[Direct answer]In the Beijing area, whether the scope of protection can be expanded when responding to review opinions depends on whether the amendments exceed the scope described in the original application documents. According to Article 33 of the Patent Law of the People's Republic of China (amended and implemented on June 1, 2021), amendments to invention and utility model patent application documents shall not exceed the scope described in the original specification and claims. In practice, most amendments made to respond to review opinions are aimed at overcoming rejection defects, and in nature, they should narrow or clarify the scope of claims, rather than expand the scope of protection by taking advantage of the opportunity; only when the original specification and claims already clearly support a broader scope and no new content is introduced, can the scope be adjusted appropriately. Whether the scope can be expanded ultimately depends on the content disclosed in the original application, rather than the applicant's subsequent intentions.

1. Problem background and typical scenarios

After receiving the notice of review opinions issued by the China Intellectual Property Administration, patent applicants often hope to gain an advantage by amending the claims, or even broadening the scope of the challenged claims to seek greater protection. Typical scenarios include: the examiner rejects the application for lack of novelty or inventiveness, and the applicant wants to expand the subject matter in another independent claim; mistakenly believing that the claims can be freely rewritten in the response stage, resulting in amendments that exceed the support of the original specification; and incorporating technical effects not described in the specification into the claims to claim broader protection. Once such amendments exceed the scope, they will not only be unacceptable, but may also be regarded as new content and not be reviewed.

II. Key points of contention

There are three main points of contention. Firstly, the modification of the scope of the boundaries: What does the original specification and claims describe? Does it only refer to the literal content, or does it also include the content that can be directly and unambiguously determined by professionals in the field? The review practice is relatively strict in this regard. Secondly, the modification purpose restriction: Is it allowed to actively expand the scope when responding to the review opinion? The review guidelines tend to only allow modifications to address the indicated deficiencies, and modifications exceeding this scope are generally not accepted. Thirdly, the support of the original application: Whether the broader scope claimed by the applicant is supported by specific examples or general descriptions in the original specification determines whether the modification can be recognized.

III. Professional analysis by Hengluo Law Firm

Based on practical experience in handling patent title confirmation and response operations, excessive modification is one of the most common hard flaws in responding to review opinions. Hengluo Lawyers usually suggest the following: Before responding, first compare the review opinions' pointed defects item by item to determine the minimum necessary scope of modification; the basis for modification must trace back to specific paragraphs and examples in the original specification, avoiding writing technical content that was verbally or subsequently supplemented into the claims; if it is necessary to adjust the scope of protection, priority should be given to methods such as generalizing dependent claims, which have a basis in the original records. For cases where the scope of protection is limited due to the limitations of the original application writing, it may be considered to apply for a separate case for restructuring rather than forcibly expanding the scope in the response. For complex creative disputes, it may be necessary to follow up with further legal procedures.Special services and other case-related servicesDevelop a strategy.

IV. Practical suggestions and legal basis

The core basis is Article 33 (amendment within the scope of the original description) and Article 22 (novelty, inventiveness, and practicality) of the Patent Law of the People's Republic of China (amended and implemented on June 1, 2021); the supporting provisions on amendments in response to review opinions in the Implementing Regulations of the Patent Law and the Patent Review Guidelines. Practical suggestions: After receiving the review opinions, first determine the type of defects and propose the minimum amendments accordingly; mark the sources of the original specification for each amended sentence; do not introduce new content or expand the scope without supporting evidence; when necessary, replace amendments with statements of opinions or request an extension of the deadline before it expires.

5. Henglu Law Firm's Advice

The reply to the review comments is not an opportunity to rewrite the patent. The amendments are strictly bound by the scope described in the original application. Remember: expanding the scope of protection must be based on clear support from the original specification. Adding or inserting new content out of thin air will not be accepted. It is recommended to conduct a self-inspection of the scope before submission, and if necessary, consult a patent agent or lawyer to avoid losing the possibility of authorization due to improper amendments or triggering subsequent invalidation risks. For enterprises with patent portfolios, they can take advantage of this opportunity to conduct a comprehensive review of their patent portfolio and make necessary adjustments to improve the quality of their patent applications and increase the chances of successful authorization.Business and contract dispute services for enterprisesOrganize ownership and implement licensing.

