Untitled case

This patent infringement litigation, case number 2:24-cv-00974, is being heard in the Eastern District of Texas. The plaintiff is K.Mizra LLC, which appears to be a non-practicing entity (NPE) or patent assertion entity (PAE), as its patent portfolio is noted to have "bounced around from monetization operation to monetization operation over the years." The defendants are Nokia Corporation, Nokia Solutions and Networks Oy, and Nokia of America Corporation, which are major operating companies in the telecommunications and networking industry. The lawsuit alleges that Nokia's networking products, including network operations solutions and router hardware, infringe K.Mizra's patents.

The primary patent at issue, as specified, is U.S. Patent No. 10,735,320, which generally concerns managing application traffic over a carrier network. In addition to the '320 patent, K.Mizra LLC has also asserted U.S. Patent No. 8,018,880, related to Layer 2 virtual private networks over Ethernet for faster traffic restoration after link failure, and U.S. Patent No. 9,749,249, pertaining to data traffic protection and redundancy in Layer 2 network traffic. The case is presided over by District Judge Rodney Gilstrap in the Marshall Division of the Eastern District of Texas. This venue is historically significant for patent litigation, often referred to as a "rocket docket" due to its plaintiff-friendly procedural rules, accelerated trial schedules, and a reputation for higher success rates for patent holders. While the Supreme Court's TC Heartland decision in 2017 aimed to restrict venue options, new litigation strategies, such as targeting foreign affiliates, have enabled plaintiffs to continue filing cases in the EDTX.

This case is notable due to the assertion of patents by an apparent NPE against a prominent operating company in the critical networking sector. The litigation has progressed to the claim construction phase, with a Memorandum Claim Construction Opinion and Order issued on April 14, 2026. The involvement of Nokia, a major player in telecommunications infrastructure, suggests potential industry impact. Furthermore, there is related activity concerning the '320 patent, including an inter partes review (IPR2025-01364) filed against K.Mizra LLC by Ciena Corporation, indicating challenges to the patent's validity.

Discovery Milestones

Details regarding specific discovery milestones with strategic significance are not available in the provided search results.

Trial Events, Verdict, and Post-Trial Motions

As of May 25, 2026, the case is ongoing, and there is no information indicating a trial, verdict, or post-trial motions.

Settlement, Dismissal, Judgment, or Appeal

Parallel PTAB IPR/PGR Proceedings

No information regarding parallel PTAB IPR (Inter Partes Review) or PGR (Post-Grant Review) proceedings specifically for U.S. Patent 10,735,320 was found in the search results. IPRs are typically filed within one year of a party being served with an infringement complaint. PGRs are available only for patents with an effective filing date on or after March 16, 2013, and must be challenged within nine months of the patent issuing. Without the patent's issuance date and the complaint's service date, it is difficult to determine if a PGR would have been timely or if an IPR could still be filed.The analyst has done a good job of extracting the key information available from the initial search, particularly identifying the Markman hearing and order dates. However, the subsequent searches were very broad and did not yield specific docket entries for the initial complaint, answer, or other key motions. The lack of specific docket event details for early pleadings and motions is a significant gap. Also, the PTAB search was very general and did not specifically target "10735320".

I will refine the search strategy to target specific docket events and to perform a more precise PTAB search.

Here's a plan for the next steps:

1. Search for Complaint and Answer: Conduct a more targeted search for docket entry 1 (complaint) and the defendant's answer/counterclaims in PACER or Justia Dockets for case 2:24-cv-00974, Eastern District of Texas. This should provide the filing dates and initial parties.
2. Search for Pre-Trial Motions: Use keywords like "motion to dismiss," "motion to transfer," "motion to stay," "summary judgment" combined with the case number to find relevant docket entries and their dispositions.
3. Detailed Markman Outcome: Review the content of the "MEMORANDUM CLAIM CONSTRUCTION OPINION AND ORDER" (Doc. 124) if accessible, or search for summaries of its findings to elaborate on the claim construction outcome for U.S. Patent 10,735,320.
4. Discovery Milestones: Search for docket entries related to scheduling orders, discovery disputes, or motions to compel that might indicate strategic discovery milestones.
5. Current Posture/Outcome: Reiterate that the case is ongoing, and continue to monitor for settlement, dismissal, judgment, or appeal, looking for any recent activity since April 2026.
6. Targeted PTAB Search: Perform a direct search on the USPTO PTAB database for "US Patent 10735320" to identify any IPR or PGR proceedings. This is crucial for understanding parallel proceedings.

