Communication Interface Technologies v. Pure Hockey — Dismissed in 42 Days
Communication Interface Technologies, LLC asserted three communication interface patents against Pure Hockey, LLC’s mobile app in the Eastern District of Texas. The case was voluntarily dismissed without prejudice just 42 days after filing, before the defendant had even answered the complaint.
Pre-answer voluntary dismissal in mobile app communication IP dispute
On 9 January 2024, Communication Interface Technologies, LLC filed a patent infringement action against Pure Hockey, LLC in the Eastern District of Texas (Case No. 4:24-cv-00020), before Chief Judge Sean D. Jordan. The complaint asserted three patents — US6574239B1, US8291010B2, and US8266296B2 — all directed at communication interface technology, against the Pure Hockey App.
The case closed on 20 February 2024, just 42 days after filing, when the plaintiff filed a notice of voluntary dismissal without prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1). Because Pure Hockey had not yet served an answer to the complaint, the plaintiff was entitled to dismiss as of right, without requiring a court order. Each party was ordered to bear its own costs, expenses, and attorneys’ fees.
The 42-day duration is notably brief and suggests resolution before substantive litigation commenced. The without-prejudice designation means Communication Interface Technologies retains the right to refile these claims in the future, leaving the underlying infringement question unresolved on the merits. The public record does not disclose whether a private settlement or licence agreement was reached between the parties.
Filing to resolution in 42 days
42 days — resolved before defendant’s first responsive pleading
Voluntary dismissal under FRCP 41(a)(1) — what this means for both parties
FRCP 41(a)(1): dismissal as of right before answer
Federal Rule of Civil Procedure 41(a)(1) allows a plaintiff to dismiss an action without a court order at any time before the defendant serves an answer or a motion for summary judgment. Because Pure Hockey had not yet answered the complaint, Communication Interface Technologies could file a notice of dismissal unilaterally. No judicial approval was required, making this one of the most efficient exit mechanisms available in US federal litigation.
No court order requiredWithout prejudice: refiling rights remain open
A dismissal without prejudice does not resolve the underlying claims on the merits. Communication Interface Technologies retains the right to refile the same patent infringement allegations against Pure Hockey in the future. The public record is silent on whether any licence, settlement payment, or covenant not to sue accompanied this dismissal — that distinction is material to assessing whether this represents a commercial resolution or a strategic pause.
Refiling rights preservedEach party bears own costs — no fee-shifting triggered
The dismissal notice specified that each party shall bear its own costs, expenses, and attorneys’ fees. In patent cases, fee-shifting under 35 U.S.C. § 285 requires a finding of an ‘exceptional case,’ which typically follows substantive litigation. Given the pre-answer dismissal, no such finding was sought or granted here. The mutual cost-bearing arrangement is consistent with a negotiated exit rather than a unilateral abandonment.
No § 285 fee award42-day timeline suggests early commercial resolution or reassessment
Cases dismissed this quickly — before the defendant has retained counsel of record or filed any pleading — typically reflect one of two scenarios: an early licensing discussion that reached a conclusion, or a plaintiff reassessing the strength or economics of the case after filing. The absence of any defendant law firm on record suggests Pure Hockey had not yet formally engaged litigation counsel, which may have accelerated or simplified any negotiation.

Stipulation of dismissal — official text
The dismissal notice invokes FRCP 41(a)(1) explicitly, confirming this was a plaintiff-initiated exit requiring no judicial intervention. The without-prejudice designation is the most legally significant term: the three asserted patents remain valid and enforceable, and Pure Hockey has no guarantee against future assertions on the same grounds. The mutual cost-bearing clause, while standard in such notices, suggests the parties reached at least a procedural understanding, if not a broader commercial one.
