Uniloc 2017 v. Sling TV: Federal Circuit Affirms Unpatentability of Streaming Aggregation Patent
Uniloc 2017, LLC asserted US9721273B2 — a patent covering networked audio-visual content aggregation — against Sling TV, LLC. The Federal Circuit affirmed the lower tribunal’s finding of unpatentability, closing a 657-day appellate proceeding and extinguishing Uniloc’s enforcement position on this patent.
Federal Circuit forecloses Uniloc’s streaming aggregation patent claim
Uniloc 2017, LLC — a patent assertion entity holding a portfolio of technology patents — appealed to the Court of Appeals for the Federal Circuit on 17 November 2022, challenging a finding that US9721273B2 was unpatentable. The patent, filed under application number US14/178064, claims a system and method for aggregating and delivering audio and visual presentations via a computer network, technology directly implicated by Sling TV’s internet-based live television streaming platform.
On 4 September 2024, the Federal Circuit issued an affirmance, upholding the underlying determination of unpatentability. An affirmance at this level means the appellate court identified no reversible legal error in the tribunal’s analysis, leaving the unpatentability finding intact as binding precedent. For Sling TV, the ruling eliminates this specific patent as an enforcement risk. For Uniloc 2017, the avenue to enforce US9721273B2 is now closed absent a successful petition to the Supreme Court.
The 657-day duration suggests the appeal involved substantive briefing rather than a swift procedural resolution, consistent with contested claim construction or eligibility arguments. The basis of termination is recorded as ‘Unpatentable,’ which typically signals the patent was found invalid — most likely under a § 101 subject-matter eligibility or § 103 obviousness framework — though the specific grounds are not detailed in the public case record available here. What drove the Federal Circuit’s affirmance beyond the formal verdict is not fully disclosed in the available data.

Federal Circuit affirms: what the unpatentability ruling means for both parties
Affirmance means the Federal Circuit found no reversible error below
When the Federal Circuit affirms, it is not issuing a new ruling on the merits — it is confirming that the lower tribunal applied the correct legal standard and reached a supportable conclusion. In unpatentability proceedings, this is a high bar for an appellant to overcome. Uniloc’s failure to demonstrate reversible error means the invalidity determination is now final at the circuit level, with no further appeal path except a certiorari petition to the Supreme Court.
No reversible error foundUS9721273B2 is unenforceable — Uniloc’s position is extinguished
The affirmance confirms that US9721273B2 cannot be asserted against Sling TV or, as a practical matter, any other party. A patent found unpatentable by a federal tribunal and affirmed on appeal carries no remaining enforceability. For Uniloc 2017, this eliminates a licensing or litigation asset in the networked content delivery space. The ruling also strengthens defendants in any parallel proceedings involving the same patent.
Patent unenforceableSling TV secures a clean freedom-to-operate win on this patent
With the affirmance, Sling TV has fully neutralised the threat posed by US9721273B2. The company no longer faces infringement exposure under this patent for its audio-visual aggregation and streaming delivery architecture. Sling TV was represented by Baker Botts LLP, whose four-attorney team — including Kurt Pankratz and George Guy III — successfully defended the unpatentability finding through appeal. The ruling provides durable protection for Sling TV’s platform design.
Infringement risk eliminatedAffirmed invalidity raises the bar for similar streaming aggregation claims
For the broader streaming and OTT television sector, the Federal Circuit’s affirmance of unpatentability on a networked audio-visual aggregation patent suggests that broadly-drafted claims in this space remain vulnerable to validity challenge. Competitors and platforms with similar architectures to Sling TV may point to this ruling as persuasive authority when defending against comparable assertions. It also signals that patent examiners and IPR panels may apply heightened scrutiny to continuation or related applications in this technical area.

