Defendant
3 cases as defendant.
Xandr, Inc. (pronounced "Zander") is a New York City–headquartered advertising-technology company founded on September 25, 2018. It was assembled from AT&T's advertising businesses — principally AppNexus, which AT&T acquired in 2018 for a reported ~$1.6 billion, plus the AdWorks unit. Xandr operated as an AT&T advertising and analytics subsidiary until AT&T agreed in December 2021 to sell it to Microsoft; the transaction closed June 6, 2022 (reported value roughly $1 billion, though terms were undisclosed). Xandr is therefore now a Microsoft subsidiary, and its separate brand was retired in 2023 when its platforms were renamed under Microsoft Advertising.
Products / services. Xandr operates a programmatic digital-advertising marketplace serving both the buy and sell sides: Xandr Invest (demand-side platform), Xandr Monetize (supply-side platform), Xandr Curate (data and inventory marketplace), and Invest TV for television/connected-TV buying. These offerings were rebranded Microsoft Invest, Microsoft Monetize, and Microsoft Curate in 2023. Predecessor AppNexus reported 1,000+ employees; a current, verified standalone headcount or revenue figure for Xandr is not publicly disclosed.
Patent-litigation posture. The structured data show Xandr as a defendant in all three tracked cases and as plaintiff in none — the profile of an operating company being attacked rather than an entity asserting patents. All three suits are brought by AlmondNet, Inc. and related plaintiffs, a known patent-assertion entity, against Microsoft Corporation and related defendants including Xandr.
Notable cases / context. The tracked matters are AlmondNet, Inc. et al. v. Microsoft Corporation et al. (filed 2022-11-18) and AlmondNet, Inc. et al. v. Microsoft Corp. et al. (filed 2021-08-27), plus one undated entry, all in the Western District of Texas. Two are assigned to Waco Division, where Judge Alan D. Albright's court is a frequent venue for patent plaintiffs. The cases concern targeted-advertising technology, matching the digital-ad targeting functions of Xandr/Microsoft's advertising platforms. No merits determinations are asserted here.
AlmondNet II. Defendants' Answer expressly admits Plaintiffs allege infringement of, among others, U.S. Patent 8,775,249; asserted patents also included '260, '307, '146, and '878. The case was consolidated into the 6:21-cv-00897 action and resolved by the same June 2024 dismissal with prejudice.
AlmondNet and Intent IQ sued Microsoft and Xandr in W.D. Tex., asserting ten patents including U.S. 9,830,615, with claims 9-12 asserted against Microsoft. The case was dismissed with prejudice by joint stipulation in June 2024, each side bearing its own fees and costs, and was consolidated with the later 6:22-cv-01206 Microsoft case.
'586 appears in the asserted-patent list reported for this case. Resolved by dismissal with prejudice by stipulation under Fed. R. Civ. P. 41(a)(1)(A)(ii), each side bearing its own fees/costs. No merits adjudication.
