How to check foreign invention patents and matters needing attention

With the continuous acceleration of globalization, patents have become one of the important means of intellectual property protection. Whether you are a patent applicant, patent researcher, lawyer or entrepreneur, you need to master the methods and skills of searching patent information in order to better understand market dynamics, avoid infringement, and even find business cooperation opportunities.

1. Query method

1. Use professional database

First of all, the internationally commonly used patent query database has become a powerful assistant. Databases such as the United States Patent and Trademark Office website (USPTO), the European Patent Office website (EPO), and the World Intellectual Property Organization website (WIPO) collect patent information from various countries. These databases not only provide detailed information such as patent claims, specifications, and legal status, but also provide powerful search and filtering functions to quickly obtain the required information. However, when using these professional databases, be sure to pay attention to the relevant charging standards and conditions of use to avoid unnecessary trouble.

2. Use professional query tools

In addition to professional databases, a range of patent search tools are available. For example, tools such as PatSnap and DerwentInnovation provide you with intelligent search functions, allowing you to accurately filter information based on multiple dimensions. The high accuracy and fast retrieval speed of these tools will greatly improve search efficiency and provide strong support for patent search work.

2. Preparation before query

Before conducting a patent search, some preparations are essential. First, understand the relevant intellectual property laws, regulations and professional terms so that you can more accurately match and understand the query results. In addition, an in-depth understanding of the technical field and economic market conditions of the target patent will help you optimize your search conditions and obtain results that are more in line with your actual needs. If you need to search for foreign invention patents, you also need to master the laws, regulations, language and culture of the target country to ensure better use of relevant databases.

3. In-depth analysis of query results

After querying the patent, you will get multiple data such as patent-related information, legal status, and patent family. When obtaining these results, do not be quick to take them at face value but require careful analysis and dissection. An in-depth understanding of the scope of rights, cited documents, and patent family information will help you more accurately determine the validity and value of the patent you are querying. Through in-depth analysis, you can better support business decisions and avoid unnecessary risks.

4. Key steps in applying for foreign invention patents

1. Determine the country of application

Before applying for a foreign invention patent, you first need to determine the country or region where you are applying. This depends on your market strategy and the IP protection system of the target country. Generally speaking, you can choose countries or regions with more developed technology markets, such as the United States, European countries, China, Japan, etc. At the same time, you need to understand the patent laws and application procedures of the target country so that subsequent applications can be carried out smoothly.

2. Conduct patent search and evaluation

Before applying for a foreign invention patent, conducting a patent search and evaluation is a very important step. This can help you understand existing relevant technologies and patents, and evaluate whether your invention is innovative and patentable. Through patent search, you can discover existing similar patents, thereby providing guidance and reference for subsequent patent applications.

3. Prepare application materials

Applying for a foreign invention patent requires preparing a series of application materials. It mainly includes invention patent application, invention description, claims, drawings, etc. The preparation of application materials must comply with the patent laws and requirements of the target country to ensure the standardization and completeness of the materials. Sometimes translation and notarization are required to ensure the accuracy and legality of the materials.

4. Select application method

When applying for a foreign invention patent, you can choose different application methods. Common methods include direct application and international patent application (PCT application). Direct application refers to submitting application materials directly to the patent office of the target country. International patent applications are carried out through the International Patent Cooperation Treaty (PCT), and you can apply for patent protection in multiple countries internationally at the same time. Choosing the appropriate application method needs to be determined based on the specific circumstances and needs.

5. Pay application fee

A certain application fee is required to apply for a foreign invention patent. The amount and payment method of the fee depend on the regulations of the target country. Generally speaking, fees include application fees, search fees, review fees, etc. Also note that translation, notarization, and other patent office fees may need to be paid. It is important to understand the fee structure and payment methods in your target country in order to budget and plan your fees.

6. Patent application review and subsequent procedures

After applying for a foreign invention patent, you will undergo patent review and follow-up procedures. During the review process, the Patent Office will review the application materials, including evaluation of innovativeness, patentability and technical content. The review cycle varies by country and application volume, and generally takes several months to years. During the review process, the application materials may need to be modified and supplemented to meet the requirements of the patent office.

7. Patent protection period and annual fee payment

Once an invention patent is authorized, you also need to pay attention to the patent protection period and annual fee payment. Different countries and regions have different patent protection periods, usually 20 years. During the protection period, a certain annual fee needs to be paid every year to maintain the validity of the patent. The amount and payment method of the annual fee vary by country and patent type, and need to be paid in a timely manner to ensure continued protection of the patent.

Conclusion

By using professional databases and query tools, making adequate preparations, and in-depth analysis of query results, you will be able to better obtain valuable intellectual property information and business opportunities. In today’s highly competitive market, mastering these skills will put you in a more advantageous position in the field of intellectual property. At the same time, in the process of applying for a foreign invention patent, you must correctly select the country to apply for, conduct patent search and evaluation, prepare application materials, choose the application method, pay the application fee, undergo patent review and follow-up procedures, and pay attention to the patent protection period and annual fee payment. It will provide innovators with a broader market and more comprehensive intellectual property protection.
