The Apple/Samsung patent war keeps grinding on. In the latest battle, Samsung's request that it be allowed to continue to ship some older Android devices to the US market was rejected by the Obama administration.

As reported by Bloomberg, US Trade Representative Michael Froman said in a statement, “After carefully weighing policy considerations, including the impact on consumers and competition, advice from agencies, and information from interested parties, I have decided to allow the import ban to proceed."

The banned devices are those that have been found to violate two of Apple's patents . These are:

US Patent No. 7,479,949, aka the ’949 patent; affects claims 1, 4-6, 10, and 17-20): Concerns touch commands on touch-screen devices.





US Patent No. 7,912,501, aka the ’501 patent; affects claims 1-4 and 8): Concerns input and output detection for microphone and headphone jacks.

It's not clear which Samsung smartphones and tablets will be banned. Newer Samsung devices, such as the Galaxy Note 3 or Note 10.1 , will not be banned.

Normally, the executive branch of government doesn't veto decisions by the US International Trade Commission (ITC). However, in a rare move, the government had vetoed the ITC's ban of some older iPhone 4, iPhone 3GS, iPad 3G, and iPad 2 3G devices following Apple's loss to Samsung in another patent infringement suit.
