I. Executive Summary and Procedural Information

• Parties & Counsel:
  • Plaintiff: ProudLion IP, LLC (Texas)
  • Defendant: Montblanc North America, LLC (Delaware)
  • Plaintiff’s Counsel: Ramey, LLP
• Case Identification: 4:23-cv-02050, S.D. Tex., 12/22/2023
• Venue Allegations: Plaintiff alleges venue is proper because Defendant has a regular and established place of business in the district, has committed acts of infringement in the district, and conducts substantial business in Texas.
• Core Dispute: Plaintiff alleges that Defendant’s smartwatches, which operate on the Wear OS platform, infringe a patent related to methods for simultaneously altering the appearance and operational parameters of a portable computing device.
• Technical Context: The technology concerns the user interface (UI) and user experience (UX) on portable electronic devices, allowing users to create and apply custom profiles for different environmental conditions (e.g., adjusting screen brightness, fonts, and notification types for a dark or quiet setting).
• Key Procedural History: The complaint notes that the patent-in-suit issued after the Supreme Court's decision in Alice Corp. v. CLS Bank, and cites the patent examiner's statement of allowability, framing the invention as a patent-eligible "improved user interface." This suggests Plaintiff anticipates and is preemptively addressing a patent eligibility challenge under 35 U.S.C. § 101.

Case Timeline

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

U.S. Patent No. 9,967,389 - "System And Method For Selectable Alteration Of Operation And Appearance Of A Portable Computing Device"

The Invention Explained

• Problem Addressed: The patent describes conventional mobile devices as potentially "obtrusive" in certain situations, such as a "darkened environment, where silence is expected or needed" (’389 Patent, col. 1:39-42). It further notes the need for users to personalize device settings beyond pre-loaded profiles, even when the device lacks network connectivity (’389 Patent, col. 1:50-56).
• The Patented Solution: The invention is an application on a portable device that allows a user to create a custom "skin" or profile by simultaneously altering multiple operational and appearance parameters. This includes changing the backlight, font, and frequency mode (e.g., audio vs. haptic feedback), as well as aggregating various applications (email, messaging, social networks) for display on a single screen (’389 Patent, Abstract; col. 2:3-23). The process is initiated and confirmed by the user through a series of interactions with "actuation objects" on the device's touchscreen.
• Technical Importance: The claimed invention purports to provide a technological improvement by allowing a user to "easily adjust the appearance and/or operation of a portable computing device" to suit specific, user-defined environmental needs, rather than relying on predefined system modes (Compl. ¶15).

Key Claims at a Glance

• The complaint asserts claims 1-20, with a focus on independent claim 1 (Compl. ¶¶ 3, 21).
• Independent Claim 1 of the ’389 Patent requires:
  • A system comprising a portable computing device with a touch screen display, variable lighting module, frequency alteration module, processor, and non-volatile memory.
  • The processor is configured to execute instructions to perform a sequence of steps:
    • receive a first mode alteration request using a first actuation object;
    • selectably aggregate a plurality of email applications;
    • selectably aggregate a plurality of messaging systems;
    • selectably aggregate a plurality of social network applications;
    • selectably alter backlight level;
    • selectably alter font;
    • selectably alter frequency mode;
    • accept at least one of the alterations and aggregations using a second actuation object; and
    • implement the mode alteration using a third actuation object.

III. The Accused Instrumentality

Product Identification

• The complaint identifies "Montblanc's smart watches" and, more specifically, the "Wear OS" operating system as the Accused Instrumentality (Compl. ¶¶ 3, 22).

Functionality and Market Context

• The complaint alleges that Defendant "maintains, operates, and administers systems and methods that selectably alter the operation and appearance of a portable computing device" in a way that infringes the ’389 Patent (Compl. ¶21). The allegations suggest that the accused functionality is inherent in the standard operation of the Wear OS platform on Defendant's smartwatches, which allows users to customize device settings and manage notifications from various applications.

IV. Analysis of Infringement Allegations

The complaint references a preliminary infringement chart in "Exhibit B," which was not attached to the filed document (Compl. ¶22). The infringement theory must therefore be constructed from the narrative allegations. No probative visual evidence provided in complaint.

