For all you people calling this company a "patent troll"...or whatever, If you designed a technology, patented it and then someone else made millions of dollars off of it.. you would be in court too. it is apparent that MS, Sony, Nintendo.. and most likely many more, have infringed upon this patent.
There are three main categories for patents:
Utility patents may be granted to anyone who invents or discovers any new and useful process, machine, article of manufacture, or composition of matter, or any new and useful improvement thereof;
Design patents may be granted to anyone who invents a new, original, and ornamental design for an article of manufacture; and
Plant patents may be granted to anyone who invents or discovers and asexually reproduces any distinct and new variety of plant.
When you submit a patent, there is a board of officials that examine your submission. If there is no current patent on file for your idea/design, then they will grant you a patent. You must maintain your patent by paying fees. They will grant your a 10 or 20 year patent, which can be renewed at the end of its term.
its plain, its simple.
So before some of you people spout off about "patent trolls".. do yourself a favor and read the patent procedures and laws before you comment. Because until you do, the only "Troll" here is you.
