Jenam Tech v. Google: Federal Circuit Appeal Dismissed in 334 Days
Jenam Tech, LLC challenged Google, LLC at the Court of Appeals for the Federal Circuit over US10306026B1, a patent covering methods for detecting idle TCP connections. The appeal, rooted in a patentability invalidity dispute, was dismissed by agreement under Fed. R. App. P. 42(b) with each side bearing its own costs — resolved in under a year.
Federal Circuit patentability appeal ends by mutual agreement
Jenam Tech, LLC filed this appeal at the Court of Appeals for the Federal Circuit on February 9, 2023, challenging a patentability determination involving US10306026B1 — a patent directed at methods, systems, and computer program products for sharing information to detect idle TCP connections. The respondent was Google, LLC, represented by Paul Hastings, LLP. The underlying dispute was characterised as an invalidity or cancellation action, suggesting the patent’s validity had been contested at a lower tribunal, likely the USPTO’s Patent Trial and Appeal Board, before reaching the Federal Circuit.
The appeal concluded on January 9, 2024 — 334 days after filing — when the parties reached an agreement to dismiss the proceeding under Federal Rule of Appellate Procedure 42(b). The dismissal order specifies that each side shall bear its own costs, which is the default position under Rule 42(b) when parties agree to dismiss. No merits ruling was issued by the Federal Circuit, meaning the court’s substantive view on the patentability questions raised in the appeal remains unknown from the public record.
A 334-day resolution at the Federal Circuit is relatively swift for a contested patentability appeal, suggesting the parties may have reached a commercial or licensing arrangement that made continued litigation uneconomical. The mutual cost-bearing arrangement is consistent with a negotiated exit rather than a capitulation by either side. Critically, because dismissal was entered without a merits decision, the underlying validity questions about US10306026B1 — and their implications for the broader TCP connection management patent landscape — were not publicly resolved.

Appeal dismissed by agreement — no merits ruling, costs split
Fed. R. App. P. 42(b): Voluntary Dismissal on Appeal
Rule 42(b) allows parties to a federal appellate proceeding to jointly agree to dismiss the appeal at any time. Unlike a dismissal ordered by the court on substantive grounds, a 42(b) dismissal is procedural and party-driven. It does not constitute a ruling on the merits of either the patentability arguments or any infringement claims. The Federal Circuit simply closes the proceeding on the basis of the parties’ agreement, without endorsing either party’s legal position.
Procedural exit — no merits adjudicationEach Side Bears Own Costs — What This Signals
Under Rule 42(b)(2), when parties agree to dismiss, the default is that each side bears its own costs unless the parties stipulate otherwise. The order here follows that default. This neutral cost allocation neither signals a win nor a loss for either party. It is broadly consistent with a negotiated resolution — whether a licensing deal, covenant not to sue, or simply a mutual decision to cease proceedings — where neither side conceded enough to accept a cost burden.
Neutral cost split — Rule 42(b)(2) defaultInvalidity Challenge: What Was at Stake for US10306026B1
The verdict cause is classified as an invalidity/cancellation action, consistent with a Patent Trial and Appeal Board (PTAB) inter partes review or post-grant proceeding that Jenam Tech then appealed to the Federal Circuit. Had the appeal proceeded to a merits decision, the Federal Circuit could have affirmed cancellation of the patent’s claims, reversed and reinstated them, or remanded. The agreement to dismiss leaves the patent’s legal status as determined by the lower tribunal in place, without Federal Circuit endorsement or reversal.
Patent validity status determined belowEarly Exit Suggests Negotiated Resolution Between Parties
Resolving a Federal Circuit patentability appeal in approximately 11 months, before full merits briefing typically concludes, suggests the parties arrived at a commercial understanding. For Jenam Tech, continuing the appeal carried the risk of an adverse Federal Circuit ruling that could further weaken or extinguish the patent. For Google, a negotiated exit may have been preferable to the cost and uncertainty of appellate proceedings. The mutual cost-bearing structure is consistent with a balanced negotiation outcome rather than a one-sided settlement.

