When an invention is made, the inventor has three possible courses of action open to him: he can give the invention to the world by publishing it, keep the idea a secret, or【B1】______it. 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. Indeed, patent experts often advise anyone wishing to avoid the high cost of【B7】______a search through live patents that the one sure way of avoiding violation of any other inventor’s rights is to steal and use a dead patent. 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. [br] 【B8】
选项
答案
invalidates
解析
分析句子结构可知,此处缺一动词作谓语。换一种方式公布某种专利思想应该会使重新申请该专利的行为变得无效,故填invalidates。形容词valid意为“有效的”,加动词后缀-ate意为“使有效”,再加否定前缀in-变为反义词“使无效”。主语是publication,故谓语动词须用第三人称单数形式,注意词尾加s。
