Patent claims fish and fish fillets

15 November 2021 / The European Patent Office (EPO) will decide tomorrow on an opposition against a patent on fish. Patent (EP1965658) claims salmon and trout as technical inventions. The fish are fed with selected plants to influence the composition of the fatty acids in their muscles. However, it has long been known that specific diets can influence the composition of animal produce such as meat, milk, eggs and fish filets – it is neither new nor inventive.
