ORDER GRANTING DEFENDANT’S MOTION TO STAY PENDING REEXAMINATION
Plaintiffs bring this action against Defendant asserting infringement of U.S. *1051 Patent Nos. 5,809,492 (the “'492 Patent”), 5,922,045 (the “'045 Patent”), 6,118,976 (the “'976 Patent”) and 6,983,478 (the “'478 Patent”) (collectively, the “patents-in-suit”). The parties are presently before the Court on Defendant’s Motion to Stay Pending Reexamination. Dkt. 63. Having read and considered the papers filed in connection with this matter and being fully informed, the Court hereby GRANTS Defendant’s Motion to Stay. The Court, in its discretion, finds this matter suitable for resolution without oral argument. See Fed.R.Civ.P. 78(b).
I. BACKGROUND
On March 12, 2010, Plaintiffs filed this action against Defendant asserting infringement of the patents-in-suit. The initial case management conference occurred on June 24, 2010, during which the Court set the claim construction hearing for January 27, 2011. Dkt. 34. No trial date has been set. Plaintiffs filed a First Amended Complaint (“FAC”) оn December 17, 2010. On January 20, 2011, Defendant filed its Answer and Counterclaims, asserting counterclaims seeking declaratory judgment of non-infringement and invalidity of the patents-in-suit. Dkt. 83.
Meanwhile, on December 3, 2010, Defendant filed a inter partes reexamination request with the U.S. Patent and Trademark Office (“PTO”) for the '478 Patent. 1 Mouzari Decl. Ex. 6, Dkt. 63-1. On that same day, Defendant also filed with the PTO ex paute reexamination requests for the '492 Patent, the '045 Patent, and the '976 Patent. Id. Exs. 7-9. Defendant’s four reexamination requests collectively ask the PTO to reexamine all of the patent claims asserted in this аction.
On December 6, 2010, Defendant filed the instant Motion to Stay Pending Reexamination. Dkt. 63. Plaintiffs oppose Defendant’s motion. On December 29, 2010, the Court vacated the January 27, 2011 claim construction hearing pending resolution of Defendant’s motiоn to stay. Dkt. 78. After the close of briefing on the stay motion, Defendant filed a notice with this Court indicating that the PTO has granted Defendant’s requests for reexamination with respect to all four patents-in-suit. Dkt. 84.
II. LEGAL STANDARD
“A patent is presumed to be valid, and this presumption only can be overcome by clear and convincing evidence to the contrary.”
Enzo Biochem, Inc. v. Gen-Probe Inc.,
There is a “liberal policy in favor of granting motions to stay proceedings pending the outcome of USPTO reexamination or reissuance proceedings.”
ASCII Corp. v. STD Entm’t,
III. ANALYSIS
A. Stage of the Litigation
The early stage of a litigation weighs in favor of granting a stay pending reexamination.
See Target Therapeutics, Inc. v. SciMed Life Sys., Inc.,
Here, Plaintiffs filed their complaint in March 2010. The parties have not exchanged expert reports, conducted any depositions, or filed any dispositive motions. Mouzari Decl. ¶¶ 12-13. While claim construction briefs have been filed, the clаim construction hearing was vacated, and no trial date is currently scheduled.
Nevertheless, Plaintiffs argue that this litigation should not be stayed because it is in its “advanced stages.” In support of that argument, Plaintiffs note that the parties have completed briefing on claim construction, and argue that, under similar circumstances, courts have denied requests for stay. Plfs.’ Opp. at 2. However, the cases that Plaintiffs rely upon are distinguishable. For example, the defendants in
Roy-G-Biv Corp. v. Fanuc Ltd.,
In view of the circumstances of this case, the Court finds that the first factor militates in favor of a stay.
B. Simplification of the Issues and Trial
The second factor examines whether a stay pending reexamination will simplify the issues in question and trial of the case. As explained by the Federal Circuit: “[o]ne purpose of the reexamination procedure is to eliminate trial of that issue (when the claim is canceled) or to facilitate trial of that issue by providing thе district
*1053
court with the expert view of the PTO (when a claim survives the reexamination proceeding).”
