There are millions of products/patents that have been around for hundreds of years
Patents do not last hundreds of years, Dolby. The exact term varies from country to country (unlike copyright, you have to apply for a separate patent in every country you want to operate in. It gets expensive and time-consuming, which is why Apple probably does not own any patents in Burundi). 20 years is typical:
A patent is not a right to practice or use the invention. Rather, a patent provides the right to exclude others from making, using, selling, offering for sale, or importing the patented invention for the term of the patent, which is usually 20 years from the filing date subject to the payment of maintenance fees. A patent is, in effect, a limited property right that the government offers to inventors in exchange for their agreement to share the details of their inventions with the public. Like any other property right, it may be sold, licensed, mortgaged, assigned or transferred, given away, or simply abandoned.
Getting your competition banned from the market is
EXACTLY what the patent system was set up to do. You can argue that it is a bad system. You can argue that it no longer functions the way it was originally intended to do. But how can you justify criticizing Apple for utilizing the system in which they find themselves, using it exactly for the purpose it was set up for, and ignoring the fact that everybody else is suing them at the same time.
So, in the Gospel According to Dolby, Apple enforcing its rights is bad. Samsung, HTC, Microsoft etc etc enforcing their rights is good, or at least not to be mentioned in polite company.
IMO Apple is weary ... Steve already exploded that Android copied him (and eating into his sales in the phone market) and I think they realize this will translate into the tablet market too.
Apple has no divinely-appointed right to 100% of any market. They've done well the last ten years, but they live and die with the next product announcement. Just like Samsung, HTC, Microsoft etc etc. I suspect they are smart enough to realize that.
Soon enough we will see something new from Apple, most likely something that exists already, but which nobody now takes seriously. The pundits will tell us that it will never sell. And it will explode onto the market and Samsung, HTC, Microsoft etc etc will be desperately trying to catch up once again. This is how Apple operates. Tablets and phones are already in a holding pattern and they are working on the next opportunity to blow our minds.
