IP Law Daily, PATENT—N.D. Cal.: Messaging privacy technology company’s infringement lawsuit against Meta dismissed, (Apr 7, 2025)

By Saurabh Kashyap, B.A., LL.B., LL.M.

A disappearing-message patent was found ineligible under § 101 because it claimed an abstract idea and failed to add an inventive concept beyond conventional computer use.

A federal district court in California dismissed a patent infringement lawsuit filed by Lavoult.com, LLC against Meta Platforms, Inc., Instagram LLC, and WhatsApp Inc., holding that the asserted patent claims failed both steps of the Alice framework and were ineligible for patent protection under 35 U.S.C. § 101. The court found that the patent was directed to an abstract idea—confidential messaging with automatic deletion—and failed to recite any inventive concept that would transform it into a patent-eligible application. The dismissal was with prejudice, as the court concluded the amendment would be futile (LaVoult.com, LLC v. Meta Platforms, Inc., No. 3:24-cv-06724-JSC (N.D. Cal. Apr. 4, 2025)).

Background. The plaintiff, Lavoult.com, LLC, is a technology company that owns U.S. Patent No. 8,751,594 (the ’594 patent), issued in June 2014 and titled “Communication Method Using Selective Message Storage.” The patent describes a messaging system where users toggle between two modes: a regular mode, in which messages are saved in memory, and a confidential mode, in which messages are not stored and are automatically deleted upon exiting that mode. The invention claims to offer enhanced privacy for communications through this switchable interface.

In September 2024, Lavoult.com sued the defendant Meta and its subsidiaries in the Northern District of California, alleging infringement of Claim 1 of the '594 patent through the operation of Instagram's "Vanish Mode" and WhatsApp's "Disappearing Messages" features. The complaint alleged Meta had offered these features since at least 2016 and that each infringed the claimed messaging method. Meta moved to dismiss the complaint under Rule 12(b)(6), contending that the ’594 patent was invalid as a matter of law under 35 U.S.C. § 101.

Abstract idea. Applying the Supreme Court’s framework from Alice Corp. v. CLS Bank Int’l, 573 U.S. 208 (2014), the court first examined whether the claims were directed to an abstract idea. Because Lavoult did not challenge Meta’s assertion that Claim 1 was representative, the court focused its analysis on that claim.

Claim 1 recited a communication method involving a switch between two modes of electronic messaging, where messages in confidential mode are automatically deleted when a user exits that mode. The court found that the claimed advance was the concept of classifying messages as confidential or regular and deleting them accordingly—an idea that could be executed by human action, such as passing handwritten notes and shredding the confidential ones after reading.

Relying on precedent such as RingCentral, Inc. v. Dialpad, Inc., 372 F. Supp. 3d 988 (N.D. Cal. 2019), the court determined that the claim simply described conventional mental steps—identifying and deleting confidential content. The automation of this process via computer did not by itself make the claim non-abstract. The court noted that "doing this in a computer environment doesn't transfigure the idea out of the realm of abstraction" and emphasized that the core of the invention could be analogized to manual methods.

Lavoult argued that the system improved message privacy and reduced storage, but the court found these benefits flowed directly from the abstract concept itself and were not tied to any improvement in computer functionality. The court distinguished Enfish, LLC v. Microsoft Corp., 822 F.3d 1327 (Fed. Cir. 2016), which upheld claims improving database architecture, noting that Lavoult’s claim involved no such technical advance.

Inventive concept. At the second step of the Alice inquiry, the court considered whether the claim contained an “inventive concept” sufficient to transform the abstract idea into a patent-eligible application. The court held that Claim 1 lacked such an inventive concept.

The court emphasized that all steps of the claim—composing, sending, switching modes, and deleting messages—could be performed by humans, and the specification merely applied those steps to a generic computer environment. The claim’s use of a server to transmit messages and memory to store them relied on conventional computer components and added nothing inventive. Citing Realtime Data LLC v. Array Networks Inc., No. 2021-2251, 2023 WL 4924814 (Fed. Cir. Aug. 2, 2023), and Trinity Info Media, LLC v. Covalent, Inc., 72 F.4th 1355 (Fed. Cir. 2023), the court concluded that these generic terms provided only a “generic technical environment” for performing the abstract idea.

Lavoult argued that using different types of memory (permanent for regular mode, temporary for confidential) constituted an inventive concept, but the court found that neither the claim nor the specification supported this interpretation. The specification described memory in generic terms and did not distinguish between memory types in a way that could transform the idea.

The court also rejected Lavoult’s reliance on Bascom Global Internet Servs., Inc. v. AT&T Mobility LLC, 827 F.3d 1341 (Fed. Cir. 2016), and Amdocs (Israel) Ltd. v. Openet Telecom, Inc., 841 F.3d 1288 (Fed. Cir. 2016), finding that the ’594 patent lacked the kind of unconventional technical architecture or computer improvement those cases endorsed.

The prior art disclosed in the specification itself described automatic deletion features in existing apps, including "delete on read" functionality and time-delayed deletion, undermining Lavoult's claim that automated deletion was novel. The court concluded that Claim 1 contained no inventive steps beyond what was already known and abstract.

Amendment deemed futile. Finally, the court held that any amendment would be futile and dismissed the complaint with prejudice. The court noted that Lavoult failed to identify any specific factual allegations or claim construction arguments that could salvage the patent's eligibility. Even if the claims were amended to clarify the use of "temporary" and "permanent" memory, the court reasoned that these remained generic computer components and would not satisfy Alice Step Two.

Quoting Trinity Info Media, the court noted that “[n]o amendment to a complaint can alter what a patent itself states.” Because Lavoult offered no basis to conclude that the claim, properly construed, could become patent-eligible, dismissal with prejudice was warranted.

The Case is No. 3:24-cv-06724-JSC.
