II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 9,480,319 - "Protective Case for Portable Electronic Device"
- Patent Identification: U.S. Patent No. 9,480,319, "Protective Case for Portable Electronic Device," issued November 1, 2016.
The Invention Explained
- Problem Addressed: The patent describes a need to protect fragile smartphones without using cases that are "bulky, unsightly, and can limit access to the device screen or control buttons" (’319 Patent, col. 1:20-22).
- The Patented Solution: The invention is a protective case, typically with two layers, featuring a specific edge geometry. The outer edges of the case that run along the shorter top and bottom sides of the phone are raised to a height "H," while the edges along the longer sides of the phone have a lower height "h" (’319 Patent, col. 5:45-52). This design purports to lift the screen off a flat surface to prevent scratches, while the lower side edges ensure that a user can still easily access the sides of the touchscreen for actions like "finger-swiping" (’319 Patent, col. 5:55-58).
- Technical Importance: The design attempts to resolve the inherent conflict between providing a protective lip around a smartphone screen and enabling full access to the screen’s entire surface area.
Key Claims at a Glance
- The complaint asserts dependent claims 12, 15, 18, and 19, and independent claim 14 (Compl. ¶12). Claims 12 and 14 are based on two different independent claims.
- Independent Claim 8 (basis for asserted claim 12): The essential elements include:
- A first panel with a central opening.
- Four edge panels with different heights.
- A first pair of edge panels having a "first height."
- A second pair of edge panels having a "second height less than the first height."
- Independent Claim 14: The essential elements include:
- A first panel with a central opening and at least four edge panels.
- Four corners at the intersections of the panels.
- At least two edge panels having a "first height."
- The four corners having a "second height substantially equivalent to the first height."
- The other two edge panels having a "third height less than the first height and the second height."
- The complaint asserts infringement of these claims and several dependent claims that add further limitations, such as defining a "taper" or adding a "resilient layer" (Compl. ¶¶15, 17).
U.S. Patent No. 10,327,524 - "Protective Case for Portable Electronic Device"
- Patent Identification: U.S. Patent No. 10,327,524, "Protective Case for Portable Electronic Device," issued June 25, 2019.
The Invention Explained
- Problem Addressed: The '524 Patent, which is a continuation of the '319 Patent application, addresses the same problem of balancing smartphone protection with screen accessibility (’524 Patent, col. 1:15-18).
- The Patented Solution: This patent claims the same general concept but with more specific geometric language. The claims are structured around a case having "two short edge panels" and "two long edge panels" with different, specified heights (’524 Patent, col. 7:21-30). The claims also focus on the "edge corner" geometry, defining "transitions" between the high and low panels and requiring the panels themselves to have "only one height that continuously spans" the distance between these transitions (’524 Patent, col. 7:31-48).
- Technical Importance: By using more detailed geometric language, the claims may have been drafted to more precisely capture specific case designs or to distinguish the invention from prior art.
Key Claims at a Glance
- The complaint asserts independent claims 1 and 28, along with numerous dependent claims (Compl. ¶19).
- Independent Claim 1: The essential elements include:
- A first panel with two short and two long edge panels extending from it.
- The short edge panels have a "first height" and the long edge panels have a "second height," where the second is less than the first.
- "Edge corners" at the intersections have a "third height" and include "transitions" to the second height of the long panels.
- The short and long edge panels each have "only one height that continuously spans" the distance between the corners or transitions.
- Independent Claim 28: The essential elements include:
- A first panel with "upper and lower edges" and "first and second side edges."
- The upper and lower edges have a "first, continuous height."
- The first and second side edges have a "second, continuous height" that is less than the first height.
- "Transitions" defined by a "taper or a step" connect the corners to the side edges.
- The complaint reserves the right to assert numerous other dependent claims adding features like symmetry, openings for ports, and tabs for buttons (Compl. ¶¶23-26, 30-31, 35-38).
III. The Accused Instrumentality
Product Identification
The accused products are a wide range of protective smartphone cases sold by Defendant under series names such as "Damda High Pro Shield," "Damda Crystal Mixx," "Damda Glide Shield," and "Crystal Bumper" for various Samsung Galaxy models (Compl. ¶12, pp. 4-6).
