Opti, a US chip-related intellectual property company?has accused AMD of infringing three of its patents, all centering on techniques microprocessors can use to predict cache memory access requirements. Apparently this is not the first time Opti has played this game, they filed a similar complaint against Nvidia two years ago.

The three patents at issue are US patents 5,710,906, 5,813,036 and 6,405,291, all entitled "Predictive Snooping of Cache Memory for Master-Initiated Accesses". The first two patents were awarded in 1998, the third in 2002. The later patents represent continuations of the first one.
