Aqua Connect v. TeamViewer: Remote Desktop Patent Suit Ends After 1,926 Days
Aqua Connect, Inc. and Strategic Technology Partners, LLC filed suit in Delaware against TeamViewer GmbH in December 2019, asserting two remote desktop patents against TeamViewer’s suite of remote access products. After more than five years of litigation, the parties jointly dismissed all claims and counterclaims with prejudice — each side bearing its own costs.
Five-Year Remote Desktop Patent Battle Ends in Mutual Walk-Away
Filed on 17 December 2019 in the District of Delaware before Judge Maryellen Noreika, this case pitted Aqua Connect, Inc. and co-plaintiff Strategic Technology Partners, LLC against TeamViewer GmbH — a Germany-based provider of remote access and support software. The plaintiffs asserted two patents, US8924502 and RE46386, covering remote desktop session management technology, against a range of TeamViewer products including TeamViewer, TeamViewer Host, TeamViewer QuickJoin, and TeamViewer QuickSupport, with version 13.2.14328 cited as representative.
The case closed on 26 March 2025 via a stipulated dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(ii), with all claims and counterclaims dismissed with prejudice. Critically, the parties agreed that each side would bear its own costs and fees. A dismissal with prejudice forecloses the plaintiffs from re-filing the same claims against TeamViewer — the dispute is permanently concluded on the merits as between these parties, without any court judgment on liability or damages.
A duration of 1,926 days — over five years — is notably extended even by the standards of complex patent litigation in Delaware. The symmetric cost arrangement and the use of Rule 41(a)(1)(A)(ii) joint stipulation strongly suggest a negotiated resolution, potentially including undisclosed licensing or business terms. The public record does not disclose whether any financial consideration changed hands, leaving the ultimate commercial outcome between the parties unknown.

Dismissed with prejudice: what the stipulated exit means for both parties
Rule 41(a)(1)(A)(ii) — joint stipulated dismissal with prejudice
Under FRCP 41(a)(1)(A)(ii), parties may jointly dismiss an action by filing a signed stipulation. Adding ‘with prejudice’ means the dismissal operates as a final adjudication on the merits — the plaintiffs cannot refile the same patent claims against TeamViewer in any court. This is a clean, bilateral exit that avoids a court-rendered judgment while permanently closing the dispute.
Permanent bar on refilingPlaintiffs permanently relinquish infringement claims against TeamViewer
By agreeing to dismissal with prejudice, Aqua Connect and Strategic Technology Partners surrendered their right to pursue these specific infringement claims against TeamViewer. The patents themselves remain valid and enforceable against third parties — the dismissal is party-specific, not patent-specific. Whether the plaintiffs secured any licensing revenue or other consideration in exchange is not disclosed in the public record.
Patents survive vs. third partiesTeamViewer exits with permanent protection from these patent claims
TeamViewer GmbH obtains a durable shield: Aqua Connect and Strategic Technology Partners are barred from asserting US8924502 and RE46386 against TeamViewer again. The symmetric costs arrangement — neither side recovers fees — suggests this was a negotiated conclusion rather than a capitulation by either party. TeamViewer was represented by DLA Piper LLP and Heyman Enerio Gattuso & Hirzel LLP throughout.
Permanent claim bar securedRemote access sector: these patents remain live threats for other players
The dismissal resolves only the TeamViewer dispute. US8924502 and RE46386 remain in force and could be asserted against other remote desktop and virtual desktop infrastructure (VDI) vendors. Competitors operating in the remote access space — including enterprise VDI, screen-sharing, and IT support software providers — should treat this case as a signal that these patents are actively monetised and should conduct FTO analysis accordingly.

