Blue Spike v. Universal Music Group: MQA Audio Watermarking Dispute Dismissed With Prejudice
Blue Spike LLC, Wistaria Trading Ltd., and Blue Spike International Ltd. jointly sued Universal Music Group and two affiliates in the Central District of California, asserting four digital watermarking patents against UMG’s MQA-format audio files and encoding software. After 846 days of litigation, the case was dismissed with prejudice by stipulation, with each side bearing its own legal costs.
Four watermarking patents, MQA audio, and a stipulated end with no re-filing rights
Filed on 6 September 2022 in the Central District of California, this infringement action pitted Blue Spike LLC, Wistaria Trading Ltd., and Blue Spike International Ltd. against Universal Music Group, Inc., UMG Manufacturing & Logistics, Inc., and Universal Music Publishing, Inc. The plaintiffs asserted four US patents — US7813506B2, US7664263B2, US7647502B2, and US8265276B2 — all directed at digital signal watermarking and steganographic encoding technology. The accused products were UMG’s computing devices and software encoding digital content in the MQA (Master Quality Authenticated) file format, and the MQA audio files themselves.
The case closed on 30 December 2024, approximately 28 months after filing, via a court-ordered stipulated dismissal with prejudice in its entirety. Dismissal with prejudice is a final adjudication on the merits in terms of preclusive effect: Blue Spike and co-plaintiffs are permanently barred from reasserting these four patents against UMG’s MQA products in any future action. Critically, the order specified that each party shall bear its own attorneys’ fees and costs, indicating no formal finding of exceptional case under 35 U.S.C. § 285 and no fee award to either side.
An 846-day duration before a stipulated exit is consistent with litigation that ran through at least the claim construction phase before a negotiated resolution was reached — though the public record does not disclose whether a settlement agreement underlies the stipulation. The mutual cost-bearing provision, combined with the with-prejudice dismissal, suggests the parties reached a commercially acceptable resolution without the need for a trial or public merits adjudication. What drove UMG’s decision to resolve rather than litigate to judgment — and whether any licensing terms were exchanged — remains undisclosed.
Filing to Voluntary dismissal in 846 days
846 days — roughly 28 months from filing to stipulated dismissal
Dismissed with prejudice by stipulation: what this means for both parties
Stipulated dismissal with prejudice bars all future re-filing
A dismissal with prejudice entered on stipulation of the parties carries full claim-preclusive effect. Unlike a voluntary dismissal without prejudice — which preserves the right to re-file — this order permanently extinguishes Blue Spike’s ability to assert any of the four watermarking patents against UMG’s MQA products. The ‘by stipulation’ framing signals both sides consented, consistent with a negotiated exit rather than a unilateral tactical withdrawal.
Permanent bar on re-filingBlue Spike trades re-filing rights — publicly for undisclosed consideration
By agreeing to a with-prejudice dismissal, the plaintiff group permanently forfeits the right to re-assert these four patents against UMG’s MQA operations. The public record does not disclose whether a confidential licensing payment or cross-licence underlies the stipulation. The mutual cost-bearing provision suggests neither party extracted a clear winner’s advantage in the final order, though the commercial terms — if any — remain sealed.
No public licensing terms disclosedUMG secures permanent protection from these four patents on MQA products
Universal Music Group and its affiliates obtained the strongest available procedural protection short of a court invalidity ruling: a with-prejudice dismissal bars Blue Spike from ever returning to court on the same patents against the same accused MQA products. UMG avoids a public merits finding, preserving flexibility. The own-costs order means UMG absorbs its own litigation spend — suggesting the resolution was commercially preferable to full trial, but not necessarily cost-free.
MQA products effectively clearedMQA watermarking remains untested in court — industry gap persists
The absence of a merits ruling means no judicial analysis of whether MQA encoding infringes Blue Spike’s watermarking patents, and no validity finding on any of the four asserted patents. Other MQA licensees and digital audio platform operators face residual uncertainty: the patents remain in force, and Blue Spike retains the ability to assert them against different defendants. Competitors in high-resolution audio encoding and digital rights management should note the patents were not invalidated.

Official order — verbatim text
The stipulated dismissal order is narrow in scope but maximum in preclusive effect for this defendant-patent pairing. The phrase ‘dismissed with prejudice in its entirety’ confirms all four patent claims against all three UMG entities are permanently extinguished. The explicit ‘each party shall bear their own attorneys’ fees and costs’ provision indicates the court made no exceptional-case finding under 35 U.S.C. § 285. No merits analysis, claim construction ruling, or validity determination appears in the public record.
