Intellectual Property Lawyers in Tanzania Serving Clients Worldwide

At Lexglobe IP Services, we represent clients ranging from entrepreneurs to globally-recognized brands in protecting their intellectual property in Tanzania, Zanzibar and other countries throughout Africa. With offices in Dar es Salaam, Tanzania, we have broad experience protecting and enforcing intellectual property rights under the laws of Tanzania and Zanzibar, as well as under the various treaties and international frameworks that offer protection in Tanzania and elsewhere worldwide.

Our clients include individual inventors, start-up companies, local and regional established businesses, multinational corporations with global product ranges, universities and hospitals. We work closely with our clients’ executives and in-house legal departments to develop protection strategies, and we work with their inventors and designers on technical matters to make sure that their registrations are as comprehensive as possible. We understand and believe in the value of establishing a strong intellectual property portfolio, and we want to make sure that our clients’ intangible assets are secure so that they can exploit them to their full potential while avoiding infringement of other parties’ rights.
