Report on the Differences Between Chinese and American Patent Systems and Application Processes By PatentPro.tech

1.????? Introduction

In the modern globalized knowledge economy, the patent system plays a vital role, especially in promoting innovation and technology transfer. Patents not only protect the rights of inventors but also drive technological progress and economic development. In this context, understanding the differences between patent systems in different countries is essential for international business and research activities. This report aims to conduct an in-depth analysis of the key differences between the patent systems and application processes in China and the United States, the world's two largest economies.

The United States established its first patent law in 1790, while China formulated its first patent law in 1984. These timelines mark the different starting points and backgrounds in the development of intellectual property protection in the two countries. The purpose of this report is to explore the development of these two patent systems from their inception to the present, focusing on the similarities and differences in eight key aspects, including application principles, scope of protection, duration of protection, applicant qualifications, application procedures, authorization document modifications, provisional patent applications, and national priority.

By comparing and analyzing these aspects, this report not only helps to understand the basic frameworks of the Chinese and American patent systems but also provides practical guidance for individuals and institutions seeking to apply for and maintain patent rights in these countries. It serves as not only a comparative study of patent law but also an important reference for promoting cross-border technology cooperation and exchanges.

2.????? Overview of Chinese and American Patent Systems A. Foundations of the American Patent System

1)????? The American patent system originated in 1790 and has undergone numerous changes in its key characteristics and principles. Initially based on the principle of first to invent, it shifted to the first inventor to file principle since March 16, 2013. The United States has a "grace period," which allows inventors to apply for a patent within one year of publicly disclosing their invention, and such disclosure will not affect the validity of the patent application. The scope of protection under American patent law is broad, encompassing new and useful methods, machines, products, or compositions of matter, or useful improvements thereof. Even areas not typically protected in most countries, such as plant varieties, pure software, business methods, and internet methods, may be patented in the United States.

2)????? Foundations of the Chinese Patent System China's patent system began in 1984 and follows the principle of first to file, granting the patent right to the person who files the application first for the same invention. In contrast to the United States, the scope of protection under Chinese patent law is more limited, generally not including areas that may be patented in the United States. The types of patents protected in China include inventions, utility models, and designs. Additionally, the duration of protection varies depending on the type of patent, with utility model patents lasting 10 years, design patents 15 years, and invention patents 20 years.

3)????? Key Goals and Principles of Both Systems Despite their distinct implementation, both the United States and Chinese patent systems aim to promote technological innovation and protect the intellectual property of inventors. The broad protection scope and grace period policy of the American system reflect its emphasis on the flexibility of innovation. Meanwhile, the Chinese system places more emphasis on application priority and clear protection durations, reflecting a strict approach to establishing and protecting patent rights. These differences not only reflect the respective legal and cultural backgrounds of the two countries but also present different challenges and opportunities for cross-border innovation and intellectual property protection.

3.????? Comparison of Patent Application Processes

1)????? American Patent Application Process

A.???? Steps:

a)??? Pre-search (optional): Conduct a prior art search to assess the patentability of the invention and determine its novelty. This step is not mandatory but helps to avoid duplicating existing technology.

b)?? Application submission: Include detailed specifications, claims, abstracts, and drawings. The specifications should describe the invention in detail and demonstrate its implementation.

c)??? Examination process: The USPTO examiner thoroughly reviews the application to ensure it meets the standards of novelty, non-obviousness, and utility.

d)?? Responding to examination opinions: If the examiner raises any questions or objections, the applicant must provide detailed responses and suggested modifications.

e)??? Grant: After successfully resolving all issues, the USPTO will grant the patent.

B.????? Subsequent options: Applicants can choose to continue the application (including continuation applications, divisional applications, and partial continuation-in-part applications) to address multiple inventive points or submit a provisional patent application to establish an earlier filing date.

?

C.???? Time limits:

a)??? A provisional patent application must be converted into a regular application within 1 year.

b)?? The response deadline for examination opinions is three months from the issue date, extendable by up to an additional six months.

