Web 2.0 Technologies & Pennar Software v. Miro: Dismissed With Prejudice After 398 Days
Web 2.0 Technologies, LLC and Pennar Software Corporation brought a two-patent infringement action against Realtimeboard, Inc. (trading as Miro) in Delaware District Court, asserting patents covering online collaboration and access-control technology against Miro’s widely-used collaborative whiteboard platform. The parties jointly stipulated to dismiss all claims with prejudice after 398 days, with each side bearing its own costs.
Two-Patent Collaboration Software Suit Against Miro Ends in Prejudicial Dismissal
On 3 January 2023, Web 2.0 Technologies, LLC and co-plaintiff Pennar Software Corporation filed suit against Realtimeboard, Inc., the company behind the Miro online collaborative whiteboard platform, in the District of Delaware before Judge Maryellen Noreika. The plaintiffs asserted two United States patents — US8117644B2 and US6845448B1 — against Miro’s core product, which enables distributed teams to brainstorm, plan, and manage agile workflows through a shared digital canvas.
The case closed on 5 February 2024 when the parties filed a joint stipulation of dismissal with prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(ii). All claims, counterclaims, and causes of action between the parties were extinguished, and each side agreed to bear its own legal costs. A dismissal with prejudice is a final adjudication on the merits as a matter of law, meaning the plaintiffs are permanently barred from re-asserting the same claims against Miro on these patents.
The 398-day duration before dismissal — spanning more than thirteen months — is consistent with a case that progressed through at least preliminary stages before the parties reached a resolution. The mutual cost-bearing arrangement and joint filing suggest the outcome was negotiated rather than litigated to a contested ruling. The public record does not disclose any licensing terms, financial consideration, or covenant not to sue, leaving the precise commercial resolution between the parties unknown.

Dismissed with prejudice: what the joint stipulation means for both parties
Rule 41(a)(1)(A)(ii) dismissal with prejudice is final and binding
A joint stipulation under FRCP 41(a)(1)(A)(ii) requires the agreement of all parties and, when filed with prejudice, carries the full legal weight of a final judgment on the merits. The court need not enter a separate order. Crucially, dismissal with prejudice extinguishes the plaintiffs’ right to bring the same patent claims against Miro in any future action — the matter is permanently closed at the claim level.
Permanent bar on re-filingPlaintiffs cannot re-assert these patents against Miro
Web 2.0 Technologies and Pennar Software permanently surrendered their right to pursue US8117644B2 and US6845448B1 against Realtimeboard in any future proceeding. The with-prejudice designation distinguishes this from a tactical withdrawal: the plaintiffs accepted finality. Whether they received any commercial consideration — a lump sum, a licence, or a covenant — is not disclosed in the public record, but the mutual cost-bearing arrangement is consistent with a negotiated exit.
Claims permanently extinguishedMiro secured permanent protection from these specific patent claims
Realtimeboard (Miro) obtained a with-prejudice dismissal, ensuring Web 2.0 Technologies and Pennar Software cannot revive infringement claims on US8117644B2 or US6845448B1 against it. Each party bearing its own fees means Miro did not recover litigation costs, which is typical in negotiated resolutions. The patents themselves remain in force and could theoretically be asserted against other defendants in the collaborative software space.
Protected from re-suit on these patentsOther collaborative platform vendors remain exposed to both patents
The dismissal resolves only the dispute between these specific parties. US8117644B2 and US6845448B1 remain valid and enforceable, and the plaintiffs retain the right to assert them against competing platforms — videoconferencing tools, project-management suites, and other SaaS collaboration products that may overlap with the asserted claims. Companies in the real-time collaboration and digital whiteboard sector should assess their exposure to both patents independently.

