SWYGERT, Circuit Judge
(concurring).
I concur in Judge Duffy’s opinion. However, I feel that I must state my understanding of Crane Packing Company v. Spitfire Tool and Machine Company, 7 Cir., 276 F.2d 271, and how it relates to the issue presented by the motion for summary judgment in the present case.
According to my understanding of Spitfire, the reissue claims were directed to an inventive concept different than was encompassed by the original claims thereby making them subject to 35 U.S.C. § 102(b). Consequently, I think that when the District Court hears the case on its merits, a determination is required whether the disputed reissue claims are merely a broadening — a “filling out”— of the original claims within the limits of the alleged invention or are directed to a different invention and therefore come within the ambit of Muncie Gear Works, Inc. v. Outboard, Marine & Mfg. Co., 315 U.S. 759, 62 S.Ct. 100, 86 L.Ed. 479, and Engineering Development Laboratories v. Radio Corporation of America, 2 Cir., 153 F.2d 523.