Stipulation of dismissal — official text
The dismissal order is brief and procedural: the proceeding is dismissed under Fed. R. App. P. 42(b) by agreement of the parties, with each side bearing its own costs. This phrasing confirms the exit was consensual and non-adversarial — no party was ordered to bear the other’s costs, and no substantive ruling on patentability was issued. For Jenam Tech, the dismissal leaves the lower tribunal’s patentability determination in place without Federal Circuit reversal. For Google, it closes the appellate record without creating adverse precedent.
US10306026B1 — Idle TCP Connection Detection Methods
US10306026B1 protects methods, systems, and computer program products for sharing information used to detect idle TCP (Transmission Control Protocol) connections. TCP connection management is a foundational layer of internet and enterprise networking — idle connection detection is relevant to server efficiency, resource allocation, load balancing, and security monitoring. The patent, held by Jenam Tech, LLC, was the subject of a patentability invalidity challenge that progressed through PTAB before reaching the Federal Circuit on appeal in February 2023.
The strategic value of a patent in this space lies in the breadth of potential application: TCP session management is embedded in cloud platforms, CDN infrastructure, enterprise network appliances, web servers, and virtually any system managing persistent connections at scale. A valid, enforceable claim covering idle TCP detection methods could implicate a wide range of products. The fact that Google — whose infrastructure depends heavily on TCP connection management at massive scale — was the respondent underscores the commercial stakes attached to this patent’s validity.
Should your product team run an FTO against US10306026B1?
Any organisation developing or shipping products that manage TCP connections — including cloud load balancers, network proxies, enterprise firewalls, session-aware APIs, or web server infrastructure — should consider whether US10306026B1 poses a freedom-to-operate risk. Because the Federal Circuit dismissed this appeal without issuing a merits ruling, the patent’s validity status as determined by PTAB remains in place and was not overturned. That means the patent is a live consideration for FTO purposes until its legal status is definitively resolved or the patent expires.

What this case signals for the networking software IP landscape
A quietly resolved Federal Circuit appeal over TCP connection technology carries practical signals for IP teams in cloud, networking, and enterprise software.
PTAB validity challenges against networking method patents reach the Federal Circuit
This case confirms that method patents covering TCP/IP connection management are actively contested through PTAB invalidity proceedings and subsequent Federal Circuit appeals. Companies building cloud infrastructure, network monitoring tools, or enterprise networking software should audit their exposure to similarly structured method claims before a challenge is filed against them.
Mutual cost-bearing dismissals signal negotiated IP exits — not defeats
When a Federal Circuit appeal ends under Rule 42(b) with each side bearing own costs, it typically suggests a commercial agreement was reached out of court. IP teams tracking Jenam Tech’s assertion behaviour should note that this entity appears willing to negotiate rather than pursue full merits adjudication — a pattern worth monitoring across their portfolio.
Jenam v Google — key questions answered
The appeal was dismissed by agreement under Federal Rule of Appellate Procedure 42(b) on January 9, 2024, with each side bearing its own costs. No merits ruling was issued. The case concerned the patentability of US10306026B1, covering methods for detecting idle TCP connections, in an underlying invalidity or cancellation proceeding.
Fed. R. App. P. 42(b) permits parties to jointly agree to dismiss a federal appellate proceeding at any time. The court enters dismissal without ruling on the merits. The default under 42(b)(2) is that each party bears its own costs unless otherwise agreed. It leaves the lower tribunal’s ruling in place without Federal Circuit endorsement or reversal.
US10306026B1 is a US patent held by Jenam Tech, LLC. It covers methods, systems, and computer program products for sharing information to detect idle TCP (Transmission Control Protocol) connections. This technology is relevant to network session management, server resource optimisation, load balancing, and connection monitoring in enterprise and cloud environments.
No. Because the appeal was dismissed by agreement before the Federal Circuit issued a merits ruling, the court did not rule on the patentability arguments. The validity determination from the lower tribunal — likely a PTAB proceeding — remains in place, but the Federal Circuit did not affirm, reverse, or modify it. The patent’s legal status was not publicly resolved by this appeal.
The public record does not disclose the reasons for the agreed dismissal. The 334-day timeline and mutual cost-bearing arrangement are consistent with a negotiated commercial resolution — potentially a licensing agreement or covenant not to sue — but this cannot be confirmed from the available court filings. Neither party disclosed any settlement terms in the dismissal order.
