MYW Semitech LLC

MYW Semitech, LLC is a privately held entity that appears to operate as a Non-Practicing Entity (NPE), also known as a patent assertion entity. The company's legal domicile is in Delaware, though no operational headquarters, founding date, employee count, or revenue figures are publicly available. In its ongoing litigation, Davidson Kempner Capital Management LP and Piccadilly Patent Funding LLC are listed as participants, indicating third-party litigation funding.

MYW Semitech, LLC does not publicly offer products or services. Instead, it asserts a portfolio of patents primarily focused on advanced semiconductor chip packaging technology. These patents describe innovations in "fan-out chip packaging," which involves structures built upon polymer or solid layers with copper plugs designed for high-density interconnections in miniaturized electronic devices. The patent portfolio tracked by an AI litigation platform is noted to consist of eight patents within the semiconductor and optics technology center.

The company's litigation posture is that of a patent enforcer, evidenced by its role as a plaintiff in patent infringement suits. The provided case data shows one plaintiff case and one defendant case. The plaintiff case, MYW Semitech, LLC v. Apple Inc., was filed in the Delaware District Court, a common venue for patent litigation. The defendant case against MYW Semitech, LLC was initiated by Unified Patents, LLC at the Patent Trial and Appeal Board (PTAB), an action typically taken by Unified Patents against NPEs to challenge patent validity.

The most prominent tracked case is MYW Semitech, LLC v. Apple Inc., filed on April 24, 2025. This suit alleges infringement of three patents related to chip package technology by Apple's A-series and S-series processors. In January 2026, the Delaware District Court denied Apple's motion for a pre-institution stay pending an Inter Partes Review (IPR) related to the patents-in-suit.
