Convention Application Filing Cost in India: Complete Guide to Paris Convention Patent Fees 2025
Everything you need to know about convention route patent filing costs, deadlines, and strategic considerations for India
If you've already filed a patent application in your home country and want to expand protection to India, the convention application route under the Paris Convention offers a direct path—but it comes with strict deadlines and specific cost implications that many inventors underestimate.
Unlike PCT applications that give you 30-31 months to decide, convention applications must be filed within 12 months of your earliest priority date. This compressed timeline makes understanding the exact convention application cost in India crucial for timely decision-making and budget planning.
After helping hundreds of inventors navigate both PCT and convention routes, I can tell you that while convention applications offer certain advantages, the cost structure is distinctly different and requires careful analysis to determine the most economical path for your specific situation.
Convention Application Cost Breakdown: What You're Really Paying For
The cost of convention application filing in India involves several components that differ significantly from regular patent applications due to the priority claim requirements and specific procedural elements.
Essential Cost Components (Updated 2025)
| Fee Component | Individual/Small Entity | Large Entity | When Due |
|---|---|---|---|
| Patent Application Filing | ₹1,600 | ₹8,000 | At filing |
| Priority Claim (per country) | ₹2,400 | ₹12,000 | At filing |
| Extra Claims (over 10) | ₹320 each | ₹1,600 each | At filing |
| Extra Pages (over 30) | ₹160 each | ₹800 each | At filing |
| Professional Drafting & Filing | ₹35,000 | ₹35,000 | At filing |
Translation costs for non-English applications can range from ₹15,000 to ₹50,000 depending on document complexity and technical terminology.
Convention vs PCT Route: The Cost and Timeline Reality
Understanding when to choose the convention application filing cost route versus PCT requires comparing both immediate and long-term financial implications.
Convention Application Route
- Must file within 12 months
- Direct filing in India: ₹38,600-₹65,000
- No international search report
- Faster to market (if grant succeeds)
- Priority claim fees: ₹2,400-₹12,000 per country
- Limited time for market validation
PCT National Phase Route
- Can file up to 30-31 months
- National phase in India: ₹22,100-₹28,500
- International search report included
- More time for business decisions
- Prior PCT costs: $1,500-$4,000
- Extended market validation period
The key insight: While convention applications have lower initial Indian filing costs, PCT provides better overall value when you consider the international search report and extended decision-making time.
The 12-Month Deadline: Cost Implications and Strategic Planning
The most critical aspect of convention application cost planning is the unforgiving 12-month deadline. Missing this deadline means losing priority rights permanently—no extensions, no appeals, no second chances.
First Filing (Home Country)
Original patent application filed. 12-month priority clock starts ticking.
Planning & Preparation
Market analysis, budget planning, priority document preparation. Cost: ₹0-₹20,000 (if search needed)
Convention Filing Deadline
Must file in India by this date. Cost: ₹38,600-₹65,000 depending on specifications
Examination Request Window
Request examination within 31 months of filing. Cost: ₹34,000-₹50,000
Hidden Cost Variables That Impact Your Budget
Beyond the standard convention patent filing fees India, several variables can significantly impact your total investment:
Priority Document Costs
₹2,000-₹15,000 per priority country depending on source country fees and legalization requirements
Translation Requirements
₹15,000-₹50,000 for complex technical documents from non-English countries
Claim Optimization
₹5,000-₹15,000 additional for adapting claims to Indian patent landscape
Expedited Processing
₹8,000-₹60,000 additional for accelerated examination depending on entity type
Strategic Cost Optimization for Convention Applications
Smart inventors use several strategies to optimize their convention application filing cost in India while maintaining strong patent protection:
1. Entity Status Optimization
- Verify small entity qualification carefully
- Individual inventors save 80% on government fees
- Startups with DPIIT registration qualify
- Improper classification costs ₹16,000+ extra
2. Priority Claim Management
- Each priority country costs ₹2,400-₹12,000
- Consolidate multiple priorities where possible
- Evaluate whether all priorities add value
- Consider partial priority claiming
3. Specification Optimization
- Minimize pages over 30 (₹160-₹800 each)
- Optimize claim count over 10 (₹320-₹1,600 each)
- Adapt international drafting for Indian requirements
- Focus on commercially relevant embodiments

When Convention Route Makes Financial Sense
The convention application route cost analysis isn't just about immediate expenses—it's about strategic positioning and long-term value creation. Here's when it typically makes sense:
Fast Market Entry
When you need patent protection quickly for licensing or manufacturing in India
Proven Technology
When your invention is already validated and you're confident about Indian market potential
Cost Sensitivity
When you want to avoid PCT filing costs and prefer country-specific decisions
Limited Geographic Scope
When India is one of only a few target countries for patent protection
Key Decision Framework: If your total target countries are fewer than 5 and include India, convention route often proves more economical than PCT. For broader international protection, PCT provides better value despite higher upfront costs.
Frequently Asked Questions About Convention Application Costs
Q: What happens if I miss the 12-month convention deadline?
A: Unfortunately, there's no grace period for convention applications. Missing the 12-month deadline means permanently losing priority rights from your original application. You can still file a regular patent application, but you'll lose the priority date advantage, potentially affecting novelty against intervening prior art.
Q: Can I claim priority from multiple countries in one convention application?
A: Yes, but each priority claim requires separate government fees (₹2,400-₹12,000 per country). You must also provide certified copies of priority documents for each country, which can add ₹2,000-₹15,000 per priority depending on source country requirements.
Q: How does entity classification work for foreign applicants?
A: Foreign individuals qualify for small entity status automatically. Foreign companies qualify as small entities only if they meet specific criteria (typically small companies or startups). Large foreign corporations pay large entity fees. Misclassification can result in significant additional costs later.
Q: Are translation costs really necessary for English-language applications?
A: If your priority application was filed in English, you typically don't need translation. However, you may need certified copies with official authentication, which can cost ₹2,000-₹5,000. For non-English applications, professional technical translation is mandatory and ranges from ₹15,000-₹50,000.
Q: What's the difference in examination costs between convention and regular applications?
A: Examination costs are identical (₹4,000-₹20,000 government fees + ₹30,000 professional fees). However, convention applications may face additional scrutiny regarding priority claims and unity of invention, potentially leading to more complex prosecution and higher response costs.
