Jenam Tech v. Google: Federal Circuit Appeal Dismissed by Mutual Agreement
Jenam Tech, LLC appealed to the U.S. Court of Appeals for the Federal Circuit against Google, LLC over two patents covering methods for detecting idle TCP connections. The parties reached agreement to dismiss the appeal under Fed. R. App. P. 42(b) within 334 days, with each side bearing its own costs.
Mutual dismissal in a Federal Circuit TCP networking patent appeal
Jenam Tech, LLC filed this appeal at the U.S. Court of Appeals for the Federal Circuit on 9 February 2023, challenging a lower-level patentability determination relating to two patents — US10306026 and US10069945 — which cover methods, systems, and computer program products for detecting idle TCP connections. The defendant and appellee was Google, LLC, represented by a six-attorney team from Paul Hastings, LLP. The underlying verdict cause was an invalidity or cancellation action, suggesting the patents had been challenged on patentability grounds before a tribunal such as the Patent Trial and Appeal Board.
The appeal closed on 9 January 2024 when the parties filed a joint agreement to dismiss under Federal Rule of Appellate Procedure 42(b). The court’s order confirmed two things: the proceeding is dismissed, and each side shall bear its own costs. This structure — mutual dismissal with no cost shifting — is a hallmark of a privately negotiated resolution, whether a licensing settlement, a covenant not to sue, or some other commercial arrangement, though the specific terms remain confidential and are not disclosed in the public record.
The 334-day duration from filing to dismissal is consistent with parties reaching an agreement before full appellate briefing or oral argument concluded. Early resolution at the Federal Circuit typically signals either a deterioration in one party’s confidence in the appeal or, more commonly, a commercial settlement that made continued litigation economically irrational. What drove the agreement — licensing terms, portfolio cross-licensing, or simply a desire to avoid further legal spend — cannot be confirmed from the public docket.

Fed. R. App. P. 42(b) — what a voluntary dismissal means here
Rule 42(b) permits parties to voluntarily dismiss an appeal by agreement filed with the court. Unlike a court ruling on the merits, this order carries no precedential weight on the underlying patent validity questions. The patents’ status following dismissal depends on what was resolved at the lower tribunal level — the appeal’s dismissal does not itself cancel the patents.
No merits rulingEach side bears own costs — what the public record is silent on
The order specifies that each party bears its own appellate costs. This is a neutral cost outcome — neither party was awarded fees under 35 U.S.C. § 285 or Rule 39. However, this dismissal was agreed without the court specifying whether it is with or without prejudice. The public record is silent on whether Jenam Tech retains the right to refile related claims; that distinction may have been resolved in a private side agreement between the parties.
No cost shiftingUnderlying invalidity action — what was at stake in this appeal
The verdict cause is classified as an invalidity/cancellation action, consistent with an inter partes review or post-grant proceeding at the PTAB targeting US10306026 and US10069945. An appeal to the Federal Circuit in this posture typically challenges a PTAB finding that one or more claims are unpatentable. Dismissal before a Federal Circuit decision means no appellate ruling on the validity of the asserted claims was issued.
PTAB appeal contextJoint agreement suggests private resolution, not litigation fatigue alone
A bilateral Rule 42(b) dismissal with symmetric cost-bearing is structurally consistent with a licensing deal, a covenant not to sue, or a broader IP settlement between the parties. If Google resolved the matter commercially, it may have acquired a license or secured agreement that the patents would not be further asserted. Neither outcome can be confirmed from the public record, but the symmetric cost order suggests neither side extracted a clear litigation victory.

