After 840 days of litigation in the Western District of Texas before Judge Alan D. Albright, Kortek Industries Pty., Ltd. voluntarily dismissed its patent infringement action against Chengdu Meross Technology Co., Ltd. without prejudice on August 29, 2024. The suit, filed May 12, 2022 under Case No. 6:22-cv-00490, centered on five U.S. patents—US10862313B2, US9590427B2, US9923376B2, US10429869B2, and US9465377B2—covering WiFi-enabled power control and smart-home device technologies. Meross-branded smart plugs, switches, LED lighting, air purifiers, and garage door openers were named as accused products. The dismissal was filed unilaterally under Fed. R. Civ. P. 41(a)(1)(A)(i), with each party bearing its own costs.

This case carries important strategic signals for the smart-home and IoT patent ecosystem. A voluntary dismissal without prejudice—particularly before the defendant filed any responsive pleading—preserves Kortek’s right to re-file, keeping litigation risk alive for Meross and similarly situated IoT device manufacturers. For patent attorneys, in-house IP teams, and R&D leaders working in the WiFi-enabled device space, understanding the patents at issue and the procedural posture of this case is essential for accurate freedom-to-operate assessments and competitive intelligence.

Case Overview

The Parties

The Patents at Issue

The five asserted patents—US10862313B2, US9590427B2, US9923376B2, US10429869B2, and US9465377B2—collectively cover systems and methods for remotely controlling electrical power outlets, switches, and connected devices over WiFi networks, including real-time monitoring, scheduling, and energy management functionality. These inventions underpin the core architecture of modern smart-home ecosystems, enabling smartphone and cloud-based control of household appliances and lighting. Real-world applications include smart plugs, smart switches, intelligent lighting strips, and IoT-enabled garage door and air quality controllers—precisely the product categories accused in this litigation.

Litigation Timeline & Procedural History

The case was filed on May 12, 2022, in the U.S. District Court for the Western District of Texas—a venue that, under Chief Judge Alan D. Albright, became one of the most popular patent litigation forums in the country due to its patent-friendly procedures, rapid scheduling orders, and willingness to maintain cases through trial. Filing in this district signaled Kortek’s intent to pursue an aggressive litigation posture, as Judge Albright’s court is well known for denying transfer motions and moving cases efficiently toward trial.

Despite the venue’s reputation for speed, this case ran for 840 days—approximately 28 months—before closing on August 29, 2024. The resolution came not through a trial verdict, claim construction ruling, or summary judgment, but via a unilateral voluntary dismissal without prejudice filed by Kortek under Fed. R. Civ. P. 41(a)(1)(A)(i). Critically, the record indicates that Chengdu Meross Technology never served an answer or a motion for summary judgment, which is the procedural prerequisite enabling a plaintiff to dismiss without court approval. This suggests the parties may have reached an out-of-court resolution—or that Kortek made a strategic decision to withdraw and potentially re-file under more favorable circumstances—without any merits adjudication.

The Verdict & Legal Analysis

Outcome

Kortek Industries Pty., Ltd. voluntarily dismissed this action without prejudice pursuant to Fed. R. Civ. P. 41(a)(1)(A)(i), with each party bearing its own costs and expenses. No damages were awarded, no injunctive relief was issued, and no merits determination was made on any of the five asserted patents. Because the dismissal was without prejudice, Kortek retains the right to re-file infringement claims against Chengdu Meross Technology or related parties in the future.

Verdict Cause Analysis

The voluntary dismissal without prejudice reflects a procedurally significant resolution that forecloses no substantive rights for Kortek while ending the immediate litigation against Meross.

• Kortek invoked Fed. R. Civ. P. 41(a)(1)(A)(i), which permits a plaintiff to dismiss an action as of right—without court approval—provided the defendant has not yet served an answer or a motion for summary judgment, a condition confirmed by the case record.
• The dismissal was entered without prejudice, meaning none of the five asserted patents (US10862313B2, US9590427B2, US9923376B2, US10429869B2, US9465377B2) received a validity or infringement determination, and Kortek is not barred from asserting them again.
• Each party was ordered to bear its own costs and expenses, indicating no fee-shifting occurred under 35 U.S.C. § 285 or otherwise, and neither party was adjudicated a prevailing party for cost purposes.
• The 840-day duration before dismissal—with no answer filed by the defendant—raises strategic questions about whether a licensing negotiation, business agreement, or enforcement prioritization shift drove the plaintiff’s decision to withdraw.

Legal Significance

1. A Rule 41(a)(1)(A)(i) dismissal without prejudice in a multi-patent smart-home case creates ongoing freedom-to-operate uncertainty for IoT device manufacturers, since the asserted patents remain fully enforceable and no claim scope has been judicially interpreted.
2. The absence of any responsive pleading from Chengdu Meross Technology throughout the 840-day pendency is an unusual procedural posture that may indicate the defendant pursued extra-judicial resolution strategies—such as direct licensing negotiations—rather than engaging in formal patent defense.
3. This case reinforces that the Western District of Texas under Judge Albright remains a strategically significant venue for patent plaintiffs even when cases resolve short of trial, as the venue’s reputation alone may exert settlement pressure on defendants, particularly foreign-based manufacturers.

Strategic Takeaways

For Patent Attorneys:

• When representing IoT or smart-home defendants facing a multi-patent complaint in the Western District of Texas, consider the strategic value of early responsive pleadings—serving an answer promptly removes the plaintiff’s unilateral right to dismiss under Rule 41(a)(1)(A)(i) and forces any exit to require court approval or bilateral agreement.
• Kortek’s five asserted patents cover core WiFi power-control architecture; counsel advising clients in adjacent smart-home product categories should conduct proactive claim mapping against these patents before assuming the litigation risk has passed.
• The without-prejudice nature of this dismissal means all five patents remain live litigation vehicles—attorneys should monitor Kortek’s filing activity for re-filing in Texas or alternative venues, including the ITC, which could broaden the exclusion remedy against imported smart-home devices.
• The fee-neutrality outcome (each party bears its own costs) with no prevailing-party determination is a reminder that early-stage voluntary dismissals rarely create the ‘exceptional case’ predicate needed for attorney’s fee awards under 35 U.S.C. § 285.

For IP Professionals:

• In-house IP teams at companies manufacturing WiFi-enabled smart-home devices should flag US10862313B2, US9590427B2, US9923376B2, US10429869B2, and US9465377B2 for active FTO monitoring, as Kortek retains full enforcement rights and has demonstrated willingness to litigate in favorable U.S. venues.
• The lack of any public settlement terms means licensing benchmarks for these patents cannot be inferred from this case—IP teams should seek independent valuation of Kortek’s portfolio before entering any licensing discussions triggered by a demand letter or re-filed complaint.

For R&D Teams:

• R&D and product teams developing WiFi-enabled smart plugs, switches, lighting controls, or energy management devices should conduct targeted design-around analyses against the five Kortek patents to identify whether product architectures can be modified to fall outside the asserted claims without compromising core functionality.
• Given that Meross-branded smart plugs, LED lighting, air purifiers, and garage door openers were all named as accused products, engineering teams working on any combination of these IoT categories should treat Kortek’s portfolio as an active risk and incorporate FTO clearance reviews into their product development lifecycle.
