Common Business Guide

2.1 Preparation of Application Documents

The preparation of application documents is a crucial step in the intellectual property application process. Requirements for application documents vary depending on the type of intellectual property.

Patent applications typically require the following documents: application request, specification, claims, drawings (if any), and abstract. The specification should provide a clear and complete description of the invention, enabling a person skilled in the art to implement it. The claims should clearly and concisely define the scope of patent protection sought.

Trademark applications require the following documents: application form, trademark sample, and a list of designated goods or services. The trademark sample should be clear and identifiable, meeting the specified size requirements. The designation of goods or services should comply with the Nice Classification.

Design patent applications require the following documents: application form, design drawings or photographs, and a brief description. The drawings or photographs should clearly show all features of the design, typically including six views (front, back, left, right, top, and bottom views).

2.2 Fee Payment

The intellectual property application and maintenance process involves multiple fees. These mainly include application fees, examination fees, registration fees, and annual fees. The specific amounts and payment times may vary depending on the type of intellectual property and specific circumstances.

Applicants can pay fees through various methods, including online payment, bank transfer, and postal remittance. It is recommended that applicants familiarize themselves with fee standards and payment methods before submitting applications, and pay all fees promptly to avoid applications being deemed withdrawn or rights terminated due to late payment.

The Patent Office website provides the latest fee standards and payment guidelines, which applicants can consult at any time. Fee reductions may be available for eligible small and medium-sized enterprises, individuals, etc.

2.3 Responding to Examination Opinions

During the examination process of intellectual property applications, examiners may issue examination opinion notices pointing out problems or deficiencies in the application. Applicants need to respond to these opinions within the specified time limit.

When responding to examination opinions, applicants should address each issue raised by the examiner in detail with explanations and arguments. For patent applications, it may be necessary to amend the specification or claims to overcome novelty or inventiveness defects pointed out by the examiner. For trademark applications, it may be necessary to modify or restrict the trademark sample or the designated goods and services.

When responding, applicants should note the following: Strictly adhere to response deadlines, applying for extensions if necessary. Responses should be objective and comprehensive, providing necessary supporting evidence. When amending application documents, care should be taken not to exceed the scope of the original application. If disagreeing with the examination opinion, provide sufficient reasons and evidence.

2.4 Rights Maintenance

Obtaining intellectual property rights is only the first step; effective maintenance and management of these rights are equally important. Rights maintenance mainly includes several aspects: Timely payment of annual fees: For patent rights, annual fees must be paid starting from the year of grant to maintain the validity of the rights. Attention to protection periods: Different types of intellectual property have different protection periods, such as 20 years for invention patents, 10 years for utility models and designs, and 10 years for trademarks (renewable). Active monitoring of infringement: Rights holders should actively monitor the market to promptly detect and stop infringement. Reasonable utilization of rights: Realize the value of intellectual property through licensing, transfer, and other means. Timely rights evaluation: Regularly assess the value of intellectual property as a basis for corporate asset management. An effective rights maintenance strategy can maximize the value of intellectual property, creating sustainable competitive advantages for enterprises.

Frequently Asked Questions (FAQ)

3.1 How can I check the progress of my application?

Answer: Checking the progress of your application is an important part of the intellectual property application process, helping applicants stay informed about the latest status of their application. Applicants can access this information through the dedicated inquiry system provided on the Patent Office’s official website. First, visit the official website of the Patent Office and look for the “Application Inquiry” or similar entry on the homepage. After entering the inquiry page, you need to input your application number. The application number usually consists of a year and a string of numbers, with the format varying slightly depending on the type of application.

After entering the application number and submitting the inquiry, the system will display your application’s current status, important date information, and examination progress details. This information may include the application’s filing date, publication date, substantive examination request date, and whether there are any examination opinion notices. It’s worth noting that system updates may have a 1-2 working day delay, so if you’ve recently submitted documents or paid fees, you may need to wait a few days to see the corresponding updates in the system.

