Section VIII.
Special Regulations in relation to Sole Patents granted before the present Law came
into operation , and still valid.
§ 51.
In order to secure to the proprietors of patents still valid and issued on the basis of the ordinance of 31st March 1832, the advantage of a more extended operation of them, similar to those issued in accordance with the present law, they are granted the privilege of establishing their patent-rights in those Crown lands of the empire as well, in which the patent law of 31st March 1832 was not introduced, with the coming into operation of the present law ; however, this extension of the patent to Crown lands, in which the ordinance of 31st March 1832 was not introduced, cannot be prejudicial to those parties, who have already really made use there of the patented discovery, invention, or improvement before the publication of this extension.
§ 52.
The actual attainment on the part of the proprietor of a patent issued according to the law of the year 1832 of the extended limits of it cannot, however, take place before he has sufficiently established his ownership of it at the highest political jurisdiction of the Crown land in which he desires to enter upon the enjoyment of the patent-rights, nor before the official publication of the patent has been made by the authorities there.
§53.
The extension of the limits of a patent is declared free of every additional payment of fees.
§ 54.
All petitions for the extension of a patent issued in accordance with the law of 31st March 1832 are subject to the provisions of the present one, as soon as it has come into operation.
§ 55.
The infringements of and encroachments on a patent committed before the present law has come into operation are to be treated in those Crown lands in which the patent law of 31st March 1832 was in force, according to the provisions of it.
§ 56.
Immediately after it has come into operation, the present law is at once available generally, subject to the limitations for all matters described in the preceding paragraphs which arise out of previously granted patents, whether they relate to their use, duration, transfer, validity, or suspension, in the stead of the patent law of 31st March 1832, hitherto in force.
The registrations of patents granted or extended before the present law comes into operation remain, however, unaffected thereby.
