USC IP Partnership v. Facebook: Federal Circuit Appeal Voluntarily Dismissed After 590 Days
USC IP Partnership, LP appealed a patentability ruling against Facebook, Inc. at the Court of Appeals for the Federal Circuit, asserting patents US8645300 and US8465300B2. After 590 days, the parties jointly stipulated to voluntary dismissal under Fed. R. App. P. 42(b), with each side bearing its own costs.
Joint voluntary dismissal ends Federal Circuit patent validity appeal
USC IP Partnership, LP filed this appeal at the Court of Appeals for the Federal Circuit on June 28, 2022, challenging a patentability ruling in an invalidity/cancellation action involving Facebook, Inc. The case concerned two patents — US8645300 and US8465300B2 — both relating to a cable installation assembly. The appeal was docketed as Case No. 22-1958 and proceeded through the Federal Circuit, the specialised appellate court for patent matters in the United States.
On February 8, 2024, the parties filed a joint stipulation of voluntary dismissal pursuant to Federal Rule of Appellate Procedure 42(b)(1), and the court ordered the proceeding dismissed accordingly. The order specified that each side shall bear its own costs. The dismissal was filed using the court’s standard joint stipulation form, indicating mutual agreement between USC IP Partnership and Facebook without requiring a formal motion.
The 590-day duration suggests the parties engaged in extended negotiations or parallel proceedings before reaching this resolution. The public record does not disclose the commercial terms, if any, underlying the stipulation. What drove the decision to voluntarily dismiss at the appellate stage — rather than pursue a ruling — remains unknown from publicly available filings, which is consistent with confidential settlement or licensing arrangements that sometimes accompany such dismissals.

What the voluntary dismissal under Fed. R. App. P. 42(b) means for both parties
Fed. R. App. P. 42(b)(1): joint stipulation dismissal explained
Rule 42(b)(1) allows all parties to a Federal Circuit appeal to jointly stipulate to dismissal without requiring court permission or a formal motion. The court’s role is ministerial — once the joint stipulation is filed, dismissal follows as a matter of course. This mechanism is distinct from a unilateral voluntary dismissal, which may require a motion under Rule 42(b)(2)–(3). The joint nature of this filing signals mutual agreement between USC IP Partnership and Facebook.
Mutual consent dismissalWith or without prejudice? The public record is silent
A dismissal ‘with prejudice’ permanently bars the dismissing party from relitigating the same claims; a dismissal ‘without prejudice’ preserves that right. The court’s order in this case states only that the proceeding is ‘dismissed’ under Rule 42(b) — it does not specify either qualifier. The public record is therefore silent on this point. Practitioners should treat the prejudice status as indeterminate without access to any underlying agreement between the parties.
Prejudice status: not specifiedEach side bears its own costs — no prevailing party
The court’s order expressly provides that each side shall bear its own costs. At the Federal Circuit, appellate costs typically include filing fees and reproduction of the appendix. The mutual cost-bearing arrangement is consistent with a negotiated resolution and avoids any implicit acknowledgment of a prevailing party. This is a commercially neutral cost outcome that neither penalises the appellant nor rewards the appellee.
No cost awardUnderlying validity of US8645300 and US8465300B2 remains unresolved by appeal
Because the appeal was dismissed before the Federal Circuit issued any substantive ruling, the court rendered no opinion on the merits of the patentability challenge to US8645300 or US8465300B2. The validity determination from the lower tribunal — which prompted the appeal — therefore stands as the last substantive ruling on record. Third parties should consult the underlying IPR or district court record to assess the current validity posture of these patents.

