Case Timeline

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 “`’319` Patent”).

The Invention Explained

• Problem Addressed: The patent describes a problem with then-existing protective cases for electronic devices like smartphones, noting they are often "bulky, unsightly, and can limit access to the device screen or control buttons" (’319 Patent, col. 1:18-22).
• The Patented Solution: The invention is a protective case, often with a rigid inner layer and a resilient outer layer, that features a non-uniform height around its perimeter. The portions of the case along the top and bottom edges are raised to a "first height" to lift the screen off a flat surface, while the portions along the side edges have a lower "second height" to allow users unimpeded access for actions like "finger-swiping, icon selection, and other actions" near the screen's edge (’319 Patent, col. 5:40-56; Fig. 1F). This design seeks to provide screen protection without sacrificing usability.
• Technical Importance: The described approach addresses a fundamental trade-off in case design: maximizing protection against drops and surface scratches while minimizing interference with the user's interaction with an increasingly borderless touchscreen.

Key Claims at a Glance

• The complaint asserts independent claims 8 and 14.
• Independent Claim 8 requires, among other things:
  • A first panel with a large, centrally positioned opening.
  • Four edge panels to envelop a portion of an electronic device.
  • The four edge panels comprising different heights.
  • A first pair of edge panels comprising a "first height" substantially similar to the height of the device's edges.
  • At least a portion of a second pair of edge panels comprising a "second height" less than the first height.
• Independent Claim 14 requires, among other things:
  • A first panel with a large, centrally positioned opening and at least four edge panels.
  • A first, second, third, and fourth corner at each intersection of the edge panels.
  • At least two of the four edge panels comprising a "first height."
  • The four corners comprising a "second height" substantially equivalent to the first height.
  • At least a portion of the other two of the four edge panels comprising a "third height" less than the first and second height.
• The complaint asserts dependent claims 9, 12, and 13 (depending from claim 8) and 15, 18, and 19 (depending from claim 14) (Compl. ¶9).

III. The Accused Instrumentality

Product Identification

• The accused instrumentalities are various models of Seidio-branded protective cases, including the Dilex, Dilex - Kryptek, Executive, Optik, Provectus, Surface, and Dilex Pro lines, designed for a range of Samsung Galaxy smartphones (Compl. p. 4). The complaint presents a table listing specific case models matched to specific phone models. (Compl. p. 4).

Functionality and Market Context

• The complaint alleges that the accused cases are for an electronic device and include features corresponding to the elements of the asserted claims (Compl. ¶¶10, 14). Specifically, the complaint alleges the cases have a "first panel having a large centralized opening (e.g., opening for the rear camera)" and "four edge panels (e.g., walls to envelope a smartphone)" where the side walls are shorter than the top and bottom walls (Compl. ¶10). The complaint does not provide detail on the market context of the accused products.

IV. Analysis of Infringement Allegations

The infringement allegations are presented in narrative form. The complaint repeatedly cites Figures 1-11 of the patent itself as evidence of infringement by the accused products (Compl. ¶¶10-17).

’319 Patent Infringement Allegations (Claim 8)

’319 Patent Infringement Allegations (Claim 14)

• Identified Points of Contention:
  • Technical Questions: A central question will be whether the accused products embody the specific height differentials required by the claims. For Claim 14, the complaint must establish not just two different heights (sides vs. top/bottom), but a specific three-height structure: (1) top/bottom edges, (2) corners, and (3) center of the side edges. The complaint's allegation that "the center of the side walls are of a shorter height" suggests an attempt to read on this limitation, but it provides no specific measurements or product analysis (Compl. ¶14).
  • Evidentiary Questions: The complaint's exclusive reliance on the patent’s own figures to illustrate the alleged infringement, rather than providing photographs or diagrams of the accused products, raises the question of whether the pleading contains sufficient factual matter, accepted as true, to state a plausible claim for relief (Compl. ¶¶10-17). The court may need to determine if these conclusory allegations tied to the patent's own drawings, rather than facts about the accused products, are sufficient.

V. Key Claim Terms for Construction

• The Term: "first height," "second height," "third height" and relational terms like "less than"

• Context and Importance: These relative height terms are the central feature of the asserted claims. The entire infringement analysis hinges on whether the accused cases possess the specific multi-level height structure defined by these terms. Practitioners may focus on these terms because their construction will determine the scope of protection and whether minor variations in case geometry fall inside or outside the claims.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification describes the height difference functionally, stating the greater height H at the top and bottom "allow the smartphone display to be raised from a surface" while the reduced height h at the sides "allows the screen to be completely accessed by the user" (’319 Patent, col. 5:48-53). A party could argue any height difference sufficient to achieve this dual function meets the limitation.
  • Evidence for a Narrower Interpretation: The figures, such as Figure 1F, depict a distinct and visually apparent difference between height 'H' and height 'h' (’319 Patent, Fig. 1F). A party could argue that the term "less than" requires a non-trivial, functionally significant difference in height, not a minor or incidental manufacturing variance.

• The Term: "taper"

• Context and Importance: This term appears in asserted dependent claims 9 and 15. The complaint alleges a taper exists between the side walls and top/bottom walls (Compl. ¶¶11, 15). The patent specification distinguishes between a "smooth transition" and a "step" between different height sections (’319 Patent, col. 5:60-62). The definition of "taper" will be critical to determining infringement of these dependent claims.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The word "taper" is not explicitly defined, which may support giving it a plain and ordinary meaning of a gradual diminishing of thickness or width.
  • Evidence for a Narrower Interpretation: The specification’s explicit mention of both a "smooth transition" and a "step" as alternative embodiments could be used to argue that "taper" should be construed as the "smooth transition" and is distinct from an abrupt change in height, potentially narrowing its scope.

VI. Other Allegations

• Willful Infringement: The complaint does not contain allegations of willful infringement. It requests that the court declare the case "exceptional" and award attorneys' fees pursuant to 35 U.S.C. § 285, but it does not plead any specific facts to support this request (Compl. p. 7, ¶d).

VII. Analyst’s Conclusion: Key Questions for the Case

• A core issue will be one of claim construction and scope: How much of a height difference is required for a "second height" to be "less than" a "first height"? The case may turn on whether the court adopts a purely functional definition based on the patent's stated purpose or requires a more quantitatively or visually significant difference as depicted in the patent's figures.
• A key evidentiary question will be one of factual sufficiency: Does the complaint's infringement theory, which relies on conclusory statements and citations to the patent's own drawings rather than evidence from the accused products, meet the plausibility standard for pleading? The dispute will likely focus on whether discovery reveals that the physical structure of the Seidio cases maps onto the specific multi-height limitations of the asserted claims, particularly the three-tiered height structure of claim 14.