2)???Chinese Patent Application Process

A.???? Steps:

a)??? Application submission: Submit a complete application document, including specifications, claims, abstracts, and drawings. The specifications need to describe the invention in sufficient detail for technical personnel to understand and implement it.

b)?? Preliminary examination: The National Intellectual Property Administration (NIPA) conducts a formal examination to ensure all necessary documents are provided and conform to prescribed formats.

c)??? Request for substantive examination: A request for substantive examination must be filed within 36 months of the application submission, and the examiner will thoroughly evaluate the novelty and creativity of the invention (this step is generally not required for utility model and design patents).

d)?? Responding to examination opinions: If the examiner raises any questions or objections, the applicant must provide sufficient responses and make necessary document modifications.

B.????? Grant: After satisfying all examination requirements, the invention will be granted a patent.

C.???? Time limits:

a)??? The deadline for requesting substantive examination is 36 months after application submission.

3)????? C. Analysis of Process Differences

A.???? The American patent application process offers more flexibility and subsequent options, such as provisional patent applications and continuing applications, which help to address complex inventive situations and protection strategies.

a)??? For authorized patents, the American Patent Law allows for modifications to already granted patent application documents, including certificate corrections, reissue applications, modifications during ex parte reexaminations, and modifications during inter partes reviews.

b)?? The United States permits inventors to submit a Provisional Patent Application (PPA) to establish an early filing date within 12 months of a regular application, at a lower filing fee and with simplified procedures.

c)??? After receiving a Final Office Action (FOA) in the United States, applicants are not only able to appeal but also file a continuing application, which includes continuation applications, divisional applications, and continuation-in-part applications submitted under the conditions stipulated in 35 U.S.C. 120, 121, or 365(c) and 37 CFR 1.78(a).

B.????? In contrast, the Chinese patent application process places more emphasis on standardization and strict time limits to ensure the formalities of applications and the efficiency of examinations. These differences reflect the different strategies and legal systems employed by the two countries in protecting intellectual property.

a)??? Modifications to authorized patent documents are highly restricted and generally limited to obvious errors and responding to invalidation requests.

b)?? If obvious errors are found in patent documents, according to Article 58 of the "Patent Law Implementation Rules", the State Intellectual Property Office is responsible for promptly correcting errors in the patent announcement or the patent single volume and announcing the corrections made. When a patentee discovers evident errors in the authorized text, they can submit a "Request for Correction of Errors" to the National Intellectual Property Administration to request the modification of such errors.

c)??? During the response period in the patent invalidation process, the patentee has the right to modify the patent documents within the specified time. These modifications should adhere to the following principles: firstly, the original title of the claim should not be changed; secondly, the scope of protection of the original patent should not be expanded in comparison to the authorized claims; thirdly, the modifications should not exceed the scope recorded in the original description and claims; and lastly, generally, it is not allowed to add technical features that were not included in the authorized claims.

4.????? Differences in Patent Nature and Types

1)????? Patentable Subject Matter China and the United States exhibit significant differences in terms of what can be patented. Specific comparisons in various fields are as follows:

A.???? Biotechnology:

a)??? United States: Allows for patent protection of technologies such as CRISPR gene editing. Biomedicine, such as proteins and antibodies, may be patented if they meet novelty and non-obviousness requirements.

b)?? China: Takes a more cautious approach to gene editing technologies involving human genes or embryos. Biomedicine patents require detailed experimental data and usage instructions. Ethical considerations play a significant role in biotechnology patent examinations in China.

B.????? Electronics Information:

a)??? United States: Relatively lenient towards software and algorithm patents, especially when integrated with hardware, such as mobile applications, cloud computing solutions, etc., which typically qualify for patent protection.

b)?? China: Places more emphasis on the technicality of software and algorithms, requiring them to be combined with specific hardware to achieve technical improvements or provide technical solutions.

C.???? Chemical Materials:

a)??? United States: Permits patent protection for new compounds, formulations, and their synthesis methods.

b)?? China: Also protects new compounds and their preparation methods but may have more specific requirements for using patents, such as clearly stating the innovative and effective new uses. In the chemical field, environmental safety and sustainability are crucial aspects of the review process in China.

