Patent Registration & IP Legal Advisory in Bangladesh

Intellectual property (IP) protection is among the most strategically important legal actions any business, inventor, or creative professional can take. In Bangladesh, a country that is rapidly evolving from a manufacturing-led economy to one that also values technology, innovation, and brand equity, securing IP rights has never been more commercially critical. Whether you are an inventor with a novel technical solution, a startup building a recognizable brand, a software developer producing original code, or a manufacturer with a uniquely designed product, the Bangladesh intellectual property regime now offers stronger legal protection than at any previous point in the country's history.

Bangladesh's intellectual property framework is administered primarily by the Department of Patents, Industrial Designs and Trademarks (DPDT) under the Ministry of Industries, and the Copyright Office under the Ministry of Cultural Affairs. The DPDT oversees patent registration, trademark registration, and industrial design registration, while copyright registration is handled by a separate dedicated office. Together, these institutions operate a system covering four principal categories of protectable IP: patents, trademarks, copyrights, and industrial designs.

A landmark moment in Bangladesh's IP history arrived with the enactment and enforcement of the Bangladesh Patent Act, 2023 (Act No. 53 of 2023), which came into force on 27 February 2025. This legislation replaced the outdated Patents and Designs Act of 1911 — a colonial-era statute that had served for over a century with minimal reform — and introduced a modern, structured patent regime aligned with the TRIPS Agreement and prevailing international standards. Similarly, the Bangladesh Industrial Design Act, 2023 (Act No. 22 of 2023) came into force in the same period, replacing the old design provisions and establishing a standalone, contemporary framework for design protection. These twin legislative reforms, combined with ongoing digitization of the DPDT's services, signal a decisive improvement in the country's IP environment for both domestic and international right holders.

This comprehensive guide explains every aspect of patent registration and broader IP legal advisory in Bangladesh — covering patents, trademarks, copyrights, and industrial designs — including the applicable fees, step-by-step procedures, timelines, foreign applicant requirements, enforcement mechanisms, and professional advisory costs. If you require expert assistance navigating any of these processes, our IP advisory team at Aeenx is available for a tailored consultation.

Bangladesh law recognizes four main categories of registrable intellectual property, each serving a distinct purpose and governed by its own statute. Understanding which type of IP protection applies to your creation is the essential first step before approaching the DPDT or any advisory professional.

Patents — Protecting Inventions

A patent grants the owner exclusive rights over a technical invention for a defined period, during which no third party may manufacture, use, sell, or import the patented product or process without authorization. Under the Bangladesh Patent Act, 2023, a standard patent grants protection for 20 years from the filing date. The Act also recognizes utility model patents — a second-tier protection designed for minor or incremental innovations that may not satisfy the strict inventive-step standard for a full patent. A utility model offers an 8-year protection term and provides a faster, lower-cost path for local innovators and SMEs to protect incremental improvements.

Trademarks — Protecting Brand Identity

A trademark is a sign capable of distinguishing one business's goods or services from those of competitors — it may be a word, logo, slogan, colour, shape, or combination thereof. In Bangladesh, trademark registration is governed by the Trade Marks Act, 2009 and the Trade Marks Rules. A registered trademark grants the proprietor exclusive rights to use the mark in commerce in the specific class or classes for which it is registered. Initial registration is valid for 7 years from the application date and is renewable every 10 years thereafter for an indefinite period. Bangladesh follows a first-to-file system for trademark priority — meaning that the party who files first generally has superior rights, regardless of prior use.

Copyright — Protecting Creative Works

Copyright protection in Bangladesh is governed by the Copyright Act, 2023, which replaced earlier legislation. Unlike patents and trademarks, copyright arises automatically upon the creation of an original work — no formal registration is required for the right to exist. However, registration with the Bangladesh Copyright Office (BCO) provides vital evidentiary advantages: a registered copyright is presumed valid and constitutes prima facie proof of ownership, which is critically important in infringement disputes. Works eligible for copyright protection include literary, artistic, musical, and dramatic works; films; sound recordings; broadcasts; and software. The protection term is generally the life of the author plus 60 years.

