These models confirmed the feasibility of Nichols' conception, but lacked durability. His efforts to conceive of a feasible mechanical means of assembly proved more difficult however, by the Fall of 1957, Nichols believed that a double tongue-in-groove arrangement could be made to work.ĭuring the period 1957-1968, Nichols constructed several models of his puzzle, making cubes of heavy file-card type paper and affixing small magnets to the inside of the small cubes. Nichols very quickly realized that magnets could be used to hold the cubes in assembled form yet allow rotational movement. He felt immediate satisfaction at having arrived at this concept. He recognized that the smaller cubes would be rotated in sets of four around one of three mutually perpendicular axes. Nichols quickly envisioned an assembly of eight cubes *1423 stacked in a 2 × 2 × 2 arrangement, with each of the six faces of the composite cube distinguished by a different color. In particular he, considered various ways of eliminating the empty space, while allowing pieces to be moved.ĭuring an evening stroll in the Summer of 1957, these thoughts and ideas suddenly fell into place in Nichols' mind and he conceived of a three-dimensional puzzle capable of rotational movement. His interest in the familiar "Sam Loyd 15" puzzle evolved into a desire to improve on what he perceived to be its shortcomings. Nichols' interest in puzzles began at the age of five or six. This opinion constitutes my findings of fact and conclusions of law with respect to validity and infringement.
ROTATE OBJECTS IN GAME CORP DX TRIAL
The issues relating to damages and other possible relief were severed and a trial was held on the issues of validity and infringement. The subject of the '201 patent, in its preferred embodiment, is a cube puzzle composed of eight smaller cublets that may be rotated in groups of four adjacent cubes, and a method by which the sets of cubes may be rotated, first to randomize, and then to restore a predetermined pattern on the six faces of the composite cube. ("CBS"), as the successor to the Ideal Toy Corporation ("Ideal"), with infringement of Claims 3, 4, 5, 6 and 9 of the '201 patent. Moleculon charges the defendant, CBS, Inc. This is an action for patent infringement brought by the plaintiff, Moleculon Research Corporation ("Moleculon"), as assignee of U.S. Dunlavey, Los Angeles, Cal., for defendant. Barrett, Eslinger & Pelton, New York City, Dean C. Pepperman, II, Morris, Nichols, Arsht & Tunnell, Wilmington, Del., Lewis H. Brown Morton, Jr., Warsaw, Va., for plaintiff.
