Now picture yourself creating something amazing, an object, a process, or a brilliant idea. Now think about taking it to Bangladesh, a nation bursting at the seams. With over 160 million people and industries like textiles, pharmaceuticals, and technology thriving, it’s a goldmine for US inventors like you. Patent registration in Bangladesh, But here’s the kicker, without a patent, your idea’s fair game for anyone. Don’t worry, though. In this post, I will take you through a step-by-step guide on how to register a Patent in Bangladesh and get rich out of the invention you made your dreams. So here goes the interesting, simple, and informative all in one!
Abdul should immediately file a patent application for his solar-powered irrigation controller with Bangladesh’s Department of Patents, Designs and Trademarks (DPDT) under the Ministry of Industries to secure exclusive rights and prevent copying before market launch. This is where patent registration in Bangladesh transforms inventors into industry leaders.
At Zivadra, we’ve guided hundreds of Abdul-like visionaries through Bangladesh’s newly modernized patent landscape. The game-changer? The Patent Act 2023, effective February 27, 2025, replaces colonial-era rules with TRIPS-compliant protections.
Why Patent Registration in Bangladesh Just Became Your Competitive Superpower

Bangladesh’s Patent Revolution: Beyond the 16-Year Era
For decades, inventors struggled under the 1911 Patent Act’s 16-year protection cap. The Patent Act 2023 unleashes four critical upgrades:
- 20-year terms (up from 16 years), aligning with global standards
- Utility model patents for incremental innovations (8-year protection)
- Stricter infringement penalties, criminal charges for willful violations
- Digital enforcement tools, including Customs-led border seizures
Table: Bangladesh’s Patent Evolution – Old vs. New
Aspect | Pre-2025 System | 2023 Act (2025+) |
Term Length | 16 years | 20 years |
Examination Request | Not required | Mandatory (within 36 months) |
SME-Friendly Options | None | Utility model (8-year term) |
Restoration Window | Unclear | 2 years from lapse |
The Zivadra-Approved Patent Pathway: 3 Phases, 9 Steps
Phase 1: Preparation & Filing, Building Your Patent Fortress
Step 1: Patentability Triathlon
Your invention must clear three hurdles:
- Novelty: Zero global public disclosure pre-filing (e.g., Razib’s jute composite material wasn’t novel after his Tech Expo demo)
- Inventive Step: Non-obvious to experts (like Durdana’s AI-based flood prediction algorithm surpassing existing models)
- Industrial Applicability: Practical usability (tested by Zivadra’s feasibility matrix)
Step 2: Document Blitz
- Provisional spec: Quick filing to “stake your claim” (12-month clock starts!)
- Complete spec: Detailed diagrams, claims, and microbiome deposit certificates if applicable
- Priority documents: Certified translations if claiming Paris Convention priority
Step 3: DPDT Submission
File at Dhaka’s Department of Patents, Designs & Trademarks (DPDT) with:
- Power of Attorney (notarization NOT required—unlike trademarks!)
- Fee payment (page/claim-based)
Phase 2: Examination & Publication, The Patent Gauntlet
Step 4: Formalities Check
DPDT verifies documentation completeness.
Zivadra clients’ pre-audit docs to avoid 90% of deficiencies.
*Step 5: Pre-Grant Publication*
At 18 months, your application is published publicly. Pay extra for early publication if investors are circling.
Step 6: Opposition Round
Competitors have 6 months to challenge your patent. Zivadra’s 2024 data shows 70% of oppositions target pharmaceutical/agritech patents.
Step 7: Examination Showdown
- Request substantive examination within 36 months, or ABANDONMENT occurs
- Examiner assesses novelty/inventiveness using foreign patent data (must submit within 90 days if requested)
Phase 3: Grant & Monetization, Securing Your 20-Year Empire
Step 8: Patent Grant
After overcoming objections, pay the sealing fee for your Letters Patent certificate.
*Step 9: Post-Grand Vigilance*
- Annual renewals start from Year 6 (lapse = 2-year restoration window)
- Post-grant oppositions are possible for 24 months. Maintain detailed usage records!
Why Bangladesh? It’s a Hidden Gem for US Inventors!
So, why should you care about Bangladesh? Let’s break it down. This country’s on fire, economically speaking (though the humidity’s no picnic either!). It’s clocking over 6% GDP growth yearly, with a population of 160 million that’s young, eager, and increasingly able to spend. By 2030, the middle class could double, meaning millions more customers for your patented gadget or process.
Then there’s manufacturing. Bangladesh is a global textile titan, exporting $40 billion in apparel annually, second only to China. Labor costs are low, and the workforce is skilled, making it a dream spot to produce your invention. Picture this: Your patented lightweight, breathable fabric gets picked up by a Bangladeshi exporter. You’re saving them money, they’re making you money, everyone’s happy.
Location’s another perk. Bangladesh sits between India and Southeast Asia, with the Bay of Bengal as its front door. It’s part of the South Asian Free Trade Area (SAFTA), giving you a launchpad to nearby markets. As a Least Developed Country (LDC), it also gets IP flexibilities under treaties like TRIPS, which can ease your entry.
The legal system’s catching up, too. The 2023 Patent Act syncs Bangladesh with international norms, so your rights are solid. Enforcement’s not perfect (more on that later), but it’s improving. Take this real-world win: A US startup patented a solar-powered irrigation pump here. Now they’re licensing it to rural co-ops, cutting costs and boosting yields. That’s the Bangladesh edge.
Still not sold? Consider the cost advantage. Patenting here is dirt cheap compared to the US, hundreds, not thousands. Not to mention licensing deals or Joint ventures you create while keeping your IP safe with a patent. But it’s a calculated move with massive upside.
Utility Models: Bangladesh’s Shortcut for Incremental Innovators
For SMEs like Faria’s Khulna textile machinery workshop, utility model patents offer:
- Faster registration (no substantive examination)
- 8-year protection for upgrades (e.g., loom efficiency mods)
- 60% lower costs vs. standard patents