Industrial Designs — Protecting Visual Aesthetics

An industrial design right protects the unique visual or aesthetic appearance of a product — its shape, pattern, lines, colours, texture, or ornamentation — as distinct from its technical function (which is the domain of patents). In Bangladesh, the Bangladesh Industrial Design Act, 2023 governs design registration at the DPDT. An initial registration term of 10 years applies, renewable for three additional periods of 5 years each, giving a maximum total protection period of 25 years. Design registration is particularly valuable for manufacturers of consumer goods, fashion products, packaging, and any product where the visual appearance is a material part of its market appeal.

Patent registration in Bangladesh follows a structured multi-phase process governed by the Bangladesh Patent Act, 2023. The authority responsible for all patent proceedings is the Department of Patents, Industrial Designs and Trademarks (DPDT), whose administrative head — the Director General — holds powers equivalent to those of a civil court under the new legislation. The DPDT is headquartered in Dhaka, and all patent applications are submitted there.

Step 1 — Determine Patentability

Before investing in a patent application, the inventor or applicant must assess whether the invention satisfies the fundamental patentability criteria under Section 2 and related provisions of the Bangladesh Patent Act, 2023. An invention must meet all four conditions: Novelty (the invention must not form part of the global prior art — meaning it has not been publicly disclosed anywhere in the world before the filing or priority date); Inventive Step (the invention must not be obvious to a person skilled in the relevant technical field — sometimes called non-obviousness); Industrial Applicability (the invention must be capable of being manufactured or used in any industry); and Patentable Subject Matter (not all creations qualify — the Act explicitly excludes discoveries of natural phenomena, abstract mathematical theories, methods of medical treatment, traditional knowledge, and software lacking a technical character, among others).

Step 2 — Prepare the Patent Application

A patent application may be filed with either a Provisional Specification or a Complete Specification. Filing a provisional specification allows the applicant to secure an early priority date while the full invention is still being refined — this is particularly useful for inventors who are still finalizing technical details. If a provisional specification is filed, a complete specification must follow within 12 months of the provisional filing date. Failure to file the complete specification within this period results in the application being deemed abandoned. The Complete Specification must contain: a full description of the invention (field, prior art, objectives, and detailed working description); drawings or diagrams where applicable; the patent claims — which precisely define the legal scope of the monopoly being sought; and an abstract. The claims are the most legally critical element of the specification: overly narrow claims provide little commercial protection, while overly broad claims risk rejection or future invalidity challenges.

Step 3 — File the Application with DPDT

The application is submitted to the DPDT in the prescribed form, accompanied by the applicable government fees. The date of receipt of a complete application constitutes the official filing date, which determines priority rights. For foreign applicants, application must be made through a Bangladeshi local legal representative — direct filing by foreign nationals is not permitted under DPDT procedure. Required documents include: the completed application form (Form 1 or 1A for joint applications); the complete specification in Form 3A in English; drawing sheets (original in tracing paper with a photocopy duplicate); a forwarding letter addressed to the Director General, DPDT; payment evidence (bank draft or treasury challan); a power of attorney if an agent is appointed; and a priority document if claiming Paris Convention priority from an earlier foreign application (to be submitted within 3 months of the Bangladesh filing date).

Step 4 — Formality Check and First Publication

Upon receipt of the application, the DPDT conducts a formality check to verify that all required documents have been submitted and that the application is formally complete. If deficiencies are identified, the applicant is given a specified period to correct them — failure to do so results in abandonment of the application. After the formality check is passed, the application is published in the DPDT's gazette (first publication / pre-grant publication). A publication fee is payable at this stage. Third parties are entitled to file a pre-grant opposition within 6 months of this first publication, challenging the patentability of the invention on grounds such as lack of novelty, lack of inventive step, or non-patentable subject matter.

Step 5 — Request for Substantive Examination

The substantive examination does not occur automatically — the applicant must formally request it within 36 months of the filing or priority date (extendable by 3 months on application, and by a further 3 months with penalty fees). Failure to request substantive examination within the stipulated period results in the application being deemed abandoned. Upon request and payment of the examination fee, the DPDT examiner reviews the application against the patentability criteria — novelty, inventive step, and industrial applicability — and assesses compliance with all technical and formal requirements of the Patent Act, 2023.

