A Delaware judge has thrown out the last claim against Texas Instruments filed by Qualcomm in a licensing dispute.
Qualcomm asserted last year that TI had broken the terms of a cross-licensing agreement when it revealed some information about the deal.
In July, a Delaware Court ruled that TI's disclosures were not a material breach of the agreement. After dropping its claim for damages in August, Qualcomm filed a separate claim asking the judge to reconsider the ruling.
A finding of a material breach would have allowed Qualcomm to break the agreement, but the same court ruled again on Wednesday that the agreement must stand. This puts an end to the outstanding claims in the case, TI said.
However, Qualcomm plans to appeal the court's latest ruling, a spokeswoman said.
TI and Qualcomm have an agreement in which each company is entitled to intellectual property from the other, such as Qualcomm's CDMA (Code Division Multiple Access) technology or TI's DSP (digital signal processor) technology.
Qualcomm developed the CDMA mobile phone standard and TI would lose out on a significant amount of business if it was no longer able to manufacture chips for CDMA mobile phones.
