Patent Opposition in DRC: OAPI Proceedings and Cobalt Mining Equipment

TL;DR
OAPI hears opposition on DRC-designated patents covering Kolwezi cobalt flotation cell impeller patents, Kinshasa mobile money POS terminal designs, and Lubumbashi copper electrowinning cathode plate geometries. OAPI Bulletin prior art supports Central African corridor challenges. See our DRC enforcement guide and Zambia enforcement article by the PatentPaper research team.

OAPI Regional Opposition in DRC

OAPI accepts opposition on patents designating Democratic Republic of Congo among member states on novelty, inventive step, and insufficient disclosure grounds.

Example: A 2024 OAPI opposition revoked a Kolwezi contractor patent on flotation cell impeller blade root fillet radius claims after opponents cited a 2017 Gecamines engineering bulletin describing identical impeller geometry for cobalt-copper sulfide concentrator circuits.

Cobalt and Copper Mining Equipment

Kolwezi and Tenke Fungurume operators oppose patents on solvent extraction mixer-settler weir height control, electrowinning cathode starter sheet alloy compositions, and SAG mill liner bolt hole pattern patents.

Hydropower and Inga Dam Infrastructure

Inga project contractors challenge patents on Francis turbine runner blade root fillet patents and switchyard SF6 breaker arc quenching nozzle designs.

Fintech and Mobile Payment Hardware

Kinshasa fintech competitors oppose patents on POS terminal biometric fingerprint sensor calibration methods and solar-powered agent kiosk battery charge controller designs.

Cocoa and Agricultural Processing

Equateur province processors deploy opposition using prior art on cocoa fermentation box ventilation slot spacing and drying bed solar tunnel airflow distribution patents.
