Gametronics v. MSI: Signal Generation Patent Suit Ends in Dismissal With Prejudice
Gametronics LLC filed suit against Micro-Star International in the Eastern District of Texas asserting US8487872B2, covering apparatus and methods for generating data signals. After 414 days of litigation, Gametronics voluntarily dismissed the case with prejudice — permanently surrendering its right to re-assert these claims against MSI.
A data-signal patent assertion against MSI ends at plaintiff’s own hand
On June 18, 2024, Gametronics LLC filed a patent infringement action against Micro-Star International Co., Ltd. (MSI) in the Eastern District of Texas (Case No. 2:24-cv-00454), asserting US8487872B2, which covers an apparatus and method for generating data signals. MSI, a major Taiwan-based hardware manufacturer known for gaming peripherals, graphics cards, and motherboards, was targeted in a jurisdiction with a well-established history of patent assertion activity.
After 414 days of litigation, Gametronics filed a Notice of Dismissal voluntarily terminating the case with prejudice under Rule 41(a)(1)(A)(i). The court accepted the notice and ordered all pending claims dismissed with prejudice. Critically, the order specified that each party bears its own costs, expenses, and attorneys’ fees — meaning no fee-shifting award was made in either direction.
A with-prejudice dismissal initiated by the plaintiff before any court ruling on the merits typically suggests the parties reached some form of resolution, or that Gametronics determined continued litigation was not commercially viable. The public record does not disclose whether a confidential settlement was reached. What is certain is that Gametronics has permanently waived its right to bring these same claims under US8487872B2 against MSI in any future proceeding.

Dismissed with prejudice: what the voluntary termination means for both parties
Rule 41(a)(1)(A)(i) dismissal with prejudice explained
Under Rule 41(a)(1)(A)(i), a plaintiff may voluntarily dismiss an action without a court order before the defendant serves an answer or a motion for summary judgment. When that dismissal is expressly designated ‘with prejudice,’ it carries the full force of a final adjudication on the merits — the plaintiff permanently forfeits the right to re-litigate the same claims against the same defendant. The court here accepted the notice and formalised the dismissal by court order.
Voluntary — with prejudiceGametronics permanently barred from re-asserting against MSI
By filing a with-prejudice dismissal, Gametronics has extinguished its infringement claims under US8487872B2 as they relate to MSI. It cannot re-file the same action in any US court. The patent itself remains in force and Gametronics retains the right to assert it against other defendants — but the MSI enforcement avenue is closed permanently. The absence of a fee award means Gametronics avoided an adverse costs order.
Claims extinguished vs. MSIMSI achieves full dismissal — no liability, no ongoing exposure from this suit
MSI exits the litigation without any finding of infringement, without any damages award, and without any injunction. Crucially, the with-prejudice designation means Gametronics cannot return with the same patent claims. MSI also avoids any fee-shifting obligation — each party bears its own costs. The resolution is effectively a clean exit for the defendant, though it does not formally invalidate the asserted patent.
Full defence — no merits rulingUS8487872B2 survives — other hardware makers remain exposed
The dismissal with prejudice resolves this particular dispute but does not extinguish the patent itself. Gametronics retains US8487872B2 and may pursue other parties in the gaming hardware and electronics space. Companies manufacturing or distributing products involving data signal generation apparatus should monitor Gametronics’ assertion activity. The lack of any invalidity or non-infringement ruling means the patent’s claims remain untested on the merits.

Official order — verbatim text
The court’s order accepts Gametronics’ Notice of Dismissal under Rule 41(a)(1)(A)(i) and formalises the termination as with prejudice — the strongest form of voluntary dismissal available to a plaintiff. No merits determination was made; the court did not rule on infringement, validity, or claim construction. The mutual cost-bearing provision is consistent with a negotiated resolution or a plaintiff decision to exit without conceding liability. MSI’s position is fully protected against any refiling of these specific claims.
US8487872B2 — Apparatus and Method for Generating Data Signals
US8487872B2 (application no. US11/283603) covers an apparatus and method for generating data signals. The patent sits within the broader domain of electronic signal generation and processing — technology that underpins a wide range of digital hardware products including gaming peripherals, graphics processing interfaces, and communication controllers. The application number suggests filing in the mid-2000s timeframe, placing it in an era of rapid expansion in gaming and consumer electronics hardware architecture.
From a strategic standpoint, a patent claiming signal generation apparatus has potentially broad applicability across the gaming hardware ecosystem — covering anything from GPU output stages to peripheral data buses. MSI’s product portfolio, spanning graphics cards, motherboards, gaming mice, and keyboards, would plausibly intersect with such claims. The patent’s survival without any invalidity ruling means it remains a viable enforcement tool against other hardware manufacturers operating in adjacent product categories.
Should your product team run an FTO against US8487872B2?
Any company designing, manufacturing, or distributing products that involve data signal generation — including gaming GPUs, peripheral controllers, interface hardware, or signal processing integrated circuits — should consider whether US8487872B2 presents a freedom-to-operate risk. The dismissal with prejudice in this case resolved the MSI dispute but left the patent’s claims entirely untested on the merits, meaning the enforceability risk is undiminished for other market participants.

What this case signals for the gaming hardware IP landscape
A with-prejudice exit from E.D. Texas without a merits ruling leaves the underlying patent live — and the sector’s exposure unresolved.
With-prejudice exits often mask undisclosed resolutions — monitor closely
When plaintiffs voluntarily dismiss with prejudice before any substantive court ruling, it frequently suggests a confidential agreement was reached. Competitors and counsel should track Gametronics’ subsequent licensing and litigation activity to assess whether a licensing programme is being constructed around US8487872B2.
E.D. Texas remains a high-risk venue for hardware IP assertions
The Eastern District of Texas continues to attract patent assertion actions targeting hardware manufacturers. MSI’s engagement of Skadden, Arps, Slate, Meagher & Flom LLP suggests the case was treated as a serious threat from the outset. Hardware OEMs and component makers should maintain active patent monitoring for this jurisdiction.
