Strategy and routing call A patent professional reviews your invention and target markets. We recommend a Receiving Office and an International Searching Authority, then map the national-phase countries you may want to enter later. 2 ### Draft and review We prepare the PCT specification, claims, and drawings to WIPO standards and send them for your review. Nothing is filed until you approve the application. 3 ### File through WIPO ePCT We file the international application via WIPO ePCT through your chosen Receiving Office, confirm the PCT application number, and docket every downstream deadline from filing day. What it costs ## Flat professional fee, quoted up front PCT International Application starts from $1,499. Your PCT filing is a flat professional fee, confirmed before any work begins and based on your chosen Receiving Office and ISA. WIPO international fees and ISA search fees are passed through at cost. National-phase entry into each country you later choose uses that country's own filing flow, quoted separately. What's included - International filing strategy: PCT, Paris Convention, or direct national routes - Receiving Office and International Searching Authority selection memo - Full PCT specification and claims, drafted to satisfy EPO Article 84 - WIPO ePCT filing through your chosen Receiving Office - Monitoring of the International Search Report and Written Opinion - Optional Chapter II International Preliminary Examination - Deadline tracking through national-phase entry Strategy and PCT routing Flat fee PCT drafting and WIPO filing Quoted on confirmation WIPO international fees Pass-through at cost WIPO international fees and ISA search fees are pass-through at cost. National-phase entry into each chosen country uses that country's own filing flow and is quoted separately. Get started ### Start a PCT application Tell us about your invention and target markets. A patent professional responds within one business day with a recommended PCT routing strategy and a national-phase country shortlist. No payment required Reply within 1 business day A GTC attorney reviews it & sends a flat-fee quote. 1. 01 Brand details 2. 02 More details 3. 03 Your details The PCT preserves your filing rights but does not grant a patent. Each target country still examines and decides the application on its own. Brand details 1 What is your invention called?\* A short descriptive title; a working name is fine. 2 Do you already have an earlier patent application to claim priority from?\* A PCT can claim priority from an application you filed in the last 12 months, carrying its early date worldwide. If you have one we claim it; if not, the PCT becomes your first filing. 3 Which receiving office should we file through?\* A PCT is one international application. Pick the receiving office (usually your home country or WIPO's International Bureau). You choose the specific countries later, at "national phase" — within about 30 months of your priority date. 4 What does the invention do? A paragraph on what it is and how it works helps us scope. 5 What is the technology field? Helps us route to the right patent attorney. BackNext Why GTC ## Why applicants route their PCT filing through GTC. Legal team GTC's patent team Patent counsel Attorney-led prosecution ### One filing, broad reach A single PCT application preserves your filing rights across the major patent jurisdictions. You file once now and decide where to commit national-phase spend later. ### Every deadline docketed Missing the national-phase deadline is generally fatal, and extensions are limited. We track international publication, the optional Chapter II demand, and national-phase entry from the day you file. ### Considered ISA selection Your International Searching Authority affects search quality, downstream examination, and cost. We recommend an ISA based on your target markets and budget rather than a default. ### One point of contact We coordinate national-phase entries across the major jurisdictions through one team, so you are not negotiating a separate engagement in each country. Your Customer Success Team ## A dedicated team that owns your matter from start to finish. Every GTC client gets a dedicated Account Manager and a Senior Account Manager who learn your business and stay with you from first email to final filing. They are named people who pick up the phone and already know your matter, so every step moves forward without delay. ### Your Account Manager Your day-to-day point of contact, who coordinates every matter, keeps things moving, and already knows your file. They have your full history, so you start every conversation where the last one left off. ### Your Senior Account Manager Senior oversight on strategy and escalations, stepping in as your needs grow, so every important detail stays on track. A named person, on email or a call, at every step. ![Your dedicated GTC Customer Success Team](/assets/m-onboarding-bright-welcome-C-heDolY.jpg) How we compare ## What a GTC PCT filing includes What you get GTC Online filing services Doing it yourself Written ISA selection memo for your markets National-phase country shortlist and cost forecast Specification drafted to satisfy EPO Article 84 Deadline docketing through national-phase entry One coordinated team for later national-phase entries WIPO ePCT filing through your Receiving Office Written ISA selection memo for your markets GTC Online filing services Doing it yourself National-phase country shortlist and cost forecast GTC Online filing services Doing it yourself Specification drafted to satisfy EPO Article 84 GTC Online filing services Doing it yourself Deadline docketing through national-phase entry GTC Online filing services Doing it yourself One coordinated team for later national-phase entries GTC Online filing services Doing it yourself WIPO ePCT filing through your Receiving Office GTC Online filing services Doing it yourself The timeline ## The PCT timeline at a glance Each date below is measured from your earliest priority date.
