Not surprisingly, Samsung plans today to file preliminary injunction motions against Apple over its new iPhone 4S. The South Korean-based company is hoping to convince courts in Paris and Milan, Italy to stop the sale of Apple’s next-generation handset before they begin, according to CNN.

Samsung and Apple have for months been at odds with both accusing the other of stealing patents. Today’s likely filing deals with the Wideband Code Division Multiple Access (WCDMA) standards for 3G mobile handsets.

According to a Samsung spokesman:

“Apple has continued to flagrantly violate our intellectual property rights and free ride on our technology, and we will steadfastly protect our intellectual property,” Samsung said in a statement.

Announced by Apple yesterday, the iPhone 4S debuts on Friday, October 14 in seven countries, including France. Meanwhile, the handset is expected to become available in Italy towards the end of October.