- Translation Time Bombs
Priority docs not translated? Rejections loom. Use DPDT-approved translators only. - Fee Amnesia
Annual renewals from Year 6 seem distant, until Year 7 when your patent lapses. We recommend annuity escrow accounts. - Foreign Application Oversharing
Disclosing unfavorable foreign reports? Strategize responses with patent attorneys. - Microorganism Mishaps
For biotech patents (like BARI’s flood-resistant rice), deposit samples in WIPO-recognized depositories 1.
How Much Cash Are We Talking?
Here’s the cost breakdown:
- Filing: $24 for 10 pages, $1 per extra page. A 30-page app? $44.
- Sealing: $60.
- Agent Fees: $200–500, depending on complexity. A tricky biotech patent might push it to $600.
- Translations: $50–100 if your docs need Bengali or tweaking from English.
- Maintenance: $12–50/year, rising over time.
Total? $300–800, tops. In the US, you’d drop $1,000+ just to file. Bangladesh is a budget-friendly IP haven!
How Long’s This Gonna Take?
From filing to certificate, expect 2–4 years. It’s slower than the US (2–3 years) or Europe (3–5 years), but not glacial. Delays can hit if the DPDT’s backed up or you get objections. No express lane yet, so plan your invention’s worth the wait.
Watch Out for These Hiccups
- Language Barriers: English works, but sloppy translations kill apps. Hire a pro if your agent flags it.
- Legal Twists: Some fields (like biotech or software) face stricter rules. A gene-editing method might get dicey; check with a pro.
- Enforcement: Courts work, but they’re slow. If someone rips you off, a local partner can spot it fast and lean on cultural pressure while you lawyer up.
US Inventor Hacks:
- Build rapport with your agent—trust is king here. A quick Zoom or a “thanks” email builds bridges.
- Show local value—does your invention create jobs or solve a Bangladeshi problem? That’s a golden ticket.
- Pair it with a trademark—double your protection for less hassle.

From Patent to Prosperity: Bangladesh’s Innovation Tipping Point
Patent registration in Bangladesh isn’t just legal compliance; it’s economic warfare. Consider:
- Pharmaceuticals exports hit $1.9B in 2024, all built on patent-backed R&D The DPDT received 340 patent applications in 2015 (mostly foreign), but with the 2023 Act, local filings are surging
At Zivadra, we’ve seen Bangladesh’s patent maturity accelerate faster than Dhaka’s metro rail project. With 20-year terms, utility models, and digital enforcement, innovators finally have armor.
Final Wisdom from Zivadra’s Founder: “Your idea is a seed. A patent is the fence that lets it grow into a banyan tree, without elephants trampling it.”