VI. Frequently Asked Questions

Q1: If I expand the scope of protection when responding to the review comments, will my application be directly rejected?

Expanding the scope of protection itself does not necessarily lead to a rejection, but modifications that exceed the scope described in the original specification and claims will not be accepted according to law. Reviewers will usually point out that the modification does not comply with Article 33 of the Patent Law and require it to be revised; if the applicant insists on it and cannot provide supporting evidence from the original records, the corresponding modified content will not be reviewed or will be deemed as not being proposed, and the case may maintain the original tendency to be rejected. Whether the patent can be granted depends on whether the remaining scope of protection still has novelty and creativity, rather than simply whether it can be expanded. Hengluo Law Firm advises making the minimum necessary modifications based on the original application to avoid a procedural stalemate caused by unsupported expansions.

Q2: I want to expand the scope of protection. What materials do I need to prepare to prove the support for the original application?

The core materials include: the finalized text of the original application documents (description, claims, drawings, and abstract), which are used to compare whether the modified content falls within the scope of the original disclosure; specific implementation examples, technical effect descriptions, and related paragraphs in the original description that support a broader scope; review opinion notifications and cited comparison documents, which are used to identify defects and determine the direction of modification; and a modification comparison table, which annotates the sources of each modification. The organization of evidence should focus on three points: the original application has been disclosed, the modification does not introduce new content, and there is a basis for a broader scope. The more complete the materials are, the higher the probability of the modification being accepted. It is crucial not to rely on memory to claim support.

Q3: If I hire a lawyer or an agent to respond to the review comments, what is the approximate cost?

The cost of patent responses is usually charged on a per-case basis, depending on the complexity of the review comments, the number of claims, and whether it is necessary to search for comparative documents. There is no unified national government pricing for this. For cases involving review, invalidation, or administrative litigation, the fees will be calculated separately. The specific amount shall be subject to the provisions of the contract. It is recommended to clarify the scope of services (whether it includes only responses or also includes amendment drafting and subsequent review), the billing method, and third-party expenses such as travel costs before entrusting the work. For important patents, it is advisable to evaluate the combined cost of responses and division of applications, review, and then invest based on the value of the patent authorization to avoid excessive spending on small-value patents.

Q4: How long does it usually take to respond to review comments, and what will happen if the deadline is exceeded?

Applicants should respond within the time limit specified in the Review Opinion Notice, which is usually two months from the date of receipt (with the option to request a one-month extension, subject to payment of fees and provision of justifications); failure to respond within the time limit will result in the application being deemed withdrawn. After the reviewer issues a rejection decision, there is a three-month period for requesting a review. Overall, it typically takes several months to a year from the initial response to either authorization or rejection, depending on the review process and whether the application enters the review stage. It is recommended that applicants establish a time limit schedule upon receiving the notice, set aside time for internal drafting and review, and avoid waiting until the deadline to process the application to prevent losing the application due to exceeding the time limit.

Q5: The review comments say that my content exceeds the scope. How should I modify it specifically to ensure it's compliant?

Here's the translation of the Chinese text into English: Suggested four steps: 1. Extract and review the defects pointed out in the review comments one by one, and categorize them into novelty, creativity, or modification beyond the scope. 2. Retrace the original specification to identify specific paragraphs and examples supporting the modification, and create a modification comparison table. 3. Adopt the minimum necessary modifications, prioritizing the incorporation of technical features from dependent claims into independent claims to overcome the defects, rather than generalizing and expanding them. 4. For those that cannot be resolved within the original scope, replace the modifications with reasoned statements or evaluate filing a divisional application for a separate layout. Throughout the process, retain the basis for the modifications and, if necessary, consult a professional agent to ensure the modifications are legal and maximize the possibility of obtaining a patent authorization.
