Choose a patent type and jurisdiction to get an itemized estimate of official and agent fees; the specifics are confirmed by a licensed attorney / agent.
A USPTO final rule requires applicants and owners domiciled outside the US to be represented by a US-registered patent attorney or agent, covering utility, design, and all subsequent filings. Self-filing is no longer available.

We don't promise an examination outcome — and that honesty is part of our professionalism
Figures come from official fee schedules and market references — not a final quote.
Most small applicants qualify as a small entity (40% of official fees); micro-entity criteria are stricter.
Review & File = you draft with our AI tool; Guaranteed includes a refund-if-not-granted clause (per engagement agreement).
The service fee buys full-chain representation by a licensed attorney / an agent registered in the target jurisdiction to pursue patent protection — including:
Exact scope is set by the formal engagement contract.
You draft, the firm sees it through
End-to-end representation · unlimited office action responses
Everything in Full Service + full agency-fee refund if not granted (per engagement agreement)
If finally not granted, the full agency service fee is refunded (official and third-party fees excluded); exact terms per the engagement agreement
We do not promise examination outcomes — the refund is a fee arrangement, not a guarantee of grant (terms per engagement agreement)
Both tiers include full-chain representation and unlimited OA rounds; the enhanced package adds deeper services on top.

Service tiers apply to invention patents only; utility models and designs are single-tier.
Service fee · reference price · official fees extra · Service fees vary with case complexity and are reference prices; the formal engagement contract governs.

An invention or utility model completed in China usually requires a CNIPA foreign-filing secrecy review first; designs are exempt.
The Paris route generally requires filing within 12 months of priority; the PCT route extends national-phase entry to 30 months, suiting multi-country plans.
AI handles the preliminary assessment and cost estimate; formal drafting, prosecution, and filing are handled and signed by a licensed attorney / an agent registered in the target jurisdiction.
The total is official fees plus agent service fees, varying by target jurisdiction (China / US / Europe), patent type, entity size, and claim count — the three differ substantially in magnitude. Use the calculator above for an instant estimate for your situation; official fees follow the current CNIPA / USPTO / EPO schedules.
A USPTO final rule requires applicants and owners domiciled outside the US to be represented by a US-registered patent attorney or agent, for filing and all subsequent papers. Applicants from China therefore must work through a US-registered practitioner.
A design patent protects a product's appearance, examines faster, and has no maintenance fees — common for e-commerce anti-copying; a utility patent protects the technical solution with stronger but slower, costlier protection. The choice depends on the product and can be combined.
An invention or utility model completed in China usually needs a CNIPA foreign-filing secrecy review first; filing abroad without it may affect the validity of the corresponding Chinese patent. Designs are exempt.
For a few clearly-chosen countries, the Paris route (file within 12 months of priority) is more direct; for multi-country plans or when more time is needed, the PCT route (national-phase entry within 30 months) is more flexible.
The platform uses AI for a preliminary assessment and cost estimate to help you gauge the right type and route; formal drafting, office-action responses, and filing are handled and signed by a licensed attorney / an agent registered in the target jurisdiction. Assessment results are informational only and are not legal advice or a promise of grant.
It's a real investment. What you're paying for is full representation by a licensed attorney / an agent registered in the target jurisdiction to pursue enforceable patent protection. On a tighter budget, a design patent is faster and lower-cost as an entry point — an advisor can compare options for your specific product.
No firm can promise the outcome of an individual case — it depends on the novelty and inventiveness of the technology itself, not on who files it. What we can do is have a licensed attorney / an agent registered in the target jurisdiction involved throughout drafting and office-action responses, doing every controllable part well. Being honest about outcomes is a matter of professionalism for us.
A local firm is of course an option, but communication is a real cost — you speak Chinese and so does your advisor, so discussing the invention, explaining terminology, and syncing on progress all skip a translation layer. On the US and European side, locally registered agents handle the filing, with the same professional standing. Which route you pick comes down to how much you value communication efficiency versus other factors.
After the EPO grants a patent, the owner must validate it in each state of interest for it to take effect there. Germany, France, the UK, and Switzerland waive translation under the London Agreement, so the official validation fee is 0; Italy and Spain still require a full translation. This page's calculator gives a line-item estimate based on the states you select.
