Before MARKEY, Chief Judge, and DAVIS and BISSELL, Circuit Judges.
Hi-Life Products, Inc. (Hi-Life) appeals from that portion of a final judgment of the United States District Court for the Central District of California providing that "[n]one of [American National Water-Mattress Corp.'s (AM-NAT) ] waterbeds infringe [sic] [Hi-Life's United States Letters] Patent No. 4,411,033...." See Hi-Life Prods., Inc. v. American Nat'l Water-Mattress Corp., 2 USPQ2d 1886 (1987) (). We vacate and remand.
The 4,411,033 ('033) patent describes and claims a waterbed mattress containing a wave dampening structure made from an insert of open cell foam that has a material of low specific gravity disposed throughout its body. The open cells in the foam trap and restrict the movement of the water, thereby dampening excessive wave motion. To be effective in dampening the waves, the foam body must float at the top of the container. The inventor discovered and disclosed in the '033 patent that by adding a lightweight material to the foam slab, the resulting structure would float and provide excellent wave dampening characteristics.
The '033 patent, assigned to United Foam Corporation (UFC), issued October 5, 1983. UFC filed for bankruptcy in 1986. AM-NAT and Hi-Life both submitted bids for UFC's assets, which included the '033 patent. Hi-Life was the successful bidder, but even before the transfer of the assets to Hi-Life was completed, AM-NAT commenced marketing a waterbed mattress similar to the waterbed mattress disclosed in the '033 patent.
Shortly thereafter, Hi-Life filed suit against AM-NAT, alleging, inter alia, infringement of the '033 patent. Both parties filed motions for partial summary judgment on the issue of infringement. In a March 31, 1987 order, the district court granted AM-NAT's motion for partial summary judgment of noninfringement and denied Hi-Life's cross-motion. In that order the district court found that the accused devices did not literally infringe the '033 patent. The court, in addressing the issue of infringement under the doctrine of equivalents, reasoned that prosecution history estoppel precluded application of the doctrine. After the district court allowed both parties to dismiss the remaining issues without prejudice, final judgment of noninfringement was entered on July 30, 1987.
1. Whether the district court clearly erred in finding that the accused waterbed mattresses did not literally infringe the '033 patent.
2. Whether the district court erred in holding that Hi-Life was estopped from contending that the accused waterbed mattresses
infringed the '033 patent under the doctrine of equivalents.
OPINIONSummary judgment is appropriate when there is no genuine issue of material fact and the moving party is entitled to judgment as a matter of law. Fed.R.Civ.P. 56; SRI Int'l v. Matsushita Elec. Corp. of Am., 775 F.2d 1107, 1116, 227 USPQ 577, 581 (Fed.Cir.1985) (in banc). "[T]he district court must view the evidence in a light most favorable to the nonmovant and draw all reasonable inferences in its favor and must resolve all doubt over factual issues in favor of the party opposing summary judgment." Id. (citations omitted).
On appeal, Hi-Life argues that AM-NAT's waterbed mattresses literally infringe claims 1, 12, 16 and 21-28. Literal infringement requires that the accused waterbed mattresses embody every limitation of the asserted claims. Builders Concrete, Inc. v. Bremerton Concrete Prods. Co., 757 F.2d 255, 257, 225 USPQ 240, 241 (Fed.Cir.1985). Here, the district court correctly determined that AM-NAT's waterbed mattresses did not literally infringe the claims of the '033 patent because the open cell foam insert did not have a material of low specific gravity disposed throughout its body. Instead, AM-NAT's foam insert floats because a sheet of low specific gravity material is attached to the bottom surface of the foam body. Hi-Life, 2 USPQ2d at 1887. After reviewing the record and carefully considering Hi-Life's arguments with all reasonable inferences drawn in its favor, we agree with the district court's decision on the issue of literal infringement.
The district court never reached the issue of infringement under the doctrine of equivalents. Instead, it concluded as a matter of law that Hi-Life was estopped from contending that AM-NAT's waterbeds infringe under the doctrine of equivalents because the claims were rejected by the patent examiner as unpatentable until amended to describe a material of low specific gravity disposed throughout the body of the foam. Id. We disagree.
The doctrine of prosecution history estoppel precludes a patentee from asserting equivalents that would resurrect subject matter given up during prosecution to overcome rejections based on prior art. Hughes Aircraft Co. v. United States, 717 F.2d 1351, 1362, 219 USPQ 473, 481 (Fed.Cir.1983). When the doctrine "is invoked, a close examination must be made as to, not only what was surrendered, but also the reason for such a surrender." Bayer Aktiengesellschaft v. Duphar Int'l Research B.V., 738 F.2d 1237, 1243, 222 USPQ 649, 653 (Fed.Cir.1984). At issue here are the equivalents that the patentee gave up by adopting the examiner's proposed amendment. We have rejected the view that all amendments to claims operate as an estoppel in finding infringement under the doctrine of equivalents:
Amendment of claims is a common practice in prosecution of patent applications. No reason or warrant exists for limiting application of the doctrine of equivalents to those comparatively few claims allowed exactly as originally filed and never amended. Amendments may be of different types and may...
