美国专利实务中经常提到的 teach away 具体什么意思？谢谢

反向教导，就是专利明示或者暗示的指出不能如何如何做。而你的专利恰恰是如何如何做的，即逆prior art而行。

因而具有创造性。

我也想补充一下：在美国实践中，teach away 的主词比较适用于先有技术，而不适用于本身的发明。比如说：The prior art teaches away from a plurality of servers that is recited in claim 2.  

而权利项的动词是 recite，比方说：Claim "recites" a plurality of servers having asynchronous updating schedule in response of user interactions.

用于说明书的动词是：disclose，比方说：The specification/invention discloses that server updates that reflect user interactions are more efficient than static or preset time schedules...

而对于先有技术的动词多半用 teach，比方说：Prior art "teaches" that server updates based user interactions are difficult.  In fact, the prior art teaches away from server updates based on user interaction by setting a predetermine time schedule of the update.

要是中英对照进行解释就更好了

嗯，觉得你说的很对啊！
