RealTime Data LLC v. Acronis: 6.5-Year Data Compression Patent Dispute Ends With Prejudice
RealTime Data, LLC filed suit against Acronis in the District of Massachusetts in July 2017, asserting four patents covering data compression, encoding, and accelerated storage. After 2,387 days of litigation, the parties jointly stipulated to dismiss all claims with prejudice — each side bearing its own costs.
Six-year data compression IP dispute ends by mutual stipulation
RealTime Data, LLC — a prolific patent assertion entity holding a broad portfolio of data compression and encoding patents — filed this infringement action against Acronis in the District of Massachusetts on July 12, 2017. The complaint asserted four US patents: US9054728B2, US9116908B2, US7415530B2, and US8717204B2, collectively covering data compression systems, data encoding and decoding methods, and accelerated data storage and retrieval. Acronis, a cybersecurity and backup software company, was accused of infringing these patents through its data management and backup products.
The case closed on January 24, 2024, when the parties filed a joint stipulation of dismissal pursuant to Federal Rule of Civil Procedure 41. Under the agreed terms, all claims brought or that could have been brought by RealTime Data were dismissed with prejudice, while Acronis’s counterclaims were dismissed without prejudice. Each party agreed to bear its own litigation costs, attorneys’ fees, and expenses, with no fee-shifting order entered by the court.
The 2,387-day duration — nearly six and a half years — is unusually long for a case resolving short of trial verdict, suggesting extended claim construction proceedings, inter partes review challenges, or protracted settlement negotiations not fully reflected in the public docket. The asymmetric dismissal terms — plaintiff’s claims with prejudice, defendant’s counterclaims without — are consistent with a negotiated resolution that may have involved licensing terms or a covenant not to sue, though no such agreement appears in the public record.

Stipulated dismissal with prejudice under Rule 41 — what it means for each party
Rule 41 Stipulated Dismissal — a negotiated exit, not a court decision
The case closed via a joint stipulation under Federal Rule of Civil Procedure 41, meaning neither party obtained a judicial ruling on the merits. The court did not adjudicate patent validity, claim scope, or infringement. The dismissal was entered upon court approval of the parties’ agreed terms, making the resolution entirely contractual in origin — any underlying deal terms remain private.
No merits ruling enteredClaims dismissed with prejudice; counterclaims dismissed without — a telling asymmetry
RealTime Data’s infringement claims were dismissed with prejudice, permanently barring re-assertion of these specific claims against Acronis. Acronis’s counterclaims — which may have included invalidity or non-infringement declaratory relief — were dismissed without prejudice, preserving Acronis’s ability to revive them if future circumstances warranted. This asymmetry is a common feature of patent settlements and typically signals the plaintiff made a meaningful concession to close the case.
Plaintiff concession signalEach party bears own costs — no fee-shifting, no exceptional case finding
The stipulation explicitly provides that each party bears its own costs, expenses, and attorneys’ fees. Under 35 U.S.C. § 285, courts may award fees to the prevailing party in exceptional cases, but no such finding was made here. The mutual cost-bearing arrangement is consistent with a compromise resolution and avoids any public characterisation of either party’s litigation conduct as improper or unreasonable.
No § 285 fee award2,387 days suggests IPR proceedings or protracted claim construction
Cases dismissed by joint stipulation in the District of Massachusetts typically resolve faster. A 6.5-year duration without reaching trial verdict suggests the parties navigated significant procedural complexity — potentially parallel USPTO inter partes review proceedings that stayed or slowed the district court case, extended claim construction briefing across four patents, or multiple rounds of settlement negotiations before reaching final terms. The public docket does not confirm which factors dominated.

