 436 FBDBHAL REPORTEE. �«xpired by limitation or operation of law on or before January 6, 1875. �We have been furnished with a copy of the Prench patent in the French language, in manuscript, duly authenticated by the proper authority in Paris, and with what purports to be a translation of it. The French law concerning patents, which was in force when the transactions took place in France, in respect to said French patent, was that promulgated July 8, 1844. Under that law patents are granted for five, ten, or fifteen years, aocording to the tax paid. �Whoever wishes to take ont a patent for an invention must deposit, under seal, at the office of the secretary of the prefecture, in a speoi- fied department, a petition, with a description of the invention, and necessary designs or patterns, and a list of the pieces deposited. The patent begins to run from the time of such deposit. Within five days after such deposit, the prefect transmits all the pieces deposited to the minister of agriculture and commerce. There they are opened, and the petition is enrolled. If the application is regular, a decree of the minister is delivered to the applicant, and constitutes the pat- ent. To such a decree a duplicate of the description and designs are annexed. The patentee, during the duration of the patent, has a right to make additions, under the same regulations as to deposit of a petition, etc. A certificate of addition is delivered in the same form as the original patent, and has, from the dates of the demand and grant, respectively, the same effect as the principal patent, with which it expires. If a patentee wishes to take out a patent for five, ten, or fifteen years, for an addition, instead of a certificate of addi- tion expiring with the original patent, he must', besides the same for- malities, pay a new tax, as on an original patent. In the French patent under consideration there is first a patent granted to Bouvet for 15 years, and dated November 30, 1861, with a description and a drawing annexed, referred to in the description. The text shows that the patent was "taken" November 30, 1861. �The decree or grant appears to have been made by the minister January 35, 1862. Next, there is a certificate of an addition by Bouvet, of the date of December 21, 1861, to the patent of Novem- ber 30, 1861, with a description and a drawing annexed. The text shows that the certificate of addition was "taken" December 21, 1861. The certificate appears to have been made by the minister, February 27, 1802. Next, there is a certificate of an addition by Bouvet, of the date of November 27, 1862, to the patent of November 30, 1861, with ��� �
