Trends in the krill fishery are currently informed by data on annual catches and by the annual notification procedure. There has been considerable discussion within the Scientific Committee over the utility of these sources of information to detect trends, and of the need to obtain more information from the krill industry. This paper uses publicly available patent databases to examine both the number and type of patents related to krill that are lodged annually. This information matches well with the catch and notification information, showing similar trends. It is suggested that the patent database be taken over by the Secretariat so that they can maintain an annual register of krill related patents which will be of use for indicating future trends in the krill fishery.