Additionally, most Patent Offices offer mobile applications or SMS notification services, which you might consider using for more convenient tracking of your application progress. If you encounter any problems while using the inquiry system, it’s advisable to contact the Patent Office’s customer service department for assistance.

3.2 How long does it typically take from patent application to grant?

Answer: The time from patent application submission to final grant can vary due to multiple factors. On average, an invention patent typically takes 2-3 years from application to grant. However, this timeframe can vary significantly depending on factors such as the complexity of the technical field and the quality of the application.

In some technical fields, such as biotechnology or computer software, the examination process may be longer due to the complexity and rapid development of the technology. In contrast, some relatively traditional or mature technical fields may have faster examination speeds. The quality of the application documents is also an important factor affecting examination time. Well-prepared applications with clear descriptions can expedite the examination process, while poor-quality applications may require multiple amendments, thus prolonging the entire process.

Moreover, factors such as the Patent Office’s workload, the speed of applicants’ responses to examination opinions, and whether priority examination is involved all affect the final grant time. It’s worth noting that utility model patents and design patents usually have shorter examination times, possibly only requiring 6 months to a year.

Applicants can take several approaches to shorten the examination time, such as submitting high-quality application documents, responding promptly to examination opinions, or applying for priority examination when eligible. Additionally, patent prosecution highway programs between some countries may help accelerate the examination process. Applicants should choose suitable strategies to manage the patent application process based on their specific situations and needs.

3.3 What should I do if I miss the deadline for responding to an examination opinion?

Answer: Missing the deadline for responding to an examination opinion is a serious issue in the patent application process and may result in the application being deemed withdrawn. However, applicants still have opportunities for remedy. First, you can submit a request for restoration of rights. This needs to be done promptly, usually immediately after realizing the missed deadline. When submitting a request for restoration of rights, the applicant needs to provide a detailed explanation of the reasonable grounds for missing the deadline, such as sudden illness, natural disasters, or other force majeure factors. At the same time, a corresponding restoration fee needs to be paid.

In addition to submitting the restoration request, the applicant also needs to submit a response to the examination opinion simultaneously. This means not only explaining the reason for missing the deadline but also substantively addressing the issues raised by the examiner. It should be noted that the request for restoration of rights does not guarantee approval; the Patent Office will review it based on the specific circumstances.

To avoid falling into this predicament, the best practice is to respond to examination opinions promptly within the original deadline. If you anticipate being unable to complete the response within the deadline, you can apply for an extension in advance. Most national patent offices allow applicants to apply for an extension of the response period under specific conditions. Furthermore, establishing an effective date management system, such as using specialized intellectual property management software or setting up multiple reminders, can greatly reduce the risk of missing deadlines.

Lastly, hiring a professional patent agent is also a wise choice. They typically have well-established deadline management systems and extensive experience, which can help applicants avoid such issues and provide professional advice and assistance when problems arise.

3.4 How long after trademark registration do I need to renew?

Answer: Trademark registration is an important means of brand protection, but it is not a one-time effort. Trademarks need to be renewed periodically to maintain their validity. According to the laws of most countries, including China, the validity period of trademark registration is 10 years. This means that from the date of registration, the trademark owner has exclusive rights for 10 years.

However, trademark owners should not wait until the 10-year period is about to expire before considering renewal. Typically, the law stipulates that renewal applications can be filed within 6 months before the expiration of the trademark registration. This time window is crucial as it gives trademark owners ample time to prepare the renewal application while avoiding the risk of losing trademark rights due to forgetfulness.

It’s worth noting that some countries also have a “grace period”. For example, even if the normal renewal deadline is missed, renewal can still be applied for within 6 months after the trademark expires, but additional late fees may be required. However, not all countries have such grace periods, so the safest approach is to complete the renewal within the normal renewal period.

The trademark renewal process usually includes submitting a renewal application form, paying renewal fees, and sometimes providing proof of trademark use. To ensure smooth renewal, trademark owners should plan ahead, setting up reminder systems or entrusting professional trademark agencies to manage renewal matters. This can prevent the loss of valuable trademark rights due to negligence and ensure continuous legal protection for the brand.

