Golden Rule

In most countries — China, Europe, Japan, Brazil, South Korea — a single public disclosure before filing destroys patent novelty permanently. File first. Disclose second. Contact IP counsel at least 3 months before any international deadline falls due.

Why It Matters

International IP protection is the most time-sensitive decision in your IP strategy

Miss one deadline and you lose rights in that market permanently.

  • Stop competitors from copying your product, brand, or technology in export markets
  • Enter foreign markets with legally enforceable rights and customs recordals
  • Attract foreign investors, licensees, and strategic partners
  • Generate royalty income from overseas licensees and technology transfer
  • Block counterfeit goods at borders using registered IP rights
  • Build enterprise value and IP portfolio for international sale or joint venture

Step 1

Identify What You Are Protecting

Before filing internationally, confirm which IP right applies to each asset you own.

Your Asset Type of International Protection
Brand Name / Slogan Trade Mark
Logo / Visual Identity Trade Mark
New Product or Technology Patent
Manufacturing Process Patent or Trade Secret
Product Shape or Appearance Registered Design
Software / Application Code Copyright and Patent in select countries
Creative Content / Manuals Copyright
Confidential Formula / Data Trade Secret plus NDA
Plant Variety Plant Variety Protection

Step 2

IP Identification Checklist

Tick every item that applies. Every tick is a potential international filing.

Brand and Trade Mark Assets

  • Brand name, product name, or company name used in foreign commerce
  • Logo, emblem, visual identity mark, or certification mark
  • Tagline, slogan, or advertising phrase with distinctiveness
  • Packaging shape, colour, or trade dress distinguishing your goods
  • Domain names and social media handles requiring protection in target markets

Patents and Technical Innovations

  • Novel product, device, or article of manufacture not yet publicly disclosed
  • Novel process, method, or manufacturing technique
  • Software with a technical effect (patentable in USA, EPO, China, Japan)
  • Improvement to an existing product or process not in the prior art

Designs

  • Unique visual appearance, shape, or ornamentation of a product
  • Packaging or label design with distinctive aesthetic features
  • User interface or icon design with commercial significance

Copyright and Confidential Information

  • Software code — automatic copyright in 181 Berne countries on creation
  • Research data, publications, manuals, or marketing content
  • Proprietary formula or know-how to be protected by trade secret and NDA

Step 3

International IP Health Check

Answer these honestly. Every “No” requires immediate action.

Deadlines and Priority

  • Have you identified your Indian home filing date and calculated all international deadlines?
  • Are you within 12 months of your Indian patent filing date?
  • Are you within 6 months of your Indian trade mark or design filing date?
  • Have you obtained Section 39 clearance before filing any patent outside India?

Freedom to Operate and Clearance

  • Has a clearance or availability search been conducted in each target country?
  • Has a freedom-to-operate analysis been completed for each target market?
  • Are you confident your product does not infringe third-party patents abroad?

Ownership and Documentation

  • Have all inventors signed an assignment deed in favour of the applicant?
  • Is the applicant entity confirmed for all target jurisdictions?
  • Have contractor and employee IP assignment agreements been executed?

Budget and Agent Readiness

  • Have you identified and instructed IP filing agents in each target country?
  • Has the budget for filing fees, translation, and agent costs been approved?
  • Is a deadline tracking system in place for all prosecution and renewals?

Step 4

The “Stop and Check” Tool

Before sharing your innovation or brand with any external party, run this check. Any item you cannot confirm means: stop — consult your IP counsel first.

Are you about to share with any of the following?

1Investors, venture capital firms, or angel investors
2Foreign distributors, agents, or export customers
3Manufacturers, contract manufacturers, or OEM partners abroad
4Consultants, advisors, or technical collaborators
5Trade fairs, exhibitions, conferences, or press events
6Potential joint venture or licensing partners

Before sharing, confirm the following

  • A patent application has been filed in India establishing a priority date
  • An NDA has been signed by the recipient before any disclosure
  • The disclosure will not affect patent rights in any target country
  • A trade mark application has been filed before the mark is used publicly abroad
Critical — Novelty Rules By Country

Absolute Novelty vs. Grace Periods

China, Japan, Germany, France, Brazil, South Korea: Absolute novelty — any disclosure before filing permanently destroys patent rights. No exceptions.
USA and Canada: 12-month grace period for inventor’s own disclosures only.
India: 12-month grace period for exhibitions or government publications only.

Step 5

Your International Deadline Calendar

All deadlines run from your earliest Indian (home country) filing date.

