Common questions

Does a foreign-domiciled patent applicant need U.S. counsel?

Yes. For papers received on or after July 20, 2026, the USPTO generally requires foreign-domiciled patent applicants and owners to be represented by a USPTO-registered patent practitioner, regardless of when the application was filed.

Can you coordinate with foreign counsel?

Yes. We regularly work with overseas clients and can coordinate with foreign patent firms or in-house IP teams.

Why does U.S. claim style matter?

U.S. examination, eligibility, written description, and claim-fee rules can differ substantially from other jurisdictions.

Do you provide bilingual support?

Yes. ZYL can support bilingual patent communication and cross-border project coordination.

Can you estimate the total budget?

We provide professional-fee scope and expected USPTO official-fee estimates before filing when materials are available.
