The three cases filed Thursday were all filed in U.S. District Court for the Southern District of California in San Diego. One of the cases is a companion civil lawsuit to a new complaint also filed Thursday with the ITC that seeks the same remedy of banning iPhones with Intel chips. The other two cases are civil patent infringement lawsuits.
The dispute between Apple and Qualcomm over patents is part of a wide-ranging legal war between the two companies.
In a related suit, Qualcomm sued the contract manufacturers that make Apple’s phones, but Apple joined in to defend them.
Qualcomm in November sued Apple over an alleged breach of a software agreement between the two companies. Apple emailed Qualcomm to request “highly confidential” information about how its chips work on an unidentified wireless carrier’s network, Qualcomm alleged, but Apple had copied an Intel engineer in the email for information.
