Official fees are separate
USPTO fees vary by large/small/micro entity status, claims, pages, IDS volume, extensions, issue fees, and maintenance fees.

Predictable professional fees for U.S. patent work.
ZYL uses fixed-fee and scoped-fee packages where possible. USPTO official fees are passed through separately because they depend on entity status, claim count, page count, deadlines, and procedural events.

Pricing FAQ
Why not include USPTO fees in the package?
Official fees depend on facts outside the professional-service scope, including entity status, claim count, filing route, page count, and procedural events.
What may increase the professional fee?
Multiple inventions, extensive embodiments, urgent deadlines, poor source materials, software eligibility issues, translation problems, and complex prosecution history can increase scope.
Can you provide a written quote?
Yes. After reviewing the invention disclosure or Office Action, we can provide a written scope and fee before formal engagement.
Do you offer a free first call?
No. We do not offer free phone consultations. Email a short description of your invention and timing to patent@zyllaw.com; we review it in writing, recommend the filing route and package, and send a written flat-fee quote. A call is scheduled only when the matter genuinely needs one.
