[Direct answer]In the Beijing area, if an applicant files a patent application for the same invention or utility model with the Patent Administration Department under the State Council within twelve months from the date of first filing the patent application in China, they may claim domestic priority and enjoy the benefits of the filing date of the first application. According to Article 29 of the Patent Law of the People's Republic of China (effective June 1, 2021), claiming domestic priority requires submitting a written declaration and a copy of the first application within the twelve-month period; the first application will be deemed withdrawn after the priority claim is requested. It is recommended that enterprises plan as early as possible after the first application to avoid exceeding the deadline.

1. Problem background and typical scenarios

Domestic priority rights are commonly encountered in situations where an applicant first submits an application for a utility model or invention patent, and then files another application on the same subject within twelve months, claiming the priority date of the first application. Typical scenarios include: enterprises first occupying a position quickly with a utility model, then submitting an invention application on the same technology and claiming domestic priority rights, in order to balance the speed of authorization and the depth of protection; or the first application is flawed, so the applicant reapplies on the same subject with domestic priority rights and considers the original application withdrawn. Its value lies in "time travel" - the later application can enjoy the priority date of the earlier application.

II. Key points of contention

There are three main points of contention. Firstly, the determination of the same subject matter: whether the subsequent application and the first application concern the same subject matter, which determines whether the priority right can be established. Secondly, the twelve-month time limit: starting from the date of the first application, if the time limit is exceeded, the domestic priority right will be lost. Thirdly, the processing of the first application: after claiming the domestic priority right, the first application will be deemed withdrawn, and it is necessary to weigh whether it is worth doing so.

III. Professional analysis by Hengluo Law Firm

Based on practical observations of enterprise patent application management, domestic priority right is a cost-effective deployment tool, but its procedural consequences are often overlooked. According to Articles 29 and 30 of the Patent Law (effective June 1, 2021), applicants must file a written declaration within 12 months and submit a copy of the first application within three months to establish domestic priority right; otherwise, the earlier application will be deemed withdrawn. In practice, enterprises often fail to establish priority right due to missed copy submission deadlines or inconsistent subject matter; some are also caught off guard by the unexpected withdrawal of the original application. Hengluo Lawyers usually recommend: establishing a priority right database immediately after the first application, and clearly defining the boundaries of the same subject matter. For major portfolios, it is advisable to seek assistance from professional agencies to conduct comprehensive patentability assessments and optimize the structure of the portfolio.Special services and other case servicesCollaboration.

IV. Practical suggestions and legal basis

The legal basis is Article 29 of the Patent Law of the People's Republic of China (amended on October 17, 2020 and implemented on June 1, 2021) (National priority right for inventions and utility models: an applicant may enjoy priority right if he/she files an application for the same subject matter within twelve months from the date of the first application); Article 30 (the applicant shall submit a written statement and a copy of the first application within three months); and the provisions on foreign priority rights. Practical suggestions: immediately record the twelve-month deadline after the first application; the subsequent application must be written around the same subject matter; submit the written statement and the copy on time; and be aware that the original case will be deemed withdrawn, so plan for alternative protection in advance. For foreign-related applications, you can combine the above with relevant provisions.Financial capital and cross-border legal services involving foreign affairsEvaluate the Paris Convention pathway.

5. Hengluo Law Firm's Advice

Claim the right of priority in your own country, and remember the four key elements: "twelve months, the same subject matter, written statement, and timely submission of copies". The deadline starts from the date of the first application, with no lenient space for suspension or extension. It's essential to set reminders; the subject matter of the subsequent application must be the same as that of the first application, and the added content will not enjoy the right of priority. After claiming the right of priority, the original case is considered withdrawn, and it's necessary to evaluate whether to maintain the original protection at the same time. Enterprises should incorporate priority management into their IP records to avoid human-induced overdue situations. For unclear subject boundaries, it's recommended to consult a patent agent in advance to minimize procedural risks.

VI. Frequently Asked Questions

Q1: Can claiming national priority always guarantee that the application date will be preserved, or is there a chance of failure?

The domestic priority right does not automatically come into existence and must meet statutory conditions. If the subsequent application is filed within twelve months from the date of the first application, has the same subject matter, and a written declaration and a copy of the first application have been submitted, the priority right may be granted on the date of the first application; if any of the requirements are missing — such as exceeding the time limit, inconsistent subject matter, or failure to submit a copy — the priority right will not be established, and the subsequent application will only be based on its actual filing date, which may result in the loss of novelty advantages. Therefore, "claiming" does not equal "retaining", and the requirements must be checked item by item. It is recommended that a patent attorney verify the list of requirements before submission.

Q2: What materials are required to apply for national priority rights?

The core materials include: the application number and proof of the application date of the first application, the request letter of the subsequent application (including the written declaration of domestic priority), the copy of the first application (which must be submitted within three months after the filing), and the explanatory documents on the same subject. If the first application is for a utility model and the subsequent application is for an invention, it is also necessary to provide a clear demonstration of the consistency of the subject matter between the two applications. The availability of all required materials and compliance with the time limits are prerequisites for the establishment of priority rights. It is recommended to establish a time limit ledger to avoid the loss of priority rights due to the late submission of the copy.

Q3: How much does it cost to entrust an agency to claim priority rights?

The fees include the official charges stipulated by the China Intellectual Property Administration (such as priority claim fees, etc., according to the current fee standard) and the service fees of patent agencies. The agency fees are generally charged per case or according to the service content, and the specific fees shall be subject to the entrustment agreement. There is no unified government pricing. Compared with regular applications that do not claim priority, the incremental costs mainly lie in the submission of copies and the handling of declarations, which can generally be controlled. It is recommended to clarify the composition of the fees and agency fees when entrusting the agency, and to agree on the time limit for reminding obligations to reduce the risk of overdue payments.

Q4: How long does it usually take from claiming priority to obtaining authorization?

The domestic priority right itself does not change the review cycle. Subsequent applications will still proceed according to the regular review process for invention patents or utility model patents, with substantive review often taking several months to several years. The key time points are the "12-month filing period" and the "three-month copy submission period", both of which are rigid deadlines that cannot be extended. Therefore, the focus of time management is on timely submission, rather than the speed of review. It is recommended to plan immediately after the first application, set aside time for drafting and correction, and ensure that both deadlines are not exceeded.

Q5: If a company wants to claim national priority, what should they do specifically in the first step?

It is recommended to follow four steps: First, confirm the date of the first application and set the deadline for submitting the application within twelve months and the deadline for submitting the copy within three months; Second, determine whether the subsequent application and the first application belong to the same subject and remove the inconsistent content; Third, make a written declaration of national priority in the request and prepare a copy of the first application; Fourth, submit the subsequent application and complete the copy within the deadline, and be aware that the original case will be considered as withdrawn and arrange for alternative protection in advance. Keep all submission documents throughout the process and, if necessary, let a professional intellectual property team coordinate the work.
