Title: Multiple-body-configuration multimedia and smartphone multifunction wireless devices

Key Information

• Assignee: Fractus, S.A.
• Inventors: Carles Puente Baliarda, Josep Mumbru, and Jordi Ilario.
• Filing Date: December 21, 2006
• Issue Date: May 27, 2014
• Abstract: The patent describes a multifunction wireless device, such as a smartphone or multimedia device, that has at least two body portions that can move relative to each other (e.g., slide, twist, or clamshell). The device includes a specialized internal antenna system designed for these complex, multi-part configurations. The antenna's performance is characterized by specific "complexity factors" that allow for efficient operation in a compact space. The invention also covers devices with advanced features like high-resolution cameras, large storage capacities, and the ability to run sophisticated software applications.

Summary of Independent Claims

This patent has three independent claims, each defining a multifunction wireless device with a unique combination of features.

• Claim 1 describes a multifunction wireless device with at least two body parts that can move in relation to each other, such as in a clamshell, slide, or twist design. This device contains an antenna system with a specific geometric complexity, defined by two "complexity factors," F21 (between 1.05 and 1.80) and F32 (between 1.10 and 1.90). This claim focuses on the physical, multi-body structure of the device in combination with the intricately designed antenna.

• Claim 15 focuses on the "smartphone" capabilities of a multifunction wireless device. It specifies a device that includes a microprocessor and an operating system capable of running applications like word processing and spreadsheets, and has at least 1 GB of memory. Critically, this device must also include the same type of complex antenna system as described in Claim 1, with F21 and F32 values in the same specified ranges.

• Claim 28 details a "multimedia" focused multifunction wireless device. This version of the device includes a receiver for audio signals, a high-quality image recording system (with features like a high-resolution sensor, flash, or zoom), and at least 1 GB of data storage. This claim also requires the inclusion of the specially designed antenna system with the same complexity factor ranges as the other independent claims.

Litigation Status

A search of the U.S. Court of Appeals for the Federal Circuit (CAFC) dockets for 2026 did not reveal any litigation specifically involving US Patent 8,738,103 as of April 30, 2026. However, it's important to note that district court level litigations may exist and would not appear in this specific search. Further investigation into district court records would be required for a comprehensive litigation history.