’389 Patent Infringement Allegations

Identified Points of Contention

• Technical Question: The complaint provides no specific evidence detailing how the accused Wear OS performs the claimed functions. A central issue will be whether the standard functionality of Wear OS—such as adjusting settings in a menu or viewing a list of notifications—maps to the specific, multi-step process required by claim 1. For example, does Wear OS perform a function that can be fairly characterized as "aggregating" applications, or does it merely display notifications from them?
• Scope Question: The claim requires a specific sequence involving three distinct "actuation objects." The case may turn on whether routine UI interactions in Wear OS (e.g., opening a settings menu, adjusting a slider, and tapping "apply") can be parsed into the "first," "second," and "third" actuation objects as claimed, or if the patent requires a more specialized, integrated workflow not present in the accused system.

V. Key Claim Terms for Construction

• The Term: "actuation object"

  • Context and Importance: This term appears three times in independent claim 1, forming the structural backbone of the claimed method (request, accept, implement). Its construction is critical because infringement will depend on finding three separate, corresponding user interactions in the accused Wear OS. Practitioners may focus on this term to determine if it is limited to the specific "launcher" icon shown in the patent or if it can broadly cover any UI element that initiates a function.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The term itself is generic. The specification states an actuation object can be an "application launcher object 101" (’389 Patent, col. 4:56-59) but also refers to a "sub menu icon" as a potential actuation object (’389 Patent, col. 17:7-9), suggesting it is not limited to a single type of UI element.
    • Evidence for a Narrower Interpretation: The complaint itself defines the term by citing a specific passage: "An actuation object is the launcher on the touchscreen display to alter operating characteristics on the portable device" (Compl. ¶8, citing ’389 Patent, col. 4:52-54). Defendant may argue this constitutes a narrow definition. The patent figures consistently depict distinct icons or buttons for these actions (e.g., '389 Patent, Fig. 1B, objects 110, 120, 130).

• The Term: "selectably aggregate"

  • Context and Importance: This term is used for email, messaging, and social network applications. The viability of the infringement claim depends on whether the accused Wear OS performs this "aggregation." A narrow definition might require creating a single, custom screen displaying icons for the selected apps, while a broad definition could cover a simple unified notification stream.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The term "aggregate" itself can mean simply to "collect or gather into a whole." This could arguably read on a unified notification inbox or a screen that shows alerts from multiple application types.
    • Evidence for a Narrower Interpretation: The complaint offers a definition from the patent: "To selectively aggregate a plurality of social network applications is to display in a single screen with a selected order each aggregated application" (Compl. ¶5, citing ’389 Patent, col. 5:31-37). The specification further clarifies that implementing the aggregation "can comprise displaying object(s) corresponding to each email application, each messaging system, and each social network application on the touchscreen display in a single screen with selectable order" (’389 Patent, col. 5:30-37). This language, along with Figure 3, suggests a specific function of creating a user-curated list of application objects, not just viewing their outputs.

VI. Other Allegations

• Indirect Infringement: The complaint makes boilerplate allegations of induced and contributory infringement, stating Defendant "actively encouraged or instructed others" to use the products in an infringing manner and that there are "no substantial noninfringing uses" (Compl. ¶¶ 23, 24). No specific factual support, such as references to user manuals or marketing materials, is provided.
• Willful Infringement: Willfulness is alleged based on Defendant’s knowledge of the ’389 patent "from at least the filing date of the lawsuit" (Compl. ¶¶ 23, 24). This allegation appears to be based only on post-suit knowledge.

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

1. A question of definitional scope: Can the specific, three-step "request, accept, implement" process, each tied to a distinct "actuation object" as claimed in the patent, be found in the conventional user interface workflow of the accused Wear OS? The answer will likely depend on the court's construction of "actuation object".
2. A question of functional correspondence: Does the accused Wear OS perform a function that meets the patent’s definition of "selectably aggregate" applications? The case may turn on whether creating a unified list of application icons, as depicted in the patent, is required, or if a standard notification feed is sufficient to meet this limitation.
3. A question of patent eligibility: Although the plaintiff has preemptively argued for the patent's validity under 35 U.S.C. § 101, a key issue will be whether the claims are directed to the abstract idea of "customizing a user interface" without adding a sufficient inventive concept beyond conventional computer functions. The court will have to analyze if the specific sequence of aggregating applications and altering parameters provides the required technological improvement.
