(LEAD CASE)

 MEMORANDUM ORDER

Before the Court is the Motion to Stay Pending Inter Partes Review and Ex Parte Review, 

filed by Cisco Systems, Inc., Hewlett Packard Enterprise Company, and Aruba Networks, LLC..

Dkt. No. 52. After consideration, the Court GRANTS the Motion to Stay.

I. BACKGROUND

Plaintiff Cobblestone Wireless, LLC filed complaints against Defendants Cisco Systems, 

Inc., Hewlett Packard Enterprise Company, and Aruba Networks, LLC on September 29, 2023, 

asserting infringement of U.S. Patent No. 7,924,802. On November 2, 2023, the Court consolidated 

these cases for all pretrial proceedings. Dkt. No. 15. On August 13, 2024 the Court issued an 

Amended Docket Control Order. Dkt. No. 60. Pursuant to that Order, the Claim Construction 

hearing was set for November 26, 2024, fact discovery closes on January 15, 2025, expert 

discovery ends on March 10, 2025, and trial is set to begin on June 23, 2025, among other 

deadlines. Id. 

On March 19, 2024 Cobblestone Wireless, LLC and Hewlett Packard Enterprise Company 

filed a petition for inter partes review on all asserted claims of the ’802 Patent. IPR2024-00707, 

Doc. 40. The Board instituted a trial for the ’802 Patent on September 24, 2024. Id., Doc. 26. A 

final written decision for the IPR is expected by September 24, 2025.

On June 25, 2024, all Defendants filed the current Motion to Stay, requesting that the Court 

stay this case until the Board has concluded IPR of the Asserted Patents. Dkt. No. 52. The matter is 

now fully briefed.

II. LEGAL STANDARD

“The party seeking a stay bears the burden of showing that such a course is appropriate.” 

Peloton Interactive, Inc. v. Flywheel Sports, Inc., No. 218-cv-390-RWS-RSP, 2019 WL 3826051, 

at *1 (E.D. Tex. Aug. 14, 2019) (quoting Realtime Data, LLC v. Hewlett Packard Enter. Co., No. 

6:16-cv-86-RWS-JDL, 2017 WL 3712916, at *3 (E.D. Tex. Feb. 3, 2017)); accord Landis v. N. 

Am. Co., 299 U.S. 248, 255 (1936). “The decision of whether to extend a stay falls solely within 

the court’s inherent power to control its docket.” Pers. Audio LLC v. Google, Inc., 230 F. Supp. 3d 

623, 626 (E.D. Tex. 2017) (citing ThinkOptics, Inc. v. Nintendo, No. 6:11-cv-455-LED, 2014 WL 

4477400, at *1 (E.D. Tex. Feb. 27, 2014)); accord Clinton v. Jones, 520 U.S. 681, 706 (“The 

District Court has broad discretion to stay proceedings as an incident to its power to control its own 

docket.”) (citing Landis, 299 U.S. at 254). 

District courts typically consider three factors when deciding whether to stay litigation 

pending IPR of the asserted patent(s): “(1) whether the stay will unduly prejudice the nonmoving 

party, (2) whether the proceedings before the court have reached an advanced stage, including 

whether discovery is complete and a trial date has been set, and (3) whether the stay will simplify 

issues in question in the litigation.” Trover Grp., Inc. v. Dedicated Micros USA, No. 2:13-CV1047-WCB, 2015 WL 1069179, at *2 (E.D. Tex. Mar. 11, 2015) (collecting cases). 

1 After Defendants filed the Motion on June 25, 2024, Cobblestone responded on July 9, 2024. Dkt. No. 52; Dkt. No. 

56. Defendants then replied on July 17, 2024, with Cobblestone filing their Sur-Reply on July 24, 2024. Dkt. No. 57; 

Dkt. No. 58.

III. ANALYSIS 

a. Inter Partes Review

i. Undue Prejudice

Defendants argue that Cobblestone will not suffer any undue prejudice if the Court grants a 

stay because Cobblestone does not make any products or compete with Defendants and, therefore, 

Cobblestone can be sufficiently compensated through monetary relief for any purported damages.

Dkt. No. 52 at 1, 6. Cobblestone counters by arguing that a stay would delay its interest in the 

timely enforcement of its patent rights. Dkt. No. 56 at 9-10. 

