II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 7,941,195 - "Protective Mask of Mobile Phone"
- Patent Identification: U.S. Patent No. 7,941,195, "Protective Mask of Mobile Phone," issued May 10, 2011 (Compl. ¶3).
The Invention Explained
- Problem Addressed: The patent's background describes that mobile phone housings are "very smooth and delicate," which can lead to "abrasion" and "ill-favored scars" due to user carelessness. It also notes the "trend and fashion" aspect of mobile phones, which leads users to spend "a lot of money to change the mobile phone" to stay current (’195 Patent, col. 1:33-44).
- The Patented Solution: The invention is a protective mask, typically comprising an upper and lower cover body, that sheathes the mobile phone to prevent damage. The mask is retained on the phone by "a plurality of flanges" that can be "retained at the edge of the front phone housing." This allows for both protection and customization (e.g., via "Patterns, types, or nameplates") without replacing the phone itself (’195 Patent, col. 2:32-41; Abstract).
- Technical Importance: The invention provided a method for consumers to protect their devices from cosmetic damage and alter their appearance, addressing practical and aesthetic concerns in the growing mobile device market (’195 Patent, col. 1:45-54).
Key Claims at a Glance
- The complaint asserts independent Claim 9 (Compl. ¶25).
- The essential elements of Claim 9 are:
- A protective mask adapted to be coupled to an exterior housing of a mobile phone.
- A first mask portion, molded to conform to the shape of a first portion of the exterior housing of the mobile phone.
- The first mask portion having flanges to allow the first mask portion to be coupled to the mobile phone to retain it, such that the mask portion covers the first portion of the exterior housing.
U.S. Patent No. 10,097,676 - "Protective Mask of Mobile Phone"
- Patent Identification: U.S. Patent No. 10,097,676, "Protective Mask of Mobile Phone," issued October 9, 2018 (Compl. ¶4).
The Invention Explained
- Problem Addressed: The '676 Patent addresses the same problems as its parent '195 Patent: the susceptibility of delicate phone housings to abrasion and the desire for customization without the cost of replacing the entire device (’676 Patent, col. 1:20-44).
- The Patented Solution: This patent describes a protective mask that is "integrally-formed" and molded for "frictional retention" against the phone's housing. The solution emphasizes a tight fit, with an inner surface in "substantially continuous surface-to-surface contact" with the phone. Retention is achieved by "at least one retainer having an extension protruding laterally inward" to engage an edge of the housing, while openings permit access to the phone's interfaces (’676 Patent, Claim 1; col. 4:9-31).
- Technical Importance: This design advanced the protective cover concept by specifying an integrated, single-body construction with a friction-fit and defined retainers, aiming for a more secure and seamless form of device protection (’676 Patent, col. 1:45-65).
Key Claims at a Glance
- The complaint asserts independent Claims 1, 5, 8, and 9 (Compl. ¶32).
- The essential elements of independent Claim 1 are:
- A protective mask molded for frictional retention to a mobile phone's exterior housing.
- An integrally-formed mask body molded to "frictionally-fit tightly" against the housing's exterior shape.
- An inner surface of the mask body in "substantially continuous surface-to-surface contact" with the housing's exterior shape, with "no substantial space" between them.
- At least one opening in the mask body for user access to interfaces.
- At least one retainer with an "extension protruding laterally inward" that is "retained to the exterior housing at an exterior housing edge."
- The complaint explicitly reserves the right to assert dependent Claims 2, 3, 4, 6, 7, 10, 11, and 12 (Compl. ¶35, ¶38, ¶43).
III. The Accused Instrumentality
Product Identification
- The accused instrumentalities are various styles of "protective masks for mobile devices" sold by Defendant under the Trianium brand, including cases for numerous Apple iPhone, Samsung Galaxy, and Google Pixel models, as well as the Apple iPad Pro (Compl. ¶17-19). Representative products identified are the "Trianium Clarium Case Designed For Apple iPhone 11" and the "Trianium Case Compatible For 11-inch iPad Pro Case (2018)" (Compl. ¶9).
