5. Oracle Lawsuit Charges Google With Infringing Java Patents Signaling it will aggressively defend its newly acquired Java technology, Oracle sued Google in August claiming that Google's Android mobile operating system violated Java patents and copyrights. The lawsuit pits Oracle, one of Silicon Valley's long-time technology powerhouses, against Google, which has become one of the IT industry's major players in the last decade. Google responded by denying Oracle's charges and in a court filing sought to have the patents declared invalid. Oracle acquired Java and its related patents and copyrights when it bought Sun Microsystems for $7.3 billion. In the suit Oracle called Java "one of the most important technologies Oracle acquired with Sun," noting that it has attracted more than 6.5 million developers.
