Summary of U.S. Patent No. 10,846,031 (US10846031B2)
Important caveat up front: The Google Patents full-text fetch provided in the prompt was truncated before the formal abstract and the claims section. I have verbatim text of claim 1 only, sourced from the assignee's own site (flexiworld.com) and corroborated by the PGR record. I could not verify the full claim set (number of claims or text of the other independent claims) from authoritative sources, and I found no CAFC 2026 docket for this patent. Items marked with "⚠" reflect that uncertainty.

Abstract ⚠
The fetched full text did not include the formal abstract field. Based on the specification and title, the invention is directed to a software application for a mobile information apparatus (e.g., a smartphone) that wirelessly discovers, manages, and/or sets up an output system or output device (e.g., a printer, display, or audio output device) for service — enabling "universal" wireless output without installing device-specific, device-dependent drivers. The underlying technology (shared raster-image processing, intermediate output data, output controllers) is described at length in the specification.
Independent claims — plain-language overview
The full claims section was not available in the fetched text. What follows is claim 1 verbatim (from http://www.flexiworld.com/patent/us-10846031/, corroborated by the PGR record at PGR2021-00111, which compared "10,846,031 Patent Claim 1"), followed by a plain-language explanation. I could not verify whether there are additional independent claims (e.g., a method claim or an output-system-side claim) — ⚠ treat the claim count as unverified.
Claim 1 (paraphrased structure): A non-transitory computer-readable storage medium storing software executable at a mobile information apparatus to wirelessly set up an output system (which has wireless communication circuitry, is associated with at least one output device for output of digital content, and is a separate device from the mobile apparatus). The mobile apparatus includes: a touch-sensitive screen, memory storing at least part of the software, one or more processors, and one or more wireless communication units with RF link controllers. When executed, the mobile apparatus:
- Wirelessly discovers the output system, based at least in part on physical proximity;
- Displays a user-interface item/icon for the discovered output system on the touch screen;
- Obtains a user selection of that icon via the touch screen;
- Wirelessly provides security or authentication information to the output system to facilitate access to the output system's services;
- Wirelessly establishes a wireless communication link — a direct short-range link (e.g., Bluetooth-type) or a WLAN (e.g., Wi-Fi) link — based on the selection; and then accesses the output system's services over that link, contingent on having provided the security/authentication information.
Plain language: This is essentially a "wireless printer/TV/speaker setup app." A phone or tablet app finds nearby wireless output devices based on how close they are, shows them as tappable icons on the touchscreen, lets the user pick one, sends credentials or authentication data to it so the user is authorized to use it, establishes a Bluetooth-style direct or Wi-Fi connection, and then uses that connection to send content to the device for printing, display, or audio playback — without the user installing a separate manufacturer-specific driver for each device.

- Formal abstract: not present in the fetched full text; summarized from the specification instead.
- No CAFC 2026 activity found: absence of evidence in search results, not a definitive negative.

Assignment history
Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
Prior art
Earlier patents, publications, and products that may anticipate or render the claims unpatentable.
