Data Resonance v. Backblaze: Dismissed With Prejudice in 35 Days
Data Resonance, LLC filed a patent infringement action against cloud storage provider Backblaze, Inc. in the District of Delaware asserting US6934714B2, covering methods for identifying and maintaining families of data records. The case ended in a stipulated dismissal with prejudice in just 35 days — an unusually swift resolution that forecloses any refiling of the same claims.
A 35-Day Stipulated End to a Delaware Data Patent Dispute
Data Resonance, LLC filed suit against Backblaze, Inc. on December 6, 2024, in the District of Delaware before Judge Jennifer L. Hall, asserting infringement of US6934714B2. The patent covers a method and system for identification and maintenance of families of data records — technology relevant to cloud storage and data management infrastructure of the kind Backblaze operates at scale.
The case closed on January 10, 2025, just 35 days after filing. The parties filed a joint stipulation under Federal Rule of Civil Procedure 41(a)(1)(A)(ii), dismissing all claims against Backblaze with prejudice and all of Backblaze’s counterclaims against Data Resonance without prejudice. The asymmetric dismissal terms are notable: Data Resonance permanently surrenders its infringement claims against Backblaze, while Backblaze retains the ability to refile its counterclaims.
A resolution in 35 days — before any substantive motion practice or claim construction — strongly suggests the parties reached a private settlement agreement, though the public record contains no disclosed financial terms. The with-prejudice dismissal of plaintiff’s claims is a meaningful concession, effectively acting as a litigation bar against Data Resonance reasserting these specific patent claims against Backblaze. What drove the rapid resolution and whether any licensing arrangement was reached remain unknown from the docket.
Filing to Dismissed with Prejudice in 35 days
35 days — well below the median district court patent case lifecycle of 2–3 years
Dismissed with prejudice: what the stipulation means for both parties
Rule 41(a)(1)(A)(ii): the parties ended this themselves
A stipulated dismissal under Fed. R. Civ. P. 41(a)(1)(A)(ii) requires both parties to sign, giving each side contractual control over the exit terms. No court merits ruling was issued. The with-prejudice designation on plaintiff’s claims carries the same legal weight as a final judgment — Data Resonance cannot refile the same infringement claims against Backblaze in any federal court.
No merits adjudicationData Resonance permanently bars itself from suing Backblaze on this patent
A with-prejudice dismissal of all claims is a significant concession from the plaintiff. Data Resonance loses the right to assert US6934714B2 against Backblaze in the future, regardless of any new infringement theory. This outcome is consistent with either a settlement payment or a recognition that the litigation posed unacceptable risk to the patent itself. The public record does not disclose which factor drove the decision.
Claims extinguishedBackblaze escapes liability — but retains live counterclaims
Backblaze’s counterclaims against Data Resonance were dismissed without prejudice, meaning Backblaze preserves the option to refile them. This asymmetry suggests Backblaze negotiated from a position of relative strength. Counterclaims in patent cases frequently include invalidity or unenforceability challenges, and retaining them without prejudice gives Backblaze ongoing leverage if Data Resonance asserts the patent elsewhere.
Counterclaims preservedOther cloud storage players should monitor this patent’s litigation activity
US6934714B2 remains in force and was not invalidated in this proceeding. Data Resonance retains the right to assert it against third parties. The 35-day resolution and with-prejudice dismissal suggest either a licensing deal or a credible invalidity threat from Backblaze. Companies operating data deduplication, backup, or record-family management systems should assess their exposure to this patent before a demand letter arrives.

Official order — verbatim text
The stipulation language — dismissing plaintiff’s claims ‘WITH PREJUDICE’ and counterclaims ‘WITHOUT PREJUDICE’ — reflects a deliberate, negotiated asymmetry. The with-prejudice designation on Data Resonance’s claims operates as a final adjudication on the merits for res judicata purposes, permanently barring re-assertion against Backblaze. The without-prejudice treatment of Backblaze’s counterclaims suggests those claims — likely invalidity or non-infringement defences — were preserved as negotiating leverage rather than litigated to conclusion.
