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.
