Molecular Rebar Design, LLC (as patent owner) and its subsidiary Black Diamond Structures, LLC (as exclusive licensee) have sued LG Energy Solution (2:24-cv-00107) and Samsung (2:24-cv-00108) in separate Eastern District of Texas complaints. Asserted in each complaint are five patents generally related to lithium-ion batteries based on “discrete carbon nanotubes (‘CNTs’)”, which are, per the plaintiff, “substantially disentangled, unlike typical CNTs, which are clumped and clustered”. The accused products include certain batteries (e.g., “the LG HG2 battery, HG6 battery, and MJ1 battery”) and Samsung smartphones (e.g., “the Samsung Galaxy S9, Samsung Galaxy S10+, Samsung Galaxy S21 Ultra, and Samsung Galaxy S22 Ultra”).
