[Green Circle Talks About Cross-Border] Is a Domestic Patent Application Valid Abroad?

Is a domestic patent application valid abroad?

Patents are an important way to protect inventions, and for many enterprises and individuals, the validity of a patent abroad is often considered when applying for a patent. So, can patents applied for in China be protected abroad? This is a question worth exploring in depth.

First of all, it is important to understand that the scope of protection of a patent is usually limited to the country or region in which it is located. This means that if you apply for a patent domestically, you will usually only be able to obtain protection in the country or region in which you are located, and will not be able to extend it directly to other countries. Therefore, if you wish to obtain patent protection abroad, you will usually need to file a separate patent application in the appropriate country or territory.

However, there are some special circumstances where your domestic patent application may be protected in certain countries or regions. This is usually achieved through the international patent application process of the Patent Cooperation Organization (PCT). Through the PCT program, you can indirectly achieve foreign patent protection by filing an international patent application and choosing to have your patent examined in multiple countries or regions that have signed the corresponding agreements.

In addition to the PCT program, there are also reciprocal patent agreements between some countries, whereby two countries grant specific treatment to citizens of the other country in specific areas. In this case, a patent filed in one country may be protected in another country that has signed a reciprocal agreement.

Generally speaking, whether a domestic patent application is valid in a foreign country depends on the specific country or region, as well as the corresponding international patent application procedures or bilateral agreements. When applying for a patent, if you intend to obtain corresponding protection in foreign countries, it is recommended that you understand the local patent protection policy in time and adopt appropriate application methods according to the specific circumstances to ensure that your patent is effectively protected in foreign countries.
