S3G Technology v. Advance Auto Parts — Dismissed With Prejudice in 140 Days
S3G Technology LLC filed suit against Advance Auto Parts in the Eastern District of Texas, asserting three software patents covering mobile application systems for iOS and Android. The parties jointly stipulated to dismiss all claims with prejudice just 140 days after filing, with each side bearing its own attorneys’ fees and costs.
Swift dismissal in mobile app patent dispute at Eastern District of Texas
On September 21, 2023, S3G Technology LLC filed a patent infringement action against Advance Auto Parts, Inc. in the U.S. District Court for the Eastern District of Texas (Case No. 5:23-cv-00095). S3G asserted three software patents — US9940124B2, US10261774B2, and US9081897B2 — targeting Advance Auto Parts’ iOS and Android mobile applications, along with the underlying server-side systems and non-transitory computer-readable storage media supporting those apps.
The case closed on February 8, 2024, when the court accepted a joint stipulation of dismissal with prejudice filed by both parties under Fed. R. Civ. P. 41(a)(1)(A)(ii). The dismissal is with prejudice, meaning S3G Technology is permanently barred from reasserting the same patent claims against Advance Auto Parts in future litigation. Each party was ordered to bear its own costs, expenses, and attorneys’ fees, with no prevailing-party fee award entered.
At 140 days from filing to closure, the resolution is notably rapid for a multi-patent software infringement case in the Eastern District of Texas — a venue that has historically attracted extended patent disputes. The speed and the mutual cost-bearing arrangement are consistent with either a confidential settlement between the parties or a strategic decision by S3G to abandon the action, though the public record is silent on which drove the outcome. No claim construction order or substantive ruling on the merits was issued.
Filing to dismissal in 140 days
140 days — faster than most patent infringement cases reach first substantive hearing
Dismissed with prejudice — what the stipulated order means for both parties
Stipulated dismissal under Rule 41(a)(1)(A)(ii)
The dismissal was filed as a joint stipulation signed by all appearing parties, requiring no court order to take effect under Fed. R. Civ. P. 41(a)(1)(A)(ii). The Eastern District court formally accepted the stipulation and entered the closure order. This mechanism is commonly used when parties have reached a resolution — whether a settlement or a mutual decision to end the dispute — without requiring a contested hearing.
No court order neededWith prejudice: S3G’s claims are permanently extinguished
A dismissal with prejudice carries full res judicata effect. S3G Technology LLC cannot refile these three patent infringement claims against Advance Auto Parts in any federal court. This is a materially stronger outcome for the defendant than a dismissal without prejudice, which would leave the door open to refiling. Notably, both parties agreed to this finality, which suggests the resolution was consensual rather than forced.
Bar on refilingEach party bears its own costs — no fee-shifting
The order expressly provides that all attorneys’ fees and costs are borne by the party that incurred them. Under 35 U.S.C. § 285, courts may award fees in ‘exceptional cases,’ but no such finding was made here. The mutual cost-bearing arrangement is the norm in stipulated dismissals and avoids any inference about which party prevailed — consistent with the confidential-settlement pattern seen in comparable Eastern District cases.
No § 285 fee awardEastern District of Texas filing strategy and rapid exit
S3G chose the Eastern District of Texas — a historically plaintiff-friendly patent venue — yet the case closed in 140 days without reaching claim construction. This pattern is frequently associated with patent assertion entities that file in favorable venues to apply settlement pressure. The quick, with-prejudice exit may reflect either a satisfactory confidential resolution or a reassessment of claim strength against a well-resourced defendant represented by DLA Piper.

Stipulation of dismissal — official text
The court’s order accepts a jointly filed stipulation, making clear that no merits determination was reached — neither infringement nor invalidity was adjudicated. The with-prejudice designation is the operative legal consequence: S3G Technology is permanently barred from asserting these three patents against Advance Auto Parts. The cost-neutrality clause signals a negotiated resolution rather than a concession of liability by either party. The public record does not disclose whether any financial consideration changed hands.
