Category of Chinese Patent
Chinese patent includes the invention, utility model and design.
Invention: any new technical solution relating to a product, a process or the improvement thereof.
Utility Model: any new technical solution relating to the shape, the structure, or their combination, of a product, which is fit for practical use.

Guidelines for Chinese Patent Application
1. Do necessary search: before filing an application for a patent, the applicant shall do necessary search to ensure the novelty and inventiveness of the patent application.
2. Determine the category of the patent application: the applicant shall determine the category of the patent application according to the subject matter which is in need of protection.
3. Entrust an agent: instruct an agency to prosecute the patent application by the agency contract, the email, the fax and etc.

The said contents shall use technical terms and exclude jargons or common sayings.
Guidelines for Foreign Patent Application
In accordance with the provisions of Article 20 of the Patent Law of the PRC, Where any Chinese entity or individual intends to file an application in a foreign country for a patent for invention-creation made in China, it or he shall file first an application for patent with the Patent Office under the State Council and appoint a patent agency (or foreign-related agency) designated by the government to act as its or his agent.
The applicant can enjoy right of priority based on his first Chinese patent application, if he files in a foreign country an application for a patent within the prescribed priority period.  After the prescribed priority period, the applicant may also file in a foreign country an application for a patent if the first Chinese patent application has not been disclosed yet but no longer enjoys right of priority.  The prescribed priority period for the invention or the utility model is 12 months, the design 6 months.
1. Channels of application
A foreign patent application can be filed through the Paris Convention or PCT channel.
Channel of Paris Convention
In 1883, the Paris Convention for the Protection of Industrial Property was concluded in Paris of France.  China joined the Paris Convention on March 19, 1985.  There are over 150 state members up to now.  Major contents of the Paris Convention are (1) principle of national treatment: nationals of any state member of the Paris Convention shall, as regards the protection of industrial property, enjoy in all the other state members of the Paris Convention the rights that may grant to nationals; (2) principle of priority: a specific applicant who has filed an application for an industrial property in one of the state members may apply for protection in the other state members within the prescribed period (6 months or 12 months), and the subsequent application shall be deemed to have been filed at the same date as the first filed application, i.e., the application enjoys a right of priority, compared with the same invention-creation of other person (from the first application to the subsequent application); (3) principle of independent patent: patents in one country shall be independent of patents obtained for the same invention in other countries, according to which, the applicant who intends to obtain a patent in one country must apply with the patent office of the country for approval thereof.
Advantages of the Paris Convention channel:
(1) Quick and convenient: a patent may be granted in some countries quickly, and can be further used for the purposes of license, assignment and so on.
(2) Grant of a patent in some countries can be used as powerful grounds to persuade examiners of other countries to make a decision of granting a patent, for example, the German patent, EU patent and etc can be used for such purpose.
(3) If the application is only filed in one to two counties, then the cost is lower.
 PCT Channel
PCT was concluded on June 19, 1970 and came into force on January 24, 1978 for the purpose of simplifying formalities and procedures of international patent application, facilitating transmission and utilization of technical information, strengthening legal protection of invention-creation, promoting scientific, technical and economic development of states parties and adapting to globalization trend of patent systems.  China formally filed an application with the WIPO on September 13, 1993 which became effective automatically three months later and joined the treaty as the receiving office, the international searching and preliminary examining authority.  Up to January 2003, the state members of the treaty included 88 countries and 4 regions.  This is a channel for application (no grant of patent).  The international application filed according to PCT not only can seek protection of the invention but also can enjoy right of priority in any of the states members.  The international application has the same legal effect as the national and regional patent application.  An international application can equal to applications in all countries and regions in which protection is in need.  PCT essentially unifies the international patent application filing, but it has not yet unified the grant of patent and the issue of international patent.
The Chinese citizens or enterprises may file international patent applications with the State Intellectual Property Office or the International Bureau.
The applicant may file an international patent application directly.  He may also file a Chinese patent application first and an international patent application later, with right of priority based on the first one.  The prescribed period of international phase in most countries is 30 months.  The applicant may enter the national phase upon the expiry of that period or in advance.
Advantages of PCT channel:
(1) Unified application: the international application may be filed in one place (China), one language, one style and one copy and with the payment made in one currency, which renders in other state members or regional patent organizations the same effect as the national or regional patent.
(2) Obtain right of priority most quickly: the filing of international patent application may be done nearby (the Chinese Patent Office), and moreover, the PCT application may be filed in the language of one's own country.  Therefore the applicant may file the application at the last moment of the priority period and enjoy right of priority by filing the international application easily.
(3) The applicant may obtain a copy of the international search report around 9 months after the filing date or 16 months after the priority date; the applicant may also obtain a copy of preliminary examination report within 28 months from the filing date or the priority date (if the applicant files a demand for international preliminary examination within the prescribed period).  The applicant may determine, based on the prior art in the foresaid two reports, whether he should enter the national phase.  The PCT application may defer the entry into national phase for 8 to 18 months, which is definitely valuable to the applicant who has not been prepared.
Disadvantages of PCT channel:
The filing of international application is divided into international and national phases.  The international phase mainly deals with receiving, publication, searching and preliminary examination matters, but the searching and preliminary examination are just to provide reference for examination in the national phase and for the applicant and do not enjoy effect of course.  The national phase mainly deals with grant of patent in the country or region.  Therefore the formalities of international application are relatively complicated and the charge of fees is divided into two phases, which may add burdens to the applicant with specific economic interest.  Moreover, the international application can not be chosen for protection of a patent of design.