Gould v. Control Laser Corp., 705
F.2d 1340, 1342 (Fed.Cir.1983);
see also Ho Keung Tse v. Apple Inc.,
In this case, granting a stay pending issuance of a reexamination certificate will significantly narrow invalidity issues as to the '478 Patеnt, which is undergoing inter partes reexamination proceedings. Specifically, under 35 U.S.C. § 315(c), a third-party requester (here, Defendant) “is es-topped from asserting at a later time, in any civil action ... the invalidity of any claim finally determined to be valid and patentable on any ground which the third-party requester raised or could have raised during the inter partes reexamination proceedings.” 35 U.S.C. § 315(c). Simplifying invalidity challenges directed to the '478 Patent would provide a benefit because invalidity comprises a signifiсant part of patent litigation. Moreover, the simplification of issues would be substantial, as Defendant would be estopped from asserting invalidity on any ground that Defendant “raised or could have raised” during the reexamination procеedings. See 35 U.S.C. § 315(c).
Also, while Section 315(c) is not applicable to Defendant’s
ex parte
reexamination requests directed to the other three patents-in-suit, a stay pending reexamination of those patents would nevertheless simplify the issues and trial in this case. Here, Plaintiffs’ claims are only for patent infringement, and Defendant’s counterclaims are limited to requests for declaratory relief — asking the Court to declare that the patents-in-suit are invalid and not infringed by Defendant. There are no issues in the case unrelated to patent infringement for which the PTO’s expertise resulting from the reexamination would not be helpful.
Cf. Yodlee, Inc. v. Ablaise Ltd.,
In response, Plaintiffs argue that a stay is inappropriate because the reexaminations are unlikely to cancel or modify all of the patent claims at issue. However, this Court has recognized that “if the reexamination proceeding should narrow
any
of the assertеd claims of the [patent-in-suit], the scope of th[e] litigation may be significantly simplified.”
Ho Keung Tse,
*1054 In sum, a stay pending final resolution of the reexamination proceedings would simplify the issues in question and trial, weighing in favor of a stay.
C. Prejudice and Tactical Concerns
The third factor examines whether a stay would unduly prejudice or present a clear tactical disadvantage to the nonmoving party. It should be noted that “delay inherent in the reexamination process does not constitute, by itself, undue prejudice.”
Esco Corp. v. Berkeley Forge & Tool, Inc.,
Because delay inherent in the reexamination process does not constitute undue prejudice, courts also consider evidence of dilatоry motives or tactics, such as when a party unduly delays in seeking reexamination of a patent.
See KLA-Tencor Corp. v. Nanometrics, Inc.,
At bottom, Plaintiffs have failed to show, beyond the delay implicit in the reexamination process, how they would be unduly prejudiced or tactically disadvantaged if this Cоurt were to grant a stay. Therefore, this factor weighs in favor of granting a stay.
IV. CONCLUSION
For the above stated reasons,
IT IS HEREBY ORDERED THAT:
1. Defendant’s Motion to Stay (Dkt. 63) is GRANTED. This action is STAYED pending final exhaustion of all four pending reexamination proceedings, including any appeals. 2
2. The Clerk shall ADMINISTRATIVELY CLOSE this matter.
*1055 3. The parties are instruсted to submit status reports to the Court every six months, apprising the Court of the status of the pending reexamination proceedings. The parties are advised that the failure to submit such status reports could result in dismissal of this matter.
4. Upon final exhaustiоn of all four pending reexamination proceedings, including any appeals, the parties shall jointly submit to the Court, within one week, a letter indicating that all appeals have been exhausted, and requesting that this matter be reopеned and a case management conference be scheduled.
5. This Order terminates Docket 63.
IT IS SO ORDERED.
Notes
. An
inter partes
proceeding allows third parties to have a role in the reexamination process, while an
ex parte
proceeding does not.
See Cooper Techs. Co. v. Dudas,
. While the Court orders this action stayed pending final exhaustion of all four pending reexamination proceedings, this Order does not foreclose any party from moving to reopen this action prior to completion of all of the reexamination proceedings upon a showing of compelling circumstances.
