Apple is expected to announce the new iPhone 5 at a press event this week in San Francisco. The release of the iPhone 5 should follow shortly after that, perhaps as early as September 21st. Without any consideration of the new hardware, there are already a few hurdles that Apple will need to overcome to allow the iPhone 5 and successive devices to reach their full potential.
Took a Samsung to the knee
The problems with Samsung are really two-fold. The most immediatly pressing are the rumors that Samsung will attempt to file an injunction to stop the sale of the iPhone 5 if that device supports LTE. With their pride still quite hurt from losing their latest patent battle in the US with Apple, they are looking for a way to regain a bit of pride. What better way than to mark it's territory and stop the iPhone 5 from being released by filing for an injunction based on their LTE patent portfolio.
On the flip side, Apple also has quite a few LTE related patents, recently purchased and the ones they already had. This should stop a judge from allowing the injunction, but you never really know with technology and judges. If this happens, expect a bit of a stock hit.
The long term problem with Samsung is their step-by-step duplication of Apple innovations. This will take Apple a long time to overcome in the courts, though recent court rulings have been both for and against Apple. It's a long road, and unfortunately will slow down both companies, and others in the industry. The only real winners in the fight will be the lawyers, as usual.
