accused Products that is neither publicly available nor available via party discovery. See Fed. R. Civ. P. 26(b).4 Because CyberTAN is a business entities incorporated, headquartered and doing business in Taiwan, see Gabl Decl., ECF No. 110 at 3, ¶ 6, Ex. D, and all other efforts to obtain the discovery have failed, see id. at 2-3, ¶¶ 5, 7, the court finds that letters rogatory are necessary and appropriate mechanisms to request the desired discovery.

V. CONCLUSION

Defendants' Motion for Issuance of Letters Rogatory is GRANTED. The court will sign and affix its seal to each of the letters rogatory submitted and return the letters with original signatures and seals to Defendants' counsel for forwarding to the United States Department of State.

IT IS SO ORDERED.
