Longitude Licensing Limited et al. v. Apple Inc. et al.

Case Overview and Background: Longitude Licensing Limited et al. v. Apple Inc. et al. (337-TA-1443)

This case is a patent infringement investigation initiated by Longitude Licensing Limited and Marlin Semiconductor Limited, subsidiaries of patent monetization firm IPValue Management, against a host of major technology companies before the U.S. International Trade Commission (USITC). The complainants, operating as Non-Practicing Entities (NPEs) or Patent Assertion Entities (PAEs), specialize in acquiring and licensing significant patent portfolios from technology companies. Marlin Semiconductor specifically acquired the asserted patent portfolio from United Microelectronics Corporation (UMC), a Taiwanese semiconductor foundry.

The accused products are "certain foreign-fabricated semiconductor devices, products containing the same, and components thereof." This broadly encompasses non-x86 semiconductor devices manufactured using Taiwan Semiconductor Manufacturing Company (TSMC)'s 7 nm and smaller process nodes outside the United States. The investigation targets devices such as semiconductor wafers and dies, as well as end products containing these components, including smartphones, tablets, personal computers, smartwatches, network units, standalone integrated circuits, and circuit boards. The defendants include prominent global players: Apple Inc., Broadcom Inc., Lenovo (including specific Lenovo entities), Motorola Mobile Communication Technology Ltd., Motorola (Wuhan) Mobility Technologies Communication Company Limited, OnePlus Technology (Shenzhen) Co., LTD., Taiwan Semiconductor Manufacturing Company Limited (TSMC), and Qualcomm Inc.

The investigation, designated 337-TA-1443, is before the U.S. International Trade Commission. An Administrative Law Judge (ALJ), whose specific name is not publicly confirmed in the available search results, has been assigned to preside over the case. The USITC is a crucial venue for patent disputes due to its expedited proceedings, which typically conclude within 15-18 months from complaint to final ruling, significantly faster than federal district court litigation. The primary remedy available at the ITC is an exclusion order, which can bar infringing imported products from entering the U United States, along with cease and desist orders against domestic inventories. Unlike district courts, the ITC cannot award monetary damages. For this investigation, an evidentiary hearing took place in February 2026, with an Initial Determination expected in May 2026 and a Final Determination by September 2026.

This case is notable for several reasons. It exemplifies a common NPE assertion strategy where patents acquired from a major operating company (UMC) are asserted against multiple high-profile technology companies in critical industry sectors, particularly advanced semiconductors and consumer electronics. The litigation strategy also includes parallel district court cases against some of the same defendants in the Western and Eastern Districts of Texas, which have been stayed pending the ITC outcome, a tactic often employed to seek both injunctive relief (ITC) and monetary damages (district court). The targeting of advanced semiconductor nodes (7nm and smaller) from TSMC underscores the high-value technology at the heart of the dispute and its potential impact across the global electronics supply chain.

The user wants a chronological list of key legal developments and outcomes for the ITC investigation 337-TA-1443. I need to cover various stages of litigation including filing, pre-trial motions, claim construction, discovery, trial, and final disposition, as well as any parallel PTAB proceedings.

I will use web search to find docket entries, rulings, and news articles related to 337-TA-1443. I will pay close attention to dates to ensure chronological order.

Here's a plan:

1. Filing & initial pleadings: Look for the complaint filing date and initial responses from defendants.
2. Pre-trial motions: Search for motions to dismiss, transfer, stay, or for summary judgment.
3. Claim construction (Markman): Determine if a Markman hearing or ruling occurred and its date/outcome.
4. Discovery: Look for any notable discovery disputes or milestones, although these might be less public for ITC cases.
5. Trial events: The previous section states an evidentiary hearing occurred in February 2026. I need to confirm this and look for any details.
6. Verdict/Post-trial: The previous section mentions an Initial Determination (ID) expected in May 2026. I need to check if it has been issued.
7. Settlement, dismissal, judgment, appeal: Check for any final dispositions or appeals.
8. Parallel PTAB IPR/PGR: Search for IPRs or PGRs filed against patent 8076194, which is the patent at issue.

Given today's date (2026-05-29) and the expected Initial Determination in May 2026, I should specifically look for news or official releases regarding that ID.Key Legal Developments and Outcome for Longitude Licensing Limited et al. v. Apple Inc. et al. (337-TA-1443)
