Date: 24 June 1982 16:28-EDT From: Richard Pavelle Subject: Moleculon vs Ideal, cont. To: CUBE-LOVERS at MIT-MC I have read the patent of Larry Nichols who assigned it to Moleculon and it looks to me like they have a very strong case against Ideal. One should keep in mind, however, that more than 70% of patent infringement cases go against the patentee. The basic drawings and descriptions in the patent deal with the 2^3 held together (non-rigidly) by magnets. Nichols discusses the possibility of fixing the cubies rigidly in his description in a manner not unlike Rubik. But the fact that he does not mention this aspect in his claims may be his undoing. He mainly stresses the magnetic attachment. I would not be surprised if the PTO told him that the rigid attachment would comprise another implementation and he wished to avoid the extra expense (I am speaking from experience here). He discusses the puzzle aspects and some of the higher order cubes and non-cubes we have seen on the market. In conclusion, I doubt he will get his 60M from Ideal but I think he will get a non-trivial percentage and a continuing royalty.