US9940124B2, US10261774B2 & US9081897B2 — Mobile App System Patents
The three patents asserted by S3G Technology — US9940124B2, US10261774B2, and US9081897B2 — originate from application numbers US15/065757, US15/947593, and US14/060490 respectively, suggesting a family spanning multiple filing generations. Their claims appear directed at systems and methods for modifying terminal machines and service-provider machines, computing architectures that execute or facilitate mobile application functionality, and non-transitory computer-readable storage media — a claim set broad enough to potentially read on standard iOS and Android app deployments across a wide range of industries.
The strategic significance of this portfolio lies in its functional, system-level claim framing rather than narrow implementation claims. Such claims are harder to design around because they target the architectural relationship between client devices and backend servers — a pattern inherent in virtually any modern retail mobile application. For the automotive aftermarket sector, where app-driven loyalty programs, parts lookup, and delivery scheduling are increasingly central to customer engagement, this patent family represents a non-trivial assertion risk that other operators in the space should evaluate independently of this case’s outcome.
Should your team run an FTO against US9940124B2, US10261774B2, and US9081897B2?
Any company operating consumer-facing iOS or Android mobile applications that interact with backend service-provider systems — particularly in retail, automotive aftermarket, e-commerce, or app-enabled services — should evaluate exposure to this S3G Technology patent family. The dismissal with prejudice in this case binds only Advance Auto Parts; it provides no legal protection to third parties. These patents remain in force and could support future assertions against other defendants.

What this case signals for the mobile app patent IP landscape
Short-lived but instructive: three software patents, a major retailer, and a swift exit in a historically assertive venue.
Mobile app system patents remain an active assertion vector
S3G’s three patents cover systems for modifying terminal and service-provider machines — broad functional claims that can be mapped onto diverse mobile app architectures. Retailers and e-commerce operators running iOS/Android apps should treat this portfolio as a live risk signal, even following this dismissal, as the patents remain in force.
Eastern District filings by PAEs often resolve before claim construction
Cases filed in the Eastern District of Texas by non-practicing entities disproportionately close before a Markman hearing. The 140-day lifespan of this case is consistent with that pattern and suggests defendants with strong counsel can often reach resolution without a substantive merits ruling — reducing but not eliminating ongoing patent risk.
S3G v Advance — key questions answered
S3G Technology LLC filed a patent infringement action against Advance Auto Parts Inc. in the Eastern District of Texas on September 21, 2023, asserting three software patents (US9940124B2, US10261774B2, US9081897B2) against AAP’s iOS and Android mobile apps. The case was dismissed with prejudice by joint stipulation on February 8, 2024 — 140 days after filing — with each party bearing its own costs.
US9940124B2, US10261774B2, and US9081897B2 are directed at systems and methods for modifying terminal machines and service-provider machines, computing devices running or supporting mobile applications, and non-transitory computer-readable storage media. The claim language is broad and functional, potentially reading on standard iOS and Android app architectures that interact with backend servers.
A dismissal with prejudice carries res judicata effect — S3G Technology is permanently barred from reasserting the same patent claims against Advance Auto Parts in any future action. The three patents remain in force as issued rights but cannot be used against this specific defendant in relation to the claims raised in Case No. 5:23-cv-00095.
No fee award was entered. The court’s dismissal order expressly provides that all attorneys’ fees, costs, and expenses shall be borne by the party that incurred them. No finding of an ‘exceptional case’ under 35 U.S.C. § 285 was made. This mutual cost-bearing arrangement is standard in stipulated dismissals and does not indicate liability by either party.
No. The with-prejudice dismissal applies only to claims between S3G Technology and Advance Auto Parts. US9940124B2, US10261774B2, and US9081897B2 remain active and enforceable against other parties. Retailers, app developers, or technology companies with similar mobile application architectures should conduct independent freedom-to-operate analysis against this patent family.
