The other listed patent applications (US20190230070A1, US10726472B2, US10511580B2, US11250493B2, US11282131B2, US11244377B2, US10650443B2, US10650441B1, US10769717B2, US10825079B2, US11080777B2, US11074640B2, US10977716B2, US11989769B2, US20210174428A1, US11669884B2, US20210350443A1, US11842380B2, US11461828B2, US11468497B2, US12045868B2, US12008629B2, US11915303B2, US12236471B2, US20240112245A1, US12131370B2, US12148021B2, US20250095048A1, US20250200643A1, US20250166047A1, US12400254B2, US20250378474A1) are either later publications within the same family or continuations, and therefore would not be considered prior art to US10643266B2 under 35 U.S.C. § 102 as they have later filing dates or priority dates.

Regarding other potential prior art, general concepts like "collaborative shopping using shared virtual shopping cart" have been discussed in the past, for example, in an IBM patent application from 2013. However, without the specific patent number, it's difficult to ascertain its direct relevance to the precise claims of US10643266B2. Similarly, "intelligent shopping cart" (US5729697A) and "shopping cart" (US6926291B1) refer to physical shopping carts with integrated technology, which are distinct from the software-based multi-site shopping cart described in US10643266B2. A Walmart patent application for a "biometric feedback cart handle" also relates to physical shopping carts and customer behavior within a physical store, not online in-app payments across multiple merchants.
