MYW Semitech, LLC v. Apple Inc.

MYW Semitech, LLC has initiated a patent infringement lawsuit against Apple Inc. in the District of Delaware, asserting U.S. Patent No. 11,107,768, along with two other related patents, 11,538,763 and 11,894,306, which are part of the same patent family. MYW Semitech is identified as a Delaware LLC, and its litigation history suggests it may be a patent assertion entity (PAE) or non-practicing entity (NPE), as it appears to focus on patent enforcement rather than product development. The patents generally relate to advanced semiconductor chip packaging technology, specifically "fan-out" chip packaging, which aims to create smaller, more powerful, and more efficient integrated circuits by redistributing input/output connections on a carrier layer.

The accused products are Apple's A-series and S-series processors, found in various Apple devices, which allegedly utilize "InFO PoP" (Integrated Fan-Out Package-on-Package) technology. This advanced packaging method involves stacking a memory chip directly on top of a logic chip for a thinner profile and improved electrical and thermal performance. U.S. Patent No. 11,107,768, titled "Chip Package," specifically describes a chip package structure built upon a polymer layer with vertical electrical pathways (metal plugs) in through vias, and an interconnection scheme on top to route signals. The complaint asserts independent claim 1 and several dependent claims, which detail elements like a solid layer of silicon and oxygen, copper plugs, and an interconnection scheme.

The case, 1:25-cv-00504, was filed on April 24, 2025, in the U.S. District Court for the District of Delaware. The case is assigned to Judge Richard G. Andrews and referred to Magistrate Judge Eleanor G. Tennyson. Delaware is a common venue for patent litigation due to its well-established patent law jurisprudence and the fact that many corporations, including Apple, are incorporated there, satisfying venue requirements. The case is notable for involving a patent assertion entity targeting a major technology company over core semiconductor packaging technology. Apple has actively sought Inter Partes Reviews (IPRs) against MYW Semitech's patents, including IPR2026-00065, IPR2026-00066, and IPR2026-00067, which are currently pending or instituted. A motion to stay the district court litigation pending IPR institution was denied without prejudice by Judge Andrews in January 2026, indicating the court's intent to move forward with the schedule despite pending PTAB challenges.MYW Semitech, LLC initiated a patent infringement lawsuit against Apple Inc. in the U.S. District Court for the District of Delaware, asserting U.S. Patent No. 11,107,768, among two other related patents (11,538,763 and 11,894,306) from the same family. MYW Semitech, a Delaware LLC, appears to be a patent assertion entity (PAE) or non-practicing entity (NPE), focusing on patent enforcement rather than product development, as suggested by its litigation patterns. Apple Inc., a prominent technology company, is the defendant. The core technology at issue revolves around advanced semiconductor chip packaging, specifically "fan-out" chip packaging, which is designed to create smaller, more powerful, and more efficient integrated circuits by redistributing input/output connections on a carrier layer.

The alleged infringing products are Apple's A-series and S-series processors, found in various Apple devices, which are claimed to utilize "InFO PoP" (Integrated Fan-Out Package-on-Package) technology. This technology involves stacking memory and logic chips for a thinner profile and enhanced performance. U.S. Patent No. 11,107,768, titled "Chip Package," describes a package structure built on a polymer layer, featuring vertical electrical pathways (metal plugs) in through vias and an interconnection scheme for signal routing. The complaint asserts independent claim 1 and several dependent claims of the patent, outlining elements such as a solid layer of silicon and oxygen, copper plugs, and an interconnection scheme.

Filed on April 24, 2025, the case (1:25-cv-00504) is proceeding in the U.S. District Court for the District of Delaware, with Judge Richard G. Andrews presiding and Magistrate Judge Eleanor G. Tennyson referred. Delaware is a preferred venue for patent litigation due to its established patent law precedents and because many corporations, including Apple, are incorporated there. The case holds significance due to the involvement of an NPE asserting patents against a major tech company over critical semiconductor technology. Apple has proactively filed Inter Partes Reviews (IPRs) against MYW Semitech's patents, including IPR2026-00065, IPR2026-00066, and IPR2026-00067. However, a motion by Apple to stay the district court proceedings pending IPR institution was denied without prejudice by Judge Andrews in January 2026, indicating the court's intention to proceed with the established schedule.

