Patent Number: 10,643,266 B2

Title: System and method for in-app payments

Assignee: Monticello Enterprises LLC

Inventors: Thomas M. Isaacson, Ryan Connell Durham

Filing Date: February 19, 2019

Issue Date: May 5, 2020

Abstract:
The present disclosure describes systems and methods for providing a software module on a device that simplifies online and in-app payments. This is achieved by eliminating the need for users to manually enter payment or address information on various websites or within applications. The technology facilitates a "one-click" purchasing experience across different platforms by utilizing a browser or software module to store and securely transmit user data.

Plain-Language Summary of Independent Claims:

This patent includes several independent claims, which are the broadest statements of the invention. The core concepts of these claims are summarized below:

• Claim 1: This claim describes a method for a unified shopping experience. A user can browse a product on a first website and, even without purchasing it, the product information is stored. Later, when the user is on a second, different website and initiates a purchase for another product, the system presents an interface that includes both the new product and the previously viewed product from the first website. This allows the user to purchase both items from different merchants in a single, streamlined transaction. The browser facilitates the communication of payment and shipping information to both websites to complete the separate purchases.

• Claim 11: This claim focuses on the perspective of the first merchant's website in the unified shopping cart scenario. It outlines a method where the first website sends information about a product viewed by a user to the user's browser. Even though the user doesn't buy the product at that time, the browser stores this information. Later, when the user is on a second website and decides to buy another item, the first website can receive a request to process the purchase of its product as part of that same transaction. The browser provides the necessary payment and shipping details to the first website to finalize the sale.

• Claim 14: This claim describes the system that enables the methods in the previous claims. It details a computer-readable medium with instructions that, when executed by a processor, perform the steps of the unified shopping cart process. This includes receiving and storing information about a product from a first website, and then, during a purchase on a second website, presenting the option to also buy the first product and processing both purchases together by communicating the necessary information to both websites.

Litigation Status:

A search of the CAFC (Court of Appeals for the Federal Circuit) dockets for 2026 did not reveal any pending or recent appellate litigation specifically involving US Patent 10,643,266. However, it is noted from the patent's file history that this patent family has been involved in district court litigation.

As of April 26, 2026, the following litigation involving US Patent 10,643,266 is known:

• Plaintiff(s): Monticello Enterprises LLC

• Defendant(s): [Apple Inc.](/litigations/by-plaintiff/Apple%20Inc.)

• Jurisdiction: Texas Western District Court

• Case Number: 6:23-cv-00753

• Filing Date: (Not explicitly provided in the search results, but the case number indicates 2023)

• Outcome/Current Status: Active litigation is indicated for this patent family in the Texas Western District Court.

• Plaintiff(s): Monticello Enterprises LLC

• Defendant(s): Apple Inc.

• Jurisdiction: Texas Western District Court

• Case Number: 6:23-cv-00761

• Filing Date: (Not explicitly provided in the search results, but the case number indicates 2023)

• Outcome/Current Status: Active litigation is indicated for this patent family in the Texas Western District Court.

• Plaintiff(s): Monticello Enterprises LLC

• Defendant(s): Apple Inc.

• Jurisdiction: Texas Western District Court

• Outcome/Current Status: Active litigation is indicated for this patent family in the Texas Western District Court.

Please note that while the provided patent text mentions "US case filed in Texas Western District Court" with these case numbers, it does not specify the defendants for these particular entries. However, other search results indicate Monticello Enterprises LLC as a plaintiff and Apple Inc. as a defendant in cases related to patent litigation.
No specific CAFC (Court of Appeals for the Federal Circuit) dockets for 2026 were found that explicitly mention US Patent 10,643,266.

Proceedings overview

There are no AIA trial proceedings on file for US Patent 10,643,266. This indicates that, as of the most recent data from the USPTO Open Data Portal and supplementary web searches, the patent has not been subjected to inter partes review (IPR), post-grant review (PGR), or covered business method (CBM) patent review. This gives a defendant no specific claim-level invalidation to leverage from PTAB proceedings.

Strategic summary

As there are no PTAB proceedings on file for US Patent 10,643,266, all claims (Claims 1-14) remain untested by the PTAB. This means there are no claims that have been canceled or sustained through an AIA trial process.

Consequently, there is no estoppel landscape established under § 315(e)(2) for this patent. All prior-art grounds and statutory bases (§ 102, § 103, § 112) remain available for a potential defendant to raise in a new PTAB petition or district court litigation.

The absence of PTAB activity suggests that either the patent has not been extensively asserted, or previous assertions have not prompted petitioners to challenge its validity at the PTAB. There is no pattern of multiple IPR filings by the same petitioner, aggressive PTAB appeals by the patent owner, or involvement of defensive aggregators like Unified Patents.

Recommended next steps

Since no PTAB activity exists for US Patent 10,643,266, a defendant currently facing assertion of this patent should consider evaluating its claims against prior art to determine the viability of filing an IPR or PGR petition. This absence of prior challenges means the patent has not been "hardened" by surviving PTAB scrutiny.

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.

