No one may be anticipating Apple's iPhone 5 more than Samsung Electronics, which reportedly wants to block the sale of the smartphone on its own turf, South Korea.

Unnamed sources cited by tech news site Digital Trends says Samsung will seek revenge for Apple's successful global blockades on its new line of Galaxy smartphones and tablet computers.

Claiming that the new Samsung devices are mere clones of its million-selling iPhones and iPads, Apple filed a copyright infringement suit that has so far resulted to court orders prohibiting the sale of Galaxy 7.7, Galaxy 10.1 and other related gadgets to major markets in the world.

Samsung recently filed appeals in Australian and German courts to lift the Galaxy ban in those countries.

"Just after the arrival of the iPhone 5 in South Korea, Samsung plans to take Apple to court here for its violation of Samsung's wireless technology related patents," Digital Trends quoted a company official saying Tuesday.

The same executive expressed confidence that Samsung will get Apple's attention as he stressed "it would be impossible for it to sell its branded products without using our patents."

Despite their legal struggle, Apple and Samsung are major trading partners. According to industry observers, the Cupertino, Calif.-based company is set to spend some $7 billion for device parts that the South Korean firm will deliver this year.

Most of the Samsung supplies, reports said, will be installed on the bestselling iPhone 4 and it is not yet clear if the company will continue its partnership with Apple for components needed to assemble the upcoming iPhone 5 and iPad 3.

Many experts still doubt Samsung would be willing to collide head-on with Apple, which represents its biggest account so far and whose gadget products generate considerable revenues for a number of South Korean telecommunication firms.
