A granted patent is the result of a【B2】______struck between an inventor and the state, by which the inventor gets a limited period of【B3】______and publishes full details of his invention to the public after that period【B4】______
    Only in the most【B5】______circumstances is the life span of a patent extended to alter this normal process of events. A patent remains【B6】______ public after it has terminated.

Likewise, because publication of an idea in any other form permanently【B8】______further patents on that idea, it is traditionally safe to take ideas from other areas of print.【B9】______. Anyone closely-involved in patents and inventions soon learns that most new ideas are, in fact, as old as the hills.【B10】______that makes news and money. The basic patent for the theory of magnetic recording dates back to 1886.【B11】______. Even the Volkswagen rear engine car was anticipated by a 1904 patent for a cart with the horse at the rear.
