"The Rubik's Magic Cube was first released to Budapest toy shops in 1980. The progress of the Cube towards the toy shop shelves of the West was then briefly halted so that it could be manufactured to Western safety and packaging specifications. A lighter Cube was produced, and Ideal Toys decided to rename it. \"The Gordian Knot\" and \"Inca Gold\" were considered, but the company finally decided on \"Rubik's Cube\", and the first batch was exported from Hungary in May 1980."@en . . .

Taking advantage of an initial shortage of Cubes, many cheap imitations appeared. In 1994, Ideal lost a patent infringement suit by Larry Nichols for his US patent #3655201. Terutoshi Ishigi acquired Japanese patent JP55\u20128192 for a nearly identical mechanism while Rubik's patent was being processed, but Ishigi is generally credited with an independent reinvention."@en .