Official order — verbatim text
The stipulation language — ‘dismiss all claims and counterclaims with prejudice, with each side to bear its own costs and fees’ — is precise and bilateral. The with-prejudice designation makes the dismissal res judicata as between these parties, extinguishing all asserted claims and TeamViewer’s counterclaims permanently. The mutual cost allocation departs from the default rule that costs follow the prevailing party, suggesting a negotiated resolution in which neither side characterised itself as the winner. No damages, no injunction, and no liability finding appear on the public docket.
US8924502 & RE46386 — Remote Desktop Session Management Patents
US8924502, filed under application number US14/035917, covers technology in the remote desktop and virtual desktop infrastructure (VDI) domain — specifically methods and systems relating to session management for remote access environments. RE46386, a reissued patent filed under application number US14/191450, represents a corrected or broadened reissuance of an earlier grant, typically indicating the patentee sought to strengthen or clarify claim scope after initial issuance. Reissued patents carry the original priority date, which may predate competing products by several years.
Together, these two patents form a targeted IP position around the core functionality that underpins commercial remote access software — session initiation, control, and management across networked endpoints. For the remote access sector, which has seen explosive growth driven by enterprise adoption of hybrid work tools, this patent pair represents a meaningful assertion risk. Any vendor offering screen-sharing, remote IT support, or virtual desktop products should treat the claims of US8924502 and RE46386 as live competitive IP requiring ongoing clearance analysis.
Should your team run an FTO against US8924502 and RE46386?
If your organisation develops or commercialises remote desktop software, VDI platforms, screen-sharing tools, IT remote support products, or any service involving multi-user remote session management, these two patents are directly relevant. The fact that Aqua Connect prosecuted this case for over five years against a major commercial defendant signals that the patent holder views these claims as broadly applicable and worth enforcing. Clearance should not be deferred to product launch.
PatSnap Eureka’s FTO Search Agent allows R&D and IP teams to map the independent and dependent claims of US8924502 and RE46386 against your product’s technical architecture, surface design-around options, and identify prior art that could support a validity challenge. Eureka also tracks the litigation history of both patents, so your team sees not just the text of the claims but the full enforcement posture before committing to a product roadmap.

What this case signals for the remote access software IP landscape
A five-year Delaware dispute ending in mutual walk-away raises pointed questions for any vendor in the remote desktop and VDI space.
Patents US8924502 and RE46386 remain enforceable against third parties
The with-prejudice dismissal protects only TeamViewer. Any other remote access, screen-sharing, or VDI vendor whose products overlap with the session management claims of these patents faces unreduced exposure. The active enforcement history makes these patents a credible litigation risk — not theoretical prior art.
Five-year duration signals hard-fought claim construction or damages disputes
Cases that run 1,926 days in Delaware before a joint stipulated exit typically involve protracted Markman proceedings, IPR petitions, or complex damages discovery. While the public record does not confirm which events extended the timeline, any future defendant asserting similar technology should budget for a multi-year campaign.
Aqua v TeamViewer — key questions answered
The case was dismissed with prejudice by joint stipulation on 26 March 2025, after 1,926 days of litigation. All claims and counterclaims were dismissed under FRCP 41(a)(1)(A)(ii), with each side bearing its own costs and fees. No damages award or liability finding appears on the public record.
Aqua Connect and Strategic Technology Partners asserted two patents: US8924502 (application no. US14/035917) and RE46386 (application no. US14/191450). Both patents cover remote desktop session management technology. RE46386 is a reissued patent, indicating broadened or corrected claims relative to the original grant.
Not necessarily. A stipulated dismissal with prejudice under Rule 41(a)(1)(A)(ii) is a bilateral agreement — it permanently bars the plaintiffs from refiling these claims against TeamViewer, but it does not constitute a court finding of non-infringement or invalidity. The mutual cost allocation suggests a negotiated resolution rather than a victory for either side.
Yes. The dismissal affects only the dispute between Aqua Connect, Strategic Technology Partners, and TeamViewer. The patents remain in force and can be asserted against other parties operating in the remote access, VDI, or screen-sharing space. No invalidity ruling was made in this case.
TeamViewer GmbH was represented by DLA Piper LLP (US) as lead counsel, with local Delaware support from Heyman Enerio Gattuso & Hirzel LLP. Named defence attorneys included Brian A. Biggs, Denise Seastone Kraft, Erin E. Larson, and Jeff Castellano.