Stipulation of dismissal — official text
The court’s dismissal order is narrow in scope: it confirms the proceeding is terminated under Rule 42(b) and allocates costs equally, but issues no opinion on the merits of the patentability challenge. For USC IP Partnership, the dismissal closes the appellate chapter without a public loss; for Facebook, it avoids a potentially precedential validity ruling. The order’s silence on prejudice is legally significant — it means the enforceability of the underlying patents and the rights of either party to pursue related claims in future proceedings cannot be determined from this document alone.
US8645300 & US8465300B2 — cable installation assembly patents
US8645300 and US8465300B2 are related patents in the cable installation assembly space, originating from application numbers US13/186787 and US13/232914 respectively. The related application numbers suggest these patents share a common inventive lineage — possibly a continuation or divisional relationship — covering aspects of cable installation hardware or methodology. Their assertion against a major technology platform in a patentability proceeding indicates the claims were framed as broadly applicable beyond traditional cable infrastructure contexts.
The assertion of cable installation assembly patents against Facebook is strategically notable: it suggests USC IP Partnership interpreted the claims as covering digital infrastructure, data centre cabling, or connectivity systems relevant to large-scale platform operators. Whether that claim scope interpretation survived the validity challenge is unresolved by the Federal Circuit record. Competitors in data centre construction, telecommunications infrastructure, and enterprise networking should monitor the citation history of both patents for downstream enforcement activity.
Should your team run an FTO against US8645300 and US8465300B2?
Any company involved in cable installation systems, data centre infrastructure, or large-scale connectivity hardware should consider whether US8645300 and US8465300B2 present freedom-to-operate risk. The fact that these patents were asserted against a major platform operator — and that the appeal was resolved without a merits ruling — means their enforceability and claim scope remain live questions. Product teams designing or procuring cable assembly systems cannot rely on this case’s outcome as a clearance signal.
PatSnap Eureka’s FTO Search Agent can map the claim language of US8645300 and US8465300B2 against your product specifications, flag related family members, and surface prior art that informed the original invalidity challenge.

What this case signals for the cable technology IP landscape
A Federal Circuit appeal dropped by joint stipulation after 590 days raises pointed questions about patent enforceability and licensing strategy in this space.
Federal Circuit dismissals without a ruling leave validity in a grey zone
When an appeal is voluntarily dismissed before the Federal Circuit rules on validity, the last substantive decision on patentability stands unchallenged on appeal. For competitors and licensees, this creates uncertainty: the patents may be enforceable, invalid, or subject to undisclosed licensing terms. Any product team in the cable installation space should treat these patents as live risk until their status is independently confirmed.
Joint cost-bearing is consistent with a negotiated resolution
The ‘each side bears own costs’ order, combined with a joint — not unilateral — stipulation, suggests the parties reached some form of accommodation. While no financial terms are disclosed, this pattern is commonly observed when a licence, covenant not to sue, or other commercial arrangement resolves the underlying dispute before a court ruling is needed. The absence of a prevailing party declaration reinforces this inference.
USC v Facebook — key questions answered
The case was voluntarily dismissed by joint stipulation under Fed. R. App. P. 42(b)(1) on February 8, 2024. USC IP Partnership had appealed a patentability ruling concerning patents US8645300 and US8465300B2 against Facebook. The court ordered each side to bear its own costs and issued no ruling on the merits of the validity challenge.
Two patents were involved: US8645300 (application number US13/186787) and US8465300B2 (application number US13/232914). Both relate to cable installation assembly technology. The validity of these patents was challenged in an invalidity/cancellation action, which gave rise to the Federal Circuit appeal.
The court’s order does not specify whether the dismissal was with or without prejudice. It states only that the proceeding is ‘dismissed’ under Rule 42(b). The public record is silent on this distinction. The prejudice status would typically be governed by any underlying agreement between the parties, which has not been publicly disclosed.
Rule 42(b)(1) permits all parties to jointly stipulate to dismiss a Federal Circuit appeal without court permission or a formal motion. Once filed, the court issues a dismissal order as a matter of course. No merits ruling is issued, and the outcome of the lower tribunal remains the last substantive decision on record. It is commonly used when parties reach a settlement or licensing agreement during the appellate process.