Cobblestone’s concern is entitled to some weight. Uniloc USA, Inc. v. Acronis, Inc., No. 

615-cv-1001-RWS-KNM, 2017 WL 2899690, at *2 (E.D. Tex. Feb. 9, 2017) (citing NFC Tech. 

LLC v. HTC Am., Inc., No. 2:13-CV-1058-WCB, 2015 WL 1069111, at *2 (E.D. Tex. Mar. 11, 

2015)). However, this factor is present in every case in which a patentee resists a stay, and is 

therefore not sufficient, standing alone, to defeat a motion to stay. Id. (citing NFC Tech., 2015 WL 

1069111, at *2); see also Trover, 2015 WL 1069179, at *2 (collecting cases). Where, as here, a 

patentee seeks exclusively monetary damages, as opposed to a preliminary injunction or other 

relief, “mere delay in collecting those damages does not constitute undue prejudice.” Id. (quoting 

SSL Servs., LLC v. Cisco Sys., Inc., No. 2:15-cv-433-JRG-RSP, 2016 WL 3523871, at *2 (E.D. 

Tex. June 28, 2016)) (citing VirtualAgility Inc. v. Salesforce.com, 759 F.3d 1307, 1318 (Fed. Cir. 

2014)). Nevertheless, since the final written decision for the IPR could issue after the scheduled 

trial, this factor weighs against a stay.

ii. Stage of the Case Proceedings

Defendants argue a stay is warranted because this case is still in its early stages, with 

significant pre-trial events yet to occur. Dkt. No. 52 at 6-7. Cobblestone counters that this case has 

Case 2:23-cv-00454-JRG-RSP Document 80 Filed 12/09/24 Page 3 of 5 PageID #:

716
4

been pending for nearly 10 months, with many documents produced and interrogatories answered. 

Dkt. No. 56 at 11.

“Usually, the Court evaluates the stage of the case as of the time the motion was filed.” 

Peloton Interactive, 2019 WL 3826051, at *5 (quoting Papst Licensing GMBH & Co., KG v. 

Apple, Inc., 6:15-cv-1095-RWS, slip op. at 7 (E.D. Tex. June 16, 2017)) (citing VirtualAgility, 759 

F.3d at 1317). The instant Motion was filed on June 25, 2024. Dkt. No. 52 at 10. At that point, a 

trial date had been set, Dkt. No. 37, and a Discovery Order had been entered, Dkt. No. 45.

However, Defendants are correct in asserting that large parts of discovery and many other 

important deadlines were still left at that point. Accordingly, this factor weighs in favor of a stay. 

iii. Issue Simplification 

Whether a stay “will result in simplification of the issues before a court is viewed as the 

most important factor when evaluating a motion to stay.” Uniloc USA, 2017 WL 2899690, at *3 

(citing Intellectual Ventures II LLC v. Kemper Corp., No. 6:16-cv-81-JRG, 2016 WL 7634422, at 

*2 (E.D. Tex. Nov. 7, 2016); NFC Tech., 2015 WL 1069111, at *4). “Simplification of the issues 

depends on whether the PTAB decides to grant the petition.” Id. (citing Trover, 2015 WL 1069179, 

at *4; Loyalty Conversion Sys. Corp. v. Am. Airlines, Inc., No. 2:13-cv-655-WCB, 2014 WL 

3736514, at *2 (E.D. Tex. July 29, 2014)).

Defendants contend that the IPR proceedings currently pending against Cobblestone’s

asserted patents will greatly simplify the issues for this Court. Dkt. No. 56 at 2. To demonstrate

this, Defendants need to show that every asserted claim has a reasonable likelihood of being 

invalidated by the Board for the Court to grant the Motion. Here, the Board has instituted a trial 

covering all asserted claims. IPR2024-00707 at 51. Accordingly, the simplification factor weighs in 

favor of a stay.

IV. CONCLUSION

The Court finds that, overall, the situation here merits a stay: the first factor for the IPR 

analysis weighs slightly against a stay, but the second and third factors—the third being the most 

important—weigh in favor. Accordingly, this case is STAYED pending further order. Counsel are 

directed to advise the Court by Notice within 14 days of any decision by the PTAB.
