In-Depth Guide: Patent Application — Invention (Form สป.01) (สป.01)

Patent Application — Invention (Form สป.01) is delivered under ILC's Thai Intellectual Property, Trademark and Patent Practice practice, combining MoJ-certified translation, MFA legalization, embassy liaison, and Thai government filing under one project manager. Every case is handled by a NAATI-accredited translator, a Thai Notarial Services Attorney, and a dedicated case coordinator.

Thailand is a Madrid Protocol contracting party (since 2017) and a Patent Cooperation Treaty (PCT) member, making it a strategic Asian filing hub for brand and technology owners. ILC prosecutes trademarks, service marks, collective marks, certification marks, and geographical indications under the Trademark Act B.E. 2534 (as amended 2016), and patents / petty patents / designs under the Patent Act B.E. 2522. Enforcement is delivered through the Central Intellectual Property and International Trade Court (CIPITC), Customs recordal against counterfeit imports, e-Commerce takedown filings, and Suppression Division criminal complaints. Trademark examination timelines shortened to ~18 months in 2024, and DIP now offers e-filing with instant certificates upon grant.

Why choose ILC for Patent Application — Invention (Form สป.01)

With more than 15 years of practice, ILC covers every embassy in Bangkok and both MFA offices (Chaengwattana and Chiang Mai). We operate a two-tier QA review and refund the service fee if a document is rejected due to a defect in our translation or certification — government fees and officer discretion excluded.

A working guide to Ip Trademark in Thailand

Ip Trademark has been the daily bread of our Bangkok office since 2004. Each matter is opened as a numbered case file that carries the same audit trail — intake note, translator sign-off, attorney jurat, and MFA/embassy stamps — from the first LINE message through to final courier hand-off. Every Ip Trademark matter is scoped by a senior specialist on LINE Official @NAATI or by email at ilc@thainotary.co.th before any file moves.

How the workflow runs end-to-end

Every deliverable ships with a scanned colour PDF archive alongside the physical original, so the client can lodge with foreign embassies, DHA ImmiAccount, or destination universities the same day the original is dispatched by DHL, FedEx, EMS, or Kerry.

Who this service is for

Individual applicants typically move from first LINE message to signed jurat in under 72 hours; corporate and cross-border matters are quoted on their own SLA depending on volume, destination, and required chain of legalization.

Coverage, fees, and turnaround

International return is handled by DHL Express, FedEx International Priority, or Thailand Post EMS depending on destination and client preference; each option carries a signed proof-of-delivery scan sent to the client's registered email once the pack is received abroad.

Quality assurance and confidentiality

For matters that go before Thai courts, translations are re-certified under the Ministry of Justice's court-listed translator register so the deliverable is admissible as a documentary exhibit under the Civil Procedure Code without a separate hearing on authenticity.

Start your Ip Trademark matter today

Reach ILC on LINE Official @NAATI, email ilc@thainotary.co.th, or phone 080-5578887. Office hours are Monday to Sunday, 08:30 to 20:00 Bangkok time. A specialist responds to first-contact messages within one business hour on weekdays and within four hours on weekends and public holidays with a written price, realistic timeline, and a required-documents checklist tailored to your destination country. There is no charge for the initial consultation, and no obligation to proceed after receiving the quote — ILCearns repeat business by delivering the first Ip Trademark matter cleanly and on time, not by locking clients into open-ended retainers.
