Practical answers before starting a U.S. patent matter.
Use these questions to narrow filing route, fee expectations, provisional limits, government fees, and cross-border fit.
How much does a U.S. patent application cost?
ZYL offers defined-scope flat-fee patent services. Provisional applications start from $599, design applications from $850, and standard utility applications from $3,800.
Are USPTO government fees included?
No. USPTO official fees are passed through separately and depend on entity status, application type, claim count, pages, and procedural events.
Is a provisional patent application enough?
It may fit early priority-date needs, but it is not a substitute for a fully developed non-provisional application. The right route depends on the invention and business objective.
Do you guarantee that my patent will be granted?
No. No responsible patent professional can guarantee allowance. ZYL prepares and files professional applications and helps position the case for examination.
Do you use AI or technology tools?
ZYL may use structured workflows and technology tools to improve efficiency, but claim strategy, scope decisions, review, and filing judgment remain practitioner-led.
Can Chinese applicants file U.S. patents through ZYL?
Yes. ZYL supports PCT U.S. national phase entry, Paris Convention filings, Chinese-language disclosure coordination, translation issue spotting, and U.S. filing formalities.
