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 section identifies the problem that mobile phones are "very smooth and delicate," making them susceptible to "abrasion" and "ill-favored scars" that deteriorate their quality and value. It also notes that users spend significant money replacing phones to keep up with fashion trends. (’195 Patent, col. 1:31-44).
- The Patented Solution: The invention proposes a protective mask, comprising an upper and lower cover body, that can be joined to the front and rear housings of a mobile phone. (’195 Patent, Abstract). This "sheathe" protects the phone and allows for aesthetic customization through printed patterns or nameplates, as shown in the embodiment of Figure 3, which illustrates separate front and back pieces. (’195 Patent, col. 2:31-35; Fig. 3).
- Technical Importance: This approach offered a method to both protect a mobile device from damage and alter its appearance to match trends, thereby reducing the need for consumers to purchase entirely new phones. (’195 Patent, col. 1:53-58).
Key Claims at a Glance
- The complaint asserts independent Claim 9. (Compl. ¶21).
- Essential elements of Claim 9 include:
- 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.
- The first mask portion having flanges to allow the first mask portion to be coupled to the mobile phone for retention.
- The coupling retains the mask portion so that it covers the first portion of the exterior housing. (’195 Patent, col. 4:33-43).
- The complaint does not explicitly reserve the right to assert dependent claims of the ’195 patent.
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 of phone delicateness, abrasion, and the cost of following fashion trends as its parent ’195 Patent. (’676 Patent, col. 1:31-44).
- The Patented Solution: This patent claims a protective mask described as a single, "integrally-formed mask body" designed for "frictional retention." (’676 Patent, col. 3:32-44). It emphasizes a tight fit with "substantially continuous surface-to-surface contact" and "no substantial space" between the mask and the phone, secured by "at least one retainer having an extension protruding laterally inward" from the mask body. (’676 Patent, col. 3:45-65). This describes a design more akin to a modern, single-piece snap-on case.
- Technical Importance: The claimed invention reflects a shift toward single-piece protective cases that rely on precise molding and material properties to achieve a secure, friction-based fit without multi-part assembly. (’676 Patent, col. 4:18-32).
Key Claims at a Glance
- The complaint asserts independent Claims 1, 5, 8, and 9. (Compl. ¶28).
- Essential elements of Claim 1 include:
- 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.
- An inner surface providing "substantially continuous surface-to-surface contact" with the housing.
- At least one opening for user access to interfaces.
- At least one retainer with a "laterally inward" extension that is retained at an "exterior housing edge." (’676 Patent, col. 3:32-68, col. 4:1-2).
- The complaint explicitly states that the Accused Products also likely infringe dependent Claims 2, 3, 4, 6, 7, 10, 11, and 12. (Compl. ¶31, 34, 39).
III. The Accused Instrumentality
Product Identification
- The Accused Products are Defendant's "Everyday Case" line of protective masks for various models of Apple iPhone, Samsung Galaxy, and Google Pixel mobile devices. (Compl. ¶14; Ex. C).
Functionality and Market Context
- The Accused Products are described as protective masks that couple to a mobile device to prevent it from falling out. (Compl. ¶16). The complaint alleges they comprise a "flange or retainer" and achieve retention through "substantial surface to surface contact" by conforming to the phone's contour. (Compl. ¶16). Visuals provided in the complaint depict a single-piece case with a textured fabric exterior and a raised lip around the interior perimeter. One image provides a close-up view of the interior of the case and its surrounding edge. (Compl. p. 6, top right image). The products are marketed and sold nationally through Defendant's website. (Compl. ¶7).

Identified Points of Contention
- Scope Questions: A primary question for the ’195 Patent is whether the term "flanges," which is described in the specification as a "plurality of flanges 21" (’195 Patent, col. 2:37), can be construed to read on the continuous retaining lip of the accused single-piece case. Further, a question arises as to whether the "first mask portion" limitation, taught in the context of a two-part cover, can read on an entire single-body case.
- Technical Questions: For the ’676 Patent, the dispute may center on whether the raised perimeter lip of the accused case is a "retainer having an extension protruding laterally inward" as claimed, or if it is merely an integral sidewall of the molded body. The evidence presented will need to distinguish the structure of the accused case from a generic molded shape to satisfy this specific structural limitation.
V. Key Claim Terms for Construction
The Term: "flanges" (’195 Patent, Claim 9)
Context and Importance: The infringement allegation for the ’195 Patent hinges on whether the retaining lip of the modern, single-piece Accused Products meets the "flanges" limitation. The patent specification's depiction of this element will be central to this dispute.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim requires "flanges" (plural) but does not specify their form, number, or that they must be discrete. A plaintiff could argue that any plurality of retaining points along a continuous lip meets the plain meaning and purpose of the term.
- Evidence for a Narrower Interpretation: The specification explicitly discloses a "plurality of flanges 21" and Figure 3 depicts them as discrete, separate projections. (’195 Patent, col. 2:37; Fig. 3). A defendant may argue this disclosure limits the term to such separate structures, excluding a continuous, unitary lip.
The Term: "at least one retainer having an extension protruding laterally inward" (’676 Patent, Claim 1)
Context and Importance: This term is the core structural element for retention in the ’676 Patent. Practitioners may focus on this term because its construction will determine if a common feature of modern snap-on cases—a continuous raised edge—is sufficient to infringe, or if a more distinct structure is required.
Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim language uses "at least one," and does not require the "retainer" to be a separate component from the "integrally-formed mask body." A party could argue the entire perimeter lip functions as a single "retainer" and its inward-protruding profile is the "extension."
- Evidence for a Narrower Interpretation: The phrasing "retainer having an extension" could imply a more complex structure than a simple uniform lip, suggesting a part (the retainer) that possesses a feature (the extension). The prosecution history and the incorporated disclosure of the parent ’195 Patent, which shows distinct "flanges," may be used to argue for a more limited scope. (’676 Patent, col. 2:41-42).
VI. Other Allegations
- Willful Infringement: The complaint does not contain a formal count for willfulness. However, it alleges that Defendant had notice of both the ’195 Patent and the ’676 Patent and the likelihood of infringement "at least as early as the filing of this Complaint." (Compl. ¶25, 41). These allegations may form the basis for a post-filing willfulness claim or a claim for enhanced damages should infringement be found.
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of definitional scope and technological evolution: can the term "flanges" from the 2011-issued ’195 Patent, which is rooted in a specification describing discrete parts for a two-piece cover, be construed to cover the integrated, continuous lip of a modern, single-body phone case?
- A key question of structural interpretation will arise for the ’676 Patent: does the continuous, molded edge of the accused case constitute the specifically claimed "retainer having an extension protruding laterally inward," or will the court find a mismatch between the claim's specific structural language and the accused product's unitary design?
- Finally, the effect of the terminal disclaimer linking the two patents may become a pivotal legal question, raising the issue of whether the scope of the later ’676 Patent claims must be interpreted as patentably distinct from the claims of the earlier ’195 Patent, potentially constraining how broadly the ’676 claims can be read.
