In re Maplebear Inc.: Federal Circuit Mandamus Petition Dismissed in 69 Days
Maplebear Inc. sought extraordinary relief at the Federal Circuit via a writ of mandamus petition tied to the patentability of US9454748B2, a system and method for data management. The petition was dismissed after Maplebear filed an unopposed motion to dismiss — ending the proceeding without a merits ruling just 69 days after filing.
Maplebear’s Mandamus Bid Ends Before Federal Circuit Weighs In
On October 22, 2025, Maplebear Inc. (operator of Instacart) filed a petition for a writ of mandamus at the Court of Appeals for the Federal Circuit, docketed as Case No. 26-105. The petition concerned the patentability of US9454748B2, which covers a system and method for data management — a software architecture patent with potential relevance to Maplebear’s platform infrastructure. Mandamus is an extraordinary remedy typically sought to compel or prohibit a lower tribunal’s action when no other adequate relief exists.
The case closed on December 30, 2025, just 69 days after filing. Maplebear moved to dismiss its own petition, and that motion was unopposed — meaning no other party contested the dismissal. The Federal Circuit granted the motion to the extent of dismissing the petition. No merits ruling was issued. The underlying patentability dispute was not adjudicated at the appellate level, and the public record does not disclose the specific trigger for withdrawal.
The rapid resolution and Maplebear’s voluntary withdrawal without opposition suggests the underlying dispute may have been resolved through separate proceedings, a settlement, or a strategic reassessment of the mandamus route. Mandamus petitions carry a high bar — petitioners must show a clear and indisputable right to relief — and withdrawal before briefing is complete may indicate that bar became difficult to satisfy. What drove the decision to dismiss remains unknown from the public record.

Petition dismissed: what Maplebear’s withdrawal means for the patent
Mandamus petition dismissed — no merits ruling reached
The Federal Circuit dismissed the petition on Maplebear’s own unopposed motion, meaning the court made no determination on whether mandamus relief was warranted or on the underlying patentability question. A dismissed mandamus petition leaves the lower tribunal’s proceedings — most likely at the USPTO or PTAB — exactly where they stood before the petition was filed. No precedential legal finding was established.
Procedural dismissal — no meritsMaplebear exits without a ruling — but also without a loss on record
Because the dismissal was procedural and unopposed, Maplebear does not carry an adverse Federal Circuit ruling. However, the company also failed to obtain the extraordinary relief it sought. The patentability status of US9454748B2 is unaffected by this proceeding at the appellate level. Maplebear retains the ability to pursue other avenues — including further PTAB proceedings or district court litigation — depending on how the underlying dispute evolves.
No adverse ruling on recordUS9454748B2 patentability question remains open
The dismissal means the Federal Circuit expressed no view on the validity or patentability of US9454748B2. Any invalidity or cancellation action affecting this patent — likely pending before the USPTO or PTAB — continues on its existing trajectory. Third parties with freedom-to-operate concerns regarding this data management patent should monitor the underlying proceeding, which this mandamus petition was seeking to influence.
Underlying dispute unresolvedData management patent remains a live risk factor for platform operators
US9454748B2’s patentability status is unresolved at the appellate level. For software platform companies operating data management architectures similar to Instacart’s, the underlying PTAB or USPTO proceeding continues to carry commercial relevance. A patent that survives cancellation proceedings can be enforced against competitors. Companies in adjacent data management and e-commerce infrastructure spaces should track the downstream outcome of the underlying invalidity action.

