Case Timeline

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

U.S. Patent No. 7,333,806 - "System And Method For Enabling Two-Way Radio Communications Over A Computer Network"

• Issued: February 19, 2008

The Invention Explained

• Problem Addressed: The patent’s background section identifies the high cost of conventional long-range two-way radio networks (TWRN), which relied on "audio switching networks or dedicated telephone lines" that required a "costly infrastructure" (’806 Patent, col. 2:35-40).
• The Patented Solution: The invention proposes replacing dedicated lines with a computer network, such as the Internet. In this system, a remote radio sends a unique signal code to a local base station. A controller at that station receives the decoded signal, correlates it to an IP address associated with a distant "target" base station, and establishes a bi-directional communication link over the computer network (’806 Patent, Abstract; col. 3:60-65; Fig. 1). This allows two radios, each connected to a different IP-linked base station, to communicate over long distances.
• Technical Importance: This approach sought to lower the cost of wide-area TWRN by leveraging the widespread and "far more efficient" packet-switched technology of computer networks (’806 Patent, col. 2:41-50).

Key Claims at a Glance

• The complaint asserts at least independent claim 1 (Compl. ¶20, ¶24).
• Independent Claim 1 requires:
  • A first two-way radio with means to select and transmit a signal code.
  • A "shared, public base/repeater station" comprising a decoder and a controller.
  • The controller must be able to receive a decoded signal and correlate it to an internet address of a target base station to establish a "bi-directional computer network link".
  • A target base station with a controller for establishing the link and means for communicating with a second radio.
  • A second two-way radio.
  • A "whereby" clause stating that signals are bi-directionally exchanged between the two radios via the network link between the two station controllers.
• The complaint does not explicitly reserve the right to assert dependent claims.

III. The Accused Instrumentality

Product Identification

• The "Codan Stratus radio system" (the "Accused Product") (Compl. ¶13).

Functionality and Market Context

• The complaint describes the Accused Product as a "system for two-way radio communication" that facilitates communication between two-way radio devices (Compl. ¶13).
• The system is alleged to include base stations/repeaters connected by an IP link, with a "radio internet protocol communication module" used to connect them (Compl. ¶16). It allegedly allows a first two-way radio associated with a first base station to communicate with a second two-way radio associated with a second, "target" base station via this IP link (Compl. ¶14, ¶17-18).
• No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

’806 Patent Infringement Allegations

Identified Points of Contention

• Scope Questions: Claim 1 requires a "shared, public base/repeater station." The complaint does not explain how the accused Codan system, which is likely a commercial or private enterprise system, meets the "public" limitation. A central question may be whether the term "public" has a specific meaning that excludes the Accused Product.
• Technical Questions: The complaint alleges the Accused Product's controller "correlat[es]" a signal to an internet address (Compl. ¶16). The infringement analysis may turn on what evidence is presented to show that the accused "radio internet protocol communication module" performs this specific function as claimed, rather than simply routing pre-configured IP traffic.

V. Key Claim Terms for Construction

The Term: "correlating said decoded signal to one or more internet addresses"

• Context and Importance: This term describes the central logic of the invention: linking a radio-frequency signal code to a network IP address. The outcome of the case could depend on whether the accused system's method of linking repeaters over IP meets this functional requirement. Practitioners may focus on this term because it is the core technical step that enables the invention.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The patent states that the controller "employs a correlation means to correlate the signal to an internet or IP address," without limiting the specific mechanism (’806 Patent, col. 4:58-60). This could support an interpretation covering any method of association.
  • Evidence for a Narrower Interpretation: The specification discloses that this correlation is "preferably ... accomplished by a computer relational database" and may use a "directory means" for referencing a location in that database (’806 Patent, col. 4:10-15; col. 4:60-63). This could support a narrower construction requiring a database lookup or a similar directory-based process.

The Term: "shared, public base/repeater station"

• Context and Importance: The adjectives "shared" and "public" are potential limitations on the type of base station covered by the claims. Defendant may argue its system is private and proprietary, falling outside the scope of a "public" station. The definition of this term could be dispositive for non-infringement.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The patent does not provide an explicit definition for "public," which a plaintiff might argue means it should be given its plain and ordinary meaning, such as being accessible to multiple users, which could describe the accused system.
  • Evidence for a Narrower Interpretation: The term appears without significant elaboration. A defendant could argue that in the context of telecommunications, "public" (as in the "Public Switched Telephone Network," mentioned at col. 2:64) implies a common carrier or publicly accessible utility, which a private commercial radio network is not. The lack of a specific definition in the specification creates ambiguity.

VI. Other Allegations

• Indirect Infringement: The complaint makes no allegations of indirect or induced infringement. It alleges only direct infringement (Compl. ¶22, ¶24).
• Willful Infringement: The complaint alleges Defendant has had "knowledge of infringement of the '806 patent at least as of the service of the present complaint" (Compl. ¶23). This allegation supports a claim for post-suit willfulness only, as it does not plead any facts suggesting Defendant had knowledge of the patent or its alleged infringement prior to the lawsuit's filing. The prayer for relief requests enhanced damages (Prayer for Relief ¶5).

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

• A core issue will be one of definitional scope: can the term "shared, public base/repeater station," which is not explicitly defined in the patent, be construed to cover the Defendant’s commercial radio system? The resolution of this ambiguity in the claim language may be central to the infringement analysis.
• A key evidentiary question will be one of technical operation: does the accused system’s "radio internet protocol communication module" perform the specific function of "correlating" a received radio signal code to an IP address, as required by Claim 1? The case may depend on whether Plaintiff can prove this functional correspondence or if the accused system operates on a different, non-infringing principle for linking its repeaters.
