What is a patent
Patent is the grant of a property right to the inventor that gives him a temporary monopoly on the manufacturing and sale of the object of the invention.
In this way inventors are granted the right to exclude others from making, using, selling exporting and importing the objects that fall within the patent protection.
The term of patents for industrial invention is twenty years.
Patents for utility model are valid for ten years.
In both cases, pantents are valid only as long as the required government fees are paid.
