Android has been going through many patent issues right from the day, or even before it got introduced to general public! Lets have look at some of them:
- On August 12, 2010: Oracle sued Google over claimed infringement of copyrights and patents related to the Java programming language.
Details: Oracle originally sought damages up to $6.1 billion, but this valuation was rejected by a federal judge who asked Oracle to revise the estimate. In response, Google submitted multiple lines of defense, counterclaiming that Android did not infringe on Oracle’s patents or copyright, that Oracle’s patents were invalid, and several other defenses. They said that Android is based on Apache Harmony, a clean room implementation of the Java class libraries, and an independently developed virtual machine called Dalvik.
In May 2012 the jury in this case found that Google did not infringe on Oracle’s patents, and the trial judge ruled that the structure of the Java APIs used by Google was not copyrightable.