Step 6 — Examination, Objections, and Grant

The examiner may raise objections (office actions) requesting clarifications, amendments to claims, or additional information. Applicants must respond within the prescribed period. The DPDT may also require disclosure of corresponding foreign applications and their examination status within 90 days of demand, with updates every 6 months thereafter. If the examiner is satisfied that all requirements are met, the patent proceeds to grant. If objections cannot be overcome, the application is rejected. Upon grant, the patent certificate is issued, and the patentee acquires the exclusive right to make, use, sell, and import the patented invention throughout Bangladesh for the patent term.

The government fees for patent registration in Bangladesh are set by the DPDT and are payable at various stages of the application process. All fees are payable via bank draft or treasury challan. The fee structure under the Bangladesh Patent Act, 2023 and the DPDT's published schedule is as follows:

Fee Category	Ordinary Application	Priority Application (Foreign)
Application fee (up to 25 pages, 10 claims)	BDT 2,000	BDT 10,000
Each additional page beyond 25 pages	Per page rate applies	Per page rate applies
Each additional claim beyond 10 claims	Per claim rate applies	Per claim rate applies
Publication fee (pre-grant)	Per DPDT schedule	Per DPDT schedule
Substantive examination request fee	Per DPDT schedule	Per DPDT schedule
Annual renewal fees (Year 5 onward)	Annual, per schedule	Annual, per schedule
Late renewal surcharge (within 90-day grace)	Additional late fee	Additional late fee

Note: The DPDT fee schedule is subject to periodic revision. Fees quoted above reflect the publicly available schedule. Always verify current fees with the DPDT directly at dpdt.gov.bd before filing.

Annual Renewal Fees (Patent Maintenance)

A granted patent does not remain in force automatically for its full 20-year term without payment of annual renewal (maintenance) fees. Renewal is required from the 5th year onward, with the fee for each year payable before the expiry of the previous year's term. A grace period of 90 days applies for late payment, but a surcharge is levied. Failure to pay renewal fees within the grace period results in the patent lapsing. Annuity fees may be paid in advance for several years simultaneously, which is administratively convenient for applicants managing large patent portfolios. The renewal fee escalates progressively as the patent ages, reflecting the increasing commercial value typically associated with mature patents that remain in force.

Total Estimated Patent Cost (Lifecycle)

When all government fees — application fee, publication fee, examination fee, grant fee, and 20 years of annual renewal fees — are aggregated, the total government cost of maintaining a standard patent from filing through the full 20-year term runs to approximately BDT 50,000 to BDT 1,50,000 depending on the number of pages, claims, and applicable renewal fee schedule. Professional patent drafting and prosecution fees (discussed in the professional fees section below) are additional and typically represent the largest single cost component for most applicants.

Patent registration in Bangladesh is not a rapid process. Applicants must plan for a multi-year timeline from filing through to grant. The Bangladesh Patent Act, 2023 introduces defined procedural timelines that provide greater predictability than existed under the old regime, but the inherent complexity of substantive patent examination means that the overall process typically takes between 2 and 4 years for a straightforward application.

Stage	Deadline / Typical Duration	Key Action Required
Provisional to Complete Specification	Within 12 months of provisional filing	File complete specification
Paris Convention Priority Claim	Within 12 months of first foreign filing	File Bangladesh national application
Priority Document submission	Within 3 months of Bangladesh filing date	Submit certified copy of priority application
Formality Check	DPDT undertakes after filing	Respond to any deficiency notices promptly
Pre-grant Publication	Typically 12–18 months from filing	Pay publication fee
Pre-grant Opposition Window	6 months from first publication	Third parties may oppose; respond if necessary
Request for Substantive Examination	Within 36 months of filing/priority date	File request and pay examination fee
Foreign Application Disclosure	Within 90 days of DPDT demand	Submit foreign examination reports; update every 6 months
First Annual Renewal	Before expiry of Year 4	Pay Year 5 renewal fee
Total Filing to Grant (typical)	2–4 years	Active follow-up throughout

Missing any of these critical deadlines — particularly the 36-month window for requesting substantive examination — results in permanent abandonment of the application, with no possibility of revival. This makes active docketing and calendar management an essential part of any patent strategy. For applicants managing multiple applications or complex technology portfolios, engaging an experienced IP advisory service is strongly recommended to prevent deadline misses. Contact Aeenx for deadline monitoring and full-service patent prosecution management.

Trademark registration in Bangladesh is governed by the Trade Marks Act, 2009 and the Trade Marks Rules. The DPDT is the registering authority, and Bangladesh adopts a first-to-file principle — meaning that filing date is the primary determinant of priority between competing applicants, rather than prior commercial use. This makes early filing a strategic imperative for any business investing in brand development in Bangladesh.

Who Can Register a Trademark

Any person — whether an individual, company, partnership, or foreign entity — who claims to be the proprietor of a trademark may apply for registration. Foreign applicants must appoint a locally-based trademark agent or attorney to file and manage the application on their behalf; direct filing by foreign entities without local representation is not permitted. Bangladesh uses the Nice Classification system (an international standard categorizing all goods and services into 45 classes), and applicants must select the appropriate class or classes for their goods and services. Filing in multiple classes requires a separate application and fee for each class.

Pre-Filing Trademark Search

Before filing, a thorough search of the DPDT's trademark register is strongly recommended to identify any conflicting existing registrations or pending applications. While a trademark search is not mandatory under the law, submitting an application that conflicts with a prior registered mark risks rejection after examination, wasting both the filing fee and the time invested. A formal search is conducted by submitting Form TM-4 along with the prescribed search fee to the DPDT. The search typically takes 2 to 3 working days.

Application Filing

The trademark application is filed with the DPDT (or through the online portal). Required information and documents include: particulars of the mark (word mark, logo, device, or combination); the applicant's name, address, and business status (manufacturer, merchandiser, or service provider); specification of goods or services and the relevant class number; a statement of user or proposed-to-be-used declaration; power of attorney (Form TM-10) for agents representing foreign applicants; and proof of priority if claiming Paris Convention priority. Payment of the filing fee is required at submission.

Examination, Publication, and Opposition

The DPDT examiner reviews the application for compliance with absolute and relative grounds for refusal — the mark must be distinctive, not descriptive, not deceptive, and not confusingly similar to an existing registered mark. If the examiner is satisfied, a Letter of Acceptance is issued and the mark is published in the official Trade Marks Journal. Any person may file an opposition within 2 months of publication (by submitting Form TM-5 with the opposition fee of BDT 2,000). If the applicant needs to defend against opposition, a Counter-Statement (with a BDT 1,500 government fee) may be filed within 2 months of receiving the notice of opposition. Contested oppositions typically add 6 to 12 months to the overall registration timeline. If no opposition is filed, or opposition proceedings are resolved in the applicant's favour, the Registrar notifies the applicant to pay the final registration fee, following which the Certificate of Registration is issued.

The official government fees for trademark registration in Bangladesh are fixed by the DPDT and are payable at each stage of the process. The fee structure is relatively straightforward compared to patents, with fees applied on a per-class basis throughout the trademark lifecycle.

Fee Item	Government Fee (BDT)	Notes
Preliminary trademark search (Form TM-4)	~2,000 + 15% VAT	Optional but recommended
Trademark application filing fee (per class)	3,500 – 5,000	Per class; + 15% VAT
Notice of opposition (Form TM-5)	2,000	Third party filing
Counter-statement fee (applicant response)	1,500	Applicant defending opposition
Journal publication fee	Per DPDT schedule	Payable within 1 month of acceptance
Registration certificate fee (Form TM-11)	Per DPDT schedule	Payable after opposition period
Trademark association fee (if triggered)	USD 20 per cited mark	Only if similar marks owned by same proprietor
Renewal fee (Form TM-12) — every 10 years	~3,500 – 20,000	Varies; payable before expiry
Late renewal surcharge	Additional surcharge	Restorable within 12 months after expiry

Over the full lifecycle of a trademark — from initial search through registration and the first 10-year renewal — the total official government fees per class typically amount to approximately BDT 30,000 to BDT 35,000. Professional advisory and agent fees are additional. For businesses registering marks across multiple classes (for example, a consumer brand that covers both goods and services), multiply these costs by the number of classes filed.

Trademark Association Fee — An Often-Overlooked Cost

One particularly important fee that frequently surprises applicants is the trademark association fee (citation fee), governed by Section 20–21 of the Trade Marks Act, 2009. This fee arises when an applicant owns or has previously filed multiple marks in the same class that are similar in name, logo, or overall commercial appearance. The DPDT's internal system identifies these similarities only after the mark has been accepted and the standard registration fee has been paid — at which point a demand notice for USD 20 per cited mark is issued. This fee must be paid within 30 days; non-payment can result in rejection of the application even at this late stage. Applicants managing brand families or portfolios of related marks must budget for this contingent cost.