IP Right Route / Office Deadline from Priority Date
Patent PCT Route 12 months from Indian filing
Patent PCT National Phase 30 months from Indian filing
Patent Paris — Direct Filing 12 months from Indian filing
Patent USA (USPTO) 12m Paris or 30m PCT
Patent Europe (EPO) 12m Paris or 31m PCT
Patent China (CNIPA) 30 months from Indian filing
Patent Japan (JPO) 30 months from Indian filing
Patent South Korea (KIPO) 30 months from Indian filing
Patent Australia 12m Paris or 31m PCT
Trade Mark Madrid System 6 months from Indian TM filing
Trade Mark EUIPO (EU, 27 states) 6 months from Indian TM filing
Trade Mark UK (UKIPO) 6 months from Indian TM filing
Trade Mark Direct — Any Country 6 months priority or any time
Design Hague System (WIPO) 6 months from Indian design filing
Design EU Design (EUIPO) 6 months from Indian design filing
Design USA Design Patent 6 months from Indian design filing
Copyright All Berne Countries Automatic — no deadline
Important

Deadlines Are Non-Extendable

Missing the 12-month Paris or PCT deadline for patents permanently forecloses international rights in most countries. Missing the 6-month trade mark priority period means filing without priority, which may allow intervening third-party registrations to block your mark.

Step 8

International IP Protection Roadmap

Follow these four stages in sequence. Each stage builds on the previous one.

1

Preparation — Before Filing

  • Document your invention, brand, or design with dated internal records
  • Execute NDAs before sharing with any external party in any country
  • Conduct prior art search and FTO analysis in all target countries
  • Confirm Section 39 clearance before filing any patent outside India
  • Identify and instruct foreign IP agents; execute Powers of Attorney
2

File and Establish Priority

  • File Indian application to establish the priority date
  • File PCT application within 12 months (multi-country patent strategy)
  • File Madrid System application within 6 months (trade marks)
  • File Hague application within 6 months (designs)
  • Obtain certified copy of Indian priority application
3

National Phase and Prosecution

  • Enter national phase in each target country within the applicable deadline
  • Commission certified translations for all required jurisdictions
  • Respond to office actions and examination reports in each country
  • Pay all national phase entry fees and local agent fees
  • Monitor application status across all jurisdictions
4

Post-Grant and Portfolio Management

  • Pay annual renewal and maintenance fees in every registered country
  • Monitor for infringement; file oppositions or cancellations where needed
  • Expand filings to new markets as the business grows
  • Negotiate licensing and royalty arrangements with foreign partners
  • Conduct IP valuation for investment, acquisition, or balance sheet purposes

Step 9

Documents You Must Have Ready

Gather these before your first international filing. Missing any one can delay or invalidate.

For All International Filings

  • Certified copy of Indian priority application (required for Paris Convention and PCT)
  • Power of Attorney in favour of foreign filing agent — notarised or apostilled
  • Signed assignment deed from all inventors to the applicant
  • Proof of entity type — certificate of incorporation, MSME or startup certificate
  • Priority document with certified English translation if application is in Hindi

For Patents

  • Complete specification with all claims, drawings, and abstract in English
  • Declaration of inventorship (required by USPTO, JPO, KIPO, and others)
  • Sequence listing in WIPO ST.26 format (biotech and pharma only)
  • Certified translations into Chinese, Japanese, Korean, Arabic as required
  • Information Disclosure Statement for USPTO — list all known prior art

For Trade Marks

  • Mark representation in the required format and resolution for each office
  • List of goods and services in International Nice Classification format
  • Proof of first use in commerce where required (e.g. USPTO)
  • Specimen of the mark in actual use for USPTO filings

For Designs

  • High-quality drawings or photographs from all required angles
  • Brief description of the article to which the design is applied
  • Statement of novelty identifying the features that are new

Step 10

Common Mistakes to Avoid

  • Filing internationally only after the product launch — priority is then lost in most countries
  • Disclosing the invention at a trade fair or in a publication before filing a patent application
  • Missing the 12-month PCT or Paris deadline — rights in those countries are permanently forfeited
  • Filing in the wrong entity name — causing ownership disputes across jurisdictions
  • Ignoring translation requirements until after the filing deadline has passed
  • Assuming US copyright or trade mark protection extends to all other countries
  • Not obtaining Section 39 clearance before filing an Indian resident’s patent abroad
  • Filing a Madrid trade mark application without checking availability in all designated countries
  • Failing to pay annual renewal fees — rights lapse silently, often without any reminder
  • Sharing innovations with foreign manufacturers without an NDA or IP assignment agreement

FAQ

Frequently Asked Questions

What is the PCT and why does it matter?
The Patent Cooperation Treaty lets you file a single international application that preserves your right to seek patent protection in 150+ member countries, giving you up to 30 months from your Indian filing date to decide which countries to enter.
What happens if I miss the 12-month PCT deadline?
You permanently lose the ability to claim priority from your Indian filing in most countries — you would need to file a fresh application, and any public disclosure in the meantime could destroy novelty entirely.
Do I need Section 39 clearance before filing abroad?
Yes, if you’re an Indian resident. You must either wait 6 weeks after your Indian patent filing or obtain prior permission from the Indian Patent Office before filing the same invention abroad — skipping this is a criminal offence under Indian law.
Does copyright need to be filed in every country separately?
No. Copyright arises automatically on creation in all 181 Berne Convention countries. Formal registration, such as with the US Copyright Office, isn’t required for protection but can aid enforcement.
Is the Madrid System the best route for trade marks?
It’s often the most cost-efficient way to cover 130+ countries through one application, but availability and enforceability should still be checked in each designated country before filing, since a Madrid mark can be refused locally even after international registration.
