I thought you might like to see the Lagos Analysis Corp.'s keyboard "patent" allegedly infringed by OLPC. It turns out it's not a patent in the usual sense. It's a design registration. Why does that matter? Because what is registered is the way it *looks*, not the way it *works*. Obviously, that has implications for searching for prior art. I don't know anything about Nigerian patent law, but here's how the USPTO FAQ explains the difference between a utility patent and a design patent in the US system:
What is the difference between a utility patent and a design patent?
A utility patent may be granted to anyone who invents or discovers any new and useful process, machine, article of manufacture, compositions of matter, or any new useful improvement thereof. A design patent may be granted to anyone who invents a new, original, and ornamental design for an article of manufacture.
So, if looks are what count, would you like to see how it looks? I have the certificate of registration from Nigeria.
