Case Timeline

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

U.S. Patent No. 8,337,239, "Hardened micro SIM adaptor" (Issued Dec. 25, 2012)

The Invention Explained

• Problem Addressed: The patent identifies a need for an adaptor to allow newer, smaller micro SIM cards to be used in devices designed for the older, larger mini SIM card format. It notes that simple plastic adaptors can be damaged by the high levels of internal heat generated by a phone's battery, which is often located adjacent to the SIM card tray (’239 Patent, col. 1:48-58).
• The Patented Solution: The invention is a frame-like adaptor shaped like a mini SIM card with a cutout region configured to receive and hold a micro SIM card. A key aspect of the solution is the material composition; the adaptor body is made of a heat-resistant material such as plastic, nylon, aluminum, or carbon fiber that is "capable of withstanding heat levels up to at least about 250° Fahrenheit without degradation" (’239 Patent, col. 4:56-60; Abstract). Certain embodiments include a "floor" to support the micro SIM card within the cutout (’239 Patent, col. 2:62-63).
• Technical Importance: The invention provided a durable solution to the practical problem of SIM card interoperability, allowing users to move a single SIM card between new and old devices without concern for the adaptor failing due to heat.

Key Claims at a Glance

• The complaint asserts at least independent claim 1 (Compl. ¶15).
• The essential elements of independent claim 1 are:
  • An adaptor for allowing use of a micro SIM card in a device using mini SIM cards, comprising:
  • an adaptor body having a cutout region defined by walls in the adaptor, said cutout region shaped to receive a micro SIM card therein;
  • a floor on said cutout region for supporting the micro SIM card therein; and
  • said adaptor body made of plastic and/or nylon, carbon fiber, aluminum, or similar material capable of withstanding heat levels up to at least about 250° Fahrenheit without degradation.
• The complaint reserves the right to assert other claims by alleging infringement of "one or more claims" (Compl. ¶15).

U.S. Patent No. 8,573,986, "SIM card adaptor" (Issued Nov. 5, 2013)

The Invention Explained

• Problem Addressed: Expanding on the problem solved by its parent patent, the ’986 Patent addresses the broader challenge of adapting any smaller format SIM card (such as micro or nano) for use in an electronic device built for a larger format SIM card (such as mini or micro) (’986 Patent, col. 1:27-33). It again highlights the risk of heat from the device's battery damaging a conventional adaptor (’986 Patent, col. 1:51-59).
• The Patented Solution: The solution is a generic, heat-resistant adaptor body sized for a larger SIM format, with a cutout shaped to receive a smaller SIM format. The core innovation remains the use of a material—"plastic and/or nylon, carbon fiber, aluminum, or similar material"—capable of withstanding high temperatures, specified in the claims as "at least about 200° Fahrenheit without degradation" (’986 Patent, col. 2:9-13; Abstract).
• Technical Importance: As the industry continued to adopt even smaller SIMs (e.g., the nano SIM), this invention offered a generalized and durable solution for ensuring backward compatibility across a growing matrix of device and SIM card combinations.

Key Claims at a Glance

• The complaint asserts at least independent claim 1 (Compl. ¶26).
• The essential elements of independent claim 1 are:
  • A SIM card adaptor for allowing use of a smaller format SIM card in an electronic device using a larger format SIM card, comprising:
  • a. an adaptor body having a cutout region defined by walls in the adaptor, the cutout region shaped to receive the smaller format SIM card therein; and
  • b. the adaptor body sized and shaped for use in the electronic device using the larger format SIM card, and wherein the adaptor body comprises plastic and/or nylon, carbon fiber, aluminum, or similar material capable of withstanding heat levels up to at least about 200° Fahrenheit without degradation.
• The complaint reserves the right to assert other claims (Compl. ¶26).

III. The Accused Instrumentality

Product Identification

The "Exemplary Mint Mobile Products" are identified as "Mobile's Starter Kit 3-in-1 SIM Card" (Compl. ¶15, ¶1).

Functionality and Market Context

The accused product is a single card from which a user can punch out a Standard (mini), Micro, or Nano-sized SIM. By its design, the remaining plastic frame can function as an adaptor to fit a smaller, punched-out SIM into a device requiring a larger size (Compl. ¶15, ¶26). These "3-in-1" cards are a common method for mobile operators to provide a universal SIM solution compatible with nearly all phones. The complaint alleges that these products are made from a material that maintains its shape at high temperatures and that they are sold as part of a "Starter Kit," placing them at the center of Defendant's customer acquisition strategy (Compl. ¶12, ¶15).