Official order — verbatim text
The joint stipulation recites that all claims, counterclaims, and causes of action are dismissed with prejudice under Rule 41(a)(1)(A)(ii), with each party bearing its own costs. The explicit with-prejudice designation is legally significant: it operates as a final adjudication, barring any future suit by the plaintiffs on the same claims against Miro. The absence of any cost or fee award to either side is consistent with a negotiated resolution rather than a contested outcome, though the precise terms of any underlying agreement remain confidential.
US8117644B2 & US6845448B1 — Online Collaboration and Network Access-Control Patents
US8117644B2 (application no. 12/799,945) and US6845448B1 (application no. 09/478,796) together form the asserted portfolio in this action. US6845448B1 carries an earlier application date, suggesting foundational priority in network access or authentication technology predating mainstream SaaS deployment. US8117644B2 reflects a later filing more contemporaneous with the emergence of web 2.0 collaborative applications. Both patents were asserted against Miro’s core product — a multi-user, real-time digital whiteboard — indicating the claims likely touch multi-user session management, access controls, or web-based interaction paradigms.
For companies developing or acquiring real-time collaboration tools, both patents warrant close attention. US6845448B1’s longevity and early priority date suggest broad foundational claims that may read on widely-adopted collaboration architectures. US8117644B2’s more recent filing date positions it to cover contemporary SaaS interaction models. The fact that these patents were asserted against one of the most well-resourced players in the digital whiteboard market — Miro — signals that the patentees view the portfolio as commercially viable for enforcement across the sector.
Should your product team run an FTO against US8117644B2 and US6845448B1?
Any team building a real-time collaborative platform — digital whiteboards, shared canvas tools, agile workflow products, or multi-user SaaS applications — should treat these two patents as active clearance targets. The Miro suit demonstrates that the patentees are willing to pursue well-funded defendants in a favourable forum. If your product enables distributed teams to interact in shared digital workspaces, the claims of both patents are potentially relevant to your architecture.
PatSnap Eureka’s FTO Search Agent allows R&D and IP teams to map the claim scope of US8117644B2 and US6845448B1 against your product’s technical specification in minutes — surfacing relevant prior art, claim charts, and design-around options.

What this case signals for the collaborative software IP landscape
A 398-day lifecycle ending in mutual dismissal suggests these patents carry enough litigation weight to compel negotiation in the SaaS collaboration sector.
Collaborative whiteboard and SaaS platforms face structured patent risk
The assertion of two foundational web-collaboration patents against a market-leading product like Miro signals that IP holders are actively targeting the SaaS whiteboard and remote-work tooling space. Product teams building real-time, multi-user collaboration features should treat freedom-to-operate clearance on both US8117644B2 and US6845448B1 as a baseline diligence requirement.
With-prejudice dismissals do not invalidate the asserted patents
A dismissal with prejudice protects only Miro. The patents survive fully intact and enforceable. Competitors who assumed this litigation resolved the underlying IP risk are exposed: the patentees can file new suits against any other infringing party in the collaborative software space, potentially using the Delaware forum again given its established case history.
Web v Realtimeboard — key questions answered
The case was dismissed with prejudice by joint stipulation on 5 February 2024, after 398 days of litigation. Web 2.0 Technologies and Pennar Software had asserted US8117644B2 and US6845448B1 against Miro’s collaborative whiteboard platform in the Delaware District Court. Each party bears its own costs under the stipulation.
Two patents were asserted: US8117644B2 (application 12/799,945) and US6845448B1 (application 09/478,796). Both relate to online collaboration and network access-control technology and were asserted against Miro’s real-time collaborative whiteboard platform.
Dismissal with prejudice under FRCP 41(a)(1)(A)(ii) means Web 2.0 Technologies and Pennar Software are permanently barred from re-asserting the same claims against Miro. The patents themselves remain valid and enforceable, however, and may still be asserted against other defendants in the collaborative software sector.
The public record does not disclose the precise relationship. However, a co-plaintiff structure of this type is consistent with a licensor-licensee standing arrangement, where a patent owner and an exclusive licensee jointly file to establish standing. This model is common in Delaware patent litigation and suggests the patents may be actively managed for licensing or enforcement purposes.
No. The with-prejudice dismissal protects only Realtimeboard, Inc. (Miro). US8117644B2 and US6845448B1 remain enforceable and the patentees retain the right to pursue infringement claims against other collaborative software and digital whiteboard vendors. Companies in this space should conduct independent FTO clearance against both patents.
