§ 2 .

A patent is not granted for preparations of provisions, drinks, and medicines, nor for discoveries, inventions, or improvements, the practice of which is forbidden from public motives in regard to health, morality, or security, or the general in­terest of the State, according to the legal ordinances.

§ 3 .

An exclusive patent can only be granted for a new discovery, invention, or im­provement, which it is intended to introduce into Austrian territory from abroad, when the operation of it is likewise limited abroad by an exclusive patent.

Such grant, however, can only be made to the owner of the foreign patent, or to his legal representative or agent. Without these limitations, a patent is not allowed for an invention, discovery, or improvement made abroad, but not yet in operation at home.

§ 4 .

A patent for an improvement of an already known article, or one protected by an exclusive patent, is only granted with the limitation that it extends only to the improved portion, and not to the entire article.

§ 5 .

An exclusive patent is not granted for a scientific principle, or a purely scientific proposition, even where the principle or proposition is capable of immediate applica­tion to industrial objects ; but every new application of such principle or proposition, by means of which a new industrial product, a new means, or a new method of production is brought about, is certainly patentable.

* 6 .

The union of two or more discoveries, inventions, or improvements differing from each other in one patent is only allowed when these discoveries, inventions, or improvements refer to one and the same article, as component parts, or operative means.
