Case Timeline

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

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

The Invention Explained

• Problem Addressed: The patent describes a technical landscape around the year 2000 where Personal Digital Assistants (PDAs) were popular but had limited wireless capabilities, typically restricted to a single wireless connection type (e.g., infrared or a single cellular standard) and lacked robust multimedia processing features like video playback ('537 Patent, col. 2:50-63). There was a recognized need for a single device that could connect to various disparate wireless networks to access remote multimedia data sources ('537 Patent, col. 2:63-65).
• The Patented Solution: The invention proposes a handheld electronic device that integrates a microprocessor with "more than one wireless transceiver modules" to enable communication over a variety of standards, such as cellular (GSM, CDMA), WLAN (802.11), and short-range (Bluetooth, Infrared) networks ('537 Patent, Abstract; col. 4:37-46). This multi-modal communication capability is combined with features like a touch-sensitive display for multimedia, GPS for mapping, a camera, and mobile payment modules, creating a converged multimedia device ('537 Patent, Abstract; Fig. 1(b)).
• Technical Importance: The claimed invention addresses the early-stage convergence of computing, telecommunications, and multimedia into a single, portable form factor, predating the widespread commercialization of modern smartphones.

Key Claims at a Glance

The complaint asserts infringement of claims 1-37 (Compl. ¶8). Independent claim 1 is representative and recites:

• at least one of a wireless unit and a tuner unit supporting bi-directional data communications of data including video and text for the electronic wireless hand held multimedia device with remote data resources 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 of the electronic wireless hand held multimedia device during the communications;
• a touch sensitive display screen configured to display the data including video and text received by the electronic wireless hand held multimedia device by selecting a particular data represented by a soft button on the touch sensitive display screen of the electronic wireless hand held multimedia device; and
• a microprocessor configured to facilitate operation of and communications by the electronic wireless hand held multimedia device.

III. The Accused Instrumentality

Product Identification

The complaint broadly accuses Defendant’s "systems, products, and services," including an "electronic wireless hand held multimedia device" (Compl. ¶8, ¶10).

Functionality and Market Context

The complaint does not identify any specific Razer product or service by name. It provides no details regarding the functionality, features, or operation of the accused instrumentalities beyond the conclusory allegation that they practice the claimed inventions (Compl. ¶8).

IV. Analysis of Infringement Allegations

The complaint does not provide specific factual allegations detailing how the accused products infringe the ’537 Patent. Instead, it states that "Support for the allegations of infringement may be found in the the chart attached as exhibit B" (Compl. ¶9). This exhibit was not included with the complaint document provided. The complaint contains only general allegations that Defendant’s products and services infringe one or more claims of the ’537 patent, literally or under the doctrine of equivalents (Compl. ¶8).

No probative visual evidence provided in complaint.

Identified Points of Contention

Given the generality of the complaint and the 2000 priority date of the patent, several points of contention may arise.

• Scope Questions: A central question will be whether the specific architecture described in the ’537 Patent, conceived in the context of early PDAs, reads on the design of modern electronic devices. For example, does the claimed "wireless unit and a tuner unit" map onto the integrated, multi-band, software-defined radio chipsets used in contemporary products?
• Technical Questions: A key factual dispute may involve the claim limitation "after accepting a passcode from a user...during the communications." The complaint does not explain how any accused product performs this specific authentication sequence in connection with establishing a Bluetooth connection as part of a broader communication session involving cellular and WLAN networks.

V. Key Claim Terms for Construction

"at least one of a wireless unit and a tuner unit" (Claim 1)

• Context and Importance: This term defines the core communication hardware of the claimed device. Its construction will be critical to determining whether the patent's scope can cover modern, highly integrated wireless transceivers (e.g., System-on-a-Chip designs) that did not exist when the patent was filed. Defendant may argue this term refers to the discrete, separate components common in the year 2000, while Plaintiff may argue for a broader, functional definition.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The patent repeatedly refers to "wireless transceiver modules" in the plural and depicts them as a single block ("RF WIRELESS TRANSCEIVER MODULES" 17) in a high-level schematic, which could suggest a functional rather than a strictly structural grouping ('537 Patent, Fig. 1(b)).
  • Evidence for a Narrower Interpretation: The detailed description discusses configuring separate transceivers for different communication standards, such as a "first wireless transceiver module 17a," a "second wireless transceiver module 17b," and so on, which could support a construction requiring distinct hardware units for each communication type ('537 Patent, col. 6:56-65; Fig. 1(c)).

"selecting a particular data represented by a soft button on the touch sensitive display screen" (Claim 1)

• Context and Importance: This term relates to the user interface for interacting with received data. The dispute may center on whether this requires a specific type of user interface element (a "soft button") to be directly associated with a "particular data" element for selection, or if it can be read more broadly to cover any touch-based interaction on a modern graphical user interface that results in data selection.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The specification describes the display screen as having "icons 33 operable as soft buttons providing options and action," suggesting a functional definition where an icon acts as a button ('537 Patent, col. 5:45-48).
  • Evidence for a Narrower Interpretation: The patent's figures from the relevant era depict a user interface with discrete, clearly demarcated icons for specific applications (e.g., "Phone," "Email," "WWW"), which may be argued to limit the term's scope to such an arrangement, as opposed to more fluid, gesture-based modern interfaces ('537 Patent, Fig. 1(a)).

VI. Other Allegations

Indirect Infringement

The complaint alleges both induced and contributory infringement. It asserts that Defendant actively encourages or instructs customers on how to use its products in an infringing manner and that the products have no substantial non-infringing uses (Compl. ¶10, ¶11).

Willful Infringement

Willfulness allegations are based on knowledge of the ’537 Patent "from at least the filing date of the lawsuit" (Compl. ¶10, ¶11). This frames the allegation as one of post-suit willfulness. The complaint explicitly reserves the right to amend to allege pre-suit knowledge if discovered later (Compl. ¶10, fn. 1).

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

• A core issue will be one of temporal scope: Can claim terms drafted in 2000 to describe the nascent convergence of PDAs and multi-modal wireless technology be construed to cover the features and integrated architecture of modern electronic devices, or are they limited to the specific technological implementations of that earlier era?
• A key evidentiary question will be one of specificity: Given the complaint’s lack of detail, a primary issue for pre-trial discovery will be for the Plaintiff to identify the specific accused products and articulate a plausible, element-by-element infringement theory, particularly since the complaint's factual support rests entirely on an unprovided exhibit.
• A central legal and technical question will be the interpretation of function: Does the accused device's user authentication for Bluetooth pairing and its method of data selection via a touch interface perform the same function, in substantially the same way, to achieve the same result as the specific sequence and "soft button" structure required by the patent's claims?
