Lepton Computing LLC

Lepton Computing LLC is a private U.S. company that has been described as having a minimal public presence and as few as two employees. According to its own statements, the company has been developing technology related to foldable and flexible display mobile devices since 2008. Financial details such as revenue and funding are not publicly available. While its website mentions an address in Morris Ave [Building A], Brooklyn, NY, some legal commentators note its corporate structure and lack of a commercial product line are characteristic of a Non-Practicing Entity (NPE).

Lepton Computing does not manufacture or sell any commercial products. The company's primary activity centers on asserting its patent portfolio, which it claims consists of over 50 U.S. and international patents. The portfolio is described as foundational to the foldable device industry, covering technologies such as hinge mechanisms, display protection, software for multitasking, and "app continuity" features that allow applications to transition between screens when a device is folded or unfolded. Lepton states it built several prototypes, including one called the "Lepton Flex," to develop this intellectual property.

As reflected in the provided case data, Lepton Computing acts exclusively as a plaintiff in patent litigation. The company has filed all three of its tracked lawsuits in the U.S. District Court for the Eastern District of Texas, a venue known for patent cases. This litigation posture, with three plaintiff cases and zero defendant cases, is consistent with the business model of an NPE, which enforces patents rather than defending its own products in the market.

Lepton's notable legal actions are its April 2026 lawsuits against Samsung Electronics Co., Ltd. and its U.S. subsidiary. In these cases, Lepton alleges that Samsung's Galaxy Z Fold and Z Flip product lines infringe on nine of its patents. Lepton claims it had discussions with Samsung about potential collaboration as early as 2013, during which it shared technical details and prototypes. The lawsuits seek monetary damages and a permanent injunction on the sale of Samsung's foldable devices in the U.S. Some reports have noted that the earliest registration date for the asserted patents is in 2021, two years after Samsung launched its first commercial foldable phone.
