Social Positioning Input Systems v. SOS Co. (Dogtra): Voluntary Dismissal With Prejudice
Social Positioning Input Systems, LLC filed a patent infringement claim against SOS Co., Inc. — the maker of Dogtra GPS pet-tracking collars — asserting US9261365B2, covering remote address entry for positional information devices. The case ended in a voluntary dismissal with prejudice just 72 days after filing, before the defendant had answered.
GPS pet-tracker patent suit ends in 72-day voluntary exit
On 16 April 2024, Social Positioning Input Systems, LLC filed suit in the U.S. District Court for the Central District of California against SOS Co., Inc., doing business as Dogtra Co., a manufacturer known for GPS-enabled pet and dog-training tracking collars. The sole patent asserted was US9261365B2, which covers a device, system, and method for remotely entering, storing, and sharing addresses for a positional information device — a claim squarely relevant to networked GPS collar products.
The case closed on 27 June 2024 when plaintiff’s counsel at Garteiser Honea PLLC filed a Notice of Voluntary Dismissal with Prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Because SOS Co. had not yet served an answer or a motion for summary judgment, plaintiff was entitled to dismiss unilaterally. The ‘with prejudice’ designation is legally significant: it bars Social Positioning Input Systems from re-filing the same claims against SOS Co. on the same patent.
At 72 days, the litigation timeline is consistent with a pre-answer resolution — whether a licensing agreement, a commercial settlement, or a strategic decision to withdraw — though the public record does not disclose any financial terms. The speed of dismissal, before any substantive motion practice, suggests the parties may have reached an off-record arrangement, but that remains unconfirmed. Patent watchers should note that Garteiser Honea PLLC is a firm that frequently represents NPE plaintiffs, which may contextualise the filing strategy.

Voluntary dismissal with prejudice: what each party gains and loses
Rule 41(a)(1)(A)(i): plaintiff’s unilateral right to exit
Because SOS Co. had not yet served an answer or summary judgment motion, Social Positioning Input Systems could file a Notice of Voluntary Dismissal without court approval under Rule 41(a)(1)(A)(i). Adding ‘with prejudice’ converts what would normally be a dismissal without prejudice into a final adjudication on the merits — permanently closing this specific claim pathway against this defendant.
Rule 41(a)(1)(A)(i) — with prejudiceWith prejudice vs. without prejudice — why it matters here
A dismissal without prejudice would allow the plaintiff to refile the same patent claims against SOS Co. in the future. Dismissal with prejudice forecloses that option entirely — it is treated as a final judgment on the merits. The public record does not disclose why prejudice was stipulated; it may reflect a confidential resolution, a licensing deal, or a litigation strategy choice. The distinction carries real legal weight for both parties’ future freedom of action.
Bars refiling on same claimsSOS Co. (Dogtra) achieves permanent closure without answering
SOS Co. never needed to file a substantive response. The with-prejudice dismissal grants the defendant full protection from future suit by this plaintiff on US9261365B2. No costs award was recorded, so Dogtra achieved finality at minimal visible litigation cost. Whether any off-record commercial consideration was exchanged cannot be confirmed from the public docket.
No re-suit risk on US9261365B2Patent remains live — other GPS device makers remain exposed
The dismissal resolves only the dispute with SOS Co. US9261365B2 remains an issued, enforceable patent. Social Positioning Input Systems retains the right to assert the same claims against other manufacturers of GPS positional devices, including wearables, fleet trackers, and pet-location products. Companies in the connected-device GPS sector should treat this case as a signal that the patent is actively being monetised.

Official order — verbatim text
The dismissal notice expressly invokes Rule 41(a)(1)(A)(i) and confirms that SOS Co. had served neither an answer nor a summary judgment motion at the time of filing. The ‘with prejudice’ designation transforms what would otherwise be a procedural exit into a binding, merits-equivalent termination. Practically, this means the plaintiff cannot revive these specific infringement claims against SOS Co., though the underlying patent remains fully enforceable against third parties.
US9261365B2 — Remote address entry and sharing for GPS positional devices
US9261365B2, filed under application number US14/022193, protects a device, system, and method for remotely entering, storing, and sharing addresses for a positional information device. The patent sits at the intersection of GPS hardware and networked address management — covering the workflow by which a remote user inputs a destination or location address that is then stored and shared with a GPS-enabled endpoint device such as a tracker or collar.
For the connected-device sector, this patent presents a meaningful enforcement risk. GPS pet trackers, personal locators, and fleet-management hardware all rely on remote address or waypoint input functionality. An NPE holding this patent has a logical basis to approach multiple product categories. The Dogtra case suggests active monetisation is underway; competing hardware makers — particularly those in the consumer GPS wearables and animal-tracking segments — should treat this patent as a live enforcement threat.
Should you run an FTO against US9261365B2?
Any R&D or product team developing GPS-enabled devices with remote address entry, waypoint sharing, or location-data synchronisation features should assess their exposure to US9261365B2. This includes consumer pet trackers, personal safety devices, vehicle fleet trackers, and IoT asset-management systems. Given that the patent has already been asserted in an NPE campaign, the enforcement intent is confirmed — this is not a theoretical risk.

What this case signals for the GPS positional-device IP landscape
A fast, with-prejudice exit in an NPE suit often signals an off-record resolution — and leaves the asserted patent fully live against the rest of the market.
Pre-answer dismissals with prejudice often indicate confidential licensing
When an NPE plaintiff dismisses with prejudice before the defendant has answered, the most commercially rational explanation is that the parties reached a licensing or settlement agreement off the public record. Companies facing similar suits from Social Positioning Input Systems should weigh early licensing discussions against the cost of litigation.
US9261365B2 remains enforceable — GPS tracker makers should run FTO analysis
The patent covering remote address entry for positional devices survived this litigation intact. Any company selling GPS collars, asset trackers, or fleet-positioning hardware with remote address-input functionality should conduct a freedom-to-operate review against US9261365B2 before the next enforcement action.
Social v SOS — key questions answered
Social Positioning Input Systems, LLC filed a patent infringement suit against SOS Co., Inc. (Dogtra) in the Central District of California on 16 April 2024, asserting US9261365B2. The plaintiff voluntarily dismissed the case with prejudice on 27 June 2024 — 72 days after filing — before the defendant had answered, using Rule 41(a)(1)(A)(i). No merits ruling was issued.
Dismissal with prejudice bars Social Positioning Input Systems from suing SOS Co. again on the same patent and claims. However, US9261365B2 itself remains a valid, enforceable patent. The plaintiff retains full rights to assert it against other defendants in separate proceedings. The patent’s enforceability is not diminished by this dismissal.
The public record does not disclose the reason. A 72-day timeline ending before any substantive motion practice is consistent with a confidential licensing or settlement agreement, though that is unconfirmed. The with-prejudice designation suggests a deliberate, finalised resolution rather than a strategic withdrawal intended to refile later.
US9261365B2 covers a device, system, and method for remotely entering, storing, and sharing addresses for a positional information device. Products at potential risk include GPS pet and animal trackers, personal locator devices, vehicle fleet trackers, and other networked GPS hardware where a remote user inputs or shares location addresses. Companies in these segments should conduct FTO analysis.
Social Positioning Input Systems was represented by Christopher A. Honea and Randall T. Garteiser of Garteiser Honea PLLC. This firm is known for representing non-practising entity plaintiffs in patent assertion matters. No defendant counsel was recorded in the public docket, consistent with the case closing before SOS Co. formally appeared or answered.