US7813506B2, US7664263B2, US7647502B2 & US8265276B2 — Digital Audio Watermarking
The four asserted patents — US7813506B2, US7664263B2, US7647502B2, and US8265276B2 — form part of a portfolio associated with Blue Spike LLC and Wistaria Trading Ltd. covering digital watermarking and steganographic signal encoding. These patents relate to methods of embedding imperceptible identification or authentication signals within digital media, a core technology in audio content protection, provenance tracking, and digital rights management. Application dates span the mid-2000s to late 2000s, placing them in the early wave of digital audio format commercialisation.
The strategic importance of this portfolio lies in its breadth across the watermarking signal chain — from encoding methodology to distribution format. MQA (Master Quality Authenticated) is a proprietary audio codec that embeds authentication data within the audio stream itself, making it a natural target for watermarking patent assertions. For streaming platforms, hardware manufacturers, and record labels adopting MQA, the overlap between MQA’s technical architecture and watermarking patent claims represents a recurring enforcement risk. Blue Spike has historically pursued an aggressive, multi-defendant licensing strategy across the audio and media technology sector.
Should you run an FTO against US7813506B2 and the Blue Spike watermarking portfolio?
Any company developing, licensing, or deploying digital audio encoding that embeds authentication or identification signals — including MQA-compatible hardware, streaming infrastructure, or DRM workflows — faces non-trivial exposure to Blue Spike’s watermarking portfolio. The four patents asserted here cover a broad range of signal steganography methods. Because no invalidity ruling was issued in this case, the patents remain presumptively valid and enforceable against new defendants. R&D teams building audio codec pipelines should prioritise FTO analysis before product launch.
PatSnap Eureka’s FTO Search Agent allows IP and product teams to map claim scope across all four Blue Spike watermarking patents against specific technical implementations in minutes. Eureka can surface prior art gaps, identify claim elements most likely to read on MQA-style encoding, and flag related continuation applications that may extend the portfolio’s reach. For in-house teams at audio hardware OEMs, streaming platforms, and broadcast technology companies, this is a high-priority search given Blue Spike’s demonstrated willingness to enforce in federal court.

What this case signals for the digital audio watermarking IP landscape
A with-prejudice exit after 28 months of active litigation carries specific strategic implications for rights holders and technology adopters in the audio encoding sector.
Blue Spike’s watermarking portfolio remains live against other defendants
The dismissal only bars claims against UMG’s specific MQA products. Blue Spike, Wistaria Trading, and Blue Spike International retain full enforcement rights against other parties in the digital audio, streaming, and DRM space. Companies deploying MQA or comparable watermarking technology in audio workflows should assess their own exposure independently.
Stipulated dismissals after 800+ days typically signal negotiated resolution
Voluntary dismissals with prejudice entered this late in a case — past the typical claim construction window — are rarely unilateral. The pattern is consistent with a confidential settlement or licensing arrangement. IP teams monitoring Blue Spike’s enforcement posture should treat this as a resolved licensing event, not an indication of patent weakness or abandonment.
Blue v Universal — key questions answered
The case was dismissed with prejudice in its entirety, by stipulation of the parties. This means Blue Spike LLC, Wistaria Trading Ltd., and Blue Spike International Ltd. are permanently barred from reasserting the four watermarking patents — US7813506B2, US7664263B2, US7647502B2, and US8265276B2 — against UMG and its affiliates in connection with MQA audio products.
Blue Spike asserted four US patents: US7813506B2, US7664263B2, US7647502B2, and US8265276B2. All four relate to digital signal watermarking and steganographic encoding technology. The accused products were UMG’s computing devices and software encoding content in the MQA audio format, and MQA-format digital audio files.
No merits judgment was issued. The case ended via stipulated dismissal with prejudice, which protects UMG from any future re-assertion of these four patents on its MQA products. However, because no court ruled on infringement or validity, there is no public finding that UMG did not infringe or that the patents are invalid.
No. The dismissal order explicitly states that each party shall bear their own attorneys’ fees and costs. This indicates no exceptional-case finding under 35 U.S.C. § 285 was made by the court. The mutual cost-bearing arrangement is consistent with a negotiated resolution rather than a contested ruling.
Yes. The with-prejudice dismissal only extinguishes claims against UMG and its specific MQA products. No invalidity or non-infringement ruling was issued. All four patents — US7813506B2, US7664263B2, US7647502B2, and US8265276B2 — remain presumptively valid and can be asserted against other parties in the audio encoding and digital watermarking space.