3.5 Can I apply for both an invention patent and a utility model patent simultaneously?

Answer: Yes, it is possible to apply for both an invention patent and a utility model patent simultaneously. This practice is known as “dual-track” application in patent practice. This strategy allows applicants to seek two different types of patent protection for the same technical solution. The main reason for choosing a “dual-track” application is that invention patents and utility model patents each have their own advantages.

Invention patents typically provide stronger and more durable protection, lasting up to 20 years, but the examination process is longer, potentially taking 3-5 years to grant. In comparison, utility model patents have a faster examination process, usually granting within a year, but have a shorter protection period of only 10 years.

Through a “dual-track” application, applicants can quickly obtain protection through a utility model patent while waiting for the examination results of the invention patent. This strategy is particularly suitable for fields where technology updates rapidly, allowing initial protection through a utility model patent while waiting for the invention patent to be granted.

However, it should be noted that although both types of patents can be applied for simultaneously, ultimately only one patent right can be chosen. This is because the law does not allow multiple patent rights for the same invention. Usually, when the invention patent is granted, the applicant needs to abandon the utility model patent right.

Furthermore, when adopting a “dual-track” application strategy, applicants need to declare at the time of submission that they have submitted another type of patent application. While this approach can provide a more flexible protection strategy, it also requires consideration of additional application fees and management costs. Therefore, when deciding whether to adopt a “dual-track” application, it is advisable for applicants to consult with patent agents and make the most suitable choice based on their own technical characteristics, market strategy, and budget considerations.

3.6 How to apply for fee reduction?

Answer: Various fees involved in patent application and maintenance processes can pose a significant financial burden on individual inventors and small-to-medium enterprises. To encourage innovation and support these groups, many national intellectual property offices offer fee reduction policies. The specific steps and requirements for applying for fee reduction may vary by country, but generally follow this process:

First, applicants need to confirm whether they meet the conditions for fee reduction. Typically, eligible applicants include individual inventors, small and micro enterprises, non-profit organizations, universities, and research institutions. Each country may have different definitions for “small and micro enterprises,” usually based on indicators such as the number of employees and annual turnover.

Second, applicants need to prepare relevant supporting documents. These may include proof of identity, proof of enterprise size, financial status documents, etc. For individual applicants, income proof or unemployment certificates may be required. For enterprises, business licenses and financial statements from the previous year may be necessary. Specific requirements should be checked on the official website of the patent office or by consulting a patent agency.

Next, applicants need to fill out a fee reduction application form. This form can usually be downloaded from the patent office’s official website or submitted along with the patent application. When filling out the form, applicants need to declare relevant information truthfully and attach the prepared supporting documents.

After submission, the patent office will review the application. The review time may vary depending on each country’s policies and workload. If the application is approved, the applicant can enjoy corresponding fee reductions in subsequent patent application and maintenance processes.

It should be noted that fee reduction policies may be updated periodically, and different types of fees may have different reduction ratios. Therefore, it is recommended that applicants regularly check the patent office’s official website to understand the latest reduction policies. At the same time, if the applicant’s conditions change (for example, a small enterprise develops into a large enterprise), they should promptly notify the patent office to avoid legal risks due to improper enjoyment of preferential treatment.

3.7 How to protect my rights if I discover someone infringing my patent?

Answer: Discovering that someone is infringing on your patent rights can be a serious challenge for patent holders. In such situations, patent owners have several options for protecting their rights, but each method has its advantages, disadvantages, and applicable situations.

First, negotiation is usually the quickest and least costly approach. The patent holder can directly contact the infringing party, explain the situation, and demand they cease the infringing activities and negotiate compensation. This method can avoid lengthy legal procedures and sometimes even establish future business cooperation. However, if the infringing party is uncooperative or denies the infringement, this approach may not achieve the expected results.

