The practice behind the desk
A focused desk.
An accountable team.
EastFiling is a streamlined point of contact for trademark and design filing inquiries across East Asia.
Our operating practice
Supported by Zhiquan IP.
EastFiling is operated by Zhiquan IP, the established China IP practice behind this project. EastFiling is a service brand, not a separate law firm.
The Mainland China operating entity is 深圳市智圈知识产权代理事务所（普通合伙）. You can review the practice’s published verification information on its own website.

For Mainland China, inquiries are reviewed through Zhiquan IP. For Japan, South Korea, Hong Kong, Macau and Taiwan, local professional handling arrangements must be confirmed before instructions are accepted.
EastFiling does not claim to have offices or locally licensed teams in all six jurisdictions. The responsible provider and scope are confirmed for each matter.
Intentionally focused
Trademark first.
Design alongside.
Our website focuses on two filing services. This keeps the inquiry, scope review and quotation process clear for international firms and businesses.
Sending an inquiry does not create an engagement or trigger a filing. The team confirms the scope, responsible handling, documents and fees before accepting instructions.

Professional responsibility and payment
EastFiling is the service brand. Zhiquan IP contracts for and remains responsible for the agreed professional services. OpenPTO Co., Limited, Hong Kong, is the authorised collector and issuer of English commercial Invoices and Receipts.
Payment made under the Invoice instructions and actually received by OpenPTO satisfies the corresponding payment obligation to Zhiquan. Internal settlement does not require you to pay twice.
USD bank transfer and prepayment apply. An approved quotation normally remains valid for 14 calendar days; a new trademark Invoice normally falls due within three days of issue; earlier invoices and design matters retain their stated dates. Customer-reported transfers are checked against actual cleared funds.
For an authenticated matter with its private upload facility available, submit each requested file in the corresponding upload item. If that facility is unavailable, contact peterlin@eastfiling.com with the EastFiling reference to agree a secure alternative. Receipt, security checks, material review, your exact final-package approval, professional release and official filing evidence are separate records.
OpenPTO receives only the financial and limited identifying information needed for collection and records; it does not receive automatic access to the full technical file. Initial-stage archive does not end applicable notice and deadline obligations.