Copyright in Bangladesh is now governed by the Copyright Act, 2023, which updated the country's legal framework to cover digital works, software, traditional knowledge, and folklore alongside classical creative works. As noted above, copyright arises automatically at the moment of creation of an original work — registration is not a prerequisite for the right to exist. However, formal registration with the Bangladesh Copyright Office (BCO), accessible at bcoecopyright.gov.bd, provides powerful legal benefits that make it indispensable for commercial creative work and software.

What Can Be Registered

Works eligible for copyright registration under the Copyright Act, 2023 include: literary works (novels, articles, academic texts, scripts); artistic works (paintings, drawings, sculptures, photographs); musical works with or without accompanying lyrics; sound recordings and broadcasts; films and audiovisual works; software and computer programs; architectural works; and works of traditional knowledge and folklore. Both published and unpublished works can be registered. The applicant must be the author, creator, publisher, exclusive licensee, or a company that owns the copyright through an employment relationship or assignment.

Copyright Registration Procedure

The copyright registration process in Bangladesh is relatively straightforward compared to patent or trademark registration. Applications can be submitted either online through the BCO's e-Copyright portal at bcoecopyright.gov.bd or physically at the Copyright Office. Required documents include: the completed application form; a copy or sample of the work being registered (in digital or physical form as appropriate); proof of payment of the prescribed fee; a deed of transfer from collaborators where applicable (for joint works); a power of attorney if filing through an authorized agent; and for software, a description of its usability and functionality. Upon submission, the BCO examines the application and, if satisfied, issues a Certificate of Copyright Registration, which serves as legal proof of ownership and is critical evidence in any infringement proceedings.

Copyright Registration Fees

The official government fee for copyright registration is among the lowest of all IP registration types in Bangladesh. The primary application processing fee is approximately BDT 1,000 for most categories of creative works, with the precise amount varying by work category and subject to periodic administrative revision. Payment is made via Treasury Challan at a designated bank (Bangladesh Bank or Sonali Bank) under the relevant government revenue code, or through the online payment portal linked from the Copyright Office website. The total out-of-pocket cost for self-filing a copyright registration — government fee plus any ancillary document preparation costs — is typically well under BDT 5,000. Professional service fees for agent-assisted filing add BDT 3,000 to BDT 15,000 depending on the provider and complexity of the work.

Industrial design registration protects the visual or aesthetic appearance of products — encompassing shape, configuration, pattern, colour, graphic user interface elements, calligraphy, and ornamental features — as defined by the Bangladesh Industrial Design Act, 2023 (Act No. 22 of 2023). This law replaced the design provisions formerly embedded in the outdated Patents and Designs Act, 1911, and introduced a standalone, modern framework aligned with international standards.

Eligibility and What Qualifies

Any person claiming to be the proprietor of a new or original design not previously disclosed publicly anywhere in the world may apply for registration. The design must have novelty — it must not have been made available to the public by publication, exhibition, trade, or any other means before the filing date. It must also be capable of being applied to an industrially produced article (the "industrial applicability" requirement). Purely functional features that are dictated solely by technical necessity are not registrable as designs; the protection covers aesthetic visual features only. If multiple co-designers created a design jointly, they may apply for joint registration. Where a design is created by an employee specifically under a contract for design creation, the employer's right to register is presumed unless the contract provides otherwise.

Filing and Examination

The application is filed with the Director General, DPDT. Foreign applicants must appoint a locally-based Design Representative — direct filing without local representation is prohibited. The application must include: the completed prescribed form; representations of the design (drawings, photographs, or other visual materials showing the design from all relevant angles); proof of payment of the prescribed fee; and a power of attorney if filing through an agent. Each design generally requires a separate application, although multiple articles may be included in one application where the design remains identical across all articles. The DPDT conducts a formality and substantive examination, assessing novelty and originality. After the accepted design is published on the DPDT website or e-Gazette, third parties have 30 days to file a written opposition. The Director General decides any opposition in the prescribed manner.

