IV. Analysis of Infringement Allegations

’275 Patent Infringement Allegations

Claim Element (from Independent Claim 8) Alleged Infringing Functionality Complaint Citation Patent Citation
a docking system, comprising: a protective arrangement... The iPort Connect Pro system, which includes a protective case and a docking station. ¶38 col. 10:17-18
a docking connector comprising a socket receiver and a peripheral surface forming a support rim... The docking station comprises a connector that receives the case. ¶38 col. 15:25-30
wherein the socket receiver is recessed relative to the peripheral surface... The connector on the station is recessed to guide and align the case. ¶38, ¶43 col. 15:28-30
and a plurality of biasing, pogo pin docking contacts arranged in a single line and disposed along the socket receiver. The docking station's connector has a plurality of spring-loaded "pogo pin docking contacts" arranged in a single line to connect with the case. A product image highlights these as "CHARGING PINS." ¶43, p. 9 col. 8:40-42
  • Identified Points of Contention:
    • Scope Questions: A central question may be whether the accused "CHARGING PINS" meet the specific limitation of "biasing, pogo pin docking contacts" as recited in the claim. The defense may argue that their contacts are of a different type (e.g., leaf springs) or do not function as true "pogo pins."
    • Technical Questions: What evidence demonstrates that the accused contacts are "biasing"? While the complaint alleges they are "pogo pin" contacts, which are inherently biasing, the evidentiary basis for this technical characterization will be a key point of discovery and potential dispute (Compl. ¶43).

’458 Patent Infringement Allegations

Claim Element (from Independent Claim 12) Alleged Infringing Functionality Complaint Citation Patent Citation
a protective arrangement... comprising: a removable cover comprising a panel and a skirt that meets edges of the panel... The iPort Connect Phone case is a removable cover with a panel and skirt forming an interior cavity for an iPhone. ¶52 col. 10:1-3
an adapter comprising a male plug extending in a longitudinal direction into the interior cavity... The case includes an adapter with an internal plug (e.g., a Lightning connector) that extends into the case to mate with the iPhone's port. ¶53 col. 9:8-14
and a contactor opposite the male plug and configured for exposure through the adapter opening... The case has an external contactor with electrical contacts for docking. ¶53 col. 9:14-17
the contactor comprising a lateral surface recessed relative to the removable cover and a plurality of electrical contacts arranged on the lateral surface... The external contactor has a recessed lateral surface with multiple electrical contacts arranged on it. A product image shows these contacts on the bottom edge of the case. ¶54, p. 13 col. 10:48-52
wherein the longitudinal direction of the male plug is perpendicular to the lateral surface of the contactor. The complaint alleges that the internal plug extends into the phone (longitudinally) while the external contacts are on a lateral surface perpendicular to that direction. ¶54 col. 10:55-58
  • Identified Points of Contention:
    • Scope Questions: The construction of the geometric limitation "the longitudinal direction of the male plug is perpendicular to the lateral surface of the contactor" will be critical. The parties may dispute the proper reference axes and surfaces for measuring this perpendicular relationship on the accused product.
    • Technical Questions: Does the physical arrangement of the accused Connect Phone case actually satisfy the claim's strict perpendicularity requirement? Infringement analysis will likely involve detailed measurements and expert testimony on the spatial relationship between the internal Lightning plug and the external docking contacts.

V. Key Claim Terms for Construction

For the ’275 Patent

  • The Term: "biasing, pogo pin docking contacts" (Claim 8)
  • Context and Importance: This term recites a specific type of electrical contact. The infringement analysis for the docking system hinges on whether the accused station's "CHARGING PINS" fall within the scope of this term. Practitioners may focus on this term because it is highly specific and potentially distinguishable from other types of spring-loaded connectors.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The specification discusses docking connectors more broadly, including "biasing pogo pins or biasing leaf spring contacts" (’275 Patent, col. 8:40-42). Plaintiff may argue this context suggests "pogo pin" should not be read in an overly restrictive way that excludes functionally similar biasing contacts.
    • Evidence for a Narrower Interpretation: Defendant may argue that the explicit recitation of "pogo pin" in the claim, as opposed to the broader "biasing contacts" used elsewhere, was a deliberate choice to limit the claim to that specific, well-understood structure (a pin moving within a barrel).

For the ’458 Patent

  • The Term: "the longitudinal direction of the male plug is perpendicular to the lateral surface of the contactor" (Claim 12)
  • Context and Importance: This term defines a precise geometric relationship between the internal and external connectors of the adapter. The entire infringement case for the ’458 Patent may depend on whether the accused product's geometry meets this limitation.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: Plaintiff may point to figures like Figure 8, which shows a cross-section of an adapter where the internal plug (116) and external contactor (120) are oriented at roughly 90 degrees, to argue that the term should be interpreted functionally to cover arrangements that achieve a similar right-angle electrical pass-through (’458 Patent, Fig. 8).
    • Evidence for a Narrower Interpretation: Defendant may argue that "perpendicular" requires a strict 90-degree angle and that any deviation in the accused product, however slight, avoids infringement. They may also point to specific embodiments to argue for a narrow definition of the "lateral surface" and "longitudinal direction" reference frames.

VI. Other Allegations

  • Indirect Infringement: For all asserted patents, the complaint alleges inducement by providing the accused products with instructions and advertising their intended infringing use (e.g., Compl. ¶44, ¶55). It also alleges contributory infringement by supplying the cases and docks, which are alleged to be material components especially made for use in the patented system with no substantial non-infringing uses (e.g., Compl. ¶45, ¶56).
  • Willful Infringement: Willfulness is alleged for all six patents. The allegations are based on Defendant's alleged actual knowledge of the patents and their infringement following pre-suit notification letters sent on January 17, 2024 (for the ’275 and ’458 patents) and November 1, 2024 (for the remaining four patents) (Compl. ¶47, ¶58, ¶68, ¶80, ¶93, ¶106).

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

  • A core issue will be one of claim construction and technical specificity: can the specific structural limitations in the claims, such as "biasing, pogo pin docking contacts arranged in a single line" (’275 Patent) and the precise "perpendicular" geometric relationship between connectors (’458 Patent), be read to cover the accused iPort products, or do these terms create a narrow scope that the products do not meet?
  • A second key question will be evidentiary: what technical evidence will be presented to prove that the accused products function as alleged? For instance, does the accused station use components that are technically "pogo pins," and does the accused phone case exhibit the strict perpendicular geometry required by the claims, issues that are asserted in the complaint with marketing and instructional diagrams?
  • A final dispositive issue may be the scope of the system claims (e.g., ’142 Patent), which will require Plaintiff to prove infringement by a combination of instrumentalities—the protective case and the multi-device docking station. The case will require evidence that these components are made, used, or sold together in an infringing manner.
