The U.S. International Trade Commission will review a potentially key decision in the patent fight between Samsung Electronics and Apple over smartphones and tablets.

ITC will review in its entirety the final initial determination issued by the administrative law judge (ALJ) on October 24,2012. The judge ruled in October that Samsung, the world's top maker of smartphones, infringed four Apple patents but did not violate two others.

The commission said on Wednesday it would review the judge's decision, and asked the agency judge to take a second look at parts of two patents where he had found that Samsung infringed.

The review means that the final decision, originally scheduled for March 27, will be pushed back.

Apple had filed a complaint in mid-2011, accusing Samsung of infringing its patents in making its Captivate, Transform and Fascinate smartphones, as well as the Galaxy Tablet.

The ITC is also reviewing an initial determination that cleared Apple of infringing on Samsung?s wireless technology patents, after the Korean company appealed.
