A key milestone in Qualcomm's punishing legal war with Apple kicked off last week with testimony in the San Diego's company's bid to block certain iPhones from being imported into the US. 

Opening arguments started Friday in the first of two patent infringement cases that Qualcomm has brought against Apple at the US International Trade Commission. Testimony is expected to continue until June 26.
