FAQ

Frequently Asked Questions

What flat-fee IP services does ZYL Law provide?
ZYL Law provides flat-fee U.S. patent, trademark, and copyright services: utility, provisional, and design patent filings; trademark applications and prosecution; copyright registrations; Office Action responses; TTAB proceedings; and e-commerce IP defense, including Amazon complaints, DMCA counter-notices, APEX evaluations, and Schedule A / TRO reviews.
How much does a U.S. trademark application cost?
ZYL Law's professional fee is $300 per class for an intent-to-use application and $350 per class for use-based or foreign-registration applications. The USPTO fee for most new applications is $350 per class and is billed separately.
How much does a U.S. patent application cost?
Professional fees start at $1,650 for a provisional application, $690 for a design patent application, and $3,800 for utility patent drafting. USPTO fees depend on entity size, claim count, and filing route and are itemized separately.
Are official filing fees included in flat-fee packages?
Usually not. ZYL professional fees and government fees are itemized separately. A limited number of expressly identified foreign-to-U.S. patent packages include specified USPTO fees; the written quote controls and lists every inclusion and exclusion.
Does a foreign company need a U.S. attorney or patent practitioner?
Generally yes. Foreign-domiciled trademark applicants and registrants must be represented by a U.S.-licensed attorney before the USPTO, and for papers received on or after July 20, 2026, foreign-domiciled patent applicants and owners generally must be represented by a USPTO-registered patent practitioner.
What should I do after receiving a USPTO Office Action?
Send us the Office Action promptly. The response period is usually three months, and extensions are available in many cases for a fee. Trademark Office Action responses are $250 to $600 and patent Office Action responses start at $690, quoted after we review the refusal.
My Amazon listing was removed for an IP complaint. Can you help?
Yes. We start with a $250 written triage of the complaint within two business days. DMCA counter-notices are $450, trademark complaint appeals are $600, and Amazon APEX patent evaluations start at $500, with the APEX deposit billed separately.
Can you also protect my IP in China?
Yes. Our team includes lawyers licensed in China and a holder of the PRC patent attorney qualification. We coordinate China patent, trademark, and copyright filings and enforcement in English; filings are submitted through a licensed Chinese agency we partner with, and fees are quoted per matter in writing.
Do I need a consultation before getting a quote?
No. Email a short description of your matter to ip@zyllaw.com (patents: patent@zyllaw.com). We confirm the scope, run a conflict check, and send a written flat-fee quote. A call is scheduled only when the matter genuinely needs one.