Design Registration Term and Renewal

Initial registration is valid for 10 years from the filing date. The registration can then be renewed for three further consecutive periods of 5 years each — providing a maximum total protection period of 25 years. Renewal applications must be filed with the prescribed renewal fee before the expiry of the current term, with a 6-month grace period available subject to additional surcharge fees. Failure to renew within the grace period results in the design registration lapsing. Any assignment or license of a registered design must be formally recorded with the DPDT to be effective against third parties — an unrecorded transfer creates no rights vis-à-vis third parties.

Bangladesh's membership in the Paris Convention for the Protection of Industrial Property has significant practical implications for international applicants seeking IP protection in the country. The Paris Convention is the foundational multilateral treaty governing cross-border IP rights and is administered by the World Intellectual Property Organization (WIPO). Bangladesh's adherence to this convention means that foreign applicants who have already filed patent, trademark, or design applications in their home country can benefit from the priority right mechanism when filing in Bangladesh.

Priority Rights Under the Paris Convention

Under the Paris Convention priority system, a foreign applicant who files a patent application in a Paris Convention member country can file a corresponding national application in Bangladesh within 12 months of the original foreign filing date — and claim the original filing date as the priority date for the Bangladesh application. For trademark and industrial design applications, the priority window is 6 months from the first foreign filing. The Bangladesh application will be treated as if it had been filed on the original foreign priority date, which is critical for establishing priority over any third-party applications or disclosures that may arise in the intervening period. To claim priority, the applicant must submit a certified copy of the original foreign application to the DPDT within the prescribed period (3 months from the Bangladesh filing date for patents).

Bangladesh Is Not a PCT Member State

A critically important point for international patent applicants is that Bangladesh is not a member of the Patent Cooperation Treaty (PCT). The PCT is the WIPO-administered international patent filing system that allows a single "international application" to simultaneously seek patent protection in over 150 member countries. Because Bangladesh is not a PCT member, it is not possible to designate Bangladesh in a PCT international application. Foreign patent holders wishing to protect their inventions in Bangladesh must file a direct national application with the DPDT — either as a Paris Convention priority application (within 12 months of the home-country filing) or as an ordinary domestic application. This creates an important distinction compared to filings in most other major markets, and international patent strategies must account for Bangladesh's non-PCT status with a separate national filing plan.

Local Representative Requirement

For all IP types — patents, trademarks, and industrial designs — foreign nationals and foreign entities must appoint a locally-based representative to file and manage their applications at the DPDT. Appointment is formalized through a notarized and, where required, apostilled or consularly legalized Power of Attorney in favour of the Bangladesh representative. Translation costs for foreign-language documents, notarization charges, and consular legalization fees represent additional costs that international applicants must factor into their Bangladesh IP filing budget. These costs typically range from BDT 10,000 to BDT 40,000 depending on the volume of documents and the country of origin.

Bangladesh as an LDC and TRIPS Flexibilities

Bangladesh holds Least Developed Country (LDC) status under United Nations classification, which provides certain flexibilities under the TRIPS Agreement (the WTO Agreement on Trade-Related Aspects of Intellectual Property Rights). LDC flexibilities have historically included transitional periods during which Bangladesh was not obligated to extend certain forms of patent protection to pharmaceutical products — a provision of significant importance to Bangladesh's thriving generic pharmaceutical industry. The interplay of LDC flexibilities, the new Patent Act, 2023, and evolving international IP obligations makes Bangladesh's pharmaceutical patent landscape particularly nuanced. Specialized advisory is recommended for pharmaceutical and biotech companies assessing IP strategy in Bangladesh.

Registering intellectual property is only the first step — the commercial value of IP rights is realized through active enforcement against infringers. Bangladesh's legal framework provides multiple avenues for IP right holders to enforce their rights, including civil litigation, criminal proceedings, administrative action at the DPDT, and border protection measures.

Civil Remedies for Patent and IP Infringement

Patent infringement lawsuits in Bangladesh are filed in the District Court having territorial jurisdiction over the place where the infringing act occurred or where the defendant carries on business. Appeals from District Court decisions in IP matters are heard by the High Court Division of the Supreme Court of Bangladesh. Civil remedies available to a successful IP plaintiff include: injunctions (both interlocutory/temporary injunctions pending full trial and permanent injunctions after judgment) to stop ongoing infringing activity; monetary compensation in the form of damages (calculated to compensate the plaintiff for actual loss) or an account of profits (requiring the defendant to disgorge the profits made from the infringement); and orders for delivery up or destruction of infringing goods or materials. Under the Bangladesh Patent Act, 2023, the burden of proof in patent infringement cases generally lies with the patent holder, but may shift to the defendant in cases involving process patents for new products — where the defendant must prove that the accused process differs from the patented process.

