Inventors and businesses in Bangladesh now operate under a completely new patent law. The Bangladesh Patent Act, 2023, came into force on February 27, 2025, replacing a colonial-era system that had been in place for over a century. If you’ve built something original, whether it’s a product, a process, or a technical solution, this is the legal framework that protects it. At Praggo, you can connect with verified patent agents and IP professionals who understand the new law and can guide your application from start to finish.

Why Your Business Needs Patent Registration
An unprotected invention is an open invitation. Once your product or process is in the market, any competitor can study it, replicate it, and sell it without paying you a cent. Patent registration is the only way to stop that legally.
A registered patent gives you the exclusive right to make, use, sell, and import your invention in Bangladesh for up to 20 years. That exclusivity isn't just a legal shield. It's a commercial asset. Businesses with registered patents can license their inventions to other companies and earn royalty income. They can attract investors who want proof that their technology is legally protected. They can enter export markets with documented IP ownership, which many international buyers and partners require before signing contracts.
Bangladesh's graduation from Least Developed Country status in 2026 makes this even more urgent. The country will lose the TRIPS flexibilities it previously enjoyed, and full international IP standards will apply. Businesses that register now are building a foundation before the competitive landscape shifts permanently.
What Can (and Cannot) Be Patented
Understanding eligibility before you file saves you time, money, and disappointment.
What Qualifies for a Patent
Under the Bangladesh Patent Act, 2023, an invention must pass three tests to be patentable. First, it must be novel, meaning it cannot already exist in any form anywhere in the world before your application date. Second, it must involve an inventive step: it shouldn't be obvious to someone with standard knowledge in that technical field. Third, it must have industrial applicability, which means it needs to work in a real-world industry context, not just in theory.
The Act also recognizes utility model patents. This is a second tier of protection designed for smaller or incremental improvements that might not clear the full inventive-step bar. A utility model patent lasts 8 years instead of 20 and is faster and cheaper to obtain. For SMEs in Bangladesh working on product improvements rather than breakthrough inventions, this is often the more practical route.
What Cannot Be Patented?
The law draws clear boundaries. Discoveries and scientific theories cannot be patented because they belong in the public domain. Neither can mathematical methods, business methods, or computer programs on their own. Methods of medical treatment for humans are excluded as well. Traditional knowledge is also off the table, a deliberate policy choice to prevent commercial exploitation of community-held knowledge. If your invention falls into any of these categories, a patent agent can help you explore alternative protections such as trade secrets or copyright.
Understanding Patent Terms and Your Rights
A granted patent is not a one-time event. It's an ongoing legal asset with specific rights, obligations, and a defined lifespan.
Your Exclusive Rights
Once your patent is granted and sealed by the DPDT (Department of Patents, Designs and Trademarks), you hold the exclusive right to stop others from making, using, selling, offering for sale, or importing your invention in Bangladesh without your permission. These rights can be licensed to other businesses through a written agreement registered with the DPDT, which means your patent can generate revenue even while you focus on other parts of your business. You can also assign (sell) the patent outright if that fits your commercial strategy.
The 20-Year Term and Annual Renewal Fees
Your patent is valid for 20 years from the filing date. But it doesn't stay active automatically. Starting from the 6th year, you must pay annual renewal fees, called annuities, to keep the patent in force. The 2023 Act gives you a strict three-month payment window each year with no extension. Miss it, and your patent lapses. A lapsed patent can be restored within 2 years if the non-payment was genuinely unintentional, but that process adds cost and complexity. Most businesses work with a patent agent on retainer to manage these deadlines so nothing slips.
Enforcement When Someone Infringes
If a competitor copies your patented invention, you can take legal action. Infringement cases are filed in a District Court, with appeals going to the High Court Division. Courts can issue injunctions to immediately stop the infringing activity and award compensation through damages or an account of the infringer's profits. The law also provides border measures to block the import of infringing goods, which is particularly relevant for businesses in manufacturing and consumer products.
Who It's For
This service is most valuable for entrepreneurs, manufacturers, startups, and R&D teams who have developed an original product or process and want to protect it before launching or scaling. It's also relevant for businesses in pharmaceuticals, agro-processing, electronics, and consumer goods that are preparing for the post-LDC competitive environment. Legal teams at larger companies handling patent portfolio management, as well as individual inventors working independently, will also find experienced patent professionals on Praggo who can handle everything from initial filing to post-grant renewals.
Why Businesses Choose Praggo for Patent Registration
Finding a competent patent agent through word of mouth or an unverified online listing is a real risk when the stakes involve 20 years of IP protection. A mistake in the application, a missed deadline, or a poorly drafted claim can cost you the protection entirely. Praggo gives you a structured, accountable way to hire qualified IP professionals.
Verified and Qualified Professionals
Every patent agent and IP consultant on Praggo is vetted before they can list their services. You can review their credentials, past work, and client reviews before making any commitment. This matters more in a specialized field like patent law, where credentials and track record directly affect the outcome.
Transparent Pricing
Agent fees are listed upfront in BDT, so you know what you're paying before the engagement begins. Government filing fees (which are separate and paid directly to the DPDT) are clearly communicated as well. There are no surprise invoices after the work starts.
Payment Protection
Your payment is held securely by Praggo and only released to the professional once you confirm the work is complete. We accept bKash, Nagad, bank transfer, and all major local and international cards. Your money is never at risk if a deliverable isn't met.
Specialized Expertise
Patent registration under the 2023 Act involves complex claim drafting, strict procedural timelines, and knowledge of DPDT requirements that general lawyers often don't have. The professionals on Praggo specialize in IP work and stay current on regulatory changes.
Direct Communication and Support
You can discuss your invention, ask questions, and track progress directly through the platform. Praggo's support team is also available to help if any issues arise during the engagement.
