Chapter 5: Examination Response Strategies

5.1 Types of Examination Opinions

During substantive examination, CNIPA examiners may issue examination opinions (Notification of Examination Opinion) raising objections under the Patent Law. Common objections include: lack of novelty (Article 22), lack of inventiveness (Article 22), lack of practical applicability (Article 22), insufficient disclosure (Article 26), and unsupported claims (Article 26).

5.2 Response Strategies

The response period for a first examination opinion is 4 months from the date of receipt (with a possible 2-month extension upon request and payment of a fee). Response strategies include: amending claims to overcome cited prior art, arguing the differences between the invention and prior art, submitting experimental data to demonstrate technical effects, and requesting an interview with the examiner.

5.2.1 Inventiveness Arguments

The 2025 Patent Examination Guidelines revision introduced updated standards for inventiveness assessment, particularly for AI and computer-implemented inventions. Examiners now apply a three-step approach: (1) determine the closest prior art, (2) identify distinguishing features and the technical problem actually solved, and (3) assess whether the invention would have been obvious to a person skilled in the art.

5.2.2 Amendment Strategies

Claim amendments must not exceed the scope of the original disclosure. Amendments may include: merging dependent claims into independent claims, adding technical features from the specification, and narrowing claim scope. Applicants should carefully balance the need to overcome objections with the desire to maintain broad protection.

5.3 Final Rejection and Further Options

If the examiner maintains a rejection after response, the applicant may file a request for reexamination with the Patent Reexamination Board within 3 months of receiving the rejection decision. Alternatively, the applicant may file a divisional application or abandon the application.

While standard examination follows its regular timeline, certain situations may warrant accelerated processing. CNIPA offers several programs to expedite examination, which we explore in the next chapter.

Chapter 6: Accelerated Examination Programs

6.1 Priority Examination (Youxian Shencha)

CNIPA offers a priority examination program for invention patents in specific technical fields, including: energy-saving and environmental protection, new generation information technology, biotechnology, high-end equipment manufacturing, new energy, new materials, and integrated circuits. The target processing time is within 12 months from the date of approval.

6.1.1 Eligibility Requirements

To qualify for priority examination, the application must involve a significant technical contribution in one of the designated fields. The applicant must submit a request for priority examination together with supporting evidence demonstrating the technical significance and commercial value of the invention.

6.1.2 Processing Timeline

Under the priority examination program, the average examination cycle is significantly reduced compared to the standard 15.5 months. Most cases receive a first examination opinion within 3-5 months, with final disposition typically within 12 months.

6.2 Patent Prosecution Highway (PPH)

China participates in the Global PPH and PCT PPH programs. If an applicant receives a positive examination result from an Office of Earlier Examination (OEE), they may request accelerated examination at CNIPA as the Office of Later Examination (OLE). The PPH program can significantly reduce examination time and improve grant rates.

6.3 Preliminary Examination Acceleration for Utility Models

Utility models already benefit from a relatively fast preliminary examination process (6-12 months). For urgent cases, applicants may request accelerated preliminary examination, which can reduce the timeline to 2-3 months in certain circumstances.

When examination efforts do not yield the desired outcome, applicants have formal recourse through reexamination and invalidation procedures. These administrative remedies provide important checks on the examination process and are essential tools in patent portfolio management.
