Samsung is facing a legal challenge in the US that targets the core foundation of its foldable smartphone lineup. In a federal court in Texas, a relatively small firm, Lepton Computing, has filed a patent infringement lawsuit accusing Samsung of using its core foldable technology. The complaint claims that Samsung’s Galaxy Z Fold and Galaxy Z Flip series violate nine patents owned by Lepton. The allegation also extends to Samsung’s TriFold device.
SurveyWhat makes the case notable is how broad these claims are. Lepton says its patents cover essential parts of foldable phones, such as the hinge, sensors and the apps that transition between inner and outer displays. It also includes how hardware like cameras, magnets and speakers are arranged inside a folding body. In effect, the company is arguing that it built the core blueprint for foldable smartphones.

However, the timeline presents a challenge for Lepton’s case. According to a report by Seoul Wire (via Android Authority), the earliest of the nine patents was registered in June 2021. This is nearly two years after Samsung launched its first foldable phone in 2019. That gap could make it harder to prove that Samsung copied technology that was officially patented later. Lepton appears to be known about this gap as it has not included Samsung’s earliest foldable models in the lawsuit.
Lepton is seeking a permanent injunction on Samsung’s foldable phones in the US, along with damages, royalties and treble damages for alleged willful infringement. Samsung has not yet responded publicly to the lawsuit.
