Clean Room Defense
MacPherson was credited with pioneering the "clean room" defense when he represented NEC in an IP lawsuit against Intel in the early 1980s. In the suit, Intel alleged that NEC stole and infringed its programming in its microprocessors, or "microcode". To rebut this accusation, MacPherson gave an independent engineer the task of programming an IC (Integrated Circuit) to do the same thing as the NEC and Intel Chips, but cutting off all access to any previously written microcode - in other words, simulating clean room conditions. After the engineer completed the task, experts concluded that the similarities between the microcode was not because of copying but due to the intrinsic constraints of programming microcode.

Famous quotes containing the words clean, room and/or defense:
“There is a rhythm to the ending of a marriage just like the rhythm of a courtship—only backward. You try to start again but get into blaming over and over. Finally you are both worn out, exhausted, hopeless. Then lawyers are called in to pick clean the corpses. The death has occurred much earlier.”
—Erica Jong (b. 1942)
“In this world there’s room for everyone, and the good earth is rich and can provide for everyone. The way of life can be free and beautiful, but we have lost the way. Greed has poisoned men’s souls, has barricaded the world with hate, has goosestepped us into misery and bloodshed.”
—Charlie Chaplin (1889–1977)
“For he is the cleanest in the use of his forepaws of any quadruped.
For the dexterity of his defense is an instance of the love of God
to him exceedingly.”
—Christopher Smart (1722–1771)
