6. Oracle and Google fight over Java

In 2010, Oracle filed a suit against Google claiming that the Android’s technology violated some copyrights and patents related to Java, which Oracle acquired along with Sun Microsystems.

Back when Google first announced plans to develop Android in 2007, it immediately raised the pressure of Java developers at Sun. Google's Java implementation is different than the one done by a Java standards group, which worried those tech industry veterans who remembered the problems that Microsoft caused for Java by following a similar path on Windows.

Oracle argued that Java is a mobile operating system competitor against Android, and that Google is using Java-derived technologies without a proper license.

It was predicted that Google will lose big-time and would pay heavily but that never happened.

The court decided that Google had infringed the Java patents, but they couldn’t decide whether it was fair use or not. Some among the jurors said Oracle was never close to win.
