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 time were "very smooth and delicate," making them susceptible to "abrasion" and "ill-favored scars" from user carelessness, which deteriorates their quality and value ('195 Patent, col. 1:33-39). It also notes the "waste of money" when users replace entire phones simply to adhere to changing fashion trends ('195 Patent, col. 1:40-44).
- The Patented Solution: The invention is a two-part protective mask, comprising an "upper cover body" and a "lower cover body," that sheathes the front and rear housings of a mobile phone ('195 Patent, Abstract; col. 2:30-32). These covers are retained on the phone using "a plurality of flanges" that catch the edge of the phone's housing, providing temporary protection and allowing for easy customization with different patterns or types without replacing the phone itself ('195 Patent, col. 2:35-40, 52-58).
- Technical Importance: The invention provided a method for both protecting a mobile device and altering its appearance in a non-permanent way, addressing both practical and aesthetic consumer demands. ('195 Patent, col. 1:45-58).
Key Claims at a Glance
- The complaint asserts independent Claim 9 (Compl. ¶26).
- Claim 9 requires:
- 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 it to be coupled to the mobile phone.
- The flanges retain the first mask portion to the first portion of the exterior housing, so that the first mask portion covers it.
- The complaint does not explicitly reserve the right to assert dependent claims for the ’195 Patent.
U.S. Patent No. 10,097,676 - Protective Mask of Mobile Phone, Issued October 9, 2018
The Invention Explained
- Problem Addressed: The ’676 Patent, which is part of the same patent family as the ’195 Patent, addresses the same problem of protecting delicate mobile phone housings from scratches and allowing for stylistic customization without replacing the device ('676 Patent, col. 1:33-48).
- The Patented Solution: This patent describes a protective mask as a single, "integrally-formed mask body" that fits onto the phone via "frictional retention" ('676 Patent, col. 3:37-43). The retention mechanism is further defined as "at least one retainer having an extension protruding laterally inward" that engages with an "exterior housing edge" of the phone when the mask is coupled to it ('676 Patent, col. 4:32-40). The design emphasizes a tight, conforming fit with "substantially continuous surface-to-surface contact" and no substantial gaps ('676 Patent, col. 4:22-29).
- Technical Importance: This design represents an evolution toward a more streamlined, single-piece protective case that relies on both friction and a mechanical lip or "retainer" for secure attachment, reflecting a common design paradigm for modern smartphone cases. ('676 Patent, col. 3:37-43).
Key Claims at a Glance
- The complaint asserts independent Claims 1, 5, 8, and 9 (Compl. ¶33).
- Claim 1 requires:
- A protective mask molded for frictional retention to a mobile phone's exterior housing.
- An integrally-formed mask body molded and contoured to conform and frictionally-fit tightly against the housing.
- An inner surface of the mask body in substantially continuous surface-to-surface contact with the housing.
- At least one opening permitting user access to interfaces.
- At least one retainer with an extension protruding laterally inward, which is retained to an exterior housing edge when the mask is coupled to the device.
- The complaint states that one or more Accused Products also likely infringe dependent Claims 3, 4, 6, 7, 11, and 12 (Compl. ¶¶36, 39, 44).
III. The Accused Instrumentality
Product Identification
- The Accused Products are "protective masks" (phone cases) for various Apple iPhone models, including the iPhone 6 through iPhone 14 series (Compl. ¶¶18-19). The complaint identifies specific product lines such as the "Victoria + Coco," "Jolie," and "Storm" cases (Compl. ¶11).
Functionality and Market Context
- The complaint alleges the Accused Products are protective masks that couple to a mobile device to prevent it from falling out (Compl. ¶21). Their functionality is said to rely on a "flange or retainer" and "substantial surface to surface contact" between the case's inner surface and the phone's outer surface (Compl. ¶21). The complaint provides photographs of the accused "Victoria + Coco" case, showing its exterior, interior, and a close-up of the lip that extends over the phone's edge (Compl. p. 8). The products are sold through Defendant's website and other online marketplaces like Macy's, QVC, and Etsy (Compl. ¶12).

- Identified Points of Contention:
- Scope Questions: A central question for the '195 Patent will be whether Claim 9, which recites only "a first mask portion," can read on a single-piece phone case. The specification of the '195 Patent consistently describes the invention as a two-part assembly of an "upper cover body" and a "lower cover body" ('195 Patent, col. 2:30-32), which may suggest that a "first mask portion" implicitly requires a second.
- Technical Questions: The infringement analysis for both patents will focus on whether the lip or rim of the accused single-piece cases meets the definition of "flanges" ('195 Patent) or a "retainer having an extension protruding laterally inward" ('676 Patent). The complaint provides a close-up photograph of this feature (Compl. p. 8), but the court will need to determine if this structure performs the function described in the patents in the same way.
V. Key Claim Terms for Construction
The Term: "flanges" ('195 Patent, Claim 9)
- Context and Importance: This term defines the retaining structure in the asserted claim of the '195 Patent. The infringement case depends on whether the continuous lip on the accused cases can be properly characterized as "flanges."
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The term "flanges" is not explicitly defined in the patent, which may support giving it its plain and ordinary meaning, potentially covering any projecting rim or edge used for attachment.
- Evidence for a Narrower Interpretation: The specification refers to and illustrates "a plurality of flanges 21" ('195 Patent, col. 2:37-38), which appear in Figure 3 as discrete, hook-like structures. A party may argue that the term should be limited to such distinct, plural structures rather than a single, continuous lip.
The Term: "retainer" ('676 Patent, Claim 1)
- Context and Importance: This term is the key structural limitation for attachment in the asserted claims of the '676 Patent. Practitioners may focus on this term because its construction will determine whether a simple friction-fit case with a minimal retaining lip falls within the claim scope.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim itself provides a functional and structural definition: a "retainer" is a structure with "an extension protruding laterally inward" that "is retained to the exterior housing at an exterior housing edge" ('676 Patent, col. 4:32-40). A party could argue that any structure meeting this description, regardless of its specific form, qualifies.
- Evidence for a Narrower Interpretation: While not narrowly defined, the term appears in claims that also require the mask to "frictionally-fit tightly against the exterior shape" ('676 Patent, col. 4:18-21). A party might argue that the "retainer" must be a distinct feature that provides a retaining function beyond mere friction, potentially requiring a more pronounced mechanical engagement than what is present on a standard case.
VI. Other Allegations
- Willful Infringement: The complaint does not include a formal count for willful infringement. However, it alleges facts that could support a future claim for willfulness by asserting that Defendant had notice of both the '195 and '676 Patents and the likelihood of infringement as of December 7, 2023, based on email correspondence with a confirmed read receipt (Compl. ¶¶30, 46).
VII. Analyst’s Conclusion: Key Questions for the Case
A primary issue will be one of definitional scope: can the terms "flanges" from the '195 Patent and "retainer" from the '676 Patent, which are described in patent specifications illustrating older, two-part phone covers, be construed to read on the integrated, continuous retaining lip of a modern, single-piece smartphone case?
A key legal and factual question for the '195 Patent will be one of claim interpretation in context: does Claim 9's recitation of only "a first mask portion" encompass a single-piece case, or does the specification's consistent description of a two-part invention require the claim to be interpreted as applying only to a component of a multi-part system?
An evidentiary question will be one of functional operation: does the accused cases' simple perimeter lip function as the claimed "flanges" or "retainer" to "retain" the case to the phone, or is retention primarily achieved through the "frictional fit" also recited in the '676 patent claims, potentially rendering the lip's contribution insignificant for the purpose of the infringement analysis?
