Patent No. EP3196301 (titled "Methods And Compositions For The Treatment Of Monogenic Diseases") was filed by Sangamo Biosciences on Mar 15, 2013. The application was issued on Oct 17, 2018.
A method to treat lysosomal storage diseases like Gaucher's disease by genetically modifying cells to produce the missing enzyme. The method involves inserting a corrective gene encoding the enzyme into cells using engineered nucleases like TALENs or CRISPR/Cas systems. The inserted gene is integrated into the genome and expressed, allowing the modified cells to produce the enzyme and treat the disease. The nucleases are designed to specifically target safe harbor genes like albumin to avoid disruption of essential genes. This enables production of therapeutic proteins at therapeutically relevant levels when the modified cells are administered to patients.

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.
