PCT Patent Application Services in India
Keep Your International Patent Options Open While You Decide Where Protection Matters Most
A PCT patent application is the most strategically efficient way to protect an invention internationally — using a single filing under the Patent Cooperation Treaty to keep patent options open in more than 150 countries, while you take up to 18 months to decide which national markets truly matter for your business.
For Indian applicants, filing a PCT application through WIPO gives you international filing date priority, a standardized international search report, and the flexibility to enter national or regional patent phases selectively — without committing to expensive multi-country filings upfront.
Novel Patent Services helps inventors, startups, SMBs, businesses, and enterprises in India prepare and file PCT patent applications with structured support for PCT strategy, application preparation, national phase planning, and long-term international IP portfolio decisions.

What Is a PCT Patent Application?
A PCT patent application is an international patent filing made under the Patent Cooperation Treaty (PCT) — an international agreement administered by WIPO (World Intellectual Property Organization) that allows inventors and businesses to seek patent protection in more than 150 member countries through a single, centralized application process.
For Indian applicants, a PCT application can be filed through the Indian Patent Office (which acts as a Receiving Office) or directly through WIPO. The application establishes an international filing date, triggers an International Search Report (ISR) that assesses patentability, and gives the applicant up to 30 months from the earliest priority date to decide which national or regional patent offices to enter — without losing international protection options.
A PCT application does not automatically grant patent protection in every country. At the end of the international phase, you enter the national or regional phase in only the specific countries or regions you choose — allowing you to make targeted, budget-aware decisions about where your invention has real commercial value.
Key Questions About PCT Filing for Indian Applicants
- Should I protect my invention internationally, and is PCT the right route?
- Which countries matter most for my invention's commercial and business goals?
- How do I keep foreign filing options open without committing to multi-country costs upfront?
- How should I plan national phase entry across different jurisdictions?
- How does PCT filing connect with licensing, fundraising, or global expansion plans?
- What happens during the international phase after a PCT application is filed?
A PCT patent application gives you up to 30 months from your priority date to decide exactly which countries to enter — protecting your invention globally while you evaluate markets, secure funding, and build the commercial case for each jurisdiction.
Who Should File a PCT Patent Application from India?
Inventors
Want to protect an invention internationally and keep foreign filing options open without immediately committing to expensive multi-country filings.
Startups
Preparing for global expansion, international fundraising, cross-border licensing, or international market entry. A PCT filing supports investor confidence and keeps IP options open during growth stages.
SMBs
Protecting inventions across multiple markets or planning international commercialization. PCT provides a cost-effective route to international protection with strategic flexibility.
Businesses
Need international patent filing support aligned with commercial goals, market expansion timelines, and IP portfolio strategy.
Enterprises
Managing global patent filing strategies across product lines, national phase planning across multiple jurisdictions, and long-term patent portfolio decisions.
Indian Applicants
Looking for structured PCT application filing support in India, national phase planning across key markets and international IP strategy aligned with Indian business goals.
Why PCT Filing Matters Now
Most inventions with global commercial potential are never fully protected internationally — not because the inventors didn’t want to protect them, but because they waited too long, chose the wrong filing route, or didn’t realize they had a strict 12-month window from their Indian priority date to file internationally. If you’ve already filed a patent application in India and you haven’t filed a PCT application within 12 months of that date, your international filing window closes permanently. No extension. No exceptions.
The PCT route doesn’t just protect your invention — it gives you 30 months of strategic flexibility to decide where protection matters before you spend money entering national phases in individual countries. That 30-month window is the difference between a reactive IP strategy and a business-aligned global protection plan.
WITHOUT a Clear PCT Filing Strategy
- Your 12-month international filing window closes permanently after your Indian priority date
- Missed foreign filing opportunities in key commercial markets — USA, Europe, China, Japan
- Confusion around PCT application deadlines, national phase entry dates, and 30-month windows
- Weak coordination between your Indian filing and international protection strategy
- Poor alignment between patent protection and actual business markets
- Higher long-term filing costs due to poorly timed or redundant national phase entries
WITH a Structured PCT Filing Strategy
- International filing options kept open across 150+ countries from a single application
- 30 months of strategic flexibility to evaluate markets before committing to national phase costs
- International Search Report (ISR) gives early patentability feedback before national phase investment
- Coordinated alignment between Indian filing, PCT filing, and national phase planning
- Licensing, fundraising, and global expansion plans supported by an active international application
- Long-term IP portfolio built with clear country selection, budget planning, and commercial alignment
"The goal of PCT filing is not to protect your invention everywhere. The goal is to protect it in the countries where your invention has real, defensible commercial value — and to keep every other option open while you decide."

