US 10664070

The patent information has been extracted from the provided text. Now I need to summarize the independent claims in plain language and then address the USPTO and CAFC docket search.

Plain-language overview of each independent claim:

• Claim 1 (Interactive device): This claim describes an interactive device (like a mobile phone or PDA) that includes a special stylus. The stylus sends out a beam of electromagnetic radiation (like infrared light). The device also has a display screen (which acts as a touch-sensitive surface) and a sensor array located near the screen. This sensor array detects the light beam from the stylus. A processing unit in the device then figures out the pattern of the detected light, uses this pattern to determine the stylus's 3D position relative to the device, and identifies if this position corresponds to an icon on the screen. If it does, and a part of the detected light pattern indicates a "selection" action (like moving the stylus closer), the device performs the function associated with that icon.
• Claim 10 (Interactive system): This claim is very similar to Claim 1 but describes an "interactive system" rather than an "interactive device." It also specifies that the processing unit is in communication with the sensor array. The key steps are determining a distribution pattern of the emitted radiation, using that to find the stylus's 3D position, linking that position to a selectable icon, interpreting a portion of the pattern as a selection function, and then executing the related function.
• Claim 16 (Method for interacting): This claim describes a method (a series of steps) for a user to interact with a mobile device. The method involves the stylus emitting a beam of electromagnetic radiation, the mobile device's display screen showing icons, and a sensor array detecting the beam. The device's processor then determines the light beam's pattern, uses it to find the stylus's 3D position, identifies an icon at that position, determines if the beam indicates a selection action, and finally executes the function related to that icon.

USPTO and CAFC 2026 dockets search for US10664070:

The Google search results provided a lot of information about general CAFC activity in 2026 and USPTO search tools, but no specific docket information for patent US10664070 in the CAFC for 2026 was returned. The USPTO search results point to general search tools like Patent Public Search and Assignment Center, but don't provide a direct "docket" for a specific patent number in the same way that CAFC dockets would.

The patent itself, in its "Legal status" section, mentions:

• "Family has litigation"
• "First worldwide family litigation filed" with a link to darts-ip.com
• "PTAB case IPR2022-00315 filed (Final Written Decision)" with a link to unifiedpatents.com
• "US case filed in Texas Eastern District Court" with a link to unifiedpatents.com (case 2:21-cv-00348)
• "US case filed in Court of Appeals for the Federal Circuit" with a link to unifiedpatents.com (case 23-2121)

While the patent document itself indicates past litigation related to this patent family, including a CAFC case (case 23-2121), the search for "CAFC 2026 dockets" for this specific patent did not yield any new or ongoing 2026 cases. The CAFC cases mentioned in the Google search results are recent but do not specifically mention patent 10664070.

Therefore, while there's a history of litigation, based on the current search, there's no explicit mention of an ongoing CAFC docket specifically for US10664070 in 2026. The information about the PTAB case (IPR2022-00315) and the Texas Eastern District Court case (2:21-cv-00348) are provided in the patent document itself and reflect past or concluded actions as of its publication/status update, rather than current 2026 CAFC docket activity directly from my search.
The current date is April 26, 2026. The "Legal Status" section of the patent states "Expired - Lifetime" and "Anticipated expiration 2023-06-09". This indicates the patent has already expired. If a patent has expired, it is highly unlikely there would be active litigation in 2026, especially at the CAFC level for infringement, although other types of actions (e.g., related to inventorship or prior IPRs) might still be present. The search for "US patent 10664070 CAFC 2026 dockets" did not return any specific active 2026 dockets for this patent.

I have all the necessary information to construct the response.

Title: Input system for controlling electronic device

Assignee: Power2B Inc.

Inventors: Robert Michael Lipman, Sarah Michelle Lipman

Filing Date: March 7, 2018

Issue Date: May 26, 2020

Abstract: An electronic device is described, featuring a display for data, an input means (such as a stylus), and a sensing means to detect the input means' three-dimensional position relative to the device. The device's control means then adjusts the displayed data based on this 3D position. The input means uses a source of electromagnetic radiation (e.g., an infrared conical beam) directed at the display. The sensing means can determine the stylus's angle relative to the display by sensing the elliptical eccentricity of the incident radiation, and its distance from the display by sensing the area of the incident radiation.

Plain-Language Overview of Independent Claims:

• Claim 1 (Interactive Device): This claim describes an interactive device that includes a stylus emitting an electromagnetic beam and a display screen with a touch-sensitive surface. A sensor array near the display detects the beam. A processing unit receives the sensor data, determines the beam's pattern, calculates the stylus's 3D position relative to the device based on this pattern, and determines if that position aligns with a selectable icon. If a part of the detected pattern indicates a selection, the processing unit executes a function associated with that icon.
• Claim 10 (Interactive System): This claim is similar to Claim 1 but focuses on an "interactive system." It includes the stylus, display screen (touch-sensitive), sensor array, and a processing unit communicating with the sensor array. The processing unit determines the electromagnetic radiation's distribution pattern, uses it to determine the stylus's 3D position relative to the device, correlates this position with a selectable icon, interprets a portion of the pattern as a selection function, and then executes the function related to the icon.
• Claim 16 (Method for Interacting): This claim outlines a method for interacting with a mobile device. The steps include a stylus emitting an electromagnetic beam, a display screen showing icons (forming a touch-sensitive plane), and a sensor array detecting the beam. A processor then determines the beam's distribution pattern, calculates the stylus's 3D position relative to the device, identifies an icon corresponding to this position, determines if the beam indicates a selection action for that icon, and finally executes the icon's related function.

USPTO and CAFC 2026 Docket Information:
As of April 26, 2026, searches of CAFC 2026 dockets for US patent 10664070 did not return any specific active cases directly naming this patent in 2026. The patent's Google Patents page indicates "Expired - Lifetime" status with an anticipated expiration date of June 9, 2023, suggesting the patent is no longer in force. The patent document itself notes a history of litigation, including a PTAB case (IPR2022-00315), a US case filed in the Texas Eastern District Court (2:21-cv-00348), and a US case filed in the Court of Appeals for the Federal Circuit (23-2121). These entries reflect past or concluded legal actions related to the patent family. There is no authoritative information from current 2026 CAFC dockets specifically identifying active litigation for US10664070.
