LS Cable & System Ltd. v. Apple Inc.

LS Cable & System Ltd. has initiated a patent infringement lawsuit against Apple Inc. in the United States District Court for the Northern District of California, case number 3:24-cv-09194. The plaintiff, LS Cable & System Ltd., is a South Korea-based industrial corporation and a global manufacturer of power and telecommunication cables, which expanded into wireless power transfer technology in the mid-2000s, indicating its role as an operating company rather than a non-practicing entity. The defendant, Apple Inc., is a major American multinational technology company known for its consumer electronics, software, and online services, including its popular iPhone, Apple Watch, and AirPods product lines.

The core of the dispute revolves around U.S. Patent No. 8,013,568, titled "Contact-less chargeable battery and charging device, battery charging set, and charging control method thereof." This patent describes a wireless charging system for mobile communication terminals that utilizes electromagnetic induction and includes a charging power adjusting unit. This unit wirelessly receives monitoring results from the battery to precisely adjust the transmitted charging power, notably by intermittently applying a high-frequency alternating current to prevent signal screening. LS Cable alleges that Apple's products, specifically iPhones, Apple Watches, and AirPods, infringe this patent through their incorporation of wireless charging chips that support the Qi standard.

Filed on December 19, 2024, the case is currently ongoing before the Honorable Judge James Donato in the Northern District of California, a venue frequently chosen for patent disputes against major technology companies due to its proximity to Silicon Valley. The litigation is notable for its direct linkage to a prior ex parte reexamination (EPR) of the '568 patent, which LS Cable proactively sought in March 2021, resulting in amendments and new claims. LS Cable asserts willful infringement by Apple beginning in September 2023, following the issuance of the reexamination certificate. This case highlights the commercial significance of wireless charging technology in the consumer electronics market and the strategic use of USPTO reexamination proceedings in preparation for enforcement.

The user is asking for a chronological list of key legal developments and outcomes in the patent infringement case of LS Cable & System Ltd. v. Apple Inc., focusing on various litigation stages and any parallel PTAB proceedings. I need to search for docket information, court orders, and news related to this case to compile the requested details.

Here's a plan:

1. Verify Filing Date and Initial Pleadings: Confirm the complaint filing date and search for Apple's answer and any counterclaims.
2. Pre-trial Motions: Look for any motions to dismiss, transfer, or stay pending IPR. Given the case was filed in late 2024, it's relatively early, so summary judgment or trial events are unlikely to have occurred yet.
3. Claim Construction (Markman): Check if a Markman hearing has been scheduled or held.
4. Discovery: Look for any significant discovery orders or disputes.
5. Trial/Verdict/Post-trial: Highly unlikely at this stage, but I'll confirm.
6. Settlement/Dismissal/Appeal: Unlikely to be final at this stage, but I'll check for any early dispositions.
7. Parallel PTAB Proceedings: Search for any Inter Partes Reviews (IPRs) or Post-Grant Reviews (PGRs) related to U.S. Patent No. 8,013,568, and their status and impact on the district court case. The previous section mentioned an ex parte reexamination, so I will focus on finding any new IPRs initiated by Apple.

Let's start by looking for the PACER docket or reliable legal news sources that summarize the early stages of the case.The following outlines the key legal developments and outcomes in LS Cable & System Ltd. v. Apple Inc., Case No. 3:24-cv-09194, as of May 19, 2026:
