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

U.S. Patent No. 7,614,402 - "Simulated Cigarette"

• Patent Identification: U.S. Patent No. 7,614,402, "Simulated Cigarette", issued November 10, 2009 (the "’402 Patent").

The Invention Explained

• Problem Addressed: The patent identifies a need for a smoking cessation aid that addresses not only nicotine addiction but also the "oral fixation" smokers must overcome, describing prior art as either retaining the "unpleasant taste and odor of a cigarette" or requiring actual smoking, which poses a fire hazard (’402 Patent, col. 1:18-32).
• The Patented Solution: The invention is a non-combustible, simulated cigarette that mimics the look and feel of a real cigarette but contains a flavoring agent (e.g., mint) within a hollow portion of its filter. When a user applies pressure, the flavor is dispersed into the user's mouth, satisfying the craving without smoke or nicotine (’402 Patent, Abstract; col. 2:37-53). A cut-away view in Figure 2 illustrates the core components, showing the flavoring means (25) inside a hollow portion (24) within the filter member (22) (’402 Patent, Fig. 2).
• Technical Importance: The invention offers a smoke-free, healthy replacement for the physical act of smoking that also provides a "fresh, mint taste," targeting the behavioral and sensory aspects of cigarette cravings (’402 Patent, col. 1:35-39).

Key Claims at a Glance

• The complaint asserts independent Claim 1 (’402 Patent, col. 4:21-42; Compl. ¶11).
• The essential elements of Claim 1 are:
  • A simulated cigarette for use as a smoking cessation aid, comprising:
  • (a) a cylindrical member having a predetermined size and shape, said cylindrical member having a first and second portion;
  • (b) a filter member formed at an end of said first portion of said cylindrical member, said filter member having a predetermined size and shape capable of being comfortably held between a user's lips;
  • (c) an opening within an end of said filter member;
  • (d) a hollow portion formed within said filter member; and
  • (e) a flavoring means placed within said hollow portion, said flavoring means capable of dispersing flavoring through said opening of said filter member and into a user's mouth upon the application of pressure to said filter member to aid in the reduction of a user's urge for a cigarette;
  • wherein said hollow portion comprises a plastic tube which extends through said filter member for containing said flavoring means therein.
• The prayer for relief seeks judgment that Defendant has infringed "one or more claims," which may suggest an intent to assert other claims, including dependent claims, later in the litigation (Compl. p. 3).

III. The Accused Instrumentality

Product Identification

• The complaint identifies "cigarette-like devices under the 'FUM Disposables' brand" as the Accused Product (Compl. ¶11).

Functionality and Market Context

• The complaint provides limited technical detail, describing the Accused Product only as "cigarette-like devices" (Compl. ¶11). It makes a conclusory allegation that the product "includes, without limitation, all of the elements claimed in claim 1 of the '402 Patent" but does not describe how the product operates or what specific features correspond to the claim elements (Compl. ¶12). The complaint does not provide specific allegations regarding the product's commercial importance.

IV. Analysis of Infringement Allegations

The complaint references a claim chart attached as Exhibit B, which was not included in the provided filing (Compl. ¶13). The following table summarizes the infringement allegations based on the recitation of Claim 1 in the complaint body and the general allegation that the Accused Product meets every element.

• ’402 Patent Infringement Allegations

Claim Element (from Independent Claim 1)	Alleged Infringing Functionality	Complaint Citation	Patent Citation
A simulated cigarette for use as a smoking cessation aid... comprising: (a) a cylindrical member having a predetermined size and shape...	The complaint alleges the Accused Product is a "cigarette-like device" with this structure.	¶11, ¶12	col. 2:39-40
(b) a filter member formed at an end of said first portion of said cylindrical member, said filter member having a predetermined size and shape capable of being comfortably held between a user's lips;	The complaint alleges the Accused Product contains a filter member with these characteristics.	¶12	col. 2:42-45

wherein said hollow portion comprises a plastic tube which extends through said filter member for containing said flavoring means therein.	The complaint alleges the Accused Product contains this element.	¶12	col. 3:10-14

• Identified Points of Contention:
  • Evidentiary Questions: The complaint's infringement theory is pleaded with minimal factual support. A central issue will be whether discovery reveals evidence that the FUM Disposables product actually contains the specific structures required by Claim 1, particularly a "plastic tube" containing a "flavoring means."
  • Technical Questions: A key question is how the accused device releases flavor. The claim requires flavor dispersion "upon the application of pressure." The complaint does not specify whether this occurs via squeezing, inhalation, or another mechanism in the accused product, leaving the specific mechanism of infringement unclear.

V. Key Claim Terms for Construction

• The Term: "flavoring means"

• Context and Importance: This term is recited in means-plus-function format under 35 U.S.C. § 112(f). The recited function is "dispersing flavoring... upon the application of pressure." The scope of infringement will depend entirely on the structure(s) disclosed in the specification that perform this function and their equivalents.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification describes multiple structures, which could support a broader construction. It discloses that the flavoring means can be a "liquid," "tablet or powder" (col. 3:22-29). It also states that the "application of pressure" can be "external pressure... via the user's lips or hands" or "the application of a vacuum, or inhalation" (col. 3:15-21).
  • Evidence for a Narrower Interpretation: A defendant may argue that the corresponding structure is limited to the specific embodiments shown, such as the flavoring (25) contained within the plastic tube (34) as depicted in Figure 2 (’402 Patent, Fig. 2; col. 3:10-14).

• The Term: "application of pressure"

• Context and Importance: This term is critical to the mechanism of infringement. Practitioners may focus on this term because its definition—whether it is limited to external compression or also includes suction—will determine what types of devices can infringe.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification explicitly states that the pressure can be applied in multiple ways: "One technique can include the application of an external pressure to the filter member... Another technique can include the application of a vacuum, or inhalation..." (col. 3:15-21).
  • Evidence for a Narrower Interpretation: A party might argue that in the context of the entire claim, which does not recite airflow channels, the term should be limited to the more direct meaning of applying external physical force, as squeezing a tube is a more intuitive way to disperse its contents than inhaling from it.

VI. Other Allegations

• Indirect Infringement: The complaint includes a prayer for relief for induced infringement but does not plead any specific underlying facts, such as the existence of instructional materials or advertisements, to support the required element of intent (Compl. p. 3).
• Willful Infringement: The complaint alleges that the infringement "has been and is willful and deliberate" (Compl. ¶14). It does not, however, allege any facts to support pre-suit knowledge of the ’402 Patent, such as a prior cease-and-desist letter or other communication.

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

• A primary issue will be one of evidence: given the conclusory nature of the infringement allegations, can the Plaintiff produce factual evidence demonstrating that the "FUM Disposables" product incorporates each specific claimed element, most notably the internal "plastic tube" containing a pressure-released "flavoring means"?
• The case will likely turn on a question of claim construction: what is the proper scope of the means-plus-function term "flavoring means"? The court's determination of the corresponding structure disclosed in the patent will be critical to the infringement analysis.
• A third key question relates to substantiation of ancillary claims: can the Plaintiff develop facts through discovery to support its currently un-pled allegations of induced and willful infringement, which require showing Defendant's knowledge and specific intent?