Criminal Remedies

Trademark infringement and copyright infringement carry criminal consequences under Bangladeshi law, including fines and imprisonment for repeat or egregious offenders. The Trade Marks Act, 2009 provides for criminal proceedings against persons who fraudulently apply registered marks to goods or services, or who falsify trade mark registers. The Bangladesh Patent Act, 2023 similarly provides for criminal sanctions for wilful patent infringement and fraudulent conduct in patent proceedings. Criminal proceedings are initiated by filing a First Information Report (FIR) with the relevant police station or by lodging a complaint directly before a Magistrate's court.

Border Measures

Bangladesh law provides for border protection measures to intercept the importation of IP-infringing goods — counterfeits and pirated products. Customs authorities can be engaged to detain suspected infringing shipments at ports of entry pending inspection and verification against registered IP rights. IP right holders who believe their rights are being infringed through imports should register their IP rights with the relevant customs authority and maintain active engagement with border enforcement agencies to enable effective interception.

Opposition Proceedings at the DPDT

As an alternative or complement to court action, IP disputes can also be addressed through administrative proceedings at the DPDT — particularly through the pre-grant and post-grant opposition mechanisms available for patents, trademarks, and designs. These DPDT-level proceedings are generally faster and less expensive than full litigation in the civil courts, and are the preferred first-line mechanism for challenging the grant or validity of a competitor's IP registration. If you need expert IP dispute strategy advice, Aeenx's IP advisory team can assist with both DPDT proceedings and civil litigation support.

While certain IP filings — particularly straightforward copyright registrations — can be managed independently by applicants familiar with the online portals, the vast majority of patents, trademark applications, and design registrations are best handled with professional IP advisory assistance. The technical complexity of patent drafting, the strategic considerations in trademark clearance, and the procedural intricacies of DPDT practice all create significant risk of costly errors for unrepresented applicants.

Patent Drafting and Prosecution

Patent advisory fees represent the most substantial professional cost in IP registration. The quality of a patent specification — and especially the claims — is the single most important factor determining the commercial strength and enforceability of the resulting patent. A poorly drafted patent may be narrow, easily designed around by competitors, or vulnerable to validity challenges. Professional patent drafting in Bangladesh by an experienced IP advisor or patent agent typically costs:

Patent Service	Typical Professional Fee (BDT)
Prior art search and patentability opinion	10,000 – 30,000
Drafting provisional specification	15,000 – 40,000
Drafting complete specification (simple invention)	30,000 – 80,000
Drafting complete specification (complex/technical)	80,000 – 2,50,000+
Patent prosecution (responding to office actions)	10,000 – 40,000 per response
Full patent filing and prosecution package	60,000 – 3,00,000+
Foreign application package (for non-PCT countries)	Per country; USD 1,000–5,000+

Trademark Advisory Fees

Trademark Service	Typical Professional Fee (BDT)
Trademark search and clearance opinion	5,000 – 15,000
Trademark application filing and management	8,000 – 25,000 per class
Opposition response / counter-statement	15,000 – 50,000
Trademark renewal management	5,000 – 15,000 per class
Assignment or license recordal	10,000 – 25,000

Copyright and Design Advisory Fees

Service	Typical Professional Fee (BDT)
Copyright registration (creative work / software)	3,000 – 15,000
Industrial design application and management	15,000 – 50,000
IP portfolio audit and strategy advisory	20,000 – 1,00,000+
IP due diligence (for M&A or investment)	50,000 – 3,00,000+

These professional fee ranges are market estimates. Actual fees vary significantly by the complexity of the matter, the experience of the advisor, and the scope of services engaged. When evaluating service providers, always request a clear separation between government fees (fixed and payable to the DPDT) and professional service fees (negotiable and payable to the advisor). For a transparent, no-obligation quotation tailored to your specific IP needs, contact Aeenx's IP advisory team.

The following table consolidates the estimated costs for each category of IP registration in Bangladesh, providing a practical reference for budget planning. All amounts are approximate and reflect conditions as of 2025. Both government fees and professional service fees are included to give a realistic total cost picture.