IV. Analysis of Infringement Allegations

The complaint references, but does not include, claim chart exhibits (Compl. ¶21, ¶30). The following tables summarize the infringement allegations for the lead asserted claim of each patent based on the complaint's narrative theory that the accused products "satisfy all elements" of the claims (Compl. ¶20, ¶29).

No probative visual evidence provided in complaint.

'239 Patent Infringement Allegations

'986 Patent Infringement Allegations

• Identified Points of Contention:
  • Structural Questions: A primary dispute regarding the '239 Patent may concern whether the accused 3-in-1 punch-out frame has a structure that meets the "floor" limitation of claim 1.
  • Technical Questions: A key factual question for both patents is whether the specific plastic used in Defendant's 3-in-1 SIM cards can actually withstand the claimed temperatures (250°F for the '239 patent; 200°F for the '986 patent) "without degradation." This will likely require expert testimony and material testing.
  • Scope Questions: The case may raise the question of whether a disposable punch-out frame, which is part of the product's initial packaging, constitutes an "adaptor" in the reusable sense described in the patents' background sections.

V. Key Claim Terms for Construction

• The Term: "a floor" ('239 Patent, Claim 1)

  • Context and Importance: This term is a specific structural limitation of the asserted '239 claim. Infringement will depend on whether the accused product, a thin plastic frame, is found to possess a "floor." Practitioners may focus on this term because a simple frame structure may not satisfy a narrow construction of "floor," potentially offering a path to non-infringement.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The patent states "a floor support 17 supports the micro SIM card therein" (’239 Patent, col. 2:62-63). A party could argue that any structure, even a thin perimeter ledge, that "supports" the card and prevents it from falling through meets the functional requirement of a floor.
    • Evidence for a Narrower Interpretation: Figure 1 of the patent depicts the "floor support 17" as a distinct, solid surface that spans the bottom of the cutout region. A party could argue that "floor" requires such a continuous bottom surface, not merely the edge of an open frame.

• The Term: "without degradation" ('239 Claim 1, '986 Claim 1)

  • Context and Importance: This term defines the performance standard for the claimed heat resistance. The infringement analysis will turn on how much, and what kind of, material change constitutes "degradation."
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: In its examples, the patent contrasts passing results ("no signs of wear, melting, peeling," "no melting, smoldering or other damage") with failure, suggesting "degradation" implies a loss of structural or functional integrity (’239 Patent, col. 4:9-10, col. 4:27-28).
    • Evidence for a Narrower Interpretation: The patent describes an experiment where, at 400°F, "discoloration to a light yellow/brown color was observed" but "no smoldering or melting observed" (’239 Patent, col. 4:36-38). A party could argue that this discoloration is itself a form of "degradation," setting a high bar that prohibits any permanent physical or chemical change.

VI. Other Allegations

• Indirect Infringement: The complaint alleges both induced and contributory infringement for both patents. The factual basis for these claims is the act of selling the 3-in-1 SIM cards to customers for use in their cellular devices, as well as distributing "product literature and website materials" that allegedly instruct users on how to use the products in an infringing manner (Compl. ¶17-19, ¶26-28).
• Willful Infringement: While the complaint does not use the word "willful," it puts Defendant on notice by stating that the filing of the complaint constitutes "actual knowledge" of the patents and that any subsequent infringement is done despite this knowledge (Compl. ¶16, ¶25). Plaintiff requests that the case be declared "exceptional" under 35 U.S.C. § 285, which provides a basis for seeking enhanced damages and attorneys' fees for post-suit conduct (Compl. p. 9, ¶i).

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

• A core issue will be one of structural interpretation: can the perimeter frame of the accused 3-in-1 punch-out card be construed to meet the "floor" limitation of '239 Patent's Claim 1, or is there a fundamental structural mismatch?
• A key evidentiary question will be one of material performance: does the plastic used in Defendant's SIM cards verifiably withstand the 200°F and 250°F temperatures claimed in the patents "without degradation," a determination that will hinge on expert testing and the court's definition of that term?
• The case may also present a question of definitional scope: does a disposable punch-out frame, which is part of the product's packaging, fall within the scope of the term "adaptor" as contemplated by the patents, which describe a device for promoting interoperability and reuse?
