In February 1970, [[Larry D. Nichols]] invented a 2×2×2 "Puzzle with Pieces Rotatable in Groups" and filed a Canadian patent application for it. Nichols's cube was held together with magnets. Nichols was granted {{US patent|3655201}} on April 11, 1972, two years before Rubik invented the [[Rubik's Cube|3×3×3 cube]].

Nichols assigned his [[patent]] to his employer Moleculon Research Corp., which sued [[Ideal Toy Company|Ideal]] in 1982. In 1984, Ideal lost the patent infringement suit and appealed. In 1986, the appeals court affirmed the judgment that Rubik's 2×2×2 Pocket Cube infringed Nichols's patent, but overturned the judgment on Rubik's 3×3×3 Cube.<ref>{{cite web|url=http://digital-law-online.info/cases/229PQ805.htm |title=Moleculon Research Corporation v.
