Case Overview
The Parties
⚖️ Plaintiff
A non-practicing entity (NPE) asserting patent rights related to inductive wireless charging technology. NPEs frequently leverage targeted patent portfolios against large technology manufacturers.
🛡️ Defendant
Requires little introduction. Its MagSafe charging system — reintroduced with the iPhone 12 series — represents a significant proprietary implementation of the Qi wireless charging specification.
The Patents at Issue
Two patents formed the foundation of Vampire Labs’ infringement claims. Both address core technical implementations relevant to Qi-compliant charging systems, making them directly applicable to Apple’s accused products.
- • U.S. Patent No. 8,575,917 B2 — covering inductive wireless charging technology
- • U.S. Patent No. 8,358,103 B2 — covering related wireless power transfer methods

The Verdict & Legal Analysis
Outcome: Joint Dismissal With Prejudice
On January 8, 2026, both parties filed a joint stipulation of dismissal with prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(ii). The court formally closed the case on January 9, 2026, directing the clerk to terminate all pending motions.
Critically, a dismissal with prejudice bars Vampire Labs from re-filing the same claims against Apple on these patents. No damages amount was publicly disclosed, and no injunctive relief was issued — both consistent with confidential settlement resolution. As the court’s closing order noted: “The court lost jurisdiction when the parties voluntarily dismissed the entire suit under Rule 41(a)(1)(A)(ii).” The dismissal required no judicial approval, self-executing upon filing.
Verdict Cause Analysis
The case was initiated as a straightforward patent infringement action. While no public record of claim construction rulings, summary judgment motions, or invalidity findings exists, the trajectory toward confidential resolution is instructive. NPE cases against large technology defendants frequently resolve through: licensing agreements, IPR petition threats or filings by defendants challenging patent validity, or claim construction risk assessment revealing potential non-infringement positions. Apple’s well-resourced defense team signals aggressive defense posturing, consistent with its historical approach.
Legal Significance
The with-prejudice nature of the dismissal is the most legally significant procedural outcome. Unlike a without-prejudice dismissal, this resolution provides Apple with finality — the specific asserted claims of U.S. 8,575,917 and U.S. 8,358,103 cannot be re-asserted against Apple by Vampire Labs. For patent holders, this underscores the permanent consequences of settlement structures and dismissal terms.
The parallel dismissal of the Anker case (1:24-cv-01378) on the same date suggests a unified settlement spanning the MagSafe accessory ecosystem — a notable licensing or resolution strategy by Vampire Labs.

The case asserted U.S. Patent No. 8,575,917 B2 and U.S. Patent No. 8,358,103 B2, both covering inductive wireless charging technology applicable to Qi-compliant devices.
Both parties filed a joint stipulation under Fed. R. Civ. P. 41(a)(1)(A)(ii) on January 8, 2026. A with-prejudice dismissal bars Vampire Labs from re-asserting these claims against Apple. The terms of any underlying settlement were not publicly disclosed.
It reinforces that Qi-compliant products remain active NPE assertion targets, and that multi-defendant ecosystem strategies — targeting both primary manufacturers and accessory makers — are an evolving assertion pattern in this technology space.
