A US Patent is a right granted by the US government, which normally lasts 17 years from the official date of granting of the patent.
美国专利是经美国政府批准的权利，有效期从正式被授权日起，通常是17年。

There are two kinds of rights given to the patent owner.
专利所有者有两种权利。

One such right allows the patent owner to stop others from making, using, or selling the claimed invention. This also allows the patent owner to stop imports of the claimed invention into the US by others.
一项权利是保护专利所有者的发明不被制造、使用或销售。这也使专利所有者有权阻止他人进口该项发明进入美国。

The other main right given to the patent owner is as a kind of shield against most types of lawsuits by competitors. This prevents competitors from copying the invention and trying to patent it themselves. And, the patent is proof of the date of filing. There are some exceptions to this, mainly related to a prior patent holder claiming earlier and broader patent rights.
另一项主要的权利是专利权可以作为专利所有者对抗竞争对手法律诉讼的保护伞。该权利防止竞争对手抄袭该发明，企图取得专利。另外，专利也是提交申请日的证明。当然也有一些例外，主要涉及专利前持有者要求早先的或更广泛的专利权。
