This suit was brought for the infringement of patents for mechanisms for pressing and blowing glassware.
It was originally brought against the Simonds Manufacturing Company and Biddle Arthurs, president, and John J. Power, under the following patents: No. 416,389, to Windmill, December 3, 1889, for molds for glass bottles, etc.; No. 416,376, to Rylands, December 3, 1889, for machinery for manufacture of bottles; No. 531,609, to Blue, December 25, 1894, for molds for the manufacture of glassware; No. 567,071, to Blue, September 1, 1896, for machines for manufacturing glass bottles. During the taking of the opening testimony, complainant and appellant announced that he would not ask relief under either of the patents to O. E. Bine, Nos. 531,609 and 567,071, so that the suit is limited to the Windmill and the Rylands patents, of which complainant duly became assignee.
Section 25 of the act of congress of July 8, 1870, as embodied in ■ section 4887, Rev. St., is as follows:
“No person shall be debarred from receiving a patent for his invention or discovery, nor shall any patent be declared invalid, by reason of its having been first patented or caused to be patented in a foreign country, unless the same has been introduced into public use in the United States for more than two years prior to the application. But every patent granted for an invention which has been previously patented in a foreign country shall be so limited as to expire at the same time with the foreign patent, or, if there be more than one, at the same time with the one having the shortest term, and in no case shall it be in force more than seventeen years.”
The earliest legislation on the subject of foreign patents is found in section 8 of the act of 1836, where, for the first time, it was provided that nothing in the patent act then enacted should be—
“Construed to deprive an original and true inventor of the right to a patent for his invention, by reason of having previously taken out letters therefor in*645 a foreign country, tlio same having been published any time within sis months next preceding the filing of his specifications and drawings.”
By section 6 of tbe act of 1839 two other conditions were made, as follows:
“Provided that the same shall not have been introduced into public and common use in the United States, prior to the application for such patent; and provided, also, that in all cases, every such patent shall be limited to the term of fourteen years from the date or publication of such foreign letters patent."
This was the state of the law when the act of 1870 was passed, the twenty-fifth section of which became section 4887, Rev. St., as above quoted. It will be observed that this section, while it extended the right of a foreign inventor and patentee, as it existed under the acts of 1836 and 1839, in regard to the limitation by a two-years public use, on the other hand, changed, in the interest of the American public, the term for which such foreign patentee could obtain a patent in the United States from 14 years from the date of the foreign patent to a period to be measured by the shortest term of the foreign patents previously obtained. This limitation of tbe term of the monopoly of an American patent, where the pat-entee has previously obtained a foreign patent, is obviously in the interest of those from -whom tribute is exácted by such monopoly,: and this purpose to do justice to the American public, by giving them the same privilege as is accorded to the people of the foreign country in which the patent is first granted, challenges the consideration of the court. Certified and legalized copies of these two Danish patents or enerets were offered in evidence, and no objection can be raised to the sufficiency of the proof of their being what they purported to be. Translations of the patents were also offered, and appear in the record. The first one, granted October 1, 1889, is as follows:
“Wo, Christian the Ninth,” etc., “make known that wo. in accordance with the application and request for the same, most submissively made, along with the circumstances brought out on tho occasion, most graciously have allowed and granted, and herewith allow and grant, that Dan Hylands, of Barnsley, In England, may, for a period of 7 years, to reckon from this day, have the exclusive right everywhere in Denmark, with exception of the Faroes, Iceland, and colonies, to make and allow to make machines for molding glass bottles by pressing and blowing, indicated by him in the description hereto appended, with two drawings belonging thereto, of which the counterpart is furnished to our minister of the interior on condition that he, within two years, to be reckoned from the date of tills, our allowance, here in the kingdom, has brought tlie Invention named to execution and later combines [continues?] with it. Meanwhile this exclusive right will be lost, in so far as it shall be proved that any one else previously here in the kingdom has made or allowed to be made machines of the properties in question. Forbidding all and every one to make hindrance against what has been prescribed.
“Given at Fredensborg, October 1st, 1889. Christian, K.
“Allowance of exclusive right for Dan Bylands, of Barnsley, in England, for machines for molding glass bottles by pressing and blowing.”
Then follows what corresponds to the specifications and claim of an American patent, under the heading, “Description of Improvements in Machines for Molding Grlass Bottles by Both Pressing and Blowing.” The other patent or eneret, granted November 1, 1889, is in the same form, and need not be reproduced.
That there was no patent law, in the sense of a legislative enactment, in Denmark, until 1894, does not affect the situation. Prior to the enactment of the law of that year, patents or enerets were granted and issued by the king, in exercise of the royal prerogative, and the term for" which they were granted was determined according to what seemed the exigency of each case. Nevertheless such patents were issued by virtue of the recognized lawful authority vested in the reigning monarch, and were acts of sovereignty as completely as were legislative enactments. ITow the sovereign authority of a country shall speak in a given case depends upon the constitution and settled scheme of government of that country. In Great Britain, ns probably in other monarchical countries, patents for inventions have always been the subject of royal grants. The Danish patent act of 1894 changed the method of procedure and of granting an eneret or patent, although under this act the extent of the monopoly is about the same as it was according to custom and usage under the royal grants.
