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 early mobile phones as having "very smooth and delicate" housings susceptible to "abrasion" and "ill-favored scars" from user carelessness, which deteriorates the phone's quality and value. It also notes the user's desire to follow "trend and fashion" often leads to costly phone replacements. (’195 Patent, col. 2:31-42).
- The Patented Solution: The invention proposes a two-part "protective mask," comprising an "upper cover body" and a "lower cover body," which are "integrally formed by mold ejection of plastic" and sheathe the front and rear of a mobile phone. (’195 Patent, col. 2:32-35, col. 2:59-62). This mask protects the phone and allows for customization with different patterns or designs, as depicted in Figure 3, without replacing the phone itself. (’195 Patent, col. 2:52-56).
- Technical Importance: This approach provided a method for users to simultaneously protect and personalize their mobile devices at a time when device form factors were less standardized. (’195 Patent, col. 3:9-16).
Key Claims at a Glance
- The complaint asserts independent Claim 9. (Compl. ¶23).
- Essential elements of Claim 9 include:
- A protective mask adapted to be coupled to an exterior housing of a mobile phone.
- The mask comprises a "first mask portion" that is molded to conform to a portion of the phone's exterior housing.
- This first mask portion has "flanges" that allow it to be coupled to the phone and retain it.
- The first mask portion thereby covers a portion of the phone's exterior housing.
U.S. Patent No. 10,097,676 - “Protective Mask of Mobile Phone,” issued October 9, 2018
The Invention Explained
- Problem Addressed: The ’676 Patent addresses the same problems as its parent ’195 Patent: preventing abrasion on delicate phone housings and allowing for stylistic updates without replacing the device. (’676 Patent, col. 2:32-44).
- The Patented Solution: The invention claims an "integrally-formed mask body" (a single piece) that is "molded for frictional retention" to the phone. (’676 Patent, col. 3:35-36). Key features include an inner surface in "substantially continuous surface-to-surface contact" with the phone's housing and "at least one retainer having an extension protruding laterally inward" to help secure the device. (’676 Patent, col. 3:45-51, col. 3:56-58).
- Technical Importance: This patent describes a form factor more akin to modern "snap-on" or flexible phone cases, which use a single, contoured body and friction fit for protection and retention, a widely adopted design for smartphones. (’676 Patent, col. 3:41-44).
Key Claims at a Glance
- The complaint asserts independent Claims 1, 5, 8, and 9. (Compl. ¶30).
- Essential elements of lead independent 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 in "substantially continuous surface-to-surface contact" with the housing's exterior shape, with "no substantial space" between them.
- At least one opening for user access to interfaces.
- "at least one retainer" with an extension that protrudes "laterally inward" and is retained at an "exterior housing edge" to help hold the mask on the device.
- The complaint reserves the right to assert dependent Claims 2, 3, 4, 6, 7, 10, 11, and 12. (Compl. ¶¶ 33, 36, 41).
III. The Accused Instrumentality
Product Identification
- The accused products are "ULAK" branded protective masks for a wide range of mobile devices, including Apple iPhones, Samsung Galaxy phones, and Apple iPads. (Compl. ¶¶ 16, 17). The complaint identifies multiple "Case Styles," such as "Soft TPU and Hard PC Back Case," "Wallet Case," and "Slim Lightweight Trifold Smart Case." (Compl. ¶16).
Functionality and Market Context
- The complaint alleges the accused products are protective masks that couple to a device to prevent it from falling out, comprising a "flange or retainer." (Compl. ¶19). They are described as having openings for device inputs and outputs. (Compl. ¶19). Visuals in the complaint depict modern, single-piece flexible cases and folio-style wallet cases. (Compl. pp. 6-8). One representative visual shows a single-piece, semi-transparent case for an iPhone 14 with a raised border. (Compl. p. 6). Another shows a "Wallet Case" with a folio cover and an interior TPU shell for holding the phone. (Compl. p. 7). A third shows a trifold "Smart Shell" case for an iPad. (Compl. p. 8). The products are marketed and sold nationally through Defendants' own website as well as major online retailers like Amazon and Walmart. (Compl. ¶8).
IV. Analysis of Infringement Allegations
’195 Patent Infringement Allegations
| Claim Element (from Independent Claim 9) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| A protective mask adapted to be coupled to an exterior housing of a mobile phone... | The Accused Products are protective masks designed to be coupled to mobile phones. | ¶24 | col. 4:32-36 |
| a first mask portion, molded to conform to the shape of a first portion of the exterior housing of the mobile phone; | The Accused Products comprise a first mask portion molded to conform to the shape of the mobile phone's exterior. | ¶25a | col. 4:36-38 |
| 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... | The Accused Products' first mask portion has flanges that couple it to the mobile phone to retain it. | ¶25b | col. 4:38-42 |
| ...so that the first mask portion covers the first portion of the exterior housing of the mobile phone. | The first mask portion of the Accused Products covers the exterior housing of the mobile phone. | ¶25b | col. 4:42-44 |
- Identified Points of Contention:
- Scope Questions: The primary infringement question for the ’195 Patent is one of claim scope. The patent’s specification and figures describe a two-part protective mask with a distinct "upper cover body" and "lower cover body" (’195 Patent, col. 2:30-31; Fig. 3). A court may need to decide whether the asserted "first mask portion" of Claim 9 can read on the accused modern, single-piece case designs, or if the claim is limited to a component of a multi-part shell.