US6934714B2 — Method and system for families of data records
US6934714B2, filed under application number US10/091378, covers a method and system for the identification and maintenance of families of data records. The patent addresses the technical problem of grouping, tracking, and managing related data records within large-scale storage systems — a foundational capability for backup, deduplication, and cloud data management platforms. Its priority date places it among earlier-generation data infrastructure patents that have gained renewed relevance as cloud storage scaled.
For the cloud storage sector, US6934714B2 represents a category of legacy data management IP that can be asserted against modern infrastructure if claim mapping to current architectures is plausible. Backblaze operates petabyte-scale cloud storage and backup services where record-family identification and maintenance are core system functions. The patent’s survival in this case — without invalidation — means it remains a potential enforcement vector against other storage providers, SaaS backup platforms, and enterprise data management vendors operating similar architectures.
Should your data management platform run an FTO against US6934714B2?
Any company building or operating cloud backup services, data deduplication engines, record indexing systems, or storage management platforms should assess freedom-to-operate against US6934714B2. The patent was actively enforced in 2024 and emerged from this litigation without validity adjudication. If your product identifies, groups, or maintains families of data records — whether in backup, archival, or analytics contexts — a targeted FTO analysis is warranted before scaling deployment or entering new markets.
PatSnap Eureka’s FTO Search Agent can map the claims of US6934714B2 against your product’s technical architecture, surface prior art that may support invalidity arguments, and identify whether any claim limitations are clearly avoided by your implementation. For in-house IP teams and R&D leads at cloud storage or data management companies, running this analysis now is significantly less costly than responding to a demand letter later.

What this case signals for the cloud storage and data management IP landscape
A 35-day stipulated dismissal with asymmetric terms rarely happens without a backstory. Here is what practitioners should read into the record.
Speed of resolution is a signal, not just a statistic
Patent cases settled before any court ruling typically reflect one of two dynamics: a licensing payment to make the case go away quickly, or a credible invalidity defence that made continued litigation unattractive for the plaintiff. At 35 days, no claim construction or Rule 12 briefing had occurred, suggesting the outcome was driven by negotiation rather than litigation risk from court proceedings.
The asymmetric dismissal terms deserve careful attention
Plaintiff’s claims dismissed with prejudice; defendant’s counterclaims dismissed without prejudice. This structure is consistent with Backblaze having filed — or credibly threatened — invalidity counterclaims that gave Data Resonance reason to settle quickly. Patent holders should anticipate that well-resourced defendants like Backblaze, represented by Fish & Richardson, will mount early and aggressive invalidity challenges.
Data v Backblaze — key questions answered
Data Resonance, LLC filed a patent infringement action against Backblaze, Inc. in the District of Delaware on December 6, 2024, asserting US6934714B2. The case was dismissed on January 10, 2025 — 35 days later — via a joint stipulation under Rule 41(a)(1)(A)(ii). All claims against Backblaze were dismissed with prejudice; Backblaze’s counterclaims were dismissed without prejudice.
A dismissal with prejudice operates as a final judgment on the merits. Data Resonance permanently loses the right to assert US6934714B2 against Backblaze in any future proceeding. The company retains the right to enforce the patent against unrelated third parties, but the claims against Backblaze are extinguished by operation of law.
The asymmetric dismissal terms suggest Backblaze negotiated to preserve its counterclaims — likely invalidity or unenforceability challenges — as leverage. Dismissal without prejudice allows Backblaze to refile those claims if Data Resonance later asserts the patent against it again or if the preserved claims become strategically relevant. This structure is common where a defendant wants a clean exit but retains defensive optionality.
Yes. US6934714B2 was not adjudicated, invalidated, or cancelled in this proceeding. No court ruling on validity or infringement was issued. The patent remains in force and Data Resonance retains the right to assert it against other parties. Companies in the cloud storage and data management sector should treat the patent as an active enforcement risk.
US6934714B2 covers a method and system for the identification and maintenance of families of data records — a technical approach to grouping, tracking, and managing related data records within storage systems. The technology has potential applicability to cloud backup, data deduplication, record indexing, and storage management platforms, making it relevant to modern cloud infrastructure providers like Backblaze.