Stipulation of dismissal — official text
The court’s order is purely procedural: it confirms the parties’ agreement and imposes no finding on patent validity, infringement, or claim construction. The symmetric cost order — each side bears its own costs — reflects a negotiated exit rather than a litigation outcome. No precedent on the patentability of the idle TCP connection detection claims was established. The absence of a merits ruling leaves the underlying patents’ legal status dependent entirely on what the lower tribunal determined before this appeal was filed.
US10306026 & US10069945 — Idle TCP Connection Detection Methods
US10306026 (application no. US16/040517) and US10069945 (application no. US15/915053) both protect methods, systems, and computer program products for sharing information to detect an idle TCP connection. TCP — Transmission Control Protocol — is the foundational connection protocol for internet communications. Detecting idle or stale connections is operationally critical for server resource management, cloud infrastructure efficiency, and mobile network performance. These patents sit at the intersection of networking protocol implementation and software-defined connection management.
For any company operating large-scale internet infrastructure, cloud services, or connection-intensive applications, this patent family represents a meaningful validity and infringement risk vector. The fact that Jenam Tech pursued Google — one of the world’s largest operators of TCP-dependent infrastructure — to the Federal Circuit level suggests the patentee believed the claims had commercial scope broad enough to cover hyperscale deployments. The resolution without a merits ruling leaves the claim scope legally unresolved, which is relevant for any third party operating in the same technical space.
Should your product team run an FTO against US10306026 and US10069945?
Any engineering or product team building connection management features, session keep-alive systems, load balancers, proxies, or mobile network gateways that handle TCP connection state should consider a freedom-to-operate review against this patent family. The claims appear directed at software-implemented detection of idle TCP connections — a function embedded in a wide range of server, cloud, and networking products. The absence of a Federal Circuit validity ruling means these patents have not been definitively invalidated at the appellate level.
PatSnap Eureka’s FTO Search Agent can map your product’s connection management architecture against the claim language of US10306026 and US10069945, identifying overlap risk and surfacing prior art that could support a design-around or invalidity argument.

What this case signals for the networking and cloud IP landscape
A quick Federal Circuit exit in a TCP patent dispute involving Google carries meaningful signals for patent holders and product teams in the networking and cloud infrastructure space.
TCP connection management remains an active patent assertion target
The assertion of two patents covering idle TCP connection detection against a hyperscaler like Google confirms that seemingly foundational networking protocol patents continue to attract enforcement activity. Product and engineering teams building connection management layers, keep-alive mechanisms, or session-monitoring tools should treat this patent family as a live monitoring priority.
Early Federal Circuit dismissals signal commercial resolution pressure
When parties agree to dismiss a Federal Circuit appeal this quickly — before full briefing in many cases — it typically suggests the economics of the dispute shifted. Whether through licensing or a covenant not to sue, Google appears to have resolved its exposure to these patents without a court ruling on validity. This pattern is common when the cost of appeal outweighs the cost of resolution.
Jenam v Google — key questions answered
The appeal was dismissed by mutual agreement under Fed. R. App. P. 42(b) on 9 January 2024. The parties agreed that each side would bear its own costs. No merits ruling on the patentability of US10306026 or US10069945 was issued by the Federal Circuit.
Jenam Tech asserted US10306026 (application no. US16/040517) and US10069945 (application no. US15/915053). Both patents cover methods, systems, and computer program products for sharing information to detect an idle TCP connection.
A Rule 42(b) dismissal is procedural and carries no ruling on the merits of the patent validity dispute. The Federal Circuit issued no opinion on whether the claims of US10306026 or US10069945 are valid or invalid. The patents’ legal status depends on the outcome of the lower tribunal proceedings that preceded this appeal.
The joint dismissal by agreement is consistent with a private settlement, though no settlement terms are disclosed in the public record. The symmetric cost order — each side bears its own costs — suggests a negotiated exit rather than a concession by either party, but whether a license, covenant, or other arrangement was reached cannot be confirmed from publicly available filings.
Yes. The patents cover methods for detecting idle TCP connections — a function relevant to servers, cloud infrastructure, proxies, and mobile gateways. The Federal Circuit issued no invalidity ruling, leaving the claims legally unresolved. Companies in this space should conduct FTO analysis against US10306026 and US10069945 and monitor for continuation filings from the same family.