Functionality and Market Context
The complaint alleges these products are protective cases for electronic devices (Compl. ¶13). The infringement theory is based on their physical structure, specifically that they possess a design with side walls that are shorter than the top and bottom walls (Compl. ¶13). The complaint alleges this feature is for exposing a portion of the device's screen while still offering protection (Compl. ¶13). The complaint indicates that an exhibit contains figures illustrating the accused products' varying edge heights (Compl. ¶13, citing Ex. C, Figs. 1-5).

Identified Points of Contention
- Scope Questions: A central dispute may arise over the meaning of geometric and relational terms. For the '319 Patent, the term "substantially equivalent" will be critical in determining how much, if any, variation is permitted between the corner height and the top/bottom edge height. For the '524 Patent, the scope of "only one height that continuously spans" raises the question of whether any ergonomic curvature or variation along a side edge would defeat a finding of infringement.
- Technical Questions: The infringement analysis will depend on factual evidence. What evidence does the complaint provide that the accused cases meet the specific height relationships required by the claims? While the complaint references figures of the accused products, the case will likely require precise measurements and expert testimony to establish whether, for example, the side walls are in fact "less than" the top walls, and whether the corners are "substantially equivalent" in height, as claimed.
V. Key Claim Terms for Construction
For the '319 Patent
- The Term: "substantially equivalent" (from Claim 14)
- Context and Importance: This term governs the relationship between the height of the corners and the height of the taller edge panels (e.g., top and bottom). Its construction is critical because it determines the degree of geometric precision required for infringement. Practitioners may focus on this term because it introduces ambiguity into an otherwise dimensional claim.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The use of "substantially" itself suggests that the patentee did not intend to require strict mathematical identity. The specification does not provide a numerical tolerance, which may support interpreting the term functionally, i.e., equivalent enough to achieve the stated purpose of protecting the screen.
- Evidence for a Narrower Interpretation: A defendant may argue that the figures, such as Fig. 1E-1H, depict corners that are visually indistinguishable in height from the top and bottom edges, suggesting an intent for the term to mean "nearly identical."
For the '524 Patent
- The Term: "only one height that continuously spans" (from Claim 1)
- Context and Importance: This limitation defines the profile of the side walls between the corner "transitions." Its definition is key to distinguishing the claimed shape from other designs that might have, for example, a convex or concave profile for grip.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: A plaintiff might argue this language simply means the edge section is of a constant height, without additional steps or tapers, and does not preclude minor, unintentional variations from the manufacturing process. The focus is on the absence of designed changes in height.
- Evidence for a Narrower Interpretation: A defendant could argue that "only one height" and "continuously" together require a perfectly straight, flat profile along that edge portion. Any intentional curvature or change, however slight, would mean the edge does not have "only one height." The claim's careful distinction between the constant-height "panels" and the changing-height "transitions" may support this stricter reading.
VI. Other Allegations
- Indirect Infringement: The complaint alleges Defendant infringes "directly or through its intermediaries" (Compl. ¶¶12, 19), but the counts are for direct infringement under 35 U.S.C. § 271(a). The complaint does not plead specific facts to support claims for induced or contributory infringement.
- Willful Infringement: The prayer for relief seeks a finding of willful infringement (Compl. p. 17, ¶c). However, the factual allegations in the body of the complaint do not mention pre-suit notice, knowledge of the patents, or other facts typically used to support a claim of willfulness.
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of claim construction: can Plaintiff convince the court to adopt a construction of terms like "substantially equivalent" that is broad enough to read on the physical structure of the accused cases, while can Defendant establish that precise geometric terms like "only one height that continuously spans" impose a strict standard that its products do not meet?
- A key evidentiary question will be one of factual proof: assuming a given claim construction, the dispute will turn on whether Plaintiff can present sufficient factual evidence—likely through expert analysis and physical measurements—to demonstrate that the multitude of accused VRS Design cases possess the specific, multi-part height relationships and transition geometries required by the asserted claims.
