Vivion v. ADT & Alarm.com: Federal Circuit Affirms Patent Unpatentable
Vivion, Inc. asserted US7956739B2, covering monitoring and entry system presence services, against security industry defendants ADT and Alarm.com. The Federal Circuit affirmed the patent’s unpatentability in a Rule 36 judgment, closing the appeal after 539 days without a written opinion.
Federal Circuit ends Vivion’s patent claim with a silent Rule 36 affirmance
Vivion, Inc. filed appeal No. 23-1787 at the Court of Appeals for the Federal Circuit on 25 April 2023, challenging an earlier determination that US7956739B2 — directed to monitoring and entry system presence services — was unpatentable. The defendants, ADT and Alarm.com, are major commercial players in the smart home security and remote monitoring sector, represented by Cravath, Swaine & Moore. Vivion was represented by Maschoff Brennan PLLC.
On 15 October 2024, the Federal Circuit issued a Rule 36 judgment — a single-line affirmance with no written opinion — upholding the finding of unpatentability. This means the lower tribunal’s invalidity or cancellation determination stands in full. For ADT and Alarm.com, the ruling eliminates the patent as a litigation or licensing threat. For Vivion, it extinguishes the asserted patent right entirely at this appellate level.
The 539-day duration suggests the court considered the matter carefully before issuing a Rule 36 affirmance, though the absence of a written opinion leaves the precise legal reasoning opaque. Rule 36 judgments are typically reserved for cases where the Federal Circuit finds no substantial question warranting elaboration, consistent with a straightforward application of patentability doctrine. What arguments Vivion raised on appeal — and why they failed to generate a written response — cannot be confirmed from the public docket alone.

Federal Circuit affirms: what the Rule 36 ruling means for both parties
Rule 36 affirmance: the Federal Circuit’s silent ‘no error’ signal
A Rule 36 judgment means the Federal Circuit affirmed the lower decision without a written opinion, finding no reversible error requiring elaboration. It is not a default or procedural dismissal — the court reviewed the merits and determined the unpatentability finding below was correct. Crucially, it sets no binding precedent, but the outcome for the parties is final and fully binding.
Affirmed without opinionUS7956739B2 is unpatentable — Vivion’s appellate path is closed
The Federal Circuit’s affirmance confirms that US7956739B2 does not survive patentability scrutiny. Vivion cannot enforce or license this patent against ADT, Alarm.com, or — as a practical matter — any third party relying on the same invalidity grounds. Further appeal to the Supreme Court is theoretically possible via certiorari, but the Court rarely grants cert on patent validity questions decided under Rule 36.
Patent extinguishedADT and Alarm.com secure full clearance on this patent
For ADT and Alarm.com, the ruling eliminates US7956739B2 as any future enforcement or licensing risk. Their monitoring and entry system presence services are no longer encumbered by this patent. The engagement of Cravath, Swaine & Moore — a top-tier litigation firm — signals the defendants treated this as a commercially significant dispute, and the clean Rule 36 outcome vindicates that investment.
Full defendant clearanceSecurity monitoring sector: one fewer patent overhang on presence services
The cancellation of a patent covering monitoring and entry system presence services reduces assertion risk for the broader smart home and commercial security industry. Competitors operating in the remote monitoring, entry detection, and presence-sensing space can now operate without exposure to this specific patent. However, the Rule 36 format means no claim construction or validity reasoning was published — limiting its direct use as precedent in parallel disputes.

Official order — verbatim text
The verdict — ‘AFFIRMED. See Fed. Cir. R. 36.’ — is the Federal Circuit’s most terse form of merits disposition. It confirms the court applied appellate review standards (typically substantial evidence for factual findings, de novo for legal conclusions on patentability) and found no basis to disturb the lower tribunal’s unpatentability determination. No written reasoning is published, which forecloses citation as precedent but does not diminish the binding force of the outcome for Vivion, ADT, and Alarm.com.
US7956739B2 — Monitoring and entry system presence service
US7956739B2, filed under application number US12/483306, covers monitoring and entry system presence services — technology relevant to detecting and communicating occupancy or access events within secured environments. This patent family sits at the intersection of networked security systems, remote monitoring infrastructure, and presence-sensing logic, a space that has seen significant commercial and litigation activity as smart home and enterprise security platforms have scaled.
The patent’s strategic significance lies in its potential reach across monitoring platforms used by major security providers. ADT and Alarm.com’s decision to contest patentability through what appears to be a post-grant proceeding — rather than seeking a licensing arrangement — reflects the commercial sensitivity of presence-service claims in a market where recurring monitoring revenues depend on unencumbered platform operation. The Federal Circuit’s affirmance of unpatentability removes this specific risk vector for the sector.
Should you run an FTO against US7956739B2?
Any company developing or deploying monitoring and entry system presence services — including smart home security platforms, commercial access control systems, or IoT-based occupancy detection products — should assess whether related patents in the same priority family remain active. US7956739B2 itself is now confirmed unpatentable, but continuation or divisional applications sharing the US12/483306 priority chain may carry overlapping claims that have not yet been adjudicated.
PatSnap Eureka’s FTO Search Agent can rapidly map the full priority family around US12/483306, identify any surviving continuations, and flag claim language that overlaps with your product architecture. For R&D and product teams operating in the monitoring and presence-detection space, this kind of proactive clearance search is materially lower cost than defending a Federal Circuit appeal — as this case illustrates.

What this case signals for the smart home security IP landscape
A Federal Circuit Rule 36 affirmance of unpatentability sends a clear message about the durability of presence-service monitoring patents in post-grant proceedings.
Rule 36 outcomes are final — but leave the legal reasoning invisible
Patent holders and defendants alike should understand that a Rule 36 affirmance closes the case with binding force but generates no citable reasoning. Companies monitoring the monitoring and entry system sector cannot extract claim construction guidance from this ruling — they must rely on the lower tribunal record instead.
Presence-service patents face heightened invalidity scrutiny at the PTAB and Federal Circuit
The unpatentability finding in this case, affirmed without dissent or written opinion, suggests the claims of US7956739B2 were not close calls. Companies holding or acquiring patents in the remote monitoring and presence-detection space should proactively audit claim strength against prior art before assertion.
Vivion v ADT — key questions answered
The Federal Circuit affirmed the unpatentability of US7956739B2 in a Rule 36 judgment issued 15 October 2024. The court found no reversible error in the lower tribunal’s invalidity or cancellation determination, closing the appeal without a written opinion. ADT and Alarm.com are no longer exposed to this patent.
A Rule 36 judgment is a one-line affirmance issued without a written opinion. It means the Federal Circuit reviewed the record and found no substantial question warranting elaboration — the lower decision stands in full. For Vivion, it is a binding, final loss. The ruling sets no citable precedent but is fully enforceable between the parties.
US7956739B2, filed as US12/483306, covers monitoring and entry system presence services — technology that detects and communicates occupancy or access events in secured environments. This is directly relevant to smart home security platforms and commercial monitoring services offered by companies like ADT and Alarm.com, making it commercially sensitive in a high-revenue recurring-services market.
No. The Federal Circuit’s affirmance of unpatentability means US7956739B2 cannot be enforced. Vivion’s only remaining option is a petition for certiorari to the Supreme Court, which is rarely granted in patent validity cases. As a practical matter, this patent is extinguished as an enforcement or licensing tool.
The public record for this case addresses only US7956739B2. However, companies in the monitoring and entry system sector should investigate whether continuation or divisional applications filed off priority application US12/483306 remain pending or granted. PatSnap Eureka can map the full priority family to identify any surviving related claims.
