Apple's arguments for a preliminary injunction to block sales of certain Samsung Galaxy products in the U.S. failed, delivering a blow to the iPad maker's position in the ongoing global patent dispute.

In a late Friday ruling it was announced that Apple's request for an early U.S. ban on certain Samsung mobile devices was shot down by District Judge Lucy Koh in San Jose, reports Reuters.

Koh denied Apple's bid to stop the sale of the Droid Charge, Galaxy S 4G, Infuse 4G and Galaxy Tab 10.1 in the U.S.

"It is not clear that an injunction on Samsung's accused devices would prevent Apple from being irreparably harmed," Koh wrote.

The ruling is not the end of the lawsuit, and Koh noted that Apple was likely to prove that Samsung infringed on at least one tablet patent. She goes on to say, however, that the Cupertino, Calif. tech giant still needs to prove the patent's validity, something it had not shown thus far.

Kristin Huguet, spokeswoman for Apple, reiterated previous statements saying that Samsung's "blatant copying is wrong." Samsung did not immediately issue a statement.

The news is the latest development in the ongoing legal war between the rival handset and tablet makers, which now spans across 10 countries and includes over 20 separate cases. Apple initially sued Samsung in April, claiming that the Galaxy line of mobile products copied the look and feel of the iPhone and the iPad.

Most recently, a preliminary injunction against Samsung's Galaxy Tab 10.1 was overturned in Australia, though Apple won a week-long extension on the ban to file an appeal. The iPhone maker is waiting to see if its application will be granted by the High Court.
