By Dan Levine SAN FRANCISCO (Reuters) - Oracle Corp filed a multibillion-dollar copyright lawsuit against Google because Oracle failed in its own attempts to enter the smartphone market, a Google attorney said in closing arguments on Monday. In a retrial in federal court in San Francisco, Oracle Corp has claimed Google's Android smartphone operating system violated its copyright on parts of Java, a development platform. Alphabet Inc's Google unit said it should be able to use Java without paying a fee under the fair-use provision of copyright law.
