Alphabet CEO and Google co-founder Larry Page defended his company s development of the Android platform today during an ongoing legal battle with Oracle.

Oracle sued Google in 2010, claiming that Android developers copied sections of proprietary code from Java.

Google has maintained that the code in question was open source and free for its engineers to use, and that the implementation of the Java code in Android was transformative enough to be considered fair use.

He defended Google s decision to use the APIs without obtaining a license from Sun Microsystems, which was later acquired by Oracle, saying that copying and reimplementing the APIs in question was a standard industry practice.

Oracle attorneys presented Page with a Google slide deck that said the Android ecosystem was generating $43 billion in revenue each year.

I don t know how much that has to do with Google, Page testified, adding that carriers like Verizon made a lot of money, but that doesn t do Google any good.
