U.S. Circuit Court for the District of Eastern Louisiana·Decided April 18, 1891·Published·Cited by 3 cases

Opinion

Per Curtam.

The complainant has brought suit against the Louisiana Electric light Company for infringement of patent 219,208, which was granted to Charles F. Brush, September 2, 1879, for certain new and useful improvements in electric lamps; the improvements consisting in a device for burning two pairs of carbons successively in one lamp by automatically transferring the luminous arc from the pair first lighted when burned out to a second and fresh pair. The lamp, with the improvement, is known as the “Double Carbon Lamp,” and is in nearly -universal use for all-night lighting of streets and public places. A single pair of carbons will last only about seven hours. By the use of the patented improvement light is maintained throughout the night without renewing the carbons, as would otherwise bo necessary. The case now comes before the court in a motion for preliminary injunction, and shows [894] that the Brush Electric Company., having acquired from Charles P. Brush the exclusive license and control to the patent aforesaid under a contract which gave it the sole and exclusive right to manufacture, sell, rent, use, or otherwise dispose of the apparatus described, in and covered by said patent throughout the whole of the United States, executed to the complainant an exclusive license and right to rent, sell, and use the invention in the state of Louisiana; that the defendant has infringed the said patent; that the Brush Electric Company has become hostile to the complainant, and declines to join in the action, and is therefore made a defendant. The Brush Electric Company is an Ohio corporation. It has not been served with process in this cause, nor does it appear. The patent has been sustained upon final hearing in the sixth and seventh circuits, and preliminary injunctions against infringers have been granted in several cases not yet heard upon the merits. The Louisiana Electric Light Company, the only defendant before the court, does not contest the validity of the patent, nor deny the infringement charged. It, however, opposes the granting of the preliminary injunction asked for.

1. It is urged that the necessary parties are not before the court to authorize the granting of an injunction. It is contended (a) that the complainant-is a mere licensee, and cannot maintain a suit for infringement unless the owner of the patent is joined as complainant, or at least is before the court; and (6) that the license given by the Brush Electric Company to the complainant has been revoked and annulled, according to the terms thereof, by the parent company, and the complainant no longer has any rights whatever in the patent.

2. It is urged that the injunction should not be issued because of the inconvenience to the public necessarily resulting, and the hardship thereby unnecessarily imposed upon the defendant company, the patented improvement being but a trifling part of the costly machinery composing a large and extensive plant.

3. It is said that the injunction should not issue because the complainant has been guilty of laches in asserting its rights.
