There was a lot of controversy when it was discovered that Nintendo had patented the 'summon character and let it fight' patent for the Pokemon franchise in the United States. Now it turns out that the boss of the patent office is now re-examining the patent after all the discourse which followed revealing the accepted patent. John A. Squires, who became director of the USPTO in September, is closely looking at the patent after he "determined that substantial new questions of patentability have arisen" to certain claims made by the patent.
