We’d already reported on some Android-related problems this week, but concerns over a few nasty botnets will be a pale in comparison to how Google will feel today after news arrived that the tech giant Oracle is suing the search kingpins over its mobile OS.

Oracle CEO Larry Ellison has said he views the Java software as a key asset.

Oracle is alleging patent and copyright infringement in the development of the popular smartphone software.

The suit, filed yesterday in a California federal court, claims that Google “knowingly, directly and repeatedly infringed Oracle’s Java-related intellectual property” in developing Android.

Analysts say Google’s Android operating system uses portions of Java technology, but considering 200,000 phones with the OS are sold every day that could be make for some valuable “portions”. No wonder Oracle is getting involved.

Oracle spokeswoman Karen Tillman said in a statement. “This lawsuit seeks appropriate remedies.” Reuters point out that Oracle acquired Java through its $5.6 billion purchase of Sun Microsystems earlier this year. It’s been suggested that the suit against Google could signal that Oracle intends to be more aggressive in seeking licensees for Java which is used in a huge amount of Internet-based products.

Oracle Chief Executive Larry Ellison has said he views the Java software as a key asset, pointing to its use in a variety of electronic devices, from PCs to DVD players. “Sun’s corporate philosophy was obviously very different from Oracle’s in terms of enforcing the Java patents,” said Edward Reines, an IP litigator at Weil Gotshall who is involved in separate patent litigation against Oracle.

A Google spokesman said he could not comment on the lawsuit as the company had not had a chance to review it yet. Google of course will be well used to lawsuits at this stage, ever since they started to turn a profit and got ambitious they’ve had lawsuits fired at them on a seemingly weekly basis.
