As late as the early 1990s, IBM was winning millions of dollars from settling BIOS copyright infringement lawsuits against some other PC clone manufacturers like Matsushita/Panasonic (1987) and Kyocera (1993–1994), although the latter suit was for infringements between 1985 and 1990.
早在20世纪90年代初，IBM就从向其他PC克隆制造商（例如Matsushita/松下(1987)和京瓷 (1993-1994)）解决BIOS版权的侵权诉讼中赢获了数百万美元，不过后一项诉讼是就1985年至1990年之间的侵权行为。
