Hybir v. Veeam Software: Federal Circuit Affirms Backup Patent Unpatentable
Hybir, Inc. appealed to the U.S. Court of Appeals for the Federal Circuit after its patent on a group-based incremental computer file backup system (US8051043B2) was found unpatentable. The Federal Circuit affirmed the lower tribunal’s invalidity finding in a case that ran 581 days from filing to close.
Federal Circuit closes the door on Hybir’s incremental backup patent
Hybir, Inc. brought this appeal before the U.S. Court of Appeals for the Federal Circuit on 22 July 2022, challenging a prior determination that US8051043B2 — a patent covering a group-based complete and incremental computer file backup system, process, and apparatus — was unpatentable. Veeam Software Corporation, a major player in the data protection and backup software market, was the opposing party defending the invalidity finding.
The Federal Circuit issued its decision on 23 February 2024, affirming the unpatentability of US8051043B2. An affirmance in an invalidity/cancellation action means the court agreed that the patent lacked the requisite patentability criteria — most commonly novelty or non-obviousness. With this ruling, Hybir’s patent protection over the asserted backup technology is effectively extinguished, removing any basis for future enforcement of this patent against Veeam or any other party.
The 581-day duration is consistent with a typical Federal Circuit patent appeal, which commonly runs 18–24 months. The case proceeded through to a substantive affirmance rather than settling, suggesting the patentability dispute was not amenable to commercial resolution between the parties. The public record does not reveal the specific prior art or claim construction arguments that drove the outcome, nor whether Hybir holds related continuation patents that may still be enforceable.

Federal Circuit affirms US8051043B2 unpatentable — what this means
What ‘Affirmed — Unpatentable’ means in practice
An affirmance of an unpatentability finding means the Federal Circuit agreed with the tribunal below that US8051043B2 failed to meet the legal standards for a valid patent. This is a final appellate ruling. The patent is no longer enforceable, and Hybir cannot use this specific patent to assert infringement against Veeam or any third party going forward. The decision has immediate commercial consequence for anyone who was monitoring this patent as a litigation risk.
Patent extinguishedInvalidity/cancellation: the mechanism behind the ruling
The verdict cause is listed as an invalidity/cancellation action on patentability grounds. This category typically encompasses challenges under 35 U.S.C. §§ 102 (novelty) or 103 (non-obviousness), often raised via inter partes review before the USPTO’s Patent Trial and Appeal Board, with Federal Circuit appeal following. The public record does not specify which prior art or statutory ground prevailed, but the affirmance suggests the challenge was substantively compelling.
Patentability challengeVeeam’s freedom to operate is now clearer
With US8051043B2 invalidated and affirmed as unpatentable, Veeam Software can operate its backup and data protection products without the overhang of this specific patent. For competitors and new entrants in the incremental backup space, this ruling removes one patent from the enforcement landscape. Companies that were previously exposed to licensing demands or litigation threats based on this patent should update their FTO assessments accordingly.
FTO impact — backup sectorHybir’s enforcement strategy may hinge on related patents
The invalidation of US8051043B2 does not necessarily end Hybir’s IP position entirely. Patent families frequently include continuation or divisional applications that may cover similar subject matter under different claim structures. Any party operating in the group-based or incremental backup technology space should audit Hybir’s broader patent portfolio for related applications before concluding the competitive risk has been fully resolved.

