Patent No. EP3911147 (titled "Tomato Plant Resistant To Tomato Brown Rugose Fruit Virus") was filed by Enza Zaden Beheer on Dec 9, 2019. The application was issued on Jul 16, 2025.
A tomato plant (Solanum lycopersicum) resistant to Tomato Brown Rugose Fruit Virus (TBRFV), a Tobamovirus, comprising one or more genomic sequences that encode NBS-LRR resistance proteins and/or LRR receptor-like serine/threonine-protein kinases. The plant exhibits dominant resistance to TBRFV and can be identified by specific markers. The genomic sequences provide a novel resistance mechanism against TBRFV, which is distinct from existing resistance genes against other Tobamoviruses.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
