Large entityImportant: unlike Chinese practice, U.S. claim rules and fees depend on claim type and count, and claim dependencies may need restructuring. 1. For an application based on a Chinese patent, including a priority claim, dependent-claim references must be separated before Chinese-to-English translation. 2. If final English documents are supplied, all referenced dependent claims should be separated before filing. No fee applies if the client does this; separation by our attorney costs CNY 200–500. 3. If restructuring produces more than 20 claims, the applicable official excess-claim fees must be paid; no pre-filing service fee applies. 4. If the USPTO issues a Notice to File Missing Parts requiring excess-claim fees, payment must be made promptly. Official fees are charged as incurred and the attorney fee is USD 80. Late payment may incur a revival fee; non-payment causes abandonment, and official and service fees are non-refundable.

Notes

1. The USPTO generally issues the filing receipt within 5–7 business days, excluding translation of the finalized documents, and the filing acceptance notice within 1–4 weeks. Filing to grant takes 2–3 years normally or 6–12 months with acceleration.

2. Entity status should be declared accurately. Any official-fee shortfall should be paid promptly; late payment may incur reinstatement, and non-payment causes abandonment with no refund of official or service fees.

3. Certificate issuance generally takes two months. Since 18 April 2023, only electronic certificates have been issued. The maximum term is 20 years.

4. Track One timing depends on USPTO workload and is not fixed. Accelerated cases receive priority over earlier non-accelerated filings but remain queued with other accelerated cases.

5. All timeframes are subject to the authority’s actual examination progress; we make no guarantee regarding processing times.
