Seeking to capitalize on a $1 billion legal victory over its rival Samsung, Apple is launching yet another lawsuit alleging further infringement.
Apple has asked a federal court in a separate case to find that four additional Samsung products, including the Galaxy S III and the Galaxy Note, infringe Apple's patents.
If the court finds those devices are infringing Apple's patents
and irreparably harming the company, it could temporarily halt
sales in the US market even before the trial begins, the Associated
In February, Apple alleged that at least 17 Samsung products infringe its patents.
In a court filing made in San Jose federal court, Apple added four more products to the list of allegedly infringing products that have been released beginning in August 2011 and continuing through this month.
In documents filed on Friday, Apple said 21 Samsung smartphones, media players and tablets released after August 2011 were "copycat products", AP said.
"Rather than innovate and develop its own technology and a unique Samsung style for its smartphone and tablet computer products, Samsung has chosen to copy Apple's technology, user interface, and innovative style," Apple said in one document.
One patent is related to the way the device retrieves information in a computer system and another is about gestures on a touchscreen display to unlock a device, AP reported.
Samsung has hit back at Apple's attempt to halt sales of the S III.
"Apple continues to resort to litigation over market competition in an effort to limit consumer choice," Samsung said in a statement to The Telegraph. "We will continue to take the necessary legal measures to ensure the availability of our innovative products in the United States."
Apple won a major victory over Samsung last week in a separate case when a jury found that the South Korean company had copied critical features of the hugely popular iPhone and iPad and awarded the US company $1.05 billion in damages.
Samsung representatives did not immediately respond to requests for comment.
