Before LOURIE, BRYSON, and LINN, Circuit Judges.
LOURIE, Circuit Judge .
North American Container, Inc. ("NAC") appeals from the decision of the United States District Court for the Northern District of Texas granting summary judgment of noninfringement in favor of Plastipak Packaging, Inc. and other similarly situated manufacturers and distributors of blow-molded plastic bottles (collectively "Plastipak") of United States Reissue Patent 36,639 ("the '639 patent"). N. Am. Container, Inc. v. Plastipak Packing Inc., No. 3:99-CV-1749-L (N.D. Tex. Nov. 28, 2003) (" Summary Judgment "). NAC also appeals from the district court's decision granting summary judgment that reissue claims 29-42 of the '639 patent are invalid for violating the rule against recapture of previously surrendered subject matter. Plastipak cross-appeals from the district court's decision granting summary judgment that the '639 patent is not invalid for anticipation by U.S. Patent 4,335,821 to Collette. Because we agree with the district court's construction of the claim limitation "generally convex," we affirm the summary judgment of noninfringement for all accused bottles found not to meet that limitation. We further affirm the summary judgment of invalidity of reissue claims 29-42. Because we modify, however, the district court's construction of the claim limitation "reentrant portion," we vacate the summary judgment of noninfringement for all accused bottles found not to meet only that limitation, and remand for the court to determine whether the limitation is met based on our modified claim construction. The cross-appeal is dismissed.
I. The '639 Patent
The '639 patent, entitled "Plastic Container," was reissued on April 4, 2000, in the name of Aziz A. Okhai as inventor, and appellant NAC as assignee. The patent specification discloses a one-piece plastic bottle which improves resistance to creep and other forms of deformation by controlling (1) the presence of unoriented polymer chains in the base portion of the bottle and (2) the thickness of the walls of the reentrant portion. '639 Patent, col. 7, ll. 34-40. These improvements also allow the patented bottle to be manufactured with less material than otherwise, thus lowering its production costs. Id.
The one-piece bottles disclosed in the specification are manufactured by blow molding. Blow molding is a process whereby an injection-molded preform is placed in a mold of the desired finished bottle shape. The preform, which is much smaller than the finished bottle, is shaped like a laboratory test tube. The preform is heated and stretched with a stretch-rod until the bottom surface of the preform touches the bottom surface of the mold. Pressurized gas is then injected into the hot preform so that it expands and takes the shape of the mold when it cools.
A shortcoming of pre-existing blow-molded bottles is that a carbonated beverage contained within the bottle can create sufficient internal pressure to distort, or even fracture, the base portion. Id. , col. 1, ll. 52-59. The susceptibility to failure in the base portion of these bottles is inherent in blow molding, where the bottom surface of the preform is stretched and comes into contact with the bottom surface of the mold. I Once the bottom surface of the preform comes into contact with the mold, the polymer chains in that portion become "frozen" in an unoriented state. Id. Unoriented polymer chains are generally weaker than oriented chains. Id. Moreover, the transition from portions of the bottle having unoriented material to portions having oriented material is relatively abrupt in pre-existing bottles, further creating weak points and making the base portion susceptible to stress cracking. Id. , col. 1, ll. 59-62.
The invention addresses these shortcomings by controlling the distribution of unoriented material in the base portion and by introducing more material into the reentrant portion. Id. , col. 4, ll. 29-31. Shown in figure 2, in its most basic form, the patented bottle is composed of a cylindrical side wall (11), an upper neck portion, and a base portion (12). Id. , col. 3, ll. 5-9. The base portion is further composed of convex semicircular portions (14, 16) extending downwardly from the side wall and converging at the mid-point of the base to form a cusp (18). Id. , col. 3, ll. 9-14. The embodiment in figure 2 improves upon pre-existing bottles by limiting the amount of unoriented material in the base portion to only that at the point of the cusp (18). Id. , col. 3, ll. 21-25.
The specification further teaches that the base portion can be strengthened by truncating the cusp (18), as shown by the dotted line (78). By truncating the cusp, the sides of the re-entrant portion diverge at a relatively large angle and improve the bottle's resistance to deformation. Id. , col. 4, 31-34. Moreover, truncating the cusp strengthens the bottle by making the walls of the re-entrant portion thicker.1 Id. , col. 4, ll. 15-20. Finally, molding the bottle to have a truncated re-entrant portion creates an area of unoriented, relatively thick material that provides a gradual transition between unoriented and oriented material. Id. , col. 4, l. 66 to col. 5, l. 2. This, in turn, improves the base portion's resistance to stress cracking. Id. , col...
