When an invention is made, the inventor has three possible【C1】______of action open to him: he can give the invention to the world by publishing it, keep the idea【C2】______, or patent it.

Because a patent remains permanently【C10】______after it has terminated, the shelves of the library attached to the【C11】______office contain details of literally millions of ideas that are free for anyone to use and, if【C12】______than half a century, sometimes even re-patent. Indeed, patent experts often advise anyone【C13】______to avoid the high cost of conducting a search through【C14】______patents that the one sure way of violation of rely other inventor’s right is to plagiarize a dead patent. Likewise, because publication of an idea in any other form【C15】______invalidates further patents on that idea, it is traditionally【C16】______to take ideas from other areas of print.

The basic patent for the theory for magnetic recording dates back to 1886. Many of the original ideas behind television originate【C20】______the late 19th and early 20th century.