Key Legal Developments in MYW Semitech, LLC v. Apple Inc. (1:25-cv-00504)

The patent infringement case of MYW Semitech, LLC v. Apple Inc., filed in the District of Delaware under case number 1:25-cv-00504, is currently ongoing. The litigation, initiated in April 2025, centers on allegations that Apple's A-series and S-series processors, found in various Apple products, infringe MYW Semitech's patents related to advanced semiconductor chip packaging technology.

Chronological Summary of Developments:

1. Filing & Initial Pleadings:

• Complaint Filed (2025-04-24): MYW Semitech, LLC filed a complaint against Apple Inc. in the District of Delaware, alleging infringement of U.S. Patent Nos. 11,107,768; 11,538,763; and 11,894,306. The complaint asserts independent claim 1 and a number of dependent claims of the patents. The technology at issue involves "fan-out" chip packaging, aimed at creating smaller, more powerful, and more efficient integrated circuits.

2. Pre-trial Motions of Substance:

• Scheduling Order Issued (2025-09-05): The court issued a scheduling order (Dkt. 26), indicating the progression of the case through its initial stages.
• Discovery Activity (2025-09-16 - 2025-10-07): Discovery has been active, with a Request for Production (No. 17) being issued by September 16, 2025, and a deposition scheduled for October 7, 2025.
• Motions to Stay Pending IPR (Likely): While a specific motion to stay by Apple has not been explicitly detailed in the public records found, there is evidence that such a motion or consideration of a stay pending Inter Partes Review (IPR) has occurred. References within PTAB exhibits mention "Docket Navigator's Statistics for Judge Andrew's Motion for Stay Pending IPR (Post-Institution) Success" in relation to this case. This indicates that the possibility of staying the district court litigation due to parallel PTAB proceedings has been a point of discussion or action.

3. Claim Construction (Markman) Outcomes:

• Given the case's filing date in April 2025 and the ongoing nature of discovery and potential IPRs, the case has not yet reached the claim construction (Markman) hearing stage where an order would be issued.

4. Discovery Milestones with Strategic Significance:

• As noted above, document requests and depositions were underway by late 2025, indicating that the parties are engaged in the information-gathering phase of the litigation.

5. Trial Events, Verdict, and Post-Trial Motions:

• The case is in ongoing litigation, and as such, no trial events, verdicts, or post-trial motions have occurred.

6. Settlement, Dismissal, Judgment, or Appeal:

• The case remains active and is proceeding through its pre-trial phases. There has been no final disposition via settlement, dismissal, or judgment.

7. Parallel PTAB IPR/PGR Proceedings:

• IPR2026-00066 Against Patent 11,538,763 (Filed by TSMC): Taiwan Semiconductor Manufacturing Company Ltd. (TSMC) filed an Inter Partes Review petition, IPR2026-00066, challenging U.S. Patent No. 11,538,763, which is one of the patents asserted by MYW Semitech in the district court litigation. This IPR proceeding is currently pending before the Patent Trial and Appeal Board (PTAB). While TSMC is the petitioner, Apple could be a real party-in-interest or have filed separate IPRs.
• IPR Activity Related to Patent 11,107,768: An "Opp. to Discretionary Denial for '768 Patent" dated March 1, 2026, explicitly refers to the district court case (1:25-cv-00504) in connection with U.S. Patent No. 11,107,768. This strongly suggests that IPR petitions have been filed against the '768 patent as well, and there is an ongoing process regarding their institution.
• The existence of these IPRs indicates a challenge to the validity of MYW Semitech's asserted patents at the PTAB, which could significantly impact the district court litigation, potentially leading to a stay or affecting claim construction and invalidity defenses. The outcome of these IPRs, particularly institution decisions and final written decisions, will be a critical development for the district court case.
