举例来说，微软的某些服务器软件的接口是不公开的，只有微软自己的前端产品才知道，并通过这些接口与后端服务器相连。这样的“私有协议”的效果就是通过微软在前端的绝对优势，逐渐把用户也绑到微软的后端产品上。这种“私有”信息到底受什么保护，仍旧是在各国法庭上争论不休的题目。
For example, the interface of some MS server software doesn't disclose to the public, only the front end products of MS can, and through the interface connect to the back end servers. The result of these "private protocols" put front end products of MS a absolute advantage, it will gradually cause the users tie up with MS back end products. What kind of protection about the "private" information, still an arguable topic in the courts of many countries.
