Freshub v. Whole Foods Market: Federal Circuit Affirms on Alexa Voice Shopping Patents
Freshub, Inc. challenged Amazon.com, Prime Now, Whole Foods, and related entities over four patents covering voice-activated shopping list processing, asserting infringement by Alexa’s shopping-list feature. The Federal Circuit affirmed the lower court ruling after 763 days, closing the appeal with no path to re-litigation on these claims.
Federal Circuit closes Freshub’s Alexa voice-shopping patent challenge
Freshub, Inc. and Freshub, Ltd. brought a patent infringement action asserting four US patents — US10232408, US10239094, US10213810, and US9908153 — against Amazon.com, Inc., Prime Now LLC, Amazon.com Services LLC, Whole Foods Market Services, Inc., and Whole Foods Market, Inc. The asserted patents relate to voice-activated shopping list processing technology, and the accused product was Amazon’s Alexa shopping-list feature. The appeal was filed at the Court of Appeals for the Federal Circuit on 24 January 2022.
The Federal Circuit issued an affirmance, upholding the outcome reached at the district court level and dismissing the appeal. An affirmance at the Federal Circuit means the appellate panel found no reversible error in the lower court’s analysis — whether on claim construction, validity, or infringement — and Freshub’s arguments failed to persuade the court to disturb the prior ruling. The case closed on 26 February 2024.
The 763-day duration of the appeal is consistent with the Federal Circuit’s typical docket pace for multi-patent infringement appeals involving large technology defendants. What remains unavailable in the public record is the specific basis on which the lower court ruled, the precise grounds the Federal Circuit relied upon in affirming, and whether any settlement discussions ran in parallel. The involvement of Kramer Levin Naftalis & Frankel on the plaintiff side suggests the litigation was well-resourced, making the affirmance a notable outcome for Freshub.

Federal Circuit affirms: what the ruling means for both parties
Affirmance locks in the district court result
When the Federal Circuit affirms, it endorses the lower court’s judgment without modification. For Freshub, this means the infringement claims against Alexa’s shopping-list feature have been rejected at both the trial and appellate level. Amazon and the Whole Foods entities retain the freedom to continue operating the accused feature without liability under these four patents, barring any further legal action such as a Supreme Court petition.
No reversal — lower court standsFour voice-processing patents — all asserted, all affirmed against
Freshub asserted US10232408, US10239094, US10213810, and US9908153 — a cluster of patents filed across 2017–2018 application numbers, all targeting voice-activated list and processing functionality. Asserting a family cluster rather than a single patent is a common strategy to broaden claim coverage. The affirmance suggests the court found none of the four patents provided a viable infringement theory against Alexa’s implementation.
Four-patent family — all affirmed againstAmazon’s entity structure shaped the defendant list
The defendant and co-plaintiff grouping reflects Amazon’s corporate structure: Amazon.com Inc., Prime Now LLC, Amazon.com Services LLC, and Whole Foods Market Services Inc. were named alongside Whole Foods Market Inc. as the lead defendant. This multi-entity naming is consistent with plaintiffs seeking to ensure all revenue-generating and service-operating entities are captured to maximise potential damages exposure — a strategy that did not ultimately prevail here.

A Federal Circuit affirmance on infringement typically precludes re-asserting the same claims against the same products and parties under the doctrine of res judicata. Freshub may retain rights to assert these patents against third parties or different products, and could theoretically petition the Supreme Court for certiorari, but the practical enforcement path against Amazon’s Alexa feature appears closed by this decision.

