Vieri v. Intuit: SMS Messaging Patent Dispute Dismissed With Prejudice After 203 Days
Individual patent holder Riccardo Vieri filed suit against Intuit, Inc. in the Eastern District of Texas, asserting US8156005B2 against the automated and personalized SMS messaging functionality in Intuit Mailchimp. The case ended after 203 days via a joint stipulation of dismissal with prejudice — both parties agreed to bear their own costs and attorneys’ fees.
Individual inventor targets Intuit Mailchimp’s SMS platform in East Texas
On September 23, 2024, individual plaintiff Riccardo Vieri filed a patent infringement action against Intuit, Inc. in the U.S. District Court for the Eastern District of Texas (Case No. 2:24-cv-00774), before Judge Rodney Gilstrap. Vieri asserted US8156005B2, a patent covering automated and personalized SMS messaging technology, against Intuit Mailchimp’s SMS system — a product that enables companies to send automated, targeted text messages to their customers.
The case resolved on April 14, 2025, when the parties filed a Joint Stipulation of Dismissal with Prejudice under Rule 41 of the Federal Rules of Civil Procedure. Judge Gilstrap acknowledged and accepted the stipulation, dismissing all claims Vieri raised or could have raised, as well as any counterclaims Intuit raised, with prejudice. Each party was ordered to bear its own costs and attorneys’ fees, suggesting the resolution was mutual and without a formal damages award to either side.
The 203-day duration suggests the dispute resolved before substantial court-ordered deadlines or claim construction proceedings — consistent with either a confidential licensing agreement or a decision by Vieri not to pursue the litigation further. The with-prejudice designation forecloses Vieri from refiling the same patent claims against Intuit. The public record does not disclose whether any financial consideration changed hands as part of the resolution.

Dismissed with prejudice: what the joint stipulation means for both parties
Rule 41 joint stipulation ends the case permanently
A dismissal with prejudice under Rule 41 of the Federal Rules of Civil Procedure is a final adjudication on the merits. Because both parties jointly stipulated to this outcome, no court ruling on patent validity or infringement was issued. However, the with-prejudice designation means Vieri is permanently barred from asserting the same claims in US8156005B2 against Intuit in any future action.
Rule 41 — permanent bar on refilingVieri loses the right to pursue Intuit again on this patent
With the case dismissed with prejudice, Vieri can no longer assert US8156005B2 against Intuit for the conduct alleged. The patent itself remains in force and could theoretically be enforced against other parties, but the litigation avenue against Intuit on these claims is closed. The own-costs order means Vieri received no fee award. Whether any confidential settlement consideration was exchanged is not disclosed in the public record.
Patent survives — Intuit claims extinguishedIntuit exits without a validity ruling — risk from third parties remains
Intuit secured a permanent resolution of Vieri’s claims without a court ruling on whether US8156005B2 is valid or infringed. While this is a commercially clean outcome — no injunction, no damages on record — the patent’s validity was never adjudicated. Other parties holding or licensing similar SMS patent rights retain the ability to assert them independently. Intuit’s Mailchimp SMS product continues operating without a declared non-infringement finding.
No validity ruling — third-party risk remainsAutomated SMS marketing patents remain an active enforcement risk
The filing of this action in the Eastern District of Texas signals that automated and personalized SMS messaging technology — now integral to marketing platforms like Mailchimp — continues to attract patent assertion activity. Businesses operating in the SMS marketing, CRM automation, or customer communications space should treat US8156005B2 as a reference point in any freedom-to-operate analysis, particularly given its early application date and broad claim scope in automated messaging workflows.

Official order — verbatim text
The court’s order reflects a textbook joint stipulation of dismissal with prejudice under Rule 41(a)(1)(A)(ii). Critically, the stipulation’s language — dismissing ‘all claims that Plaintiff raised or could have raised, and counterclaims Intuit raised’ — is broadly drafted, foreclosing not just the asserted claims but any claim Vieri might have withheld. No merits ruling on infringement or validity was issued, meaning US8156005B2 emerges from this litigation without judicial scrutiny of its claims.
US8156005B2 — automated and personalized SMS messaging for businesses
US8156005B2, filed under application number US12/206864, covers technology relating to automated and personalized SMS messaging systems — specifically the ability for businesses to send targeted, automated text communications to customers at scale. The patent’s application date positions it as an early-stage asset in the commercial SMS automation space, predating many of the modern API-driven messaging architectures now standard in marketing platforms. Its designation as a granted utility patent (B2) confirms it survived examination with allowable claims.
For the martech sector, this patent is strategically significant. Automated SMS messaging has become a core feature of customer engagement platforms — including Intuit Mailchimp, Klaviyo, Attentive, and comparable tools. A patent with an early priority date covering the mechanics of personalized, automated SMS delivery creates broad exposure for any platform offering similar functionality. Companies developing or acquiring SMS marketing capabilities should treat US8156005B2 as a key reference patent in FTO analyses, particularly given its assertion against a major enterprise platform.
Should you run an FTO against US8156005B2?
Any company building, acquiring, or expanding an automated SMS messaging product — including marketing automation platforms, CRM systems, customer communications tools, or CPaaS providers — should assess exposure against US8156005B2. The patent was actively asserted against Intuit Mailchimp’s SMS system in 2024, demonstrating that the holder is willing to pursue enforcement against large commercial platforms. Early-stage FTO analysis is significantly cheaper than full litigation defense.
