A Tokyo court has rejected Samsung’s allegations that Apple hijacked the South Korean company’s data transmission technology for use in its iPhones.

The judge denied Samsung’s request for a sales ban on Apple devices that make use of the data transmission technology.

The ruling is a blow for Samsung in its ongoing global patent war with arch-rival Apple.

“We are disappointed by today’s court decision,” Samsung said in a statement to media outlets. “Following a thorough review of the ruling, we will take the measures necessary to protect our intellectual property rights.”

Samsung filed the patent lawsuit in April of 2011, claiming the patent violations were connected to three specific technologies: HSPA telecommunications to optimize transmission and reduce the use of power during data transmission, WCDMA telecommunications technology to reduce date transmission errors and technology for linking a cellphone to a computer to enable the computer to use the handset’s wireless data connection.

Samsung filed the lawsuit in response to Apple filing suit the previous week. Apple’s suit asked the court to enact a sales ban of the Galaxy S and S2 Smartphones and the Galaxy Tab 7 tablet.

The next big case between the two companies is set for March 2014 in the U.S.  Apple is alleging Samsung has violated patents that include the rights to the search technology integrated in the iPhone Siri voice feature.

U.S. District Judge Lucy Koh has insisted both sides cut down on the number of patent violation claims before the case goes to court.

Koh presided over last summer’s trial, during which a jury found Samsung guilty of violating six of Apple’s patents. The jury awarded Apple $1.05 billion — the largest patent verdict in history.

Despite the jury’s ruling, however, Koh denied Apple’s request last fall for a sales ban against 26 of Samsung handsets.

Apple appealed for more than half a billion dollars in additional damages against Samsung for patent violation after losing its injunction bid.
