US 11966920

US patent 11966920, titled "Method and system for presenting representations of payment accepting unit events," was issued on April 23, 2024, to PayRange LLC. The inventor is Paresh K. Patel. The application was filed on May 14, 2023.

Abstract:
The patent describes a method for a mobile device to present representations of events occurring at a payment-accepting unit (e.g., a vending machine). The method involves the mobile device obtaining a notification from a payment module, connected to the payment-accepting unit, via a short-range communication capability. This notification indicates an event at the payment-accepting unit. The mobile device then provides a representation of this notification to the user through its output devices, such as a display, vibrator, or speaker. Events can include transaction completion, fund payment, fund refund, or changes in the unit's status.

Independent Claims Overview:

1. Claim 1 (Method): This claim covers a method performed by a mobile device. The method involves the mobile device receiving a notification from a payment module (which is connected to a payment accepting unit) through a short-range communication channel. This notification signals an event that has occurred at the payment accepting unit. Subsequently, the mobile device displays or otherwise presents a representation of this notification to the user.
2. Claim 9 (Mobile Device System): This claim describes a mobile device itself as a system. The mobile device is characterized by having one or more processors, memory, output devices, and at least two communication capabilities. Crucially, the mobile device is configured to perform the method steps outlined in Claim 1: obtaining a notification from a payment module about an event at a payment accepting unit and then presenting a representation of that notification to the user.
3. Claim 17 (Non-Transitory Computer-Readable Storage Medium): This claim is directed to a non-transitory computer-readable storage medium (e.g., a hard drive or flash memory). This medium stores one or more programs containing instructions. When these instructions are executed by a mobile device (with its processors, memory, output devices, and communication capabilities), they cause the mobile device to carry out the method steps specified in Claim 1, namely receiving payment accepting unit event notifications and presenting them to the user.

Litigation Status:
US11966920 is currently active and has a litigation family associated with it. There is a PTAB case, PGR2025-00027, which is pending and has been instituted.

Strategic summary

Currently, there is one active Post-Grant Review, PGR2025-00027, challenging US11966920, with PayRange LLC as the Patent Owner and Alliance Laundry Systems, LLC as the Petitioner. This proceeding was instituted on August 25, 2025, and a Final Written Decision is due imminently, around August 25, 2026. The specific claims challenged and the asserted prior art or statutory grounds are not explicitly detailed in the provided public information. Therefore, all claims of US11966920 are currently untested by a Final Written Decision, although they are being actively challenged in this PGR.

Regarding the estoppel landscape, if a Final Written Decision is issued in PGR2025-00027, the petitioner, Alliance Laundry Systems, LLC, and its privies would be estopped under 35 U.S.C. § 315(e)(2) from asserting in other proceedings any ground of unpatentability that they raised or reasonably could have raised during the PGR. Without knowing the specific claims and grounds, it is impossible to define the exact scope of potential estoppel. The existence of this PGR, initiated by Alliance Laundry Systems, LLC, also signals that this patent has drawn attention from potential defendants or aggregators.

Recommended next steps

The Final Written Decision for PGR2025-00027 is due around August 25, 2026, which is very soon (within days of the current date). A defendant facing assertion of this patent should closely monitor this proceeding for the issuance of the Final Written Decision. The FWD will determine the patentability of the challenged claims and provide crucial insight into the patent's validity. If claims are invalidated, the disposition of the FWD will be critical for crafting a defense.

Given that the FWD is expected to be issued imminently, the next step is to obtain and thoroughly review the Final Written Decision in PGR2025-00027 once it is publicly available on the USPTO PTAB Decisions portal. This document will detail which claims, if any, were canceled or held patentable, and the Board's reasoning. This information will directly inform the viability of any claims currently being asserted against a defendant.

To identify the most relevant prior art for US patent 11966920, I will examine the patent citations listed within the patent document itself. The USPTO's Patent Public Search tool is the authoritative source for this information.

Once I have the list of cited prior art, I will perform the following for each reference:

1. Full Citation: Extract the patent number, inventor(s), and publication date.
2. Publication/Filing Date: Note both the publication date and, if available and relevant for § 102 analysis (especially for "secret prior art" under pre-AIA 35 U.S.C. § 102(e)), the effective filing date.
3. Brief Description: Summarize the invention disclosed in the cited prior art.
4. Potential Anticipation under 35 U.S.C. § 102: Analyze which claims of US11966920 might be anticipated by the prior art, meaning the prior art discloses every limitation of at least one claim.

Please note that for a comprehensive anticipation analysis, the full text of each cited patent would need to be reviewed against the full text of the claims of US11966920, which is beyond the scope of a brief analysis. This analysis will focus on identifying potential areas of anticipation based on the titles and abstracts of the cited references where available.

I will now proceed to search the USPTO database for US patent 11966920 to retrieve its cited prior art.I am unable to directly access the USPTO database or specific patent documents to extract the list of prior art citations for US patent 11966920. My previous search results indicated how to access such a database (Patent Public Search, Google Patents) but did not provide the actual list of citations for this specific patent.

Therefore, I cannot provide a detailed analysis of the most relevant prior art, their descriptions, or which claims they potentially anticipate without the specific list of cited references.

To proceed, I would need the "References Cited" section of US patent 11966920.

For a proper obviousness analysis under 35 U.S.C. § 103, specific prior art references are typically cited that predate the patent's effective filing date and are not part of its own priority chain for the claimed subject matter. In the provided information, US patent 11966920 (US11966920B2) claims priority from US14/214,644 (which matured into US8856045B1) with a priority date of December 18, 2013. If the claims of US11966920 are fully supported by the disclosure of US8856045B1 (or its underlying provisional application), then US8856045B1 would not constitute prior art against those claims.

