In its ruling, the court determined that the microcode in the control store constitutes a computer program, and so is protected by copyright.

In late 1984, Intel again filed suit against NEC, claiming that the microcode in the V20 and V30 infringed its patents for the 8088 and 8086 processors. NEC software engineer
Hiroaki Kaneko had studied both the hardware design of the Intel CPUs and the original Intel microcode.
244:. In 1990, an upgrade to the fabrication process technology resulted in the V20H and V20HL, with improved performance and reduced power consumption. Later versions added speeds of 12 and 16 MHz. The V20HLs were also completely static, allowing their clock to be stopped.

In 1982, Intel sued NEC over the latter's μPD8086 and μPD8088. This suit was settled out of court, with NEC agreeing to license the designs from Intel.
