What is a patent?

If you make a modification to an existing invention that is already covered by a patent, you cannot make your invention without the permission of the original patent owner. Many technical inventions and computing developments have relied upon cross-licensing agreements where a number of competitors allow each other to use their patents. If this didn't happen, the pace of new inventions, technology advancements and computer game developments would have happened much more slowly.