2)????? Types of Patents:

A.???? China: Types of patents include inventions, utility models, and designs. The "utility model" patent, unique to Chinese patent law, offers protection for smaller inventions or improvements.

B.????? United States: Types of patents include inventions, plant patents, and design patents. Under American patent law, plant patents is distinct types not categorized separately in Chinese patent law.

5.????? Disclosure Requirements and Scope of Protection

1)????? Differences in disclosure requirements and scope of protection between Chinese and American patent applications are primarily reflected in the following aspects:

A.???? Disclosure requirement differences:

a)??? United States: The American Patent Law requires applicants to disclose what they consider to be the best mode of implementing the invention, which is part of the inventor's duty of honesty and credit. During the application process, applicants are required to provide the USPTO with information about any prior art they are aware of related to the application, known as the statement of prior art disclosure

This is an important component of American patent law, ensuring that all relevant prior art is considered during examination to assess the novelty and creativity of the invention.

b)?? China: Chinese patent law also requires inventors to fully disclose their inventions to ensure that technically skilled persons in the field can implement the invention based on the disclosure. However, the requirement for "best mode" is not as stringent as in the United States, with greater emphasis on providing sufficient details to enable the technical solution.

B.????? Scope of protection differences:

a)??? United States: The scope of protection in the United States is defined by the claims and can be interpreted relatively broadly. In some cases, products or methods that do not directly fall within the literal scope of the claims may still be considered infringing if they are equivalent to the elements described in the claims.

b)?? China: The scope of protection in China is also determined by the claims, but the interpretation of claims is generally more strict and literal. Chinese patent law differs from the United States in the application of the doctrine of equivalents. In the United States, the doctrine of equivalents applies only to non-substantive elements. In Chinese determinations of equivalent infringement, courts in some regions tend to afford less protection to the non-inventive technical features than the inventive features. For example, the Beijing High People's Court Guidelines for Patent Infringement Determination stipulate that: "For non-inventive technical features in inventive claims, modified technical features, or those in utility model claims, if the patentee knew or could reasonably foresee alternative technical features during the application or modification process but did not include them within the scope of protection, the patentee cannot claim such alternative technical solutions as equivalent features during infringement determination."

C.???? Clarity and support requirements:

a)??? United States: The American Patent Law requires claims to be clear, definite, and supported by the specifications and drawings. This means claims must be specific enough to determine their scope of protection.

b)?? China: Chinese patent law also has similar requirements and emphasizes that claims should be fully and accurately supported by the specifications. There is a stricter requirement for consistency between claims and specifications in China.

D.???? In summary, although China and the United States share certain commonalities in disclosure requirements and scope of protection in patent applications, there are significant differences in the specific implementation standards and interpretations. These differences are crucial for applicants seeking international patent protection to consider when preparing their applications.

2)????? Best Mode and Sufficient Detailed Technical Solution Requirements

A.???? Best Mode in the United States:

a)??? Definition: Requires inventors to disclose what they believe to be the best way to implement their invention, which is a subjective standard emphasizing the inventor's honest disclosure of the best implementation and use method at the time of application.

b)?? Legal consequences: Failure to disclose the best mode no longer results in patent invalidation, but it remains a requirement for patent applications.

B.????? Sufficient Detailed Technical Solution in China:

a)??? Definition: Requires the patent application to provide sufficiently detailed technical solutions and implementation methods to enable technically skilled persons to implement the invention, which is an objective standard.

b)?? Legal consequences: Failing to provide a sufficient detailed technical solution may lead to rejection of the patent application or revocation of the patent right.

3)????? Scope of Protection Differences

A.???? Scope of Protection in the United States:

a)??? The scope of protection in the United States is broad, encompassing new and useful methods, machines, products, or compositions of matter, even including pure software, business methods, and internet methods.

b)?? Types of patents: Inventions, plant patents, and design patents.

B.????? Scope of Protection in China:

a)??? The scope of protection in China is more limited, requiring software and algorithms to demonstrate technical improvements when combined with specific hardware.

b)?? Types of patents: Inventions, utility models, and designs.

c)??? Specific requirements: In chemical and computer fields, Chinese regulations may be more stringent, requiring assessment of the environmental impact and safety of chemicals or specific technical solutions and clear technical effects.

