Salesforce and Intuit Petition for Inter Partes Review of Three IQX Network Authentication and Webpage Patents.

The parties and the patents

The Salesforce proceedings are Salesforce, Inc. v. IQX Corp., IPR2026-00475 (U.S. Patent 12,368,799), IPR2026-00476 (U.S. Patent 11,876,924), and IPR2026-00477 (U.S. Patent 12,200,165). The Intuit proceedings are Intuit Inc. v. IQX Corp., IPR2027-00017 (the '924 patent) and IPR2027-00018 (the '799 patent). The '799 patent, issued July 22, 2025, is titled Automated Silent Network Authentication Protocol. The '924 patent, issued January 16, 2024, is titled Secure Transactions Using Customized Webpages. The '165 patent, issued January 14, 2025, is titled Automated Silent Network Authentication Protocol Security, Verification, and Access Control for Cellular Handheld Devices.

What the claims cover

Claim 1 of the '799 patent covers a system with a processor and memory whose instructions provide a hosted input field for inclusion in a first document associated with a third party; receive, when the field is activated, an electronic address and an indication of willingness to receive messages; generate a second document, customized to the user, with information about events of interest; send a message with a link to that document; and, when the link is activated, provide the second document to facilitate completing a transaction. Claim 1 of the '924 patent covers a computer-implemented method that subscribes a service subscriber associated with a telephone number to receive additional content once the subscriber has previously provided authentication information, activates customized webpages with a customized actionable item for an e-commerce transaction, including generating secure access information, where the item corresponds to the subscriber's prior transactions, and generates and transmits a third party message containing that item. Claim 1 of the '165 patent covers a computer-implemented method that sends a customized message with an action to an authorized recipient's mobile computing device, requests and verifies authorization data when the action is selected, classifies the recipient, generates a Rich Communication Service (RCS) message with the content, and uses a machine learning model to schedule its delivery based on that classification.

The grounds

Every ground in all five petitions is obviousness under 35 U.S.C. 103. Salesforce challenges claims 1 to 30 of the '799 patent, claims 1 to 20 of the '924 patent, and claims 1 to 20 of the '165 patent. Each Salesforce petition argues that the challenged claims are not entitled to the 2018 provisional priority date, so that a published application in the patents' own priority chain, U.S. Patent Application Publication 2022/0006895, is prior art. In IPR2026-00475, on the '799 patent, the first set of grounds combines Balasubramanian (U.S. Patent Application Publication 2011/0178897), Wertheimer (U.S. Patent Application Publication 2017/0013295), and Chen (U.S. Patent 7,020,685), alone or with Bogineni (U.S. Patent 10,264,413) or Sinha (U.S. Patent Application Publication 2016/0239867). The second set combines Publication 2022/0006895 with Long (U.S. Patent 11,170,380), alone, with Anderson (U.S. Patent Application Publication 2015/0052061), or with Wang (International Publication WO 2018/103039) and Bogineni. In IPR2026-00476, on the '924 patent, Ground 1 relies on Balasubramanian alone, and Ground 2 combines Publication 2022/0006895 with Anderson. In IPR2026-00477, on the '165 patent, the first set of grounds combines Balasubramanian, Chen, and Sinha, alone or with Bogineni, Burr (U.S. Patent Application Publication 2016/0005070), or Jakobsson (U.S. Patent Application Publication 2020/0067976). The second set combines Publication 2022/0006895 with Long and Wang, with the same additional references. Intuit challenges claims 1 to 20 of the '924 patent in IPR2027-00017 as obvious over Long (U.S. Patent 11,553,074, a different patent from the Long reference in the Salesforce petitions) alone or with Gaddis (U.S. Patent Application Publication 2012/0310752), and over Louie (U.S. Patent 10,360,627) alone or with Gaddis. Intuit challenges claims 1 to 30 of the '799 patent in IPR2027-00018 as obvious over Ghadialy (U.S. Patent Application Publication 2007/0150588) with Gaddis and Lentz (U.S. Patent Application Publication 2018/0365723), and over Wendkos (U.S. Patent Application Publication 2005/0228899) with Teeter (U.S. Patent Application Publication 2005/0278231) and Lentz. Each petition is supported by a technical expert's declaration.

Related matters

IQX sued Intuit on April 30, 2026 in IQX Corp. v. Intuit Inc., No. 2:26-cv-00351 (E.D. Tex.), asserting the '924 and '799 patents. That case is assigned to District Judge Rodney Gilstrap and referred to Magistrate Judge Roy S. Payne, and Intuit answered the complaint on June 26, 2026. IQX sued Salesforce on May 28, 2026 in IQX Corp. v. Salesforce, Inc., No. 7:26-cv-00213 (W.D. Tex.), in the Midland/Odessa Division, asserting the '924, '165, and '799 patents and U.S. Patent 12,438,978. That case is assigned to Judge David Counts. Each Salesforce petition names Salesforce, Inc. as the real party in interest, and Salesforce's petition on the '924 patent lists IPR2026-00478, on U.S. Patent 12,438,978, as a concurrently filed Salesforce petition. Both Intuit petitions name Intuit Inc. as the real party in interest.

What to watch next

Under 37 CFR 42.107(b), IQX may file a preliminary response in each proceeding within three months of the notice according the petition a filing date. Under the USPTO's interim Director discretionary process, any discretionary denial brief from IQX is due within two months of that notice. Watch for the filing-date notices, those filings, and the institution decisions across the Salesforce and Intuit petitions.
