O.A.P.I.: A New Landmark Publication by Maître Christian Dudieu DJOMGA
SRDB Law Firm is pleased to highlight the publication of a new book by its partner in Cameroon, Maître Christian Dudieu DJOMGA, entitled:
“O.A.P.I. – The New Opposition Procedure for Trademark Registration”
Through this high-quality publication, Maître Christian Dudieu DJOMGA further confirms his standing among recognised intellectual property practitioners in Central Africa and across the OAPI region.
Since the entry into force, on 14 November 2020, of the new administrative opposition procedure for trademark registration, the legal framework of the African Intellectual Property Organization has undergone a significant evolution.
The African Intellectual Property Organization brings together 17 member states and represents a market of nearly 150 million inhabitants across more than 8.7 million km², making it a particularly strategic economic area for investors, businesses and rights holders.
This reform marks an important shift: intellectual property is no longer a niche topic reserved for specialists, but a central tool for securing, enhancing and developing business activities.
In this book, Maître Christian Dudieu DJOMGA offers a clear, structured and practical analysis of a relatively recent procedure that is set to play an increasing role in trademark disputes.
The author explains the mechanics of opposition proceedings, highlights their practical implications, analyses the first decisions issued, notably by the Higher Appeals Commission of OAPI, and provides practitioners with valuable strategic guidance.
This work stands out for the quality of its legal analysis, its practical usefulness, its accessible pedagogical approach, and its deep understanding of the African institutional environment.
As SRDB’s partner in Cameroon, Maître Christian Dudieu DJOMGA represents a new generation of professionals combining technical excellence, commercial awareness and international perspective.
His intellectual property expertise is a valuable asset for SRDB clients seeking to protect, develop or defend their intangible assets across Francophone Africa.
This publication will be of particular interest to lawyers, judges, trademark attorneys, industrial property advisers, academics, business leaders and companies facing trademark protection issues.
SRDB warmly congratulates Maître Christian Dudieu DJOMGA on this remarkable publication, which contributes to the development of business law and intellectual property across the African continent.

Recognised Practitioners’ Views
“As a perceptive jurist and a demanding practitioner, Maître Christian Dudieu DJOMGA offers a well-documented, structured and pedagogical analysis of this still recent mechanism, which is set to play an increasingly important role in trademark disputes. He does not merely describe the procedure; he explains its rationale, sheds light on its grey areas, and suggests avenues of reflection for those wishing to use it in a strategic and informed manner.”
Jackson Francis NGNIE KAMGA – Former President of the Bar – Cameroon
