Before MARKEY, Chief Judge, and FRIEDMAN and DAVIS, Circuit Judges.*

FRIEDMAN, Circuit Judge.

DECISION

The judgment of the United States District Court for the Western District of Texas, dismissing all eight counts of the appellants' complaint, including two counts of patent infringement, is affirmed.

OPINION

* Hydroxylapatite is a naturally-occurring mineral and is the major mineral component of human teeth and bones. United States Patent No. 4,097,935 (the '935 patent), which is assigned to the appellant Sterling Drug Inc., discloses a ceramic hydroxylapatite composition, and the process for making the ceramic, which is used in dentistry and orthopedics. United States Patent No. 4,551,135 (the '135 patent), also assigned to Sterling Drug Inc., discloses a syringe for mixing and extruding a plasticizable mixture such as the ceramic hydroxylapatite.

Dr. Jarcho, the named inventor on the '935 patent, worked for Sterling Drug Inc., from 1969 to 1979, when he left to join the appellee Carbomedics, Inc., and later joined the appellee Intermedics, Inc. Appellants Sterling Drug Inc. and its wholly owned subsidiary Cooke-Waite Laboratories, Inc. (hereinafter Sterling) filed a complaint alleging misappropriation of trade secrets relating to hydroxylapatite, misrepresentation in advertising in violation of section 43(a) of the Lanham Act, breach and inducing the breach of Dr. Jarcho's employment contract with Sterling Drug, tortious interference with Sterling Drug's current and prospective contractual relations, unfair competition, unjust enrichment, and infringement of the '935 and '135 patents. The appellees counterclaimed for a declaratory judgment of patent invalidity, noninfringement and unenforceability.

Following a jury trial, the jury answered special interrogatories in which it ruled for the appellees on the nonpatent claims and determined that the '935 patent was valid but not infringed and that the '135 syringe patent was invalid and not infringed. We affirm these determinations, except that we find it unnecessary to consider whether the '135 patent was infringed.

II

The appellants mount a shotgun attack on the district court's decision, asserting 25 separate grounds (contained in nine separate points in their opening brief) upon which the district court allegedly erred. Many of the contentions involve an attempt to retry the case in this court. We reject those contentions because the jury's factual determinations that the appellants challenge are supported by substantial evidence. The other rulings of the district court that the appellants challenge either were legally correct or involved a proper exercise of the court's discretion.

A. The district court correctly denied the appellants' motion for judgment n.o.v. or for a new trial on the patent infringement, trade secret misappropriation, breach of contract, Lanham Act, and unfair competition claims.

1. a. The '935 Patent. Sterling argues that it proved literal infringement of the '935 patent by its expert testimony and that the appellees presented no "substantial evidence of non-infringement." The burden was on Sterling to prove infringement; the accused infringer is not required to prove non-infringement. Stratoflex, Inc. v. Aeroquip Corp., 713 F.2d 1530, 218 USPQ 871 (Fed.Cir.1983).

The evidence on infringement was in conflict. There was evidence that could have led the jury to reject the appellants' expert testimony on credibility grounds. The appellees presented evidence that their product and process did not fall within the claims of the '935 patent. That evidence included testimony that the accused process did not produce a gelatinous precipitate, and that the resultant product did not have the claimed density and was actually produced by the prior art techniques. We cannot say that the jury's determination of non-infringement was without substantial evidentiary support or that the district court abused its discretion in denying a new trial on the patent infringement issues.

Sterling challenges the district court's application of prosecution history estoppel to bar a finding of infringement under the doctrine of equivalents. During prosecution of the '935 patent, the term "gelatinous" was added to distinguish the precipitate in the "Jarcho process from similar processes where material was powdered prior to sintering or powdered and compacted prior to sintering." Sterling Drug Inc. v. Intermedics Inc., 3 USPQ2d 1467, 1469 (W.D.Tex.1987). As the district court stated:

The inclusion of the recitation "heating said gelatinous precipitate" was crucial to obtaining the allowance of all the process claims. The prosecution shows that the meaning Sterling ascribed to this phrase at that time was one of initially producing a cohesive gel material by precipitation and then sintering the material while it remains in that cohesive state.

Id. The court found that the '935 product claims

were allowed over the prior art only after: 1) the claims were amended to limit the density to "a density greater than approximately 98 percent of the theoretical density of hydroxylapatite and being further characterized by the absence of pores," 2) the personal interview at which the Examiner was shown photomicrographs illustrating the total absence of pores in the ceramic material, and 3) receipt of the Jarcho articles which emphasized the pore-free nature of the Jarcho ceramic.

Id. at 1470.

The district court justifiably concluded that these limitations were critical to the issuance of the '935 patent and preclude a finding that the appellees infringed under the doctrine of equivalents.

b. The '135 Patent. The jury determined that claims 1 and 35 of the '135 patent were anticipated and that claims 2, 3, 31, 32, and 33 would have been obvious. Claims 1 and 31 are the only independent claims in issue. The district court did not err in denying Sterling's motion for judgment n.o.v. on the validity of the '135 patent.

Sterling argues that the jury's determination that claim 35 was anticipated cannot stand because claim 35 is dependent upon claim 33, which was found to be obvious. It relies upon RCA Corp. v. Applied Digital Data Systems, Inc., 730 F.2d 1440, 1446, 221 USPQ 385, 389 (Fed.Cir.), cert.