Second, filing an invalidation request with the patent office is another possible option. If the patent holder discovers that a patent owned by the infringing party may affect the exercise of their own patent rights, they can attempt to invalidate the other party’s patent through this method. The advantage of this approach is its relatively low cost, and the judgment is made by professional examiners. However, it should be noted that this method does not directly resolve the infringement issue, and if the request fails, it may strengthen the validity of the other party’s patent.

Lastly, filing a lawsuit in court is the most formal and legally binding way to protect one’s rights. Through litigation, the patent holder can demand the cessation of infringing activities, compensation for losses, and even apply for a temporary injunction in some cases. Court judgments have enforcement power and can effectively stop infringing behavior. However, the litigation process is often time-consuming, costly, and the outcome can be uncertain.

Regardless of which method is chosen, it is strongly recommended to first consult with a professional intellectual property lawyer. Professional lawyers can help assess the severity of the infringement, analyze the pros and cons of various rights protection methods, and formulate the most suitable strategy. They can also assist in collecting evidence, drafting legal documents, and representing the patent holder in negotiations or court appearances when necessary.

In addition, patent holders should consider taking preventive measures, such as regularly monitoring the market to promptly detect potential infringement; improving internal intellectual property management systems to ensure the validity and enforceability of their own patents; and considering patent licensing at appropriate times to convert potential infringers into partners.

3.8 What steps are needed to apply for an international patent?

Answer: Applying for an international patent is a complex but very important process for companies operating across borders or for inventions with international market potential. The Patent Cooperation Treaty (PCT) route is one of the most common and effective ways to apply for an international patent. This process involves multiple steps that require careful planning and execution by the applicant.

First, the applicant needs to file a PCT international application with their national patent office (in this example, the Japan Patent Office). This application should include a detailed description of the invention, claims, necessary drawings, and other documents that meet PCT requirements. After submitting the PCT application, the applicant obtains priority date protection in all PCT member countries. This is the starting point of the entire process and a crucial step in ensuring the validity of the international patent application.

After the PCT application is submitted, an international search will be conducted by a designated International Searching Authority, which will issue an international search report and written opinion. This report will list prior art documents that may affect the patentability of the invention, helping the applicant assess the likelihood of obtaining a patent. This step is very important for applicants as it provides valuable information that can help decide whether to continue with the application process.

Next, the PCT application is usually published 18 months after the priority date. After publication, the technical content of the invention will be disclosed to the world. Although this step seems simple, it is actually an important milestone in the patent application process as it marks the formal entry of the invention into the public domain.

After publication, the applicant can choose to request an international preliminary examination. This is an optional step, but it is very valuable for many applicants. It can help applicants further evaluate the patentability of the invention before entering the national phase and provides an opportunity to amend the application documents. This stage offers applicants a valuable opportunity to optimize their application before formally entering the examination procedures of various countries.

The most critical step in the PCT procedure is entering the national phase. Applicants need to decide in which countries they seek patent protection within 30 months (31 months for some countries) from the priority date and submit national phase applications in these countries separately. This step requires consideration of market strategy, budget, and other factors, and is one of the most complex and strategic decisions in the entire international patent application process.

After entering the national phase, patent offices in various countries will conduct substantive examinations according to their national laws. Applicants need to respond to the opinions of examiners from various countries and may need to amend application documents or provide additional arguments. This stage may last for a considerable time and may involve multiple rounds of communication and amendments.

Finally, if the application successfully passes the examination, patent offices in various countries will grant patent rights. Afterwards, the patent holder needs to pay annual fees in each country where the patent is granted to maintain the validity of the patent. This marks the completion of the international patent application process, but also begins a new phase of patent right maintenance.

3.9 How to search for published patent documents?

Answer: Searching for published patent documents is an important part of patent research, technological innovation, and intellectual property management. The patent search system provided by the patent office is one of the main tools for this work, but in fact, effective patent document searching requires mastering certain skills and strategies.

First, using the patent search system provided by the patent office is the most direct method. These systems usually have powerful search functions that allow users to search in various ways. Inputting keywords is the most common method, which requires users to have a certain understanding of the technical field being queried and be able to choose appropriate terms. In addition to using single keywords, Boolean operators (such as AND, OR, NOT) can be used to combine multiple keywords to improve the accuracy of the search.

