US 10810579

US patent 10810579, titled "Smart tokenizing payment card and device and transaction processing thereof, system and method," has the following details:

• Assignee: Virtual Electric Inc (Original Assignee); CardWare Inc (Current Assignee via reassignments in 2022).
• Inventors: David Wyatt.
• Filing Date: July 1, 2019 (Application No. US16/459,150).
• Issue Date: October 20, 2020.
• Abstract: The patent describes a credit card device that can generate a programmed magnetic field with alternating polarity, adapting to the speed of a card swipe to emulate a standard credit card. It also details methods for user control to authorize credit, debit, cash, cryptocurrency, and card-to-card transactions. A key security feature involves generating a limited-duration, limited-use credit card number for transactions. The device can also interact with other similar devices for fund transfers.

Here is a plain-language overview of the independent claims based on the "Summary of the Invention" section of the patent:

1. Claim 1 (Apparatus for Emulating a Magnetic Stripe): This claim describes a thin, card-shaped device. It includes memory to store multiple identification data (like credit card numbers), a processor, and a user interface for selecting one of these data sets. The device has a magnetic card reader detection unit to sense when it's near a standard magnetic card reader. An inductor assembly, controlled by the processor, generates an alternating magnetic field in the area of the reader when detected. This magnetic field encodes the selected identification data and can be read by the magnetic read head of a standard card reader.
2. Claim 2 (Credit Card Device for Card-to-Card Transactions): This claim describes a credit card device featuring a near-field communication (NFC) unit, a touch sensor array, a display, a motion rate detection array, and memory storing user and currency data. A processor in the device initiates card-to-card transactions between itself and another similar credit card device. This initiation occurs when the devices are detected to be in proximity, and a user provides input via the touch sensor array. The card-to-card transaction involves exchanging stored currency and user data between the two devices using their NFC units.
3. Claim 3 (Method of Performing a Transaction with Limited-Duration Numbers): This claim outlines a method for conducting a transaction using a credit card device. It involves receiving an input signal from a user that activates the device's near-field communication (NFC) unit (which was previously disabled). The device then receives an indication of the currency amount for the transaction. Following this, the credit card device generates a limited-duration credit card number, which is then transmitted to the transaction recipient. This limited-duration number is restricted in its usage, typically to a predetermined number of authorized transactions or a specific time period.

A search of the CAFC 2026 dockets for patent number 10810579 did not yield any direct results for cases specifically using this patent number in the Court of Appeals for the Federal Circuit dockets as of the current date. Similarly, direct searching on USPTO for specific litigation status within dockets is not a typical function of the public search interface, which primarily provides patent prosecution history and assignments. The information on district court and PTAB litigation is sourced from the Google Patents page, which aggregates data from various sources, including Unified Patents, indicating ongoing litigation activity related to this patent.