6.????? Prior Art Search and Examination Standards

1)????? Differences in Prior Art Search:

A.???? United States: Conducting a prior art search before formally applying is an optional step. This process aims to evaluate the patentability of the invention, particularly its novelty and non-obviousness. It is not mandatory but helps determine whether the invention may meet the basic requirements for patent grant.

B.????? China: Patent novelty searches are conducted to assess whether an invention is novel, i.e., whether it was previously unknown or in the public domain before the search date. This search typically includes patent literature, scientific journals, technical books, product samples, etc. Due to the vast amount of literature, this search is complex and challenging. Applicants can choose to conduct the search themselves or commission the Patent Literature Service Center of the China National Intellectual Property Administration, patent service agencies, or scientific and technical information institutions. Novelty searches are not mandatory, but patents for utility models and designs generally undergo less substantive examination. Therefore, patents without novelty searches may be vulnerable to invalidation.

2)????? Novelty:

A.???? United States: Requires that the invention not be known to the public before the application date. The focus is on assessing whether previous patent applications, academic papers, product releases, etc. have disclosed identical technical content. The novelty standard in the United States, to some extent, converts the date of the inventor's first public disclosure into the criterion for judging novelty, i.e., in some cases, the application date is no longer the benchmark for judging novelty. The American Patent Law stipulates exceptions to the judgment of novelty: (1) Disclosures by the inventor himself/herself within one year before the application date do not constitute prior art and will not destroy the novelty of the invention being sought; (2) When the inventor and others have disclosed the invention within one year before the application date, if the inventor's disclosure is earlier than the others', then the others' disclosure also does not constitute prior art and will not destroy the novelty of the invention being sought.

B.????? China: Requires that inventions, utility models, or designs not have been publicly disclosed domestically or internationally before the application date. This includes any form of public disclosure, such as published papers, public exhibitions, etc.

3)????? Creativity and Non-Obviousness：

A.???? United States: The assessment of non-obviousness employs the "teaching-suggestion-motivation" test, considering whether the invention would be obvious to a person skilled in the relevant technical field.

B.????? China: The evaluation of inventiveness focuses on the current state of the technical field, the limitations of existing technology, and whether the invention offers significant improvements compared to existing technology.

4)????? Utility: Both countries require: The invention must have industrial applicability, reproducibility, and provide clear technical effects. The United States places more emphasis on the practicality and effectiveness of the invention, while China emphasizes that the invention must produce positive effects, meaning it must have practical application value beyond being merely a theoretical idea or abstract concept.

7.????? Patent Costs and Maintenance

1)????? Application Fees, Annual Fees, and Maintenance Fee Comparisons:

A.???? China: In China, invention and utility model patents require the payment of annual fees to maintain the patent right. If the annual fee is not paid on time, there is a grace period, but a surcharge must be paid. If the fee is not paid during the grace period, the patent right will terminate. Application fees and annual fees vary depending on the type of patent, with application fees being relatively low, while annual fees increase incrementally as the patent expires.

B.????? United States: In the United States, only invention patents require the payment of maintenance fees, while design and plant patents do not. Maintenance fees must be paid at specific time windows after the grant of the patent (3.5, 7.5, and 11.5 years). Failure to pay the maintenance fee on time will result in the invalidation of the patent right. Patent application fees are higher in the United States, especially when considering additional attorney fees and maintenance fees. Invention patent annual fees are due at 3-3.5 years, 7-7.5 years, and 11-11.5 years after grant.

The United States Patent and Trademark Office (USPTO) charges the following fees for patents:

2)????? Fee Reduction Policies:

A.???? China: Eligible applicants in China can enjoy fee reductions of up to 85% on application fees and annual fees according to regulations.

B.????? United States: The USPTO offers fee reductions on maintenance fees for small and micro entities. Independent inventors, nonprofit organizations, and enterprises with fewer than 500 employees are classified as small entities and are eligible for lower fees, usually half of the rates for non-small entities.