Obviousness Analysis of US Patent 10,643,266 under 35 U.S.C. § 103

Patent: US 10,643,266 B2
Title: System and method for in-app payments
Priority Date: March 31, 2014
Analysis Date: May 31, 2026

This analysis examines whether the independent claims of US Patent 10,643,266 would have been obvious to a person having ordinary skill in the art (PHOSITA) as of the priority date of March 31, 2014, based on the prior art landscape described within the patent itself.

Prior Art Landscape (as of March 31, 2014)

The patent document explicitly identifies several existing technologies, problems, and conceptual solutions that form the basis of the prior art landscape:

• Existing E-commerce and Browser Functionality (Reference A): Online shopping was widespread, featuring merchant-specific shopping carts where users could browse and add products. Web browsers commonly used cookies and local storage for session management, user preferences, and autofill functionalities for forms, including address and basic payment fields [cite: "the system can inspect and use browser cookies from other sites to glean user data, glean search history, or any other information stored in or made available via cookies."].
• Limited "One-Click" Purchasing and Manual Data Entry Problems (Reference B): "One-click" purchasing, notably pioneered by Amazon.com, existed to simplify transactions but was restricted to Amazon's ecosystem [cite: "Some sites like Amazon.com provide a “one-click” purchasing option but those simplifications are only available in the controlled Amazon.com environment."]. For other merchants, the "long-standing problem of requiring users to enter payment data such as credit card information and a user address when making a purchase" was a known issue, often leading to abandoned shopping carts, particularly on mobile devices [cite: "An additional issue relates to the long-standing problem of requiring users to enter payment data such as credit card information and a user address when making a purchase.", "Purchasing concerns can include complicated shopping cart models which require too much data (payment account, address, name, etc.), particularly on a mobile device, causing people to abandon the cart"].
• Multi-site Shopping Cart Concepts and Purchase Management Challenges (Reference C): The concept of a multi-site shopping cart was known to exist, though often undesirable for users due to requirements for separate registration or payment information to the service [cite: "a multi-site shopping cart might exist, it likely requires the user to register or provide payment information to the service, which can be undesirable for the user."]. The proliferation of "buy buttons" on non-merchant sites (e.g., Google, Facebook, Instagram) introduced the challenge of managing purchases spread across "uncoordinated, disparate sites" [cite: "presenting buy options at non-merchant sites to take advantage of such micro-moments introduces the difficulty of managing purchases spread across uncoordinated, disparate sites."].
• Browser Extensions and Payment Service Integration (Reference D): Browser extensions were available to enhance browser functionality, including password managers and form fillers that could store and automatically input user data, including payment and address details, across various websites upon user authorization. External payment services like PayPal and Apple Pay already provided interfaces for easily processing payments by abstracting payment details from merchants [cite: "an interface with PayPal® or Apple Pay is provided such that purchases can be easily processed."].

Core Invention of Independent Claims (1, 11, 14)

The independent claims collectively describe a system and method for a unified, browser-centric shopping experience that integrates products from multiple, distinct merchant sites into a single purchase flow. This includes:

• Receiving and storing product information from a first site (where a purchase was not completed) within or accessible by the browser.
• Initiating a purchase for a second product on a second site.
• Presenting a unified browser payment interface that includes information about both the first and second products.
• Processing the payment for both products through browser-facilitated communication (via APIs) to their respective merchant sites in a streamlined manner, often without manual re-entry of payment or address data.

Obviousness Combination and Motivation

A PHOSITA in March 2014, motivated by the pervasive desire to reduce friction in online purchasing, extend "one-click" convenience beyond single-merchant ecosystems, and simplify the management of cross-site purchases, would have found it obvious to combine the elements described in References A, B, C, and D to arrive at the claimed invention.

Motivation for Combination:
The patent itself clearly articulates the problems that motivated its invention:

1. Reducing Purchase Friction: The "long-standing problem of requiring users to enter payment data" [cite: "An additional issue relates to the long-standing problem of requiring users to enter payment data such as credit card information and a user address when making a purchase."] and the high abandonment rates for complicated shopping carts, particularly on mobile devices [cite: "Purchasing concerns can include complicated shopping cart models which require too much data (payment account, address, name, etc.), particularly on a mobile device, causing people to abandon the cart"], created a strong motivation to simplify the payment process. The success of Amazon's one-click purchasing (Reference B) demonstrated the user demand for such convenience.
2. Harmonizing Disparate Shopping Experiences: The emergence of "buy buttons" on non-merchant sites presented a new challenge: "there is no existing mechanism of harmonizing or organizing purchases such that users can easily manage purchases" [cite: "buy buttons are expanding, there is no existing mechanism of harmonizing or organizing purchases such that users can easily manage purchases."]. This motivated the need for a unified approach to track and purchase items from various sources.
3. Improving Cross-Site Shopping: While "a multi-site shopping cart might exist" [cite: "a multi-site shopping cart might exist, it likely requires the user to register or provide payment information to the service, which can be undesirable for the user."], the existing solutions were cumbersome. A PHOSITA would be motivated to improve upon these by leveraging existing browser capabilities to avoid separate registrations and simplify data entry.