Stipulation of dismissal — official text
The Federal Circuit’s single-word disposition — AFFIRMED — indicates the appellate panel found no reversible error in the district court’s handling of the infringement claims across all four asserted patents. For Amazon and Whole Foods, this is a complete appellate vindication: the Alexa shopping-list feature is cleared of liability under Freshub’s patent portfolio at this level. For Freshub, the affirmance forecloses re-litigation against these parties on these claims, though the patents themselves remain in force against other potential infringers.
US10232408, US10239094, US10213810 & US9908153 — Voice-Activated Shopping List Processing
The four patents asserted by Freshub — US10232408, US10239094, US10213810, and US9908153 — share a technical focus on processing voice inputs to populate and manage shopping lists, a capability that sits at the intersection of automatic speech recognition, natural language processing, and e-commerce. The application numbers indicate filings clustered in 2017–2018, placing them squarely in the rapid-growth phase of consumer voice assistant adoption. This timing suggests Freshub sought to capture second-generation voice-commerce functionality as Alexa’s grocery and shopping capabilities were expanding.
For competitors and product teams in the voice-commerce space, this patent family represents an attempt to claim the workflow of converting spoken item requests into structured shopping list entries. The technology domain is now crowded, with Amazon, Google, Apple, and multiple startups holding overlapping prior art and granted patents. The failure of these claims against Alexa at both trial and appellate level may reflect claim scope limitations rather than invalidity — meaning the patents could still pose risk to companies whose voice-list implementations differ architecturally from Amazon’s. Independent FTO analysis remains essential for any product team shipping voice-activated grocery or retail features.
Should your voice-commerce product run an FTO against Freshub’s patent family?
Any product team developing voice-activated shopping list, grocery ordering, or list-management features should treat Freshub’s four-patent family as a live FTO consideration. The Federal Circuit affirmance clears Amazon’s specific Alexa implementation — it does not invalidate the patents or limit their enforceability against other products. Companies building on third-party voice platforms, developing proprietary NLP-to-list pipelines, or integrating voice commands into retail apps are squarely in the technical scope these patents were drafted to cover.
PatSnap Eureka’s FTO Search Agent can map your product’s feature set against the claim language of US10232408, US10239094, US10213810, and US9908153, surfacing both literal and doctrine-of-equivalents risk. Eureka’s claim monitoring alerts your team if Freshub or a successor owner files continuations, divisionals, or related applications that could extend coverage. Given that this patent family survived litigation without being invalidated, ongoing claim monitoring is as important as the initial FTO clearance.

What this case signals for the voice-commerce IP landscape
The Federal Circuit’s affirmance reinforces Amazon’s defensive position in voice-commerce and raises important questions for any company asserting shopping-list patents against big-tech AI assistants.
Patent clusters against single features face appellate scrutiny
Freshub’s strategy of asserting four related patents against one Alexa feature did not produce a different appellate outcome. For patent holders in the voice-AI space, this case suggests that claim breadth across a family is not a substitute for claim specificity. Courts and juries appear willing to reject multi-patent infringement theories when the accused product’s architecture diverges from asserted claims.
Amazon’s entity shield held — naming subsidiaries added complexity, not leverage
Despite naming five Amazon-affiliated entities including Prime Now LLC and Whole Foods Market Services, Freshub could not convert the multi-defendant structure into a litigation advantage. IP teams pursuing large platform companies should model whether entity-level naming genuinely broadens damages exposure or simply increases litigation cost without changing the substantive infringement analysis.
Freshub v Whole — key questions answered
The Federal Circuit affirmed the lower court’s decision on 26 February 2024, dismissing Freshub’s appeal. Freshub had asserted four patents covering voice-activated shopping list processing against Amazon entities and Whole Foods, claiming infringement by Alexa’s shopping-list feature. The affirmance means the district court’s ruling in favour of the defendants was upheld in full.
Freshub asserted four US patents: US10232408 (application US16/103394), US10239094 (application US15/905591), US10213810 (application US16/131979), and US9908153 (application US15/604422). All four relate to voice-activated list and shopping processing technology and were filed in the 2017–2018 window.
Not necessarily. An affirmance on infringement means the court agreed the accused product — Amazon’s Alexa shopping-list feature — did not infringe the asserted claims, or that other grounds justified the lower court ruling. It does not automatically invalidate the patents. Freshub’s patents remain in force and could potentially be asserted against different parties or products, subject to the specific grounds of the lower court’s ruling.
Freshub named Amazon.com Inc., Prime Now LLC, Amazon.com Services LLC, Whole Foods Market Services Inc., and Whole Foods Market Inc. as parties. This multi-entity approach is a standard plaintiff strategy to capture all corporate entities involved in developing, operating, and monetising the accused Alexa feature, thereby maximising potential damages exposure across Amazon’s corporate structure.
The case confirms that Amazon’s Alexa shopping-list implementation was found non-infringing at both trial and appellate level — but Freshub’s four patents were not invalidated. Companies developing their own voice-to-list or voice-commerce features should conduct independent freedom-to-operate analysis against this patent family, as the clearance applies specifically to Amazon’s architecture and does not protect third-party implementations.