8.????? Patent Licensing and Transfer

1)????? License Agreement and Transfer Processes:

In both China and the United States, the processes for patent licensing and transfer differ but are important parts of commercialization strategies for patents.

A.???? China:

a)??? Patent licensing: Patentees can license their patents to other entities or individuals for use, which can be exclusive or non-exclusive. Exclusive licenses mean that, except for the patentee and the licensee, no third party has the right to use the patent. Patent license contracts must be filed with the National Intellectual Property Administration.

b)?? Patent transfer: Patent rights can be transferred to other individuals or entities. The transfer requires executing a transfer agreement and applying to the National Intellectual Property Administration for registration of the transfer of patent rights.

B.????? United States:

a)??? Patent licensing: License agreements are highly flexible and can be tailored to the business needs of both parties. Licenses can be exclusive, non-exclusive, or partially exclusive.

b)?? Patent transfer: Patent rights can be sold, assigned, or otherwise transferred to another individual or entity. The transfer requires executing an assignment agreement and recording the assignment with the USPTO.

2)????? Legal Requirements and Practical Differences

In both China and the United States, licensing and transferring patents can bring economic benefits to the patent holder. However, there are differences in the specific operational details, costs, and legal requirements between the two countries:

A.???? In China, patent licensing and transferring must comply with the regulations and procedures of the National Intellectual Property Administration. This involves following specific guidelines for documentation, approval processes, and adhering to national patent laws.

B.????? In the United States, there is greater flexibility in terms of patent licensing and transferring, but it still requires adherence to the regulations set by the United States Patent and Trademark Office (USPTO). The USPTO sets forth requirements for documentation, recording of the transfer, and other legal formalities, although they might offer more leeway in terms of negotiation and structuring of the agreements.

Given the differences in how China and the United States handle patent licensing and transferring, it is advisable to consult with a professional lawyer before executing any patent licensing or transferring agreements to ensure compliance with the relevant legal regulations in each respective country. This helps in navigating the legal complexities and ensures that the patent rights are protected and legally enforceable in both jurisdictions.

3)????? Enforcement of License Agreements and Transfers:

A.???? China: The enforcement of license agreements and transfers is governed by Chinese contract law and intellectual property laws. If there is a dispute over the terms of the agreement or the performance of the agreement, the parties can seek resolution through mediation, arbitration, or litigation.

B.????? United States: The enforcement of license agreements and transfers is governed by federal law and state law. If there is a dispute over the terms of the agreement or the performance of the agreement, the parties can seek resolution through mediation, arbitration, or litigation.

4)????? Patent Litigation and Dispute Resolution

A.???? A. Litigation Procedures:

a)??? China: Patent litigation in China is generally handled by the specialized intellectual property courts or tribunals. The procedures are similar to general civil litigation procedures, with a focus on written submissions and evidence.

b)?? United States: Patent litigation in the United States is generally handled by federal district courts. The procedures are similar to general civil litigation procedures, with a focus on written submissions and evidence.

B.????? Alternative Dispute Resolution:

a)??? China: Alternative dispute resolution options include mediation and arbitration. Mediation is often used as a preliminary step to resolve disputes before litigation. Arbitration is also an option, but it is less common in China than in the United States.

b)?? United States: Alternative dispute resolution options include mediation, arbitration, and mini-trials. Mediation is often used as a preliminary step to resolve disputes before litigation. Arbitration is also an option, and it is more common in the United States than in China. Mini-trials are used to narrow the issues in dispute before full litigation.

9.????? Detailed Guide for American Inventors Applying for Patents in China:

1)????? Application Path and Considerations

A.???? Understanding the Paris Convention's Priority Principle

a)??? First Application: Initially submitting a patent application in the United States (a member country of the Paris Convention).

b)?? Priority Right: This application grants you the right of priority when submitting the same invention for a patent application in other Paris Convention member countries.

c)??? Window Period: Within 12 months of the initial application, you can submit applications in other member countries (such as China) and enjoy the priority of the initial submission date.

