The utopian socialist thinkers did not use the term utopian to refer to their ideas. Karl Marx and Friedrich Engels referred to all socialist ideas that were simply a vision and distant goal for society as utopian, according to Wikipedia.
Utopian socialists were likened to scientists who drew up elaborate designs and concepts for creating what socialists considered a more equal society. They were contrasted by scientific socialists, likened to engineers, who were defined as an integrated conception of the goal, the means to producing it, and the way that those means will inevitably be produced through examining social and economic phenomena.
This distinction was made clear in Engels' work Socialism: Utopian and Scientific (1892, part of an earlier publication, the Anti-Dühring from 1878). Utopian socialists were seen as wanting to expand the principles of the French revolution in order to create a more "rational" society and economic system, and despite being labeled as utopian by later socialists, their aims were not always utopian with their values often included rigid support for the scientific method and creating a society ba
A key difference between "utopian socialists" and other socialists (including most anarchists) is that utopian socialists generally don't feel class struggle or political revolutions are necessary to implement their ideas; that people of all classes might voluntarily adopt their plan for society if it were presented convincingly. They often feel their form of cooperative socialism can be established among like-minded people within the existing society and establish small enterprises designed to demonstrate their plan for society.
Utopian socialists never actually used this name to describe themselves; the term "Utopian socialism" was introduced by Karl Marx and Friedrich Engels in The Communist Manifesto in 1848, although Marx shortly before the publication of this pamphlet already attacked the ideas of Pierre-Joseph Proudhon in Das Elend der Philosophie (originally written in French, 1847) and used by later socialist thinkers to describe early socialist or quasi-socialist intellectuals who created hypothetical visions of egalitarian, communalist, meritocratic or other notions of "perfect" societies without actually concerning themselves with the manner in which these societies could be created or sustained.
1) He considered other forms of socialism to not be scientific because they denied class struggle, historical materialism and the inevitable overthrow of capitalist society by the revolution of the proletariat.
2) Utopian socialism was every form of socialism that denied Marx interpretation of communism and communist ideology of history and society, like proudhonism, blanquism, Jacobinism, Christian communism, left wing Hegelianism, nihilism or anarchism. Marx consider himself the father of scientific socialism despite the fact that he was not a worker and most of his predictions were closer to political religious prophecies than of scientific and reliable political methods.
