As it turns out, Korea operates two separate trademark systems for hardware and software. So while this doesn't affect Android OS and its distribution, Samsung's recent acquisition of the Android hardware trademark does forbid other manufacturers from releasing Android-branded devices -- whether they be a mobile phone, a PMP, PDA, GPS, DMB, or any other snappily titled mobile computer -- into the Korean market. This will be felt by local competitors like LG, who has an Andro-1 OEM handset in the works that would infringe Samsung's newfound rights. The trademark previously belonged to local supplier Triplex, who'd held it since before Google's OS came into being, and apparently using just four characters of "Android" will be sufficient to offend the authorities. Sammy's clearly decided to aggressively pursue being the premier supplier of Android phones in its backyard, and rubbing LG's nose in it must've been the chocolate frosting atop that eclair.