Stipulation of dismissal — official text
The stipulation’s language — ‘all claims that were or could have been brought’ — is a broad claim-preclusion formula designed to maximise finality for Acronis. By encompassing unasserted claims, RealTime Data forecloses any argument that it reserved the right to sue on related patents against the same products. The carve-out preserving Acronis’s counterclaims without prejudice is a standard defensive reservation, ensuring Acronis retains invalidity arguments should successor-in-interest issues arise. No court made any finding on the merits.
US9054728B2 — Data Compression System and Methods
US9054728B2 (application US14/495574) is one of four patents asserted in this action, all drawn from RealTime Data’s extensive data compression and encoding portfolio. The asserted patents collectively protect methods and systems for compressing, encoding, decoding, and accelerating retrieval of data — technology directly relevant to backup software, cloud storage, and data management platforms. US7415530B2 (application US11/553426) is the earliest-filed of the group and predates the AIA, broadening the prior art base available for validity challenges.
RealTime Data’s compression patent portfolio has been deployed against a wide range of technology companies, including storage, networking, and security vendors. For backup software companies like Acronis, these patents represent material IP risk because the claimed methods map readily onto standard compression pipelines used in enterprise and consumer backup products. The breadth of the portfolio — spanning system architecture, encoding algorithms, and retrieval acceleration — means a product clearance analysis must address multiple claim families simultaneously, not just the patents asserted in any single action.
Should your team run an FTO against US9054728B2 and the RealTime Data portfolio?
Any company developing, acquiring, or investing in products that compress, encode, or accelerate retrieval of data — including backup software, cloud storage middleware, database systems, and network appliances — should treat the RealTime Data patent family as a priority FTO target. This case demonstrates that RealTime Data will pursue litigation across multiple defendants for extended periods. Early FTO analysis, combined with an assessment of IPR petition viability, is substantially cheaper than six-plus years of district court litigation.

What this case signals for the data compression and backup software IP landscape
RealTime Data is a repeat asserter. This dismissal resolves one front — but the broader portfolio risk persists for the sector.
RealTime Data’s litigation pattern makes any data compression product a target
RealTime Data has filed dozens of infringement actions across multiple courts asserting overlapping data compression patent families. Companies developing or acquiring backup, storage, or data management software should treat this portfolio as an active enforcement risk — the dismissal here resolves Acronis’s exposure but does not retire the patents from the market.
Dismissal with prejudice caps Acronis’s exposure on these four patents
For Acronis specifically, the with-prejudice dismissal is a clean outcome: RealTime Data cannot reassert these four patents against Acronis’s current or future products. The preserved counterclaims give Acronis residual leverage if the patents are later asserted by a successor or related entity. This structure is a reasonable defensive template for similar defendants negotiating exit from RealTime Data suits.
RealTime v Acronis — key questions answered
RealTime Data LLC sued Acronis for patent infringement in the District of Massachusetts in July 2017, asserting four US patents covering data compression, encoding, and accelerated storage. The case was dismissed with prejudice by joint stipulation under Rule 41 on January 24, 2024, after 2,387 days. Each party bore its own costs and fees. No court ruled on the merits.
RealTime Data asserted four US patents: US9054728B2, US9116908B2, US7415530B2, and US8717204B2. These patents collectively cover data compression systems and methods, encoding and decoding methods, and systems for accelerated data storage and retrieval — technology relevant to Acronis’s backup and data management products.
Dismissal with prejudice means RealTime Data permanently lost the right to assert these specific infringement claims against Acronis in any court. The patents remain valid and enforceable against other defendants, but the stipulation’s language — covering ‘all claims that were or could have been brought’ — bars RealTime Data from asserting related unasserted claims against Acronis on these products as well.
The public record does not provide a definitive explanation. However, a 6.5-year duration for a case that ended without a trial verdict is consistent with parallel USPTO inter partes review proceedings that may have stayed or complicated the district court action, extended claim construction proceedings across four multi-claim patents, or multiple rounds of settlement negotiation. These factors commonly extend patent litigation timelines significantly.
No. The with-prejudice dismissal — covering all claims brought or that could have been brought — prevents RealTime Data from re-asserting these infringement claims against Acronis. Acronis’s counterclaims were preserved without prejudice, giving Acronis residual ability to seek invalidity rulings if a successor entity attempts to reassert related patents in the future.