Frequently Asked Questions
What is a PCT patent application?
A PCT patent application is an international patent application filed under the Patent Cooperation Treaty (PCT) — an international agreement administered by WIPO (the World Intellectual Property Organization). A PCT application allows inventors and businesses to seek patent protection in more than 150 member countries through a single, centralized filing process. It does not automatically grant patent protection in every country, but it keeps international patent options open while you evaluate markets, commercial goals, and national phase strategy.
How does PCT filing work for Indian applicants?
Indian applicants can file a PCT application through the Indian Patent Office (which acts as a PCT Receiving Office) or directly through WIPO. To be eligible, at least one applicant must be a national or resident of a PCT member state — India is a member. After filing, WIPO issues an international filing date and assigns an International Searching Authority (ISA) to produce an International Search Report (ISR). Indian applicants typically have the Indian Patent Office or the European Patent Office assigned as ISA. The ISR assesses patentability and is a valuable tool for evaluating the invention’s strength before committing to national phase entry costs.
How many countries does a PCT application cover?
A PCT application can be used to seek patent protection in more than 150 countries that are members of the Patent Cooperation Treaty, including major markets such as the USA, European Union countries (via the European Patent Office), China, Japan, South Korea, Canada, Australia, and many others. A single PCT application keeps all these options open during the international phase — you only commit to specific countries when you enter the national or regional phase.
Not always, but they are often important when they help explain the invention more clearly and completely.
How long does a PCT application keep international options open?
A PCT application generally gives you up to 30 months from your earliest priority date (usually the filing date of your Indian patent application) to decide which national or regional patent offices to enter. This 30-month window allows you to evaluate markets, assess the International Search Report, secure funding or licensing deals, and make strategic decisions about which countries justify the cost of national phase entry — without losing your international priority position.
What is the deadline to file a PCT application from India?
If you have already filed a patent application in India, you must file your PCT application within 12 months of your Indian filing date to claim priority under the Paris Convention. If you miss this 12-month window, you can still file a PCT application, but you will not be able to claim the Indian priority date — meaning any public disclosures made after your Indian filing date could be cited against your PCT application. It is strongly advisable to file your PCT application within 12 months of your Indian application to preserve full priority benefits.
What is the difference between PCT filing and direct national filing?
Direct national filing (also called the Paris Convention route) means filing patent applications individually in each target country within 12 months of your priority application. This route is faster per country but requires earlier financial commitment and country-by-country strategy decisions. PCT filing allows you to make a single international application and delay national phase entry decisions for up to 30 months — giving you more time to evaluate markets, review the ISR, and plan strategically. PCT is generally preferred when you are targeting three or more countries, need more time for market evaluation, or want to reduce upfront filing costs.
What happens after a PCT application is filed?
After filing a PCT application, WIPO issues an international filing date and publishes the application approximately 18 months from the priority date. An International Searching Authority (ISA) prepares an International Search Report (ISR) and Written Opinion on patentability — typically within 16 months of the priority date or 9 months from the PCT filing date, whichever is later. You may optionally request an International Preliminary Examination for a further patentability assessment. During the national phase (typically entered at 30 months from priority), you file national or regional applications in your chosen jurisdictions and pay the relevant national fees.
How much does a PCT patent application cost from India?
The cost of a PCT patent application from India includes WIPO international filing fees (charged in Swiss francs, with reductions for applicants from developing countries including India), transmittal fee to the Indian Patent Office Receiving Office, search fee for the assigned International Searching Authority, and any professional preparation fees for the application. Indian applicants — particularly individuals, small entities, and startups — may qualify for fee reductions under WIPO’s fee schedule. National phase entry costs are additional and vary by jurisdiction. Novel Patent Services can provide a transparent cost breakdown based on your specific target countries and applicant type.
Can a startup or small business use PCT filing?
Yes, and PCT filing is often particularly valuable for startups and small businesses with global ambitions. A PCT application allows early-stage companies to secure international priority and keep global filing options open while they focus on product development, fundraising, and market validation — without immediately spending on multi-country national filings. An active PCT application can also be a meaningful signal to investors and partners that the startup has taken concrete steps to protect its technology internationally. WIPO offers reduced fees for qualifying small entities and micro entities, reducing upfront PCT costs.
