It's pretty clear you have no idea how patents work.
Patents are there to help protect IP which cost money to research and develop this protection was afforded mostly to help innovation and to protect the little guy, NOT to patent something as silly as a screen, speaker, and button combination.
Lastly patents do not have to be enforced and used in a manner to inhibit innovation or progress in a market place. In other words you shouldn't hog the patents for your own use, they should be licensed. This falls under unfair business practices for the most part specially for something as silly as a simple design concept, how Apple has been able to avoid getting charged for unfair business practices reeks of bureaucracy and very expensive legal departments. (This is evident in their lawyers quitting- lawyers DON'T quit unless unsavory practices are going on).
And to answer your question: No they honestly wouldn't for something as silly as a design. Most of the times they want royalties, not to impede sales.
We can all agree that the patent system is broken, but it really isn't apples fault for playing e game by the rules they were given. If the patent office would grow a pair and educate themselves maybe they wouldn't be approving patents for ridiculous ****. As it stands now they rubber stamp everything and let the courts figure it out.