Official order — verbatim text
The Federal Circuit’s order is narrowly procedural: the court granted Maplebear’s motion ‘to the extent that the petition is dismissed’ — language that confirms no substantive relief was granted or denied. The court made no finding on whether mandamus was warranted, and no ruling on the patentability merits of US9454748B2. The phrase ‘to the extent that’ is standard hedging language preserving the court’s discretion but changes nothing substantively here. Both parties — and third-party observers — should treat this as a procedural termination only.
US9454748B2 — System and Method for Data Management
US9454748B2, filed under application number US12/910706, protects a system and method for data management — a category of software architecture patents covering how data is structured, accessed, and manipulated within a platform environment. This patent sits within the broader domain of software-implemented business and infrastructure methods, a space that has been subject to heightened patentability scrutiny under Alice Corp. v. CLS Bank since 2014. The patent’s grant predates several major PTAB rule changes, making its claim language worth careful examination.
For platform operators — particularly in e-commerce, SaaS, and order-fulfillment — data management architecture patents represent a category of IP that can reach across competitive product stacks. US9454748B2’s involvement in a Federal Circuit mandamus proceeding suggests its claim scope is contested at the validity level, which typically signals that at least one party believes the patent’s claims are either overbroad or insufficiently novel. Companies building competing data infrastructure should assess whether their architectures fall within or outside the asserted claim scope before the underlying PTAB proceeding concludes.
Should you run an FTO analysis against US9454748B2?
Any R&D team or product organisation developing data management systems, platform infrastructure, or order-fulfillment architectures in the e-commerce or SaaS space should consider whether US9454748B2 presents an FTO concern. The patent’s enforceability has not been resolved by this Federal Circuit proceeding — it remains a granted US patent. Until the underlying invalidity or cancellation proceeding concludes, the patent can still be asserted. That window of uncertainty is exactly when an FTO review adds the most value.

What this case signals for the data management IP landscape
A withdrawn mandamus petition rarely ends the underlying story — the patentability fight on US9454748B2 is likely still live elsewhere.
Mandamus withdrawal typically signals a strategic pivot, not a concession
When a petitioner voluntarily dismisses an unopposed mandamus petition, it often suggests the underlying conditions changed — a settlement, a favourable PTAB development, or a reassessment of whether mandamus was the right vehicle. Patent counsel monitoring Maplebear’s IP posture should track USPTO and PTAB dockets for US9454748B2 activity post-dismissal.
US9454748B2 remains enforceable until a cancellation is finalised
No Federal Circuit ruling affects the patent’s validity. For product teams building data management or order-fulfillment platform architecture, US9454748B2 represents an unresolved encumbrance. An FTO analysis covering this patent and its claim scope is advisable before launching competing systems in this space.
In v Defendant — key questions answered
Maplebear Inc. filed a mandamus petition at the Federal Circuit on October 22, 2025, concerning the patentability of US9454748B2. On December 30, 2025, the court granted Maplebear’s own unopposed motion to dismiss the petition. No merits ruling was issued. The case closed in 69 days without any Federal Circuit adjudication of the underlying patentability dispute.
A writ of mandamus is an extraordinary remedy directing a lower tribunal to take or refrain from a specific action. In Federal Circuit patent practice, mandamus petitions are typically filed when a party believes a tribunal — such as the PTAB or a district court — has acted outside its authority and no adequate alternative remedy exists. The high bar for mandamus means petitions are rarely granted on the merits.
No. The Federal Circuit’s dismissal was procedural and made no ruling on the patentability of US9454748B2. The patent’s validity status is determined by the underlying USPTO or PTAB proceeding, which this mandamus petition was seeking to influence. US9454748B2 remains a granted US patent until and unless a cancellation proceeding or court ruling holds otherwise.
The public record does not disclose the reason for Maplebear’s withdrawal. Common reasons for voluntary mandamus dismissal include: resolution of the underlying dispute through settlement or PTAB ruling, a strategic reassessment of whether mandamus was the appropriate vehicle, or changed circumstances making the petition moot. The motion was unopposed, which may suggest coordination with other parties.
Practitioners should monitor USPTO and PTAB dockets for any inter partes review, post-grant review, or ex parte reexamination proceedings involving US9454748B2. The mandamus petition was tied to an invalidity or cancellation action — that underlying proceeding is likely still active and will be the next significant legal event determining the patent’s enforceability. An FTO analysis covering US9454748B2 claim scope is advisable for companies in the data management platform space.