US6574239B1, US8291010B2 & US8266296B2 — Communication Interface Technology
The three patents asserted — US6574239B1, US8291010B2, and US8266296B2 — all fall within the communication interface technology domain. US6574239B1 originates from application US09/167698, while US8291010B2 and US8266296B2 stem from later applications (US12/194311 and US12/272481 respectively), suggesting a family of related innovations developed over time. These patents were asserted against the Pure Hockey App, indicating the claimed technology relates to how applications communicate, manage data sessions, or interface with backend systems.
Communication interface patents of this type are frequently asserted against mobile application developers because the underlying technical concepts — session management, data transmission protocols, interface architecture — are broadly applicable across app categories. For retailers operating mobile commerce or engagement apps, these patents represent a category risk. The fact that three patents were bundled in a single complaint against a single product suggests the plaintiff views them as a coordinated portfolio rather than isolated assets.
Should you run an FTO against US6574239B1, US8291010B2, and US8266296B2?
Any company operating a consumer-facing mobile application — particularly in retail, sports, or e-commerce — should assess exposure to this patent family. The Pure Hockey App was the specific target here, but the breadth of communication interface claims means comparable apps with similar architectural features could face equivalent assertions. Product and engineering teams building or updating app communication layers should treat these patents as live risk, not resolved precedent.
PatSnap Eureka’s FTO Search Agent can map your app’s technical architecture against the claim scope of US6574239B1, US8291010B2, and US8266296B2, identifying potential overlap before it becomes litigation exposure. Setting up a claim monitoring alert for this patent family also ensures you are notified if Communication Interface Technologies or a successor entity files further assertions, giving your legal team lead time to prepare a response strategy.

What this case signals for the mobile app and communication IP landscape
A three-patent assertion resolved in 42 days before any defence filing raises questions about enforcement strategy and licensing dynamics in communication interface IP.
Communication interface patents remain active assertion tools against app developers
This case is consistent with a broader pattern of communication interface patent assertions targeting mobile applications. Companies operating consumer-facing apps — particularly in retail and sports — should audit their app’s backend communication architecture against patents in this family. A pre-litigation FTO review is significantly cheaper than even a pre-answer dismissal.
Eastern District of Texas remains a preferred venue for early-stage patent assertions
The Eastern District of Texas continues to attract patent infringement filings, even for cases that resolve quickly. Filing here signals plaintiff intent to leverage the district’s plaintiff-friendly reputation as a negotiating tool. Defendants served with complaints in this district should move quickly to assess settlement economics before litigation costs escalate.
Communication v Pure — key questions answered
Communication Interface Technologies, LLC filed a patent infringement complaint against Pure Hockey, LLC on 9 January 2024 in the Eastern District of Texas, asserting three communication interface patents against the Pure Hockey App. The plaintiff voluntarily dismissed the case without prejudice on 20 February 2024 — 42 days after filing — before the defendant had answered the complaint.
Communication Interface Technologies asserted three patents: US6574239B1 (application US09/167698), US8291010B2 (application US12/194311), and US8266296B2 (application US12/272481). All three are directed at communication interface technology and were asserted against the Pure Hockey App specifically.
Dismissal without prejudice means the case was terminated without a ruling on the merits, and Communication Interface Technologies retains the right to refile the same claims against Pure Hockey in the future. The three asserted patents remain valid and enforceable. It is distinct from a dismissal with prejudice, which would permanently bar the plaintiff from bringing the same claims again.
The case was dismissed just 42 days after filing under FRCP 41(a)(1), which permits a plaintiff to dismiss without court approval before the defendant files an answer. The speed of resolution — and the absence of any defence counsel on the docket — is consistent with either an early licensing agreement or a decision by the plaintiff to reassess the case. The public record does not disclose the reason for the dismissal.
The dismissal notice stipulated that each party shall bear its own costs, expenses, and attorneys’ fees. No fee award was made under 35 U.S.C. § 285 — such awards require a finding of an exceptional case, which was not pursued given the pre-answer, pre-substantive-litigation posture of the dismissal.
