Patents should be limited to a single scope of implementation! The real problem is that the USPTO will grant any patent to any huge corporation who lines their coffers (however "discretely" that may be), and allow for vague (excessively broad) patent applications to be approved.
They also convieniently ignore the abundance of prior art for the wealthiest of corporations (e.g. Apple and its bullshit patent on "Slide to Unlock", something that existed long before Apple stole it and called it their own).
The entire patent system serves to grant rights to the rich while excluding the poor.
Hell, even the patent on what we know as the Telephone was granted to Bell through an act of corruption at the USPTO! The design for the microphone used to transmit speech over copper wire was taken from the patent application of a genius Amish man and placed into Bell's "statement of intent" (because that's all he really had up to that point). Subsequently, the Amish genuis's patent was rejected in favour of what the USPTO gave to Bell.
These days its even more disgraceful with "design patents" like those granted to Apple, which serve only to propagate endless "it looks like ours" lawsuits (the cost of which invariably falls upon the consumer).
In fact, I seem to remember at one point someone filed a trademark on the name "Linux", and that you (+Linus Torvalds
) had to go to court to seize that trademark (is that right?)
Patent Trolls, Copyright Trolls, Trademark Trolls... all of them nothing but a bunch of parasites with not an ounce of worthwhile skill between them. Natural Selection should see their kind extinct, yet the artificial "society" our species has created rewards them while punishing those who posess genuine skill. If that's the result of "Humanity" then I'd rather be Inhuman!