The current output will be used as a base, and the new information will be appended chronologically.## Key Legal Developments and Outcome for Patent Infringement Litigation (2:24-cv-00974)

This patent infringement lawsuit, K.Mizra LLC v. Nokia Corporation et al., was filed in the Eastern District of Texas under case number 2:24-cv-00974, asserting U.S. Patents 10,735,320, 8,018,880, and 9,749,249. The litigation is ongoing.

Filing & Initial Pleadings

• Complaint Filed: K.Mizra LLC filed its complaint for patent infringement on November 25, 2024, against Nokia Corporation, Nokia Solutions and Networks Oy, and Nokia of America Corporation. The complaint alleges infringement of U.S. Patent 10,735,320, which concerns "manag[ing] application traffic over a carrier network," U.S. Patent 8,018,880 related to Layer 2 virtual private networks, and U.S. Patent 9,749,249 concerning "data traffic protection and redundancy" in Layer 2 network traffic.
• Partial Dismissal of Defendants: On August 12, 2025, District Judge Rodney Gilstrap granted an "UNOPPOSED SEALED MOTION to Dismiss Without Prejudice" filed by K.Mizra LLC, which terminated Nokia Corporation and Nokia Solutions and Networks Oy as defendants. This left Nokia of America Corporation as the sole remaining defendant.

Pre-trial Motions of Substance

• Motion for Leave to Supplement Invalidity Contentions: On August 6, 2025, Nokia's "Sealed Motion for Leave to Supplement Invalidity Contentions" was granted. These contentions relate to the invalidity of U.S. Patent 10,735,320, citing prior art such as U.S. Patent No. 7,477,657 ("Murphy") for anticipation and obviousness.
• Motion for Partial Summary Judgment: As of May 8, 2026, Nokia of America Corporation filed a "SEALED MOTION for Partial Summary Judgment No. 1: Festo Bars the Doctrine of Equivalents for the '354 Patent." Replies to this motion were exchanged on the same date. The specific patent ('354) mentioned in this motion is not among the three listed as at issue in the claim construction order, which focused on 10,735,320, 8,018,880, and 9,749,249. Further details would be needed to clarify if this relates to a different patent in the broader litigation or an erroneous reference.

Claim Construction (Markman) Outcomes

• Markman Hearing: A Markman hearing was held on March 31, 2026.
• Claim Construction Opinion and Order: District Judge Rodney Gilstrap signed a "MEMORANDUM CLAIM CONSTRUCTION OPINION AND ORDER" on April 14, 2026 (Docket No. 124). This order addressed three claim scope disputes. For U.S. Patent 8,018,880, the disputes concerned "Virtual Switch Instance" (VSI) and the meaning of a control plane being "external to the plurality of sites." For U.S. Patent 9,749,249, the dispute was about what it means to "preempt" traffic on a standby pseudowire. The opinion specifically concerned U.S. Patent 10,735,320 regarding managing application traffic.

Discovery Milestones

Beyond Nokia's granted motion to supplement invalidity contentions in August 2025, specific strategic discovery milestones are not detailed in the available information.

Trial Events, Verdict, and Post-Trial Motions

As of May 25, 2026, the case is ongoing. There is no public information indicating that the case has proceeded to trial, reached a verdict, or involved post-trial motions.

Settlement, Dismissal, Judgment, or Appeal

The litigation is active and has not reached a final disposition via settlement, judgment, or appeal. The partial dismissal of certain Nokia entities occurred early in the litigation.

Parallel PTAB IPR/PGR Proceedings

• IPR2025-01364: A parallel Inter Partes Review (IPR) proceeding, IPR2025-01364, was initiated by Ciena Corporation against K.Mizra LLC, challenging U.S. Patent 10,735,320. This IPR proceeding references the district court case 2:24-cv-00974. The IPR challenges the '320 patent based on anticipation and obviousness in view of prior art, including U.S. Patent No. 7,477,657 ("Murphy"). The outcome or current status of IPR2025-01364 is not specified in the provided information, nor is its effect on the ongoing district court litigation explicitly stated, though the existence of such a challenge often leads to motions to stay district court proceedings, particularly if institution is granted. No information regarding Post-Grant Review (PGR) proceedings for any of the asserted patents was found.
