Unity of Invention Under The European Patent Convention

Unity Of Invention Under The European Patent Convention

Under Article 82 EPC, a European patent application must "relate to one invention only or to a group of inventions so linked as to form a single general inventive concept". This legal provision is the application, within the European Patent Convention, of the requirement of unity of invention which is applicable also in many other jurisdictions.

The lack of unity (of invention), or non unity (of invention), can appear either "a priori", i.e. before taking into account the prior art, or "a posteriori", i.e. after having taken into account the prior art. An a posteriori lack of unity usually results from a lack of novelty or inventive step of the subject-matter of one independent claim.

Famous quotes containing the words unity of, unity, invention, european, patent and/or convention:

    If usually the “present age” is no very long time, still, at our pleasure, or in the service of some such unity of meaning as the history of civilization, or the study of geology, may suggest, we may conceive the present as extending over many centuries, or over a hundred thousand years.
    Josiah Royce (1855–1916)

    Jesus abolished the very concept of “guilt”Mhe denied any cleavage between God and man. He lived this unity of God and man as his “glad tidings” ... and not as a prerogative!
    Friedrich Nietzsche (1844–1900)

    The invention of photography provided a radically new picture-making process—a process based not on synthesis but on selection. The difference was a basic one. Paintings were made—constructed from a storehouse of traditional schemes and skills and attitudes—but photographs, as the man on the street put, were taken.
    Jean Szarkowski (b. 1925)

    I can never suppose this country so far lost to all ideas of self-importance as to be willing to grant America independence; if that could ever be adopted I shall despair of this country being ever preserved from a state of inferiority and consequently falling into a very low class among the European States.
    George III (1738–1820)

    There is a patent office at the seat of government of the universe, whose managers are as much interested in the dispersion of seeds as anybody at Washington can be, and their operations are infinitely more extensive and regular.
    Henry David Thoreau (1817–1862)

    Every one knows about the young man who falls in love with the chorus-girl because she can kick his hat off, and his sister’s friends can’t or won’t. But the youth who marries her, expecting that all her departures from convention will be as agile or as delightful to him as that, is still the classic example of folly.
    Katharine Fullerton Gerould (1879–1944)