Stipulation of dismissal — official text
The single-word verdict ‘AFFIRMED’ in an invalidity/cancellation action carries decisive weight. It confirms the Federal Circuit found no reversible error in the lower tribunal’s determination that US8051043B2 fails patentability standards. For Hybir, this forecloses further appellate options on this patent. For Veeam and the broader backup software market, the affirmance provides firm ground: this patent cannot be revived for enforcement purposes, and any licensing demands premised on it are now legally unsupportable.
US8051043B2 — Group-Based Incremental Computer File Backup System
US8051043B2 (Application No. 11/744741) protects a group-based system, process, and apparatus for performing both complete and incremental computer file backups. The patent’s core innovation, as asserted, relates to organizing backup operations by logical groups of files rather than treating each backup target individually — an approach with implications for backup efficiency, deduplication, and storage optimization. The patent falls within the data storage and backup management technology domain.
Group-based and incremental backup architectures sit at the heart of enterprise data protection products marketed by vendors including Veeam, Commvault, Veritas, and others. A valid, enforceable patent in this space would carry meaningful licensing leverage over a multi-billion dollar market. The Federal Circuit’s affirmance of unpatentability removes this specific asset from the enforcement landscape, but it also signals that prior art in the incremental backup space is dense — a warning to patent drafters seeking to protect novel backup architectures.
Should you run an FTO check against US8051043B2?
For product teams building or marketing group-based, incremental, or deduplicated backup systems, US8051043B2 has been affirmed unpatentable and is no longer an active infringement risk. However, any FTO review relying solely on this patent’s status is incomplete. Hybir’s patent family may include related applications with surviving claims. If your product operates in the backup software, disaster recovery, or data protection space, a full FTO should map Hybir’s entire filing portfolio, not just this single asset.
PatSnap Eureka’s FTO Search Agent can cross-reference US8051043B2’s claim language against active patents in the backup and storage management space, identify related continuations by Hybir, and flag overlapping claim scope in live patents held by other rights holders. Continuous claim monitoring in Eureka ensures that if any related application publishes or issues, your team receives an immediate alert — before a new enforcement action materialises.

What this case signals for the data backup IP landscape
A Federal Circuit affirmance of invalidity is a high-bar outcome — it shapes enforcement risk and competitive freedom across the backup software sector.
Incremental backup patent claims face sustained scrutiny at the PTAB and Federal Circuit
The affirmance of unpatentability in this case is consistent with a broader pattern of aggressive invalidity challenges against software and data management patents. Companies in the backup, recovery, and data protection space should treat Federal Circuit affirmances as a signal to re-examine the claim quality and prior art exposure of their own patent portfolios before asserting or licensing those assets.
Veeam’s successful defense sets a precedent for invalidating group-backup architectures
Veeam’s representation by Sterne, Kessler, Goldstein & Fox — a firm with deep PTAB and Federal Circuit experience — suggests a well-resourced, technically grounded invalidity strategy. Competitors facing similar patent assertions from NPEs or smaller patent holders in the backup technology space can treat this outcome as a strategic reference point for mounting or evaluating comparable defenses.
Hybir v Veeam — key questions answered
The Federal Circuit affirmed the unpatentability of US8051043B2, Hybir’s patent covering a group-based complete and incremental computer file backup system. The case closed on 23 February 2024, 581 days after filing. The affirmance means the patent is extinguished and unenforceable.
Hybir asserted US8051043B2 (Application No. 11/744741), which covers a group-based complete and incremental computer file backup system, process, and apparatus. The patent relates to organizing backup operations by logical file groups, relevant to enterprise data protection and storage efficiency technologies.
An affirmance of unpatentability at the Federal Circuit is a final appellate determination that the patent failed to meet statutory requirements — typically novelty or non-obviousness. The patent cannot be enforced against any party. The ruling effectively ends the patent’s commercial life as an enforcement or licensing asset.
The verdict cause is recorded as an invalidity/cancellation action on patentability grounds, and the appeal path to the Federal Circuit is consistent with a PTAB inter partes review proceeding. However, the public case record does not expressly confirm IPR origin, and this characterisation should be treated as a reasonable inference rather than a confirmed fact.
Not necessarily. The invalidation of US8051043B2 removes this specific patent from the enforcement landscape. However, patent families commonly include continuation or divisional applications with related claim scope. Companies in the backup and data protection space should conduct a full portfolio review of Hybir’s filings to assess whether residual patent risk remains from related applications before concluding exposure is eliminated.
