Chip design company Cadence has lost a chunk of its legal battle against Avant, according to US reports. Cadence had alleged that Avant thefted its trade secrets, but now a US judge has ruled that a 1994 waiver meant there was no case to answer before that time. But the judge said that Cadence, if it so wishes, can pursue the matter after the 1994 waiver. That will make the lawyers happy, as it is likely Cadence will continue this part of the case. ®
