iPhone 4S’s Antenna System Infringing On Samsung Patents?

Danish professor Gert Frølund Pedersen who originally predicted the controversy surrounding the iPhone 4’s antenna issues has come forward once again.

9 to 5 Mac reports that the expert now says that Apple may be infringing on Samsung’s patents.

As we’ve reported before, iPhone 4S includes significant upgrades to its antenna system. The ability to switch between two antennas dynamically for both sending and receiving means that the dead grip issues observed with iPhone 4’s antenna system should be practically non-existent for users.

Professor Pedersen states, simply:

The idea is good enough, but the question is whether they are allowed to use it.

He and others at the Danish university of Aalborg speculate that Apple will run into some legal problems. Samsung has two patents (one | two) that cover technology on intelligently switching between different antennas.

One particular method of changing antennas in these patents does so by checking if the device is in portrait or landscape mode. Pedersen thinks that this feature may be included in the new iPhone 4S’s antenna technology. Since we don’t have much concrete information on the device as yet, the professor goes on to say:

I can not say that they are directly breaking the patent, but there are not many ways they can choose the right antenna, without coming to break many patents.

This is hot on the heels of Samsung’s recent move to ban the iPhone 4S in Italy and France and it looks like Samsung has not yet used these patents in its litigation with Apple.

So this could potentially add more fuel to the fire in the patent war between Apple and Samsung.
