This suit is for an infringement of the Thompson patent, No. 1,815,745, which was held valid and infringed below as to claims 1, 2, 4, 5, 7, and 8. The patent relates to a sa fefy razor of the Gillette typo, in which is used a thin flexible double-edged blade which is clamped and adjustably flexed between a guard plate and a cap. Blades of this type have been in use for more than twenty years. The razor frame and the double-edged blade have had patent protection under patents which have expired.
The patented razor in this suit differs from the well-known Gillette razor in one respect. The comers of the cap are provided with small reinforcing lugs designed to add rigidity and prevent deformation should the user accidentally drop the cap. The patentee says that, if the cap of an old Gillette razor is dropped, the impact of the blow may affect the metal at the comer and form a little burr which, bearing against the blade, may bend the blade when the razor parts are assembled and, in an extreme case, may crack it. These reinforcing corner lugs are said to avoid this danger and to make the razor more rigid and strong. It therefore became necessary in manufacturing blades to fit this Thompson razor to out notches in the corners of the blade and thereby escape the lugs. The blade otherwise is the old form of Gillette razor blade.
The claims in suit refer to the Gillette type of razor with reinforcing lugs on the comer of its cap and including a blade as one element. There are no claims on the blades per se. The razors are sold by the appellee with a complement of one or more blades having notched comers. Appellee makes no profit on the sale of the razors, but does realize its profit on the sale of the replacement blades. Safety razor blades are short lived, although it is possible to resharpen, them, but most of them are discarded for new blades, avoiding stropping and honing. The appellant does not make the safety razors, but does make the blade. It is charged with contributory infringement, not direct infringement, of appellee’s patent. Appellant’s blades may be used on the Thompson razor.
Aside from the questioned validity of this patent, we think it sufficient to say that the appellant is not chargeable with contributory infringement by manufacturing and selling replacement blades. The appellee has made clear, as the record discloses, that its original idea was to make a razor with blades so cheap that they might be used but once and then, thrown away. It says that the user will always have the cutting edge of his razor blade in the same perfect condition as that of a new blade. It claimed to be the first to produce a razor blade which might be thrown away when dull without the loss of economy. Its advertising matter and information to the trade made all this clear. Moreover, instructions on the blade as to its use read at one time, “no honing or stropping; not to bo resharpened.” The present notched and slotted blades in no way change the cutting edges, and the same policy continued. The more blades the appellee sold, the greater were its profits. To be sure, there is some evidence that some users resharpened their blades and that they lasted for a year, or two, but these were exceptional instances.
If the blades were not merely supplied for use in a patented razor holder but were a nonpatented component of a patented combination, the entire device might be regarded as a patent for a combination with component elements of blade, cap, guard, and mechanism for lightening the cap. and guard together. The blade is mentioned in the descriptions of the claims of the patent, and, although that is not conclusive, since elements patented are always described in relation to their unpatented materials with which they are used whether they are a part of the patent or not, the razor patent extends to a combination including the blade as one of its components.
The rule has long been recognized that unpatented components of a patented combination which wear out quickly, as compared to the life of the combination as a whole, may be replaced without infringement. Heyer v. Duplicator Mfg. Co.,