Functionality and Market Context
- The accused products are described as protective masks that couple to a mobile device to prevent it from falling out, using a "flange or retainer" and an inner surface that conforms to the device's contour (Compl. ¶21). The complaint includes a marketing image highlighting the accused products' "SNUG & PERFECT FIT" (Compl. p. 6). The products are alleged to feature "raised edges" to protect the screen and camera and "precise cutouts" for ports and buttons (Compl. p. 6-7). A diagram of an accused iPad case with callouts pointing to 'PRECISE CUTOUTS' for the camera, ports, and speakers is provided as evidence (Compl. p. 9). Defendant is alleged to be "one of the biggest leaders in mobile accessories," selling through its website and Amazon storefronts (Compl. p. 3).

Identified Points of Contention
- Scope Questions: The patents-in-suit use the term "mobile phone," and the drawings exclusively depict early 2000s-era phones (’195 Patent, Figs. 1-7). This raises the question of whether the patent claims can be interpreted to cover modern devices with significantly different form factors, such as the accused tablet cases for the "iPad Pro" (Compl. ¶18).
- Technical Questions: A key technical question for the '195 patent will be whether the single continuous "raised edge" on the accused products meets the "flanges" (plural) limitation of Claim 9. For the '676 patent, the analysis may focus on whether the accused products achieve the claimed "frictional retention" and whether their peripheral lip constitutes the claimed "retainer having an extension protruding laterally inward."
V. Key Claim Terms for Construction
The Term: "flanges" (’195 Patent, Claim 9)
- Context and Importance: Claim 9 requires plural "flanges" for retention. The accused products appear to have a single, continuous lip or "raised edge" (Compl. p. 7). The case may turn on whether this single structure can satisfy the plural limitation.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification's primary goal is retention at the phone's edge (’195 Patent, col. 2:38-41). A party could argue that a continuous lip functionally serves as a plurality of flanges acting in concert along the perimeter.
- Evidence for a Narrower Interpretation: The patent's figures appear to show distinct, physically separate protrusions labeled as flanges (21), which may support an argument that "flanges" requires more than one discrete structure and does not read on a continuous rim (’195 Patent, Fig. 3).
The Term: "retainer" (’676 Patent, Claims 1, 5, 8, 9)
- Context and Importance: The asserted claims of the '676 patent require "at least one retainer" that protrudes inward to hold the device. Practitioners may focus on this term because the infringement allegation appears to map it to the simple "raised edge" of the accused cases (Compl. p. 7).
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim language defines the retainer by its function: an "extension protruding laterally inward" that "participat[es] in retaining" the mask body to the device (’676 Patent, col. 4:25-31). This functional language could support construing any inwardly-projecting lip that holds the phone as a "retainer."
- Evidence for a Narrower Interpretation: The specification is rooted in the "flanges" concept from the parent patent, which are depicted as somewhat distinct structures (’676 Patent, col. 2:42-43; Fig. 3). This could be used to argue that "retainer" requires a more structurally defined feature than a simple molded perimeter.
VI. Other Allegations
- Indirect Infringement: The complaint does not include counts for indirect or contributory infringement. The allegations focus on direct infringement by Defendant through its manufacture, sale, and distribution of the Accused Products (Compl. ¶17).
- Willful Infringement: The complaint does not contain an explicit allegation of willful infringement. However, it lays a factual predicate for enhanced damages by alleging that Defendant had pre-suit knowledge of both patents and their likely infringement as of September 1, 2022, based on email correspondence that Defendant allegedly acknowledged receiving (Compl. ¶29, ¶45).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of definitional scope: can the term "mobile phone," rooted in the context of early 2000s-era devices depicted in the patent figures, be construed to cover modern smartphones and, more significantly, large-format tablets like the accused iPad Pro cases? The outcome will test the adaptability of patent claims to evolving technology.
- The case will also likely involve a question of structural interpretation: does the single, continuous "raised edge" found on the accused products satisfy the "flanges" (plural) limitation of the '195 patent and the "retainer" limitation of the '676 patent? This will require the court to decide whether these terms require discrete, separately identifiable structures or can read on a functionally equivalent integrated feature.
- A key practical question will be one of damages: given that both asserted patents expired before the complaint was filed, any potential monetary recovery is strictly limited to past infringement. The central challenge will be establishing a reasonable royalty for the finite infringement periods, which ended in October 2021 for the '676 patent and November 2022 for the '195 patent.