Official order — verbatim text
The single-word verdict ‘AFFIRMED’ paired with a basis of ‘Unpatentable’ indicates the Federal Circuit conducted a merits review and found the unpatentability determination below to be free from reversible error. At the appellate level, factual findings underlying unpatentability are reviewed for substantial evidence, while legal conclusions — such as § 101 eligibility — are reviewed de novo. The absence of any remand instruction suggests the Federal Circuit agreed with both the legal framework and its application, leaving Uniloc with no remaining avenue at this court level.
US9721273B2 — Networked Audio-Visual Content Aggregation System
US9721273B2, filed under application number US14/178064, claims a system and method for aggregating and providing audio and visual presentations via a computer network. This places the patent squarely in the networked multimedia delivery space — covering the architecture by which content from disparate sources is consolidated and streamed to end users. The patent’s claims are relevant to internet-based television platforms, on-demand video aggregators, and any service that programmatically assembles audio-visual content for network delivery.
The strategic significance of US9721273B2 lies in its potential application to a wide range of OTT and IPTV platforms. Sling TV’s service — which aggregates live TV channels and on-demand content over the internet — was the immediate target, but the claim language could plausibly be read against similar architectures deployed by other streaming platforms. The Federal Circuit’s affirmance of unpatentability significantly diminishes this patent’s value as a licensing or litigation asset, and may influence how related continuation applications in Uniloc’s portfolio are prosecuted or challenged.
Should you run an FTO against US9721273B2?
For product and engineering teams building networked content aggregation platforms — including OTT services, IPTV systems, connected TV applications, and multi-source audio-visual delivery architectures — US9721273B2 has been found unpatentable and affirmed by the Federal Circuit, which substantially reduces direct infringement risk from this specific patent. However, related applications, continuations, or divisionals in the same patent family may carry similar or narrower claims that have not been adjudicated.

What this case signals for the OTT streaming IP landscape
The Federal Circuit’s affirmance closes a key enforcement vector in networked content delivery — and sets a tone for how aggregation patents fare on appeal.
Broadly-drafted aggregation patents are vulnerable at the Federal Circuit
The affirmance of unpatentability in Uniloc v. Sling TV is consistent with a pattern of the Federal Circuit scrutinising software and network-delivery patents that lack narrow, concrete claim limitations. OTT platforms and streaming services facing similar assertions should assess whether the asserted claims share the broad architectural language that proved fatal here.
Uniloc’s portfolio warrants monitoring despite this loss
Uniloc 2017 holds a substantial portfolio of technology patents and has pursued enforcement across multiple sectors. The loss of US9721273B2 does not exhaust related claims. Companies in the content delivery, IPTV, and connected device spaces should monitor Uniloc’s continuation applications and remaining portfolio for claims that overlap with streaming aggregation architectures.
Uniloc v Sling — key questions answered
The Federal Circuit affirmed the unpatentability of US9721273B2 on 4 September 2024. This means the lower tribunal’s finding that the patent was unpatentable was upheld on appeal, and Uniloc 2017’s enforcement position on this patent is extinguished at the circuit level.
US9721273B2 claims a system and method for aggregating and providing audio and visual presentations via a computer network. It was asserted against Sling TV because Sling TV’s internet-based live television platform involves aggregating content from multiple sources and delivering it to subscribers over a network — architecture that Uniloc 2017 contended fell within the patent’s claims.
A basis of termination recorded as ‘Unpatentable’ typically indicates the patent was found invalid — most commonly under 35 U.S.C. § 101 (subject-matter eligibility) or § 103 (obviousness) — at the tribunal level that preceded the Federal Circuit appeal. The Federal Circuit’s affirmance confirms that finding was legally sound. The specific invalidity ground is not fully detailed in the available public docket record.
Following a Federal Circuit affirmance, the losing party’s primary remaining option is to file a petition for a writ of certiorari to the U.S. Supreme Court. However, the Supreme Court accepts a very small fraction of patent cases. As a practical matter, the affirmance effectively closes enforcement of US9721273B2 against Sling TV and makes the patent unenforceable against any party.
The affirmance of unpatentability means US9721273B2 cannot be enforced against any party, not just Sling TV. Other OTT and IPTV platforms with similar networked content aggregation architectures are no longer at risk from this specific patent. The ruling may also be cited as persuasive authority in proceedings involving related Uniloc patents with overlapping claim language.
