UNIX 系统被认为是目前应用极为普遍,最强有力的操作系统之一,尤其对于微型机和小型机来说是如此。截至1982年7月1日止,美国电话电报公司(AT&T)已经出售了1,654个有关 UNIX 的专利。此外,大约还有8,000个装置实际上安装了 UNIX 系统。值得一提的是,在此之前,AT&T 受美国法律条款限制,从未公开在市场上出售这个产品,并且不作任何支持也不给任何担保,因此,达到这么个数量是令人吃惊的。由于版本不同,其专利费从20,000到43,000美元不等。据美国 UNIX 信息服务的市场调查员 Gnostic Concepts 估计,到1985年,基于 UNIX 的计算机系统的年
UNIX systems are considered to be one of the most popular and powerful operating systems in use today, especially for microcomputers and minicomputers. As of July 1, 1982, AT&T had sold 1,654 patents on UNIX. In addition, about 8,000 devices actually have UNIX systems installed. It is worth mentioning that prior to this, AT&T was restricted by U.S. law and had never publicly sold the product on the market, and did not provide any support nor guarantees. Therefore, it was surprising to achieve such a quantity. Due to different versions, their royalties range from 20,000 to 43,000 U.S. dollars. According to estimates of Gnostic Concepts, a market researcher for U.S. UNIX information services, by 1985, the number of UNIX-based computer systems
