II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 7,941,195 - Protective Mask of Mobile Phone, Issued May 10, 2011
The Invention Explained
- Problem Addressed: The patent describes that mobile phones of the era were "very smooth and delicate," making them susceptible to abrasion and "ill-favored scars" from normal use, which deteriorates their quality and value. Additionally, users often spend significant money to replace phones to keep up with trends and fashion. (’195 Patent, col. 1:32-45).
- The Patented Solution: The invention proposes a protective mask, comprising an "upper cover body" and a "lower cover body," that sheathes the front and rear of a mobile phone. This two-part assembly is designed to prevent scratches and can be produced with various patterns or designs, allowing users to change the phone's appearance without replacing the device itself. (’195 Patent, col. 2:27-46, Fig. 3).
- Technical Importance: The invention provided a method for both protecting and customizing early-generation mobile phones, addressing dual concerns of durability and aesthetics in the nascent mobile device market. (’195 Patent, col. 1:46-54).
Key Claims at a Glance
- The complaint asserts independent claim 9. (Compl. ¶24).
- Claim 9 requires:
- A protective mask adapted to be coupled to an exterior housing of a mobile phone.
- The mask comprises a first mask portion, molded to conform to the shape of a first portion of the exterior housing.
- The first mask portion has flanges to allow it to be coupled to the mobile phone.
- The coupling retains the first mask portion to cover the first portion of the exterior housing.
U.S. Patent No. 10,097,676 - Protective Mask of Mobile Phone, Issued October 9, 2018
The Invention Explained
- Problem Addressed: Like its parent, the ’676 Patent addresses the problem of mobile phones being easily damaged through abrasion, which creates "ill-favored scars" and reduces the device's value and quality. (’676 Patent, col. 1:35-41).
- The Patented Solution: The solution described in the claims is a single, "integrally-formed mask body" that is "molded and contoured to conform and frictionally-fit tightly" against the phone's exterior housing. The mask is held in place by "at least one retainer" which is an extension that protrudes "laterally inward from the integrally-formed mask body" to engage an edge of the housing. (’676 Patent, col. 3:41-44, col. 3:55-63).
- Technical Importance: This patent describes a one-piece, snap-on style case that secures to a device via frictional fit and retaining structures, representing a common design paradigm for modern smartphone cases. (’676 Patent, col. 2:15-22).
Key Claims at a Glance
- The complaint asserts independent claims 1, 5, 8, and 9. (Compl. ¶31).
- Claim 1 requires an "integrally-formed mask body" with an inner surface in "substantially continuous surface-to-surface contact" with the phone, "at least one opening" for user interfaces, and "at least one retainer" protruding inward to hold the mask on the device.
- Claim 5 is similar to claim 1 but describes the mask as having an "opening enabling the mask to be placed over the exterior shape" of the device.
- Claim 8 requires a mask for a hand-held mobile phone where the "integrally-formed mask body is coextensive with, contours to and overlies the opposed side surfaces" of the phone with "substantially no space" between the mask and the sides.
- Claim 9 is similar to claim 1 but describes the inner surface as "closely conforming" and providing retention, with the mask being "molded, integrally formed, contoured and sized to fit tightly."
- The complaint also reserves the right to assert dependent claims 2-4, 6-7, and 10-12. (Compl. ¶34, ¶37, ¶42).
III. The Accused Instrumentality
Product Identification
- The complaint identifies the "Accused Products" as a wide array of protective cases for Apple and Samsung phones and tablets sold by Defendant. (Compl. ¶17). Two exemplary products are named and pictured: the "GOOD VIBES ONLY" case for iPhone XS and the "PRESTIGE FOLIO" case for iPad mini 6. (Compl. ¶9).
Functionality and Market Context
- The Accused Products are described as protective masks that couple to a mobile device to secure it. (Compl. ¶19). They are alleged to use a "flange or retainer" and "substantial surface to surface contact" to conform to the device's contour and provide protection. (Compl. ¶19). An interior view of the "PRESTIGE FOLIO" case shows the single-piece molded body with openings for device features. (Compl. p. 9). A side view of the "GOOD VIBES ONLY" case illustrates the profile of the protective edge designed to retain the phone. (Compl. p. 8). The complaint alleges these products are sold through Defendant's website and on Amazon. (Compl. ¶10).