However, for the purpose of this exercise, and to address the prompt's request to "Identify combinations of prior art references that would render the claims obvious," we will proceed with a hypothetical analysis. This analysis assumes that the specific claims of US11966920, while extensively described within its own specification and closely related to its priority documents, might be considered in combination with general knowledge in the art if their full scope or specific elements were deemed not entirely inherent or explicitly called out in prior disclosures in isolation.

Independent Claims of US11966920:

1. Claim 1 (Method): A method performed at a mobile device, comprising obtaining a notification from a payment module (associated with a payment accepting unit) via a first communication capability (e.g., short-range communication), where the notification indicates an event at the payment accepting unit, and providing a representation of this notification to a user via the mobile device's output devices.
2. Claim 9 (Mobile Device System): A mobile device system (with processors, memory, output devices, and two or more communication capabilities) configured to perform the method of Claim 1.
3. Claim 17 (Non-Transitory Computer-Readable Storage Medium): A non-transitory computer-readable storage medium storing instructions that, when executed by a mobile device, cause the device to perform the method of Claim 1.

The core of these claims lies in a mobile device receiving event notifications from a payment accepting unit (via an adapter module and short-range communication) and then presenting these notifications to the user.

Prior Art References and General Knowledge:

1. US8856045B1 (Method and system for processing transactions): This patent, issued October 7, 2014, and claiming priority to December 18, 2013, describes a mobile-device-to-machine payment processing system. The specification of US11966920 extensively details this system, referring to the adapter module (100), payment accepting unit (120), mobile device (150) with an application (140), and communication via short-range (e.g., Bluetooth) and long-range networks.

   • Teaching of Claim Elements from US8856045B1 (as described in US11966920):
     • Mobile device with capabilities: US8856045B1's system utilizes a mobile device 150 (e.g., smartphone) with processors, memory, and communication capabilities (short-range for adapter module, long-range for server). It implicitly includes output devices like a display and speaker, common to all smartphones.
     • Obtaining a notification from a payment module via short-range communication, indicating an event: US8856045B1 teaches that "details of the transaction are preferably returned to the mobile device 150" from the adapter module 100 via short-range communication (e.g., Bluetooth). This transfer of transaction details (e.g., successful vend, change returned) clearly constitutes obtaining a "notification" indicating an "event" at the payment accepting unit. For example, "After the selection is made, the change is returned to the mobile device 150."
     • Providing a representation of the notification to a user via output devices: US8856045B1 explicitly states that the returned change "may be shown on the touch screen 152 of the mobile device 150." The patent's own definitions for US11966920 further clarify that providing a representation includes "a message displayed on a display of the mobile device, a vibration produced by a vibration mechanism of the mobile device, an aural alert produced by a speaker of the mobile device, and/or the like."

2. General Knowledge in Mobile Application (App) and User Interface (UI/UX) Design (as of 2013-2014): At the time of the effective priority date, it was well-established practice in the design of mobile applications, especially those interacting with external systems (like payment systems), to provide users with clear and timely feedback regarding system events. This feedback commonly employed various output modalities of a mobile device.

Obviousness Analysis:

Combination: US8856045B1 in view of General Knowledge in Mobile UI/UX Design

A person having ordinary skill in the art (PHOSITA) in mobile payment systems as of December 2013 would have found the claims of US11966920 obvious based on the teachings of US8856045B1 combined with common knowledge in mobile application and user interface design.

Reasoning for Obviousness:

1. Primary Disclosure (US8856045B1): US8856045B1 comprehensively describes a mobile-device-to-machine payment system wherein a mobile device communicates with an adapter module connected to a payment accepting unit via short-range communication. Crucially, it teaches the transfer of transaction-related information (e.g., credit, change) from the payment module to the mobile device. The patent further explicitly states that information such as "change is returned to the mobile device 150 and this may be shown on the touch screen 152 of the mobile device 150." This directly teaches a mobile device obtaining a notification of an event (e.g., a refund/change event) and providing a visual representation of it.

2. Motivation to Combine/Modify with General Knowledge: Even if US8856045B1 did not explicitly list every conceivable type of "event" notification (e.g., "transaction completion," "fund payment," "fund refund," or "status change" as enumerated in US11966920's abstract) or every possible type of "representation" (e.g., vibration, aural alert, beyond visual display), a PHOSITA would have been highly motivated to implement these.

   • Improved User Experience: Providing clear and immediate feedback to the user about transaction status and events is a fundamental principle of good UI/UX design. Users expect confirmation of successful actions (e.g., payment accepted, product vended) and alerts for unsuccessful ones (e.g., vend failed, insufficient funds).
   • Standard Practice: Utilizing the various output capabilities of a mobile device (visual display, vibration, audio alerts) for notifications was a well-known and standard practice in mobile application development by the priority date. Different types of notifications are suited for different contexts (e.g., a silent vibration for a subtle alert, an aural alert for critical information, a visual display for detailed information).
   • Common Technical Goal: The overall goal of US8856045B1 was to enable and streamline mobile payments for unattended machines. Enhancing the user's awareness of transaction events through intuitive feedback mechanisms directly serves this goal by increasing user confidence and satisfaction.

Therefore, a PHOSITA, starting with the mobile payment system described in US8856045B1, would have readily and predictably implemented mechanisms for the mobile device to receive and present representations of various payment accepting unit events using the device's output capabilities (display, vibrator, speaker), drawing upon the routine skills and common design principles prevalent in the field of mobile application development. The claims would thus be rendered obvious by the combination of US8856045B1 and the general knowledge of UI/UX design for mobile applications.
