Oracle has filed a lawsuit against Google, charging that its Android phone software infringes on Oracle patents and copyrights related to Java, Oracle said on Thursday.
"In developing Android, Google knowingly, directly and repeatedly infringed Oracle's Java-related intellectual property. This lawsuit seeks appropriate remedies for their infringement," Oracle spokeswoman Karen Tillman said in a statement.
The suit was filed Thursday in the U.S. District Court in San Francisco and seeks a jury trial.
Google did not immediately respond to a request for comment.
Oracle acquired Sun Microsystems' Java technology when it bought the company earlier this year.
