"label patent trolls as leeches who extort money" - so there goes a good chunk of Apples income
Older readers, with a good memory, will likely recall all the 'adopting' (plagiarisation) Apple has done over the decades starting with both the corporate logo and name, followed by purloining Xerox designs, Japanese connectors, Creative of Singapore, etc.
Not all the problems are of Apples doing, many stem from the poor law that implements and governs the USPO activities. What stupidity awarded a patent for corners and curves? And pixel formations in icons/avatars?
In areas of fast development, where inventions have short Best Before times, they should patentable duration of five years.
I remember visiting George Barnes Boot Factory, Chesham, Buckinghamshire, and there were all these ancient machines for boot and shoe manufacturing. I asked why not more modern machinery and was told they had to rent the machines from an American company dating back to the 1800's.
They couldn't improve the designs as every which way was covered by patents.
No wonder the Chinese don't pay too much attention to patents. Can't really blame them.
