答：商标通常是一个词、短语、符号或设计，或者是这些元素的组合，用来识别和区分一方的商品来源与他方的商品来源。服务标志和商标是一样的，只是它识别和区分的是服务而不是商品。

A: A trademark is generally a word, phrase, symbol, or design, or a combination thereof, that identifies and distinguishes the source of the goods of one party from those of others. A service mark is the same as a trademark, except that it identifies and distinguishes the source of a service rather than goods.
