History
Dahon sent one of their employees to the U.K. to negotiate rights to manufacture the Brompton. Instead the employee formed Neobike and acquired the rights for his new company. Dahon holds several patents that are violated by Neobike's products, including the Brompton, and hence efforts by companies in the U.S. to import other Neobikes (not the Brompton which Neobike can't ship to the U.S. as part of their contract with Brompton) have been thwarted.
