An unpatented idea alone is difficult to sell, since without a patent there's no exclusive legal right for a buyer to acquire; most successful sales involve at least a filed priority application (such as a US provisional) establishing a priority date. Once patented or patent-pending, an invention can be sold via direct assignment or licensed for ongoing royalties.
