Apple has renewed its legal tussles against Samsung with a court filing last week that sought to prevent the South Korean from introducing its new Galaxy products to the American market.

Bloomberg reported that Apple lodged the new lawsuit before a San Jose, California Federal Court on Feb. 8, targeting this time the Samsung Galaxy Nexus, one of the first Android handset powered by Google's latest mobile platform - the Ice Cream Sandwich.

Apple claimed that Samsung has violated four additional patents, including the technology behind Siri, the virtual assistant that the company deployed with the bestselling iPhone 4S when it was released in October last year.

That specific patent, which Apple said was again copied by Samsung to be used on the Galaxy Nexus, allows users to search for multiples sources with the use of only a single entry.

"Samsung has systematically copied Apple's innovative technology and products, features, and designs, and has deluged markets with infringing devices in an effort to usurp market share from Apple," court records showed Apple as saying its suit.

"Apple is filing this suit to put an end to Samsung's continued infringement," Bloomberg reported the U.S. tech titan as saying on its complaint.

Analysts noted that Apple's claims against Samsung this time centred on the technical patents, which detracted from the company's earlier suits against Samsung products that the California said were made to feel and function like the iPad.

Apple had asked the same court last year to ban the sale of Samsung's Galaxy Tab 10.1 in the United States but was rebuffed before the end of the year, a ruling that was replicated by an Australian court at almost the same time.

This time though, Apple's case is backed by its triumph against Taiwanese tech firm HTC in December last year when the International Trade Commission ordered the Asian mobile phone maker to stop selling handsets that carry technologies exclusively owned by the American company.

The legal battles between Apple and Samsung, which were being waged in a number of courts across the globe, represent an extension of the two firm's competition for dominance of the international smartphone market.

As of the end of 2011, Apple remains the number one brand but Samsung is not too far behind, with their sales figures separated only by a few hundred thousands of total unit sales.

The showdown, analysts said, also showcased the searing rivalry between Apple and Google, currently two of the most dominating names both in tech and business world.

According to Dow Jones Newswires, Samsung has acknowledged Apple's new filings and insisted that it will "defend against Apple's claims to ensure our continued innovation and growth."