Identified Points of Contention
- Scope Questions: A central question for the ’195 Patent may be whether a single, unitary case can satisfy the "first mask portion" limitation. The specification and drawings consistently depict a two-part assembly, which may suggest that a "first mask portion" is necessarily one component of a multi-part system. The complaint's allegations for Claim 9 strategically omit any reference to a second portion.
- Technical Questions: For the ’676 Patent, the analysis may focus on whether the accused cases meet the physical requirements of the claims. Key questions could include: (1) What quantum of contact satisfies the "substantially continuous surface-to-surface contact" limitation? (2) Does the continuous lip around the perimeter of the accused cases constitute "at least one retainer having an extension protruding laterally inward," or does the claim require a more discrete structure?
V. Key Claim Terms for Construction
The Term: "a first mask portion" (’195 Patent, Claim 9)
- Context and Importance: The ’195 Patent specification heavily emphasizes a two-part construction ("upper cover body" and "lower cover body"). The accused products appear to be single-piece cases. The viability of the infringement claim against a single-piece product may depend on whether "a first mask portion" can be construed to mean the entirety of a unitary case, rather than one component of a two-part system.
- Intrinsic Evidence for a Broader Interpretation: Claim 9 recites "a" first mask portion, and does not explicitly require a second mask portion, unlike other claims in the patent family.
- Intrinsic Evidence for a Narrower Interpretation: The detailed description repeatedly refers to the invention as comprising "an upper cover body 20 and a lower cover body 30." (’195 Patent, col. 2:27-28). All figures, such as Figure 3, illustrate two distinct components being assembled onto the phone, which could be used to argue the term implicitly requires a multi-part context.
The Term: "at least one retainer" (’676 Patent, Claims 1, 5, 8, 9)
- Context and Importance: This term defines the primary mechanism for securing the mask to the phone. The infringement analysis will turn on what physical structure meets this definition. Practitioners may focus on this term because the accused products appear to use a continuous peripheral lip, and the dispute will be whether that lip is a "retainer."
- Intrinsic Evidence for a Broader Interpretation: The claim defines the term functionally as "participating in retaining the integrally-formed mask body" and structurally as "an extension protruding laterally inward." (’676 Patent, col. 3:55-63). This broad language could support an interpretation that includes any inwardly-projecting edge that helps hold the case on.
- Intrinsic Evidence for a Narrower Interpretation: The specification of the parent '195 patent, from which the '676 patent claims priority, describes and illustrates "a plurality of flanges 21" as the retaining structures. (’195 Patent, col. 2:38-39). A defendant may argue that "retainer" in the continuation '676 patent should be interpreted in light of these more specific "flange" structures, rather than a continuous lip.
VI. Other Allegations
- Indirect Infringement: The complaint does not contain allegations of indirect infringement (induced or contributory). It alleges only direct infringement by the Defendant. (Compl. ¶24, ¶31).
- Willful Infringement: The complaint does not use the term "willful." It alleges Defendant had notice of the patents and the likelihood of infringement "at least as early as the filing of this Complaint." (Compl. ¶28, ¶44). This allegation establishes a basis for seeking enhanced damages for any post-filing infringement but does not assert pre-suit willfulness.
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of definitional scope: can the term "a first mask portion" from the ’195 Patent, which is described in the specification as part of a two-piece assembly, be construed to read on the accused single-piece protective cases?
- A key evidentiary question will be one of structural interpretation: does the continuous peripheral lip of the accused products meet the specific structural requirements of the "at least one retainer" limitation in the ’676 Patent, or does the patent family's disclosure limit that term to more discrete structures like flanges?
- A third question relates to the procedural posture and damages: the complaint alleges an infringement period that ends in November 2022, two years before the complaint was filed. The basis for this specific end date, and whether it represents an assertion that infringement has ceased or that the patents have expired, will likely be a significant factor in the litigation, particularly concerning the scope of damages and the availability of injunctive relief.
