judgment may be granted. See Walker v. G. M. Corp., 362 F.2d 56, 59 (9th Cir. 1966), Proler Steel Corp., Inc. v. Luria Brothers and Co., 417 F.2d 272, 273-274 (9th Cir. 1967) and cases cited therein.
(2) THE PATENT CLAIM AND THE APPLICABLE LAW
The patent at issue is directed to a ball-point pen refill unit which comprises a pair of ball-point cartridges detachably connected to one another in tandem or “piggy-back” fashion by a connector element. The connector element joins the two cartridges to form a rigid unit which may be projected and retracted in a conventional pen barrel and readily removed from and inserted into the barrel. The connector also permits ready detachment of the two cartridges so that their positions may be reversed to place either in the writing (lower) position.
In one embodiment, the connector element is a bushing carried in the upper end of each cartridge. The writing end of the other cartridge fits tightly, but removably, into this bushing to form a dual-cartridge unit which may be employed in a conventional bail-point pen barrel. When the lower cartridge is out of ink, the unit may be removed from the barrel and the positions of the cartridges reversed to place the unused upper cartridge in the lower (writing) position. The reassembled unit may then be replaced in the pen barrel and employed until the second cartridge runs dry.
A vent is provided- in each cartridge to permit the feed of ink to the writing tip. Provision of such a vent is required, because the tight fit of the writing tip of the upper cartridge in the bushing in the lower cartridge would otherwise seal the lower cartridge from the atmosphere and inhibit the free flow of ink to its writing tip.
Claims 4-6 of the Ashcroft Patent are directed to this first or “bushing” embodiment shown in Fig. 1 (defendants' Exhibit C). In the second embodiment of the Ashcroft Patent, the connector element is a sleeve which tightly but detachably joins the two cartridges. Claims 1-3 of the Ashcroft Patent are directed to this second or “sleeve” embodiment.
The District Court found that the patent was invalid on three grounds. Because we agree that the claims of the appellants “would have been obvious at the time the invention was made to a person having ordinary skill in the art ”, (35 U.S.C.A. § 103), we affirm the decision below and need not, nor will we, reach the patent’s validity under §§ 101 and 102.
At the outset we note the teachings of Graham et al. v. John Deere Co. of Kansas City, et al., 1965, 383 U.S. 1, 86 S.Ct. 684, 15 L.Ed.2d 545 and Great Atlantic and Pacific Tea Co. v. Supermarket Equipment Co., 1950, 340 U.S. 147, 71 S. Ct. 127, 95 L.Ed. 162, the two more recent Supreme Court decisions on patent validity. This Court extensively discussed the principles announced in these eases in several recent decisions. See Jeddeloh Brothers Sweed Mills, Inc. v. Coe Manufacturing Co., 375 F.2d 85, 87-88 (9th Cir. 1967) and Griffith Rubber Mills v. Hoffar, 313 F.2d 1, 3-4 (9th Cir. 1963). Despite the traditional aversion of American Law to monopoly, exclusive rights to an invention are granted solely as a “reward, an inducement, to bring forth new knowledge. Only inventions and discoveries which furthered human knowledge, and were new and useful, justified the special inducement of a limited private monopoly.” Graham, 383 U.S. at p. 9, 86 S.Ct. at p. 689. The history of the American patent system is replete with the continuing tension between a strong public policy against monopoly and a desire to encourage inventions which will benefit the public. This tension has been resolved by the courts setting a high and exacting standard for patent validity. As we noted in Jeddeloh:*
“The entire tenor of the Graham decision is that there should be strict observance of all three explicit condi
