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’s background section states that mobile phone housings are often "smooth and delicate," making them susceptible to "abrasion... due to carelessness of a user." This can lead to "ill-favored scars," which deteriorates the phone's quality and resale value. Additionally, it notes the "waste of money" when users replace entire phones simply to follow design trends. (’195 Patent, col. 1:31-44).
- The Patented Solution: The invention proposes a removable protective mask, comprising separate upper and lower cover bodies, that can be joined with the front and rear housings of a mobile phone. This mask "sheathe[s] the mobile phone" to prevent scratches. The specification describes embodiments where the mask includes "flanges" that retain it on the phone's housing. (’195 Patent, col. 2:32-43). The design, primarily illustrated with flip phones, allows for protection and customization without replacing the device itself.
- Technical Importance: This technology offered a method for users to both protect their devices from cosmetic damage and alter their appearance, responding to a growing consumer market for mobile accessories. (’195 Patent, col. 1:45-55).
Key Claims at a Glance
- The complaint asserts independent Claim 9. (Compl. ¶22).
- Claim 9 recites a protective mask comprising:
- a first mask portion, molded to conform to the shape of a first portion of the exterior housing of the mobile phone; and
- the first mask portion having flanges to allow the first mask portion to be coupled to the mobile phone to retain the first mask portion to 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: Similar to its parent, the ’676 Patent addresses the problem of mobile phones being easily damaged through abrasion from normal use, which creates "ill-favored scars" and diminishes the device's value and quality. (’676 Patent, col. 1:33-39).
- The Patented Solution: The ’676 Patent claims an "integrally-formed mask body" (a single piece) that is "molded and contoured to conform and frictionally-fit tightly against the exterior shape of the exterior housing." (’676 Patent, col. 3:41-44). Retention is achieved by "at least one retainer having an extension protruding laterally inward from the integrally-formed mask body" which is "retained to the exterior housing at an exterior housing edge." (’676 Patent, col. 3:55-62). This describes a more modern, single-piece snap-on or slip-on phone case.
- Technical Importance: The invention reflects an evolution toward single-piece protective cases that offer a secure fit through friction and precisely molded retaining features, a dominant design in the modern smartphone market. (’676 Patent, col. 3:31-40).
Key Claims at a Glance
- The complaint asserts independent Claims 1, 5, 8, and 9. (Compl. ¶29).
- Claim 1, the first asserted independent claim, recites a protective mask comprising:
- an integrally-formed mask body molded and contoured to conform and frictionally-fit tightly against the exterior shape of the exterior housing;
- an inner surface of the mask body in substantially continuous surface-to-surface contact with the exterior shape of the exterior housing;
- at least one opening defined by the mask body permitting user access to user input and output interfaces; and
- at least one retainer having an extension protruding laterally inward from the integrally-formed mask body, which is retained to an exterior housing edge.
- The complaint reserves the right to assert dependent Claims 2, 3, 4, 6, 7, 10, 11, and 12. (Compl. ¶32, ¶35, ¶40).
III. The Accused Instrumentality
Product Identification
- The accused products are Pivet’s protective cases for mobile devices, including the ASPECT, Glacier, Sentri, and ZERO product lines, among others. (Compl. ¶15). The complaint specifically identifies and provides images of an "iPhone 11 Pro - glacier+ pro SANKOFA moonstone" case and a "ZERO Black for Samsung Galaxy S22" case as representative examples. (Compl. ¶6, p. 7-8).
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. ¶18). They allegedly achieve this retention through a "flange or retainer" and "substantial surface to surface contact by the inner surface of the protective mask which conforms to the contour of the outer surface of the mobile device." (Compl. ¶18). An image in the complaint shows a representative accused product, the "SANKOFA moonstone" case, both on its own and installed on a phone. (Compl. p. 6). The products are sold through Defendant's own website and major third-party online and retail marketplaces. (Compl. ¶7, ¶17).

- Identified Points of Contention:
- Scope Questions: The ’195 Patent’s specification and figures primarily describe a two-part protective mask for older, flip-style phones. A central question for the court will be whether the term "a first mask portion" in Claim 9 can be construed to read on the entirety of a modern, single-piece smartphone case, or if the claim scope is implicitly limited by the patent's disclosure of a multi-part system.
- Technical Questions: A key technical dispute will concern whether the continuous, molded lip around the perimeter of the accused cases constitutes "flanges" as recited in the ’195 Patent or a "retainer having an extension protruding laterally inward" as recited in the ’676 Patent. The complaint's annotated photographs suggest this structural feature is central to its infringement theory. (Compl. p. 7-8).
V. Key Claim Terms for Construction
For the ’195 Patent:
- The Term: "flanges"
- Context and Importance: This term is the sole structural element for attachment recited in asserted Claim 9. The determination of whether the accused products' continuous retaining lip meets this definition will be critical to the infringement analysis for the ’195 Patent. Practitioners may focus on this term because the patent's figures depict discrete, tab-like structures, whereas the accused products appear to have a continuous rim.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim itself does not define the shape, number, or continuity of the "flanges," which could support an argument that any structure projecting from the mask to couple to the phone is sufficient.
- Evidence for a Narrower Interpretation: The specification repeatedly refers to "a plurality of flanges 21" and shows them in Figure 3 as distinct, separate tabs extending from the rear face of the cover body. (’195 Patent, col. 2:37-39; Fig. 3). This could support a narrower construction limited to discrete, tab-like structures.
For the ’676 Patent:
- The Term: "retainer"
- Context and Importance: This term defines the key mechanism for securing the single-piece mask to the phone in all asserted claims of the ’676 Patent. The infringement case hinges on construing this term to cover the molded inner lip of the accused products.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim uses the general term "retainer" and describes its function as being "retained to the exterior housing at an exterior housing edge." (’676 Patent, col. 3:59-60). This functional language may support a broad definition that includes any structure performing that retaining action.
- Evidence for a Narrower Interpretation: While the claims of the ’676 Patent use the word "retainer," the shared specification describes the retaining structures as "flanges 21." (’676 Patent, col. 2:38-40). A party could argue that the meaning of "retainer" should be informed by or limited to the "flanges" disclosed in the written description and figures.
VI. Other Allegations
- Willful Infringement: The complaint does not use the term "willful," but it pleads facts to support a claim for enhanced damages by alleging Defendant had pre-suit knowledge of both asserted patents and its alleged infringement. The complaint states that notice was first provided on September 20, 2024, and that Defendant's CEO acknowledged receipt and referral to a legal team, but no further substantive communications were received by Plaintiff despite follow-up attempts. (Compl. ¶26, ¶42).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of historical scope: Can Claim 9 of the ’195 patent, which arises from a specification focused on two-part covers for flip phones, be interpreted to cover modern, single-piece cases for slab-style smartphones? This will likely depend on whether "a first mask portion" can be construed independently of the two-part system disclosed in the patent.
- The central dispute may be one of claim construction: Can the terms "flanges" (’195 Patent) and "retainer" (’676 Patent) be construed to read on the continuous, molded inner lip of the accused Pivet cases? The outcome will likely depend on whether these terms are defined by their broad function of retention or are limited to the more specific, discrete structures shown in the patents' figures.
- A key evidentiary question will be one of structural correspondence: Assuming a construction of the key terms, does the physical evidence, including the highlighted portions in the complaint's photographs (Compl. p. 7-8), show that the accused products actually possess the specific structure and perform the retaining function as required by the claims?
