Case Timeline

II. Technology and Patent(s)-in-Suit Analysis

U.S. Patent No. 9,031,537 - “Electronic wireless hand held multimedia device”

Issued: May 12, 2015

The Invention Explained

• Problem Addressed: The patent asserts that as of its priority date in 2000, handheld devices like Personal Digital Assistants (PDAs) were not available that could "selectively link to more than one wireless connection for purposes of accessing remote multimedia data" from sources like the internet (’537 Patent, col. 2:50-58). Existing devices allegedly lacked the integration of multiple wireless transceiver modules for standards like cellular, 802.11 (WLAN), and short-range protocols in a single unit (’537 Patent, col. 2:58-63).
• The Patented Solution: The invention describes a handheld multimedia device incorporating a microprocessor and, critically, "more than one wireless transceiver modules" that enable communication over a variety of standards, including cellular, WLAN, and short-range protocols like Bluetooth (’537 Patent, Abstract). This architecture is intended to allow a single device to retrieve, process, and display multimedia data (e.g., video, text) from remote servers by connecting to different types of wireless networks (’537 Patent, col. 3:40-49; FIG. 1(c)).
• Technical Importance: The claimed invention addresses the convergence of computing and multi-standard wireless communication in a portable form factor, a key technological trend in the early 2000s that enabled more versatile mobile access to internet content (’537 Patent, col. 2:63-65).

Key Claims at a Glance

• The complaint asserts infringement of "one or more of claims 1-37" (Compl. ¶9). Independent claim 1 is representative.
• Independent Claim 1:
  • An electronic wireless hand held multimedia device, comprising:
  • at least one of a wireless unit and a tuner unit supporting bi-directional data communications of data including video and text... over cellular telecommunications networks, over wireless local area networks and over a direct wireless connection with electronic devices located within short range using Bluetooth communications after accepting a passcode from a user... during the communications;
  • a touch sensitive display screen configured to display the data... by selecting a particular data represented by a soft button on the touch sensitive display screen; and
  • a microprocessor configured to facilitate operation of and communications by the electronic wireless hand held multimedia device.
• The complaint notes that Plaintiff may "limit its claims of infringement to method claims" if necessary to address marking requirements (Compl. ¶13).

III. The Accused Instrumentality

Product Identification

The "Acer Chromebook" is the exemplary accused product (Compl. ¶10).

Functionality and Market Context

The complaint alleges the Acer Chromebook is an "electronic wireless hand held media device[]" that includes a microprocessor and "more than one wireless transceiver modules enabling wireless communications over a variety of standards" (Compl. ¶9). The specific standards alleged to be used by the accused product include Cellular (e.g., 3G), 802.11 (WLAN), and short-range protocols like Bluetooth (Compl. ¶9). The complaint does not provide further technical details on the operation of the accused product.

IV. Analysis of Infringement Allegations

The complaint alleges that the Acer Chromebook infringes because it is a device with a microprocessor and multiple wireless transceivers for communicating over various standards, including cellular, WLAN, and Bluetooth (Compl. ¶9). The complaint states that support for these allegations is found in an "exemplary table included as Exhibit B," but this exhibit is not attached to the filed complaint (Compl. ¶10). The absence of this exhibit precludes a detailed, element-by-element tabular analysis of the infringement allegations.

No probative visual evidence provided in complaint.

V. Key Claim Terms for Construction

The complaint does not provide sufficient detail for a full analysis of potential claim construction disputes. However, based on the asserted claims and the nature of the technology, the following terms may become central to the case.

"accepting a passcode from a user of the electronic wireless hand held multimedia device during the communications" (Claim 1)

• Context and Importance: This limitation appears to require a specific user action ("accepting a passcode") tied to a specific timeframe ("during the communications"). The interpretation of this phrase will be critical for infringement. Practitioners may focus on this term because its construction could determine whether a one-time device login/setup password satisfies the limitation, or if it requires a new passcode for each communication session or for a specific type of secure transaction.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification provides limited specific definition for this phrase, which could support an argument for its plain and ordinary meaning, potentially covering any password entry that enables a wireless connection.
  • Evidence for a Narrower Interpretation: The specification discusses a "security module" for "protected data retrieval and management" and enabling "communications security" (’537 Patent, col. 8:15-19). This context could support an argument that "accepting a passcode" is tied to a specific security function for protecting data, not merely enabling a general network connection.

"hand held multimedia device" (Claim 1)

• Context and Importance: The patent was filed in the era of PDAs and early smartphones, and the specification repeatedly refers to "PDAs," "mobile phones," and "paging device[s]" as examples (’537 Patent, col. 2:8-15, col. 7:60-64). The accused product is an "Acer Chromebook," a laptop computer. Practitioners may focus on this term because the case may hinge on whether a laptop falls within the scope of a "hand held" device as contemplated by the patent.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The term itself is not explicitly limited in the claims, and a party could argue a Chromebook is a portable, multimedia-capable device that can be held in one's hands.
  • Evidence for a Narrower Interpretation: The patent’s consistent examples of PDAs (e.g., "PalmPilot," "Handspring Visor") and its focus on devices designed for use "on the go" could support a narrower construction limited to smaller, smartphone-like devices and excluding laptops (’537 Patent, col. 2:10-18).

VI. Other Allegations

• Indirect Infringement: Plaintiff explicitly "reserves the right to amend to add claims for indirect infringement" pending discovery (Compl. ¶11, fn. 1). No specific facts supporting inducement or contributory infringement are currently alleged.
• Willful Infringement: Plaintiff reserves the right to amend to add a claim for willful infringement "to the extent fact discovery shows Defendant's pre-expiration knowledge of the patent" (Compl. ¶11, fn. 1). The complaint does not currently allege any facts to support pre-suit knowledge or willfulness.

VII. Analyst’s Conclusion: Key Questions for the Case

1. A central issue will be one of claim scope: can the term "hand held multimedia device," which the patent specification consistently associates with PDAs and mobile phones from the year 2000, be construed to cover a modern laptop like the accused "Acer Chromebook"?
2. A key evidentiary question will be one of technical satisfaction: does the standard operation of an Acer Chromebook meet the specific limitation of "accepting a passcode from a user... during the communications," or is this a functional step not performed by the accused product in the manner required by the claim?
3. The case may also present a procedural question regarding damages: has the Plaintiff, a self-identified non-practicing entity, satisfied the marking requirements of 35 U.S.C. § 287(a) through its handling of prior settlement licenses, or will its ability to collect pre-suit damages be limited?
