Broadcom has filed an anti-trust lawsuit against larger mobile phone-chip rival Qualcomm, claiming it is unfairly using its licensing business to promote its technology.
Broadcom had previously filed lawsuits against Qualcomm over alleged patent infringements and unfair trading. The latest action is unrelated.
Broadcom has accused Qualcomm of offering mobile phone makers who buy its 3G phone chips a better deal on its technology licenses than companies who buy Broadcom chips.
In its latest action, Broadcom is seeking undefined damages and an end to the alleged Qualcomm trading practices.
Qualcomm denies all Broadcom’s claims.