Combination Steps and Rationale Leading to Claims 1, 11, and 14:

1. Browser-Managed Product Interest Tracking (References A, C): Given that browsers already stored user data (Reference A) and extensions could manage cross-site data for autofill (Reference D), it would have been obvious for a PHOSITA to extend a browser's capabilities (either natively or via an extension) to record user interest in a product on a first site (even without purchase). This could be initiated by a user interaction (e.g., dwelling on a product page, adding to a browser-managed "wishlist" or "potential purchase" list) or triggered by a simple "add to cart" action on the merchant's site that the browser's enhanced functionality intercepts and stores. This directly addresses the problem of losing information about items not purchased immediately.
2. Unified Browser Interface for Multi-Merchant Checkout (References A, B, C): Building on the known concept of multi-site shopping carts (Reference C) and the desire for streamlined purchasing (Reference B), it would be an obvious next step to present a browser-controlled interface that aggregates items of interest from various sites. When a user initiates a purchase on a second site, this browser interface would display both the current item and the previously stored item(s) from other sites, allowing for a consolidated view of potential purchases. This leverages the browser's role as a central point of user interaction (Reference A).
3. Browser-Facilitated Payment and Delivery (References B, D): To address the "long-standing problem of requiring users to enter payment data" (Reference B) and extend the "one-click" experience, a PHOSITA would logically integrate the browser's existing autofill capabilities (Reference D) with this unified checkout. Upon user confirmation within the browser's payment interface, the browser (or its extension/module) would securely transmit the stored payment and address data to each relevant merchant site. This could be achieved through a standardized Application Programming Interface (API), which is a common and obvious method for inter-system communication, or by programmatically simulating form submissions. This effectively allows the user to make a single "click" (or minimal interaction) to complete multiple purchases across different merchants, with the browser orchestrating the individual transactions and providing the necessary payment and shipping information. The "browser payment request application programming interface" and "browser shopping cart application programming interface" are thus obvious means to formalize and standardize these interactions given the existing technologies and user needs.

Conclusion

The independent claims of US Patent 10,643,266, encompassing a browser-centric system for aggregating items from multiple sites and facilitating their purchase through a unified interface using browser-stored payment and address data, would have been obvious to a PHOSITA as of the priority date. The motivation stemmed from clear and well-understood problems in online commerce, including the tediousness of manual data entry, the limitations of single-merchant "one-click" solutions, and the challenges of managing purchases across a fragmented online landscape. The combination of existing browser capabilities (data storage, autofill), conceptual multi-site shopping solutions, and established payment service integrations would have led a PHOSITA to develop the claimed invention with a reasonable expectation of success.

To determine the complete patent term adjustments (PTA), patent term extensions (PTE), continuation applications, divisional applications, related family members, and the precise projected expiration date for US patent 10,643,266, I would ideally need to access the official Public Patent Application Information Retrieval (PAIR) system or the Patent Center provided by the USPTO. The provided text from Google Patents offers some details, but not a full breakdown of all these elements. However, based on the information provided in the patent text, I can derive the following:

Patent Term Adjustments (PTA) and Patent Term Extensions (PTE):
The provided patent text does not explicitly state whether any Patent Term Adjustments (PTA) or Patent Term Extensions (PTE) were granted for US 10,643,266. PTA is granted to compensate for USPTO delays during patent prosecution, while PTE is awarded for delays incurred in obtaining regulatory approval on a patented product. Without access to the official USPTO records for this specific patent, I cannot determine the exact PTA or PTE amount.

Related Family Members:
The extensive list of priority claims indicates that US 10,643,266 is part of a large patent family, all generally relating to "System and method for in-app payments." All the patents listed above in the "Priority Claimed From" and "Other Versions/Priority to" sections are related family members, representing various continuations, continuations-in-part, or divisional applications that share common subject matter and priority dates.

Projected Expiration Date:
The basic patent term for utility patents in the United States is 20 years from the earliest non-provisional filing date. US 10,643,266 claims priority from US14/230,864, which has a prior art date of 2014-03-31. This is the earliest priority date provided in the patent text.

Therefore, without any PTA or PTE, the statutory term of US 10,643,266 would typically be 20 years from this earliest priority date (2014-03-31).

• 20-year term from earliest priority date (2014-03-31): March 31, 2034.

The patent text explicitly states an "Anticipated expiration" date as 2034-03-31. This matches the calculation of 20 years from the earliest priority date, suggesting that no significant PTA has been applied, or if applied, it did not alter the publicly anticipated expiration date as displayed on Google Patents.

Summary:

• Patent Term Adjustments (PTA): Not explicitly stated in the provided text.
• Patent Term Extensions (PTE): Not explicitly stated in the provided text. PTEs are typically related to regulatory approval delays for products like drugs or medical devices.
• Continuation Applications / Divisional Applications / Related Family Members: The patent is part of a large family with numerous continuation, continuation-in-part, and divisional applications, as evidenced by the extensive list of priority claims and other versions provided. The earliest priority date is March 31, 2014.
• Projected Expiration Date: March 31, 2034. This is based on 20 years from the earliest priority date of March 31, 2014, and is corroborated by the "Anticipated expiration" date in the provided patent information.