IP Type	Govt. Filing Fee (BDT)	Professional Fee (BDT)	Total Estimate (BDT)	Protection Term
Copyright Registration	~1,000	3,000 – 15,000	4,000 – 16,000	Life + 60 years
Trademark (1 class)	~3,500 – 5,000	8,000 – 25,000	12,000 – 30,000	7 yrs + renewals
Industrial Design	Per DPDT schedule	15,000 – 50,000	20,000 – 60,000	Up to 25 years
Patent (domestic, ordinary)	2,000 + examination fees	60,000 – 3,00,000	65,000 – 3,20,000	20 years

Patent renewal fees (paid annually from Year 5 onward for 20 years) add significantly to the lifetime cost of patent protection and must be factored into long-term IP budgets. Similarly, trademark renewal every 10 years (approximately BDT 20,000 per class per renewal including VAT) is a recurring cost that brand owners must plan for indefinitely as long as the mark remains commercially relevant.

Navigating Bangladesh's IP registration system efficiently requires not only knowing the rules but also understanding the practical pitfalls that most commonly derail or inflate the cost of IP protection. The following tips reflect common-sense best practices and frequent error patterns observed in IP filings before the DPDT and in IP enforcement proceedings.

Strategic Tips to Optimize Your IP Protection

• File early and file first. Bangladesh's trademark system is first-to-file. For patents, the filing date determines priority. Delay in filing means risk — a competitor or even a bad-faith filer could secure rights that should have been yours. Once you have committed to a brand name or invention, file without unnecessary delay.
• Conduct a thorough prior art and trademark search before filing. For patents, a prior art search helps assess whether your invention is truly novel before investing heavily in a full application. For trademarks, a clearance search prevents filing a mark that conflicts with an existing registration and faces near-certain rejection. These upfront searches save significantly more money than they cost.
• Protect multiple elements of your brand separately. If your brand has a distinctive name, a logo, and a slogan, these are three separate protectable assets. Filing each as a separate trademark application provides maximum flexibility and the strongest independent protection for each element.
• Use provisional patent specifications strategically. If your invention is still being refined, filing a provisional specification immediately locks in your priority date at lower cost and with less technical documentation than a complete specification. The 12-month window to file the complete specification gives you time to finalize the invention details.
• Register copyrights for commercial works even though registration is not mandatory. The evidentiary advantage of a registered copyright — prima facie proof of ownership — is invaluable in infringement disputes, particularly for software, creative agencies, and content businesses where copying is frequent and proof of originality is contested.
• Plan your IP portfolio holistically. The strongest IP protection typically involves layering multiple forms of IP — for example, patenting the functional aspects of a product, registering the design for its visual appearance, and trademarking the brand name. An integrated IP strategy provides overlapping, reinforcing protection that is much harder for competitors to design around than any single IP right in isolation.

Common Mistakes That Prove Costly

• Public disclosure before filing. Under Bangladesh's Patent Act, 2023 and the Industrial Design Act, 2023, any public disclosure of an invention or design anywhere in the world before the filing date destroys novelty and bars registration. Never present, publish, display, or market your invention or design before filing. This is the single most common and most devastating IP mistake made by inventors and designers.
• Missing the 36-month examination request deadline for patents. An application not presented for substantive examination within 36 months of filing is permanently deemed abandoned. There is no restoration mechanism. Always docket this deadline from the day of filing and monitor it actively.
• Treating trademark registration as a one-time event. Many businesses register their trademark and then forget about renewal deadlines. A trademark removed from the register for non-renewal immediately becomes available for third parties to file — potentially including competitors seeking to exploit your brand's equity. Set renewal reminders well in advance of expiry.
• Filing in too few trademark classes. Under-registering across trademark classes leaves your brand exposed in business areas adjacent to your current operations. As your business diversifies, unregistered classes may allow infringers or competitors to register your mark in those classes legitimately. Consider your growth trajectory when selecting classes at the time of initial filing.
• Failing to record assignments and licenses. Under both the Patents Act and the Trade Marks Act, assignments and license agreements that are not formally recorded with the DPDT are ineffective against third parties. This means an unrecorded licensee or assignee may not be able to enforce their rights even if the agreement is otherwise legally valid between the parties. Always record IP transactions formally.
