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

U.S. Patent No. 8,205,622 - "Electronic Cigarette"

• Patent Identification: U.S. Patent No. 8,205,622, "Electronic Cigarette," issued June 26, 2012.

The Invention Explained

• Problem Addressed: The patent’s background section describes prior art electronic cigarettes as being overly complex, costly, and suffering from technical problems including liquid leakage and "discontinuous vaporizing" ('622 Patent, col. 2:7-9). It specifically identifies a key drawback as the use of "mechanical devices as an airflow detector, which has a short life and is too sensitive to outside temperature and humidity changes" ('622 Patent, col. 2:10-12).
• The Patented Solution: The invention is an electronic cigarette, preferably comprising a detachable "electronic inhaler" and "electronic atomizer" ('622 Patent, col. 2:27-30). To solve the sensor problem, it employs an "electric airflow sensor" that detects a user's puff and sends a signal to a "Single Chip Micyoco" (a microcontroller) ('622 Patent, col. 2:47-54). This chip then instructs the power source to heat a liquid solution for a specific duration and intensity, creating a vapor that "closely mimics the process of cigarette smoking" ('622 Patent, col. 4:29-32).
• Technical Importance: The use of an electric sensor and a microcontroller sought to provide a more reliable and responsive activation mechanism compared to the mechanical switches used in earlier devices ('622 Patent, col. 3:37-43).

Key Claims at a Glance

• The complaint identifies independent claim 13 as being infringed (Compl. ¶29).
• The essential elements of independent claim 13 are:
  • An electronic cigarette comprising a tubular electronic inhaler and a tubular electronic atomizer.
  • The electronic inhaler includes an electric power source that provides an electric current to the electronic atomizer.
  • The electronic cigarette further comprises an electric airflow sensor used to turn on and off the power source by detecting airflow and sending a signal to a "Single Chip Micyoco."
  • The Single Chip Micyoco receives the signal from the airflow sensor.
  • The Single Chip Micyoco instructs the electric power source to send an electric current to the atomizer.
  • The Single Chip Micyoco also instructs "a time period and a magnitude of the electric current."
• The complaint alleges infringement of "one or more claims," preserving the right to assert additional claims (Compl. ¶19).

III. The Accused Instrumentality

Product Identification

• The complaint names the "SIDE BAE" electronic cigarette and other "substantially similar" products sold by the Defendant (Compl. ¶¶15, 20).

Functionality and Market Context

• The SIDE BAE is described as an electronic cigarette containing a rechargeable battery that functions as a power source, an "electric airflow sensor to detect air movement," and an electronic atomizer (Compl. ¶¶16-17). The complaint alleges that when a user inhales through the device's "air-puffing hole," it creates an "air inflow, which triggers the atomization process that converts a solution to a gas emulating the smoking process" (Compl. ¶18). The complaint does not provide further details on the product's market positioning.

IV. Analysis of Infringement Allegations

The complaint alleges that it attaches a claim chart as Exhibit 2, but this exhibit was not included with the filed document (Compl. ¶29). Therefore, the infringement theory is summarized below in prose based on the complaint's narrative allegations.

No probative visual evidence provided in complaint.

The complaint alleges that the accused SIDE BAE product infringes at least claim 13 of the '622 Patent. The infringement theory appears to map the product's basic components directly onto the claim's elements. The complaint asserts that the SIDE BAE product is an electronic cigarette with an inhaler and atomizer structure (Compl. ¶¶16-17), satisfying the claim's preamble. It further alleges the product contains a rechargeable battery (the "electric power source") (Compl. ¶16), an "electric airflow sensor" (Compl. ¶16), and an atomizer with a heating element (Compl. ¶17). The core of the infringement allegation is that user inhalation is detected by this sensor and "triggers the atomization process" (Compl. ¶18), which the plaintiff contends meets the claim requirements of detecting airflow, signaling a controller, and activating the heating element.

• Identified Points of Contention:
  • Scope Question: A potential dispute may arise over the term "Single Chip Micyoco." The court may need to determine if this term, as used in the patent, is limited to a specific type of component or can be construed more broadly to cover any generic microcontroller or CPU that may be present in the accused device.
  • Technical Question: Claim 13 requires the "Single Chip Micyoco" to instruct not only that a current be sent, but also to instruct a specific "time period and a magnitude of the electric current." The complaint alleges that inhalation "triggers the atomization process" (Compl. ¶18) but does not provide specific facts on how, or if, the accused device's circuitry controls the duration and magnitude of the electrical current. The case may turn on whether the accused device's controller performs these specific claimed functions or operates as a simple on/off switch activated by airflow.

V. Key Claim Terms for Construction

• The Term: "Single Chip Micyoco"

• Context and Importance: This term appears to be a neologism or a transliteration and is central to the control element of claim 13. Its construction is critical because it will define what type of processing unit can be found to infringe. Practitioners may focus on this term to dispute whether the specific controller in the accused product meets this limitation.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification describes this component functionally as a processor that executes "embedded computer programs" to control the power source based on a signal from the sensor ('622 Patent, col. 4:18-22). This could support an interpretation that the term simply means any single-chip microcontroller capable of performing the claimed functions.
  • Evidence for a Narrower Interpretation: The repeated and specific use of the unique phrase "Single Chip Micyoco," rather than a standard term like "microprocessor" or "controller" (which are used elsewhere in the patent), could suggest that the inventor intended to claim a particular type of component, potentially narrowing the claim's scope.

• The Term: "instructs . . . a time period and a magnitude of the electric current"

• Context and Importance: This functional language defines how the controller must interact with the power source. Infringement requires more than a simple activation; it requires specific control over the current's duration and strength. The viability of the infringement claim may depend heavily on whether the accused device's functionality meets this specific requirement.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification mentions supplying an electric current for a "predefined time length" ('622 Patent, col. 2:57-58), which might be interpreted as a simple, fixed duration rather than a dynamically calculated one.
  • Evidence for a Narrower Interpretation: The patent explicitly states that the "magnitude of the electric current... depends on the magnitude of signal detected from the airflow proportional to the strength of user's puffing action" ('622 Patent, col. 4:26-30). This language suggests a more sophisticated, variable control scheme and could support a narrower construction requiring the device to modulate power based on inhalation strength.

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement, stating that the Defendant has been "requesting and encouraging and inducing customers to purchase and use SIDE BAE" in an infringing manner (Compl. ¶33). The complaint does not plead specific facts, such as references to user manuals or advertising, to support the element of intent.
• Willful Infringement: Willfulness is alleged based on the assertion that "defendant had knowledge of the '622 Patent" at all relevant times (Compl. ¶21). The complaint does not state the basis for this alleged pre-suit knowledge.

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

• A core issue will be one of definitional scope: can the idiosyncratic term "Single Chip Micyoco," as defined by the patent's specification, be construed to read on the control circuitry used in the accused "SIDE BAE" product, or is it limited to a more specific type of component?
• A key evidentiary question will be one of functional operation: does the Plaintiff have evidence that the accused device performs the specific function of instructing a power source concerning the "time period and a magnitude of the electric current," as required by Claim 13, or does the device's circuitry simply function as an on/off switch activated by airflow, potentially creating a mismatch with the claim language?
