如何准备申请专利？获得专利要等多长时间

来听今天的讲解:

A: I'm going to apply for a patent but I'm not sure how to prepare the application. Would you please help me?

我想申请专利，但不知道如何准备，你能帮我吗？

B: Sure, glad to help. First you need submit a request, a description and a claim. The description is particularly important. If necessary, it should be supported by drawings.

当然，很高兴能帮忙。首先，你需要提交一份申请书，一份说明书和一份要求书。说明书尤其重要，必要的话，说明书应配有插图。

A: How long shall I have to wait for the approval?

获得专利我要等多长时间？

B: Well, examination takes time. The Patent Office will announce the result and notify the application within 18 months. Even then you still don't get the patent certificate.

哦，专利审查需要时间。专利局会在18个月内公布结果，公告专利。即使到那时，您也拿不到专利证书。

A: Why?

为什么？

B: The Patent Office needs 90 days to wait for any possible opposition. Only when everything is OK will the patent be registered.

专利局还需要90天时间看看是否有异议。只有一切都没有问题时，专利方可注册。

A: I see. But I have another question. I don't know the reason why the duration of protection is only 15 years?

我明白了，我还有一个问题。我不知道专利的保护期为什么只有15年？

B: This is only for one of the patent rights. For invention the duration of protection is even shorter, only for 5 years protection.

只有一种专利权保护期限是15年，发明专利保护期限是15年。至于实用新型和外观设计专利，保护期更短，只有5年。

A: Does every country specify the same duration of protection?

每个国家规定的保护期限时候都一致？

B: No, 15-year protection is the minimum protection any country will grant its patentees. In some countries, the patent right duration for invention is 20 years.

不是，各国都对专利人给予了最低15年的专利保护。在一些国家，发明专利的保护期是20年。

A: What are the criteria for granting patent rights?

授予专利的标准是什么？

B: They are similar to those in other countries: novelty, inventiveness and praticability.

标准和别国相似，都要求具备新颖性，创造性和实用性。
