How long will it take after accepting the patent application?

In the process of examination and approval, the invention patent needs to go through:

Generally speaking, it takes about 18 months from acceptance to publication, and about 1.5 to 2 years from actual trial to authorization.

Applicants who want to speed up the examination and approval cycle can apply for early disclosure, which can speed up the patent authorization cycle.

For utility model patents and design patents, the examination and approval only need to go through three stages: acceptance, preliminary examination and authorization, which is much shorter than the authorization period of invention patents, generally within 6 months.

1. How long does it take to apply for a patent number?

Patent applications in China are divided into three categories: invention patents, utility model patents and design patents. According to different types of patent applications, the time for issuing certificates to complete applications and obtaining patent numbers is also different.

1. It takes about two years to get a patent certificate for an invention patent.

Generally, it takes about three months to issue the notice of preliminary examination, six months to enter the preliminary announcement, one and a half years to issue the notice of review opinions, and two years to get the patent certificate.

Because the technical fields of invention patents are wider, the review period of different technical fields is quite different, and some technical fields may take two to three years or even longer.

2. The patent for utility model received the Notice of Patent Acceptance from the Patent Office within a week or so, with the patent application number. It takes about six to twelve months to receive the patent certificate.

3, the design patent is also about half a year to get a patent certificate.

Receive the acceptance notice from the Patent Office within five working days, and issue the patent application number in about one week, that is, the patent number of the patent certificate in the future.

After receiving the patent authorization notice about five months from the date of application, pay the certificate fee according to the regulations, and issue the patent certificate about two months.

Second, what is an invention patent?

The invention mentioned in China's patent law refers to a new technical scheme proposed for a product, method or its improvement.

Characterized in that:

Firstly, the invention is a new technical scheme. It is a technical scheme to solve various problems in production, scientific research and experiment by using natural laws, and generally consists of several technical features.

Secondly, according to the nature, there are two basic types of invention claims, product claims and method claims.

Product claims include things (products and equipment) produced by human technology, and method claims include activities with time process elements, which are divided into methods and uses.

An invention protected by the patent law can also be an improvement of an existing product or method.

An invention granted a patent right shall be novel, creative and practical.

Novelty means that the invention does not belong to the prior art; Before the filing date, no unit or individual filed an application with the Patent Office for the same invention or utility model, and it was recorded in the patent application documents published or announced after the filing date (including the filing date).

Creativity means that the invention has outstanding substantive characteristics and remarkable progress compared with the technology known to the public at home and abroad before the application date. Practicality means that the invention can be manufactured or used and can produce positive effects.

Third, what is specialization? Proof of profit

A patent certificate is a document issued by the patent office to prove the patent right.

After the patent application is examined and approved, the Patent Office shall make a decision to grant the patent right and issue a patent certificate.

A patent certificate mainly records the name and patent number of the invention-creation, the names of the inventor and designer, the name and title of the patentee, the scope of rights protection, and the time when the patent was granted.