Applicant searching is another effective method, especially when you want to understand the patent portfolio of a specific company or individual. This method can help analyze competitors’ technical layouts or find potential partners. However, it should be noted that a company may apply for patents under different names, so multiple searches may be necessary.

The International Patent Classification (IPC) number is a powerful but often overlooked search tool. The IPC system divides all technical fields into different sections, classes, subclasses, and groups, represented by combinations of letters and numbers. Searching through IPC classification numbers can help users quickly locate patents in specific technical fields, especially when accurate keywords are uncertain.

In addition to these basic methods, many patent search systems also provide advanced search options. For example, you can limit the search to a specific time range, patent type (such as invention patents, utility model patents, etc.), or the legal status of patents (such as granted, expired, etc.). These options can help users more precisely locate the required patent documents.

It is worth noting that although the patent office’s search system is an important resource, it may only include patent information from specific countries or regions. For users who need global patent information, they may need to use other resources, such as the PATENTSCOPE database of the World Intellectual Property Organization (WIPO), or some commercial patent databases.

Moreover, effective patent document searching also requires certain search strategies. For example, you can start with broader search conditions and then gradually narrow the scope based on the results; or start from known relevant patents and expand the search scope by checking their citations and cited situations.

Finally, it needs to be emphasized that patent document searching is a skill that requires continuous learning and practice. With the development of technology and changes in the patent system, search methods and tools are constantly updating. Therefore, frequently paying attention to relevant training and updates, and staying informed about the latest search techniques, is crucial for improving the efficiency and accuracy of patent document searches.

3.10 What to do if patent annuity fees are overdue?

Answer: Timely payment of patent annuity fees is crucial for maintaining the validity of patent rights. However, for various reasons, patent holders may find themselves in a situation where they have failed to pay annuity fees on time. While this situation is concerning, it is not entirely irretrievable. Understanding how to handle overdue annuity fees is very important for patent holders.

First, it should be clear that most countries’ patent laws have a grace period system. In Japan and many other countries, this grace period is usually 6 months. This means that even if the patent holder fails to pay the annuity fee by the specified payment date, they still have 6 months to remedy the situation. This system is established to give patent holders a buffer, avoiding the direct loss of patent rights due to temporary oversight or special circumstances.

During this 6-month grace period, patent holders can pay the overdue annuity fee. However, this late payment is not without cost. Usually, in addition to paying the original annuity fee, a certain amount of late fee must also be paid. The amount of the late fee may vary by country; some countries may have a fixed amount, while others may calculate based on the length of the delay. This additional fee can be seen as a penalty for not paying on time, and is also a necessary cost to maintain patent rights.

It should be particularly noted that if the annuity fee and late fee are still not paid within this 6-month grace period, the consequences will be severe. Beyond this period, the patent right will automatically terminate. This means that the invention will lose legal protection, and anyone can freely use the technology, while the original patent holder will not be able to prevent others from using it or claim compensation. The termination of patent rights may mean huge economic losses and loss of competitive advantage for enterprises.

In some special cases, the patent laws of some countries may allow patent holders to apply for rights restoration. This usually requires the patent holder to prove that the failure to pay on time was due to force majeure or other justifiable reasons. However, such rights restoration procedures are often complex, time-consuming, and have a low success rate, so they should not be considered as a regular option.

To avoid overdue annuity fees, patent holders should establish a strict patent management system. This may include setting up multiple reminder mechanisms, regularly reviewing the patent portfolio, and evaluating the value and necessity of maintaining each patent. For large enterprises or individuals owning numerous patents, considering the use of professional patent management software or hiring patent agencies to assist in management may be beneficial.

Furthermore, patent holders should regularly evaluate their patent portfolio. If a certain patent no longer has commercial value, they can consider actively abandoning it to save unnecessary annuity fee expenditures. This strategic patent management can help enterprises allocate resources more effectively and focus on maintaining truly important patents.