B.????? Choosing the Application Path

a)??? Via PCT Application: Submit an international application through the PCT, then choose to enter the Chinese national phase within 30 months of the international application date.

b)?? Direct Application: Directly submit an application to the China National Intellectual Property Administration (CNIPA) within the 12-month priority period.

C.???? Preparing Application Documents

a)??? Document Contents: Include a description, claims, and abstract.

b)?? Language Requirements: All documents must be translated into Chinese.

D.???? Choosing a Patent Agent

a)??? Agent Requirement: Typically, foreign applicants need to appoint a patent agent registered in China.

E.????? Submitting the Application

b)?? Professional Consultation: Given the complexity of the patent application, it is advisable to seek help from a professional agent throughout the process.

c)??? Maintaining Patent Rights: After obtaining the patent, annual fees must be paid as required to maintain the patent rights.

By following these steps, American inventors can effectively apply for and obtain patent protection in China. Each step is crucial to ensuring that your invention is properly protected globally.

2)????? Applying for a patent via the PCT (Patent Cooperation Treaty) route and then entering the national phase in China can save costs in certain aspects, mainly reflected in the following areas:

A.???? International Search Report and Written Opinion: When applying through the PCT route, you will receive an International Search Report (ISR) and a Written Opinion. These documents are crucial for understanding the novelty, inventiveness, and industrial applicability of the invention. In the national phase in China, these reports can be referenced by the China National Intellectual Property Administration (CNIPA), potentially reducing the workload of examination in the national phase, thus saving costs. (Each country's intellectual property office or patent office conducts searches and reviews for national phase applications based on their patent laws and is not limited to the results of the PCT international search report and written opinion. However, examiners in each country will carefully study the international search report and written opinion during the examination of PCT national phase applications, especially focusing on the content about novelty and inventiveness.)

B.????? Unified International Phase: The PCT application allows applicants to modify and improve their application during a unified international phase, which helps to improve and optimize the patent application before entering the national phase in China, potentially reducing the number of modifications in the national phase and lowering costs.

C.???? Extended Decision-Making Time: The PCT application provides applicants with more time to decide whether to apply for the national phase in China (or other member countries). This means that applicants can better assess the commercial value and success probability of their patent before investing more resources.

D.???? Preliminary Assessment: The international search report and written opinion of the PCT provide a preliminary assessment of the application's potential, helping applicants to predict the possible results of substantive examination in China, thus avoiding unnecessary examination fees for applications with little probability.

E.????? However, it should be noted that the PCT application itself incurs additional costs, including international search fees, international application fees, etc. Therefore, whether it saves costs needs to be considered based on the total costs of the international phase and the national phase in specific situations.

F.?????? Overall, applying for a patent through the PCT route and entering the national phase in China can provide advantages in improving application quality, optimizing application strategy, and predicting the success rate of the application, thereby potentially indirectly saving some costs. However, whether it is cost-effective needs to be determined based on specific circumstances and the specific content of the patent.

10.? Technical Disclosure Differences and Guidelines

1)????? Overview of Technical Disclosure in the United States

A.???? In the United States, a technical disclosure is an important part of a patent application. It needs to describe the invention in detail, including its technical background, detailed description, embodiment(s), and at least one specific implementation example.

B.????? U.S. patent law requires inventors to provide sufficient information to enable other professionals in the field to implement and use the invention. Additionally, U.S. patent law also requires the inventor to disclose what they consider the best mode of implementation.

2)????? Technical Disclosure in China

A.???? Detail Requirements: Technical disclosures in China are more stringent, requiring a more detailed description of the invention and examples. This includes the background of the invention, the content of the invention, the technical solution, beneficial effects, etc.

B.????? Importance of Examples: In China, examples are crucial for demonstrating the feasibility of an invention. Usually, multiple examples are needed to fully showcase different applications of the invention.

C.???? Algorithm and Software-Related Inventions: For algorithm and software-related inventions, Chinese patent law requires specific implementation methods and how the algorithm or software integrates with hardware to achieve the intended technical effect.

D.???? Drawings and Diagrams: In Chinese patent applications, drawings and diagrams are very important components, and they need to clearly and detailedly show the structure and working principle of the invention.

3)????? Writing Suggestions