- Technical Questions: The complaint alleges the accused products have "flanges" but does not identify the specific structure. (Compl. ¶25b). This raises the question of whether the continuous, raised lip or bezel of a modern TPU case can be considered a "flange" as that term is used in the patent, which depicts flanges as discrete tabs (element 21 in Fig. 3).
’676 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| A protective mask molded for frictional retention to an exterior housing of a mobile phone... | The Accused Products are protective masks molded for frictional retention to a mobile phone. | ¶31 | col. 3:35-40 |
| an integrally-formed mask body molded and contoured to conform and frictionally-fit tightly against the exterior shape of the exterior housing; | The Accused Products are an integrally-formed mask body molded to conform and frictionally fit tightly against the phone's exterior. | ¶32a | col. 3:41-44 |
| an inner surface of the integrally-formed mask body... conforming to and in substantially continuous surface-to-surface contact with the exterior shape of the exterior housing, with no substantial space between... | The inner surface of the Accused Products conforms to the phone's exterior with no substantial space between them. | ¶32b | col. 3:45-51 |
| at least one opening defined by the integrally-formed mask body permitting user access to at least the user input and output interfaces; | The Accused Products have at least one opening that permits user access to the phone's interfaces. | ¶32c | col. 3:52-55 |
| at least one retainer having an extension protruding laterally inward from the integrally-formed mask body... wherein the at least one retainer is retained to the exterior housing at an exterior housing edge... | The Accused Products have at least one retainer with an extension protruding inward that is retained at the phone's edge. | ¶32d | col. 3:56-63 |
- Identified Points of Contention:
- Technical Questions: A key factual dispute may concern the "retainer" element. The complaint alleges this feature exists but does not specify which part of the accused case constitutes the "retainer having an extension protruding laterally inward." (Compl. ¶32d). It will be a question of fact whether the entire raised lip of the case satisfies this limitation, or if the claim requires a more specific, localized structure.
- Scope Questions: The proper construction of "substantially continuous surface-to-surface contact" may be at issue, particularly with respect to flexible cases that might primarily contact a device at its corners and edges to achieve a friction fit.
V. Key Claim Terms for Construction
The Term: "flanges" (’195 Patent, Claim 9)
- Context and Importance: This term's construction is critical for the ’195 Patent. The accused products are modern, single-piece cases with a continuous lip around the screen. Whether that lip constitutes "flanges" will likely determine infringement. Practitioners may focus on this term because it appears to be the primary structural mismatch between the patent's disclosure and the accused technology.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim requires "flanges" that "allow the first mask portion to be coupled to the mobile phone to retain" it. (’195 Patent, col. 4:38-41). One could argue this is a functional definition, and any structure on the mask's edge performing this retention function, including a continuous lip, qualifies.
- Evidence for a Narrower Interpretation: The patent’s figures consistently depict "flanges 21" as multiple, discrete, tab-like protrusions on the edge of the upper cover body, not as a continuous, uniform structure. (’195 Patent, Fig. 3, Fig. 5). This could support a narrower definition requiring distinct, tab-like structures.
The Term: "retainer" (’676 Patent, Claims 1, 5, 8, and 9)
- Context and Importance: This term is the key retaining mechanism described in the asserted claims of the ’676 Patent. Proving that the accused products possess this specific structure, as distinct from a simple form-fitting body, will be central to the plaintiff's case.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim broadly defines the retainer as "an extension protruding laterally inward from the integrally-formed mask body." (’676 Patent, col. 3:56-58). This language could plausibly cover the entire peripheral lip of a modern phone case that extends over the bezel of the device's screen.
- Evidence for a Narrower Interpretation: The claim requires the retainer to be "retained to the exterior housing at an exterior housing edge." (’676 Patent, col. 3:60-61). This may suggest a more specific point or line of contact rather than the general pressure fit of the entire case. Further, the ’676 Patent incorporates by reference and uses the same drawings as the ’195 Patent, which show distinct retaining structures (flanges 21). A defendant may argue this context limits the term "retainer" to something more specific than a simple continuous lip.
VI. Other Allegations
- Indirect Infringement: The complaint does not plead separate counts for indirect infringement. The counts are titled "INFRINGEMENT OF UNITED STATES PATENT..." and allege direct infringement by Defendants through acts of making, using, selling, and offering for sale. (Compl. ¶¶ 23, 24, 30, 31).
- Willful Infringement: While the complaint does not explicitly use the word "willful," it lays a factual predicate for such a claim by alleging that Defendants had pre-suit knowledge of both patents. The complaint states that notice letters were sent on November 18, 2022, and December 21, 2022. (Compl. ¶¶ 27, 43). The timing is notable, as the ’676 Patent expired in 2021 (before the notice), and the ’195 Patent expired on or about November 16, 2022, two days before the first alleged notice letter.
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of claim scope versus technological evolution: can the term "flanges" from the ’195 patent, which is disclosed in the context of a two-part shell with discrete tabs, be construed to cover the continuous, integrally-molded lip of the accused modern, single-piece phone cases?
- A key evidentiary question for the ’676 patent will be one of structural identification: what specific feature of the accused cases constitutes the claimed "retainer having an extension protruding laterally inward," and can the plaintiff provide sufficient evidence to distinguish this element from the general form-fitting nature of the case?
- As both patents expired before the suit was filed, the case will center on the calculation of past damages. A critical question will be whether any conduct by the Defendants after receiving notice could give rise to enhanced damages, particularly for the ’195 patent, where the alleged notice (Nov. 18, 2022) arrived almost immediately after its expiration (Nov. 16, 2022).
