Tanzania Amends Trademark and Patent Laws: What Businesses and IP Owners Need to Know

By GERPAT Solutions | Intellectual Property & Corporate Compliance

Tanzania has introduced important amendments to its intellectual property framework through the Written Laws (Miscellaneous Amendments) Act, 2026 (Act No. 6 of 2026). The changes affect the Trade and Service Marks Act and the Patents (Registration) Act, with implications for brand owners, foreign investors, manufacturers, associations and patent holders.

The amendments address the recognition of certain regional intellectual property registrations, protection of well-known trademarks, registration of collective and certification marks, and the duration of patents and utility certificates.

For businesses operating in Tanzania or planning to enter the market, these changes make it important to review existing intellectual property portfolios and future filing strategies.

1. ARIPO Trademark Registrations Designating Tanzania

One of the major changes is the introduction of section 28A into the Trade and Service Marks Act.

The provision establishes statutory recognition in Tanzania for qualifying trademarks registered through the African Regional Intellectual Property Organization (ARIPO) that designate the United Republic of Tanzania, subject to the applicable legal requirements and any refusal communicated by the Registrar under the relevant Protocol.

This is significant for businesses using regional filing mechanisms to protect their brands across multiple African markets.

What should trademark owners do?

Businesses with ARIPO trademark registrations designating Tanzania should:

• Review their registration certificates and the designated territories.
• Confirm whether the Registrar communicated any refusal affecting Tanzania.
• Keep the ARIPO registration and related correspondence available for enforcement or commercial due diligence.
• Assess whether any pending opposition or infringement matter requires a review in light of the amendment.

The practical effect of an individual registration should be assessed against the statutory provision and the relevant ARIPO records.

2. Broader Recognition of Trademark Signs

The amendments expand the statutory definition of a trade or service mark to cover signs capable of distinguishing the goods or services of one undertaking from those of another.

The revised framework expressly addresses a wider range of signs, including three-dimensional marks, words, letters, numerals, colours or combinations of colours, product get-up and holograms.

This is important because brand identity is not always limited to a company name or logo. Consumers may also recognise a product through its packaging, distinctive shape, visual presentation or other identifying features.

Implications for businesses

Businesses should consider whether important brand features beyond their word marks and conventional logos warrant additional protection.

However, not every colour, shape or packaging design will automatically qualify for registration. Applicants must still satisfy the applicable legal requirements, including the requirement that the sign be capable of distinguishing the relevant goods or services.

3. Stronger Statutory Protection for Well-Known Trademarks

The introduction of section 19A provides express protection for qualifying well-known trademarks under the applicable international framework.

Importantly, the provision contemplates protection for eligible marks even where their owners do not conduct business or possess goodwill in Tanzania.

This may be particularly relevant to international brands whose reputation extends into Tanzania before they establish a local office, appoint a distributor or begin direct commercial operations.

How is a mark’s reputation assessed?

The Registrar must consider relevant factors, including:

• The level of recognition among the relevant public.
• The duration, extent and geographical reach of use and promotion.
• Relevant registrations and applications, to the extent they demonstrate use or recognition.
• Evidence of successful enforcement and recognition by competent authorities.
• The value associated with the mark.

The amendments also address remedies against confusingly similar marks and marks that may impair or take unfair advantage of the distinctive character of a well-known mark, subject to the statutory provisions.

Practical steps for brand owners

Businesses relying on well-known status should maintain organised evidence of their brand’s reputation. This may include advertising records, market research, sales information, international registrations, media coverage and records of enforcement action.

Foreign brand owners should not assume that international fame alone will automatically establish protection in Tanzania. The relevant evidence and statutory criteria remain important.

4. Introduction of Collective Trademarks

The new section 16A expressly provides for collective trade and service marks.

A collective mark distinguishes the goods or services of members of an association from those of non-members. It may be useful for eligible associations, cooperatives, producer groups and other organisations whose members operate under a shared identity.

For example, a producers’ association may seek to protect a common mark used by its members to identify goods originating from the group.

Collective marks can support consistent branding and help consumers distinguish the products or services of participating members from those offered by other traders.

Applicants should review the applicable filing requirements and the rules governing membership and use of the mark.

5. Registration of Certification Marks

The amendments also introduce section 16B, which provides for certification marks.

A certification mark may be used to distinguish goods or services based on specified characteristics, such as geographical origin, materials, manufacturing method, quality or other qualifying attributes.

Unlike an ordinary trademark used to identify one trader’s goods, a certification mark indicates that the relevant goods or services meet established standards.

The statutory framework requires the proprietor to provide the prescribed regulating instrument setting out the conditions for certification and authorised use. The proprietor must also satisfy the applicable requirements concerning its own trading activities in the goods or services being certified.

Why this matters

Certification marks may offer a useful mechanism for organisations seeking to establish and protect recognised quality or origin standards.

Before applying, the proposed proprietor should consider the certification criteria, the intended users, monitoring arrangements and the documentation required by the Registrar.

6. Trademark Applications May Be Advertised Before Acceptance

The amendments allow the Registrar, in exceptional circumstances, to advertise a trademark application before acceptance.

This gives the Registrar flexibility to invite public input in circumstances where early advertisement is considered appropriate.

Applicants should therefore monitor the status of their applications and respond promptly to official communications. Businesses with potentially conflicting rights should also remain alert to relevant trademark publications and opposition opportunities.

7. Changes to Patent and Utility Certificate Terms

The amendments to the Patents (Registration) Act address the duration of patents and utility certificates.

Under the revised provisions, a patent term is set at 20 years from the filing date, while a utility certificate term is set at 10 years from the filing date.

These changes are important for businesses managing inventions, product development and technology portfolios.

What should existing rights holders consider?

Patent and utility certificate owners should review their registration records and applicable renewal or annuity obligations.

For rights granted before the amendments came into force, the effect of the new provisions should be checked carefully. The treatment of existing rights and the calculation of expiry dates should not be assumed without reviewing the applicable statutory wording and any relevant transitional rules or official guidance.

What Businesses Should Do Now

The amendments provide a timely reason for businesses and intellectual property owners to review their protection strategies.

We recommend that businesses consider the following steps:

1. Audit existing registrations: Identify national and ARIPO trademark registrations designating Tanzania and check their current status.
2. Review brand assets: Consider whether distinctive packaging, shapes, colours or other identifying features warrant further protection.
3. Document brand reputation: Maintain evidence supporting any claim that a trademark is well known.
4. Assess collective or certification mark options: Associations and eligible organisations should review whether these registration routes fit their objectives.
5. Review patent portfolios: Check filing dates, expiry calculations and applicable maintenance obligations.
6. Monitor registry developments: Confirm procedural requirements and any further guidance issued by the relevant authorities.

The appropriate course of action will depend on the rights held, the relevant filing route and the circumstances of each business.

Conclusion

The 2026 amendments represent an important development in Tanzania’s intellectual property framework. They address regional trademark registrations, well-known marks, non-traditional signs, collective and certification marks, and the terms of patents and utility certificates.

For brand owners and technology-driven businesses, understanding these changes is essential to maintaining an effective intellectual property strategy and preparing for potential infringement or commercial disputes.
