Following its settlements with six of the nine chipmakers it sued for infringing its memory chip patents, Texas Instruments is in line for very substantial royalties. It will take a pre-tax gain of $108m with its first quarter figures to reflect the $134m fixed payments already made by the six – Oki Electric, Matsushita, Mitsubishi, Toshiba, Sharp and Fujitsu, and says per-unit royalties between now and 1990 could exceed the $134m figure. Suits are still out against NEC, Hitachi and Samsung.
