I. The Trial

A. PROCEDURAL BACKGROUND

Avco Corporation (“Avco”) brought the first of these two consolidated cases seeking a declaration that United States Patent No. 4,529,467 (“the Ward patent”) issued to PPG Industries, Inc. (“PPG”) was void or invalid on various grounds. PPG brought the second action alleging patent infringement by Avco and claimed a jury trial.

After consolidation, the issues triable as of right to a jury came on for such a trial. At trial, Avco admitted that its product, CHARTER III, infringed certain claims of the Ward patent. The Court directed a verdict for Avco as to the remaining claims of the Ward patent. On the thirteenth day of trial, the remaining issues in the case were submitted to the jury which duly rendered a verdict on July 26, 1993, wholly in favor of *87 PPG. The jury found that Avco Corporation had failed to prove by clear and convincing evidence that the Ward patent was void or invalid on the ground that it was obvious or that it was anticipated by another Avco product, CHARTER 59. It followed ineluctably that the Ward patent was valid and infringed by Avco’s CHARTER III. Indeed, the jury went on to find that Avco had, in fact, willfully infringed the Ward patent and, applying a lost profits analysis, awarded damages of $25,571,824.00. Despite the jury’s finding of willfulness, this Court did not impose any multiplier of damages, nor did this Court impose any attorneys’ fees. Given the size of the jury verdict and its obvious lost profits analysis, this Court was satisfied that PPG would be fully compensated by entering judgment on the jury verdict without a multiplier or attorneys’ fees.

The Court then, see Beacon Theatres, Inc. v. Westover, 359 U.S. 500, 510, 79 S.Ct. 948, 956-57, 3 L.Ed.2d 988 (1959), turned to Aveo’s last ditch defense. Avco contended that the Ward patent was invalid and unenforceable due to the inequitable conduct of PPG in filing and pursuing its patent application. 1 On July 27, 1993, ruling from the bench, this Court rejected the inequitable conduct defense. In setting forth its oral findings and rulings, the Court reserved the right to enter a comprehensive written opinion. This is that opinion.

B. FACTUAL BACKGROUND

To understand Avco’s inequitable conduct defense, one must first understand the marketplace in which the patent at issue finds its commercial expression. The market is comprised of specialized fire protective coatings for large steel structures, primarily offshore drilling rigs and oil refineries. These coatings are designed to retard the buckling and actual consumption by fire of steel structural members for as long as possible when exposed to the extremely high temperatures of an oil fire.

Avco first dominated this market, having successfully developed, marketed, and supplied a product known as CHARTER 59. CHARTER 59 is customarily applied using galvanized mesh to support the fire protective coating. The galvanized mesh contains zinc. CHARTER 59 is not patented, and was generally available on the market. Avco, however, did take some care to keep secret the actual composition of CHARTER 59.

PPG made a considered corporate decision to enter this market. First, PPG reverse engineered CHARTER 59. Mr. Ward, one of the inventors named in the Ward patent, prepared an in-house PPG version of CHARTER 59. This initial composition contained no zinc. In July, 1980, PPG conducted a computer-based prior art search. The Sawko patent, a patent mentioning zinc as a fire-retardant substance, was ordered as a result of this computer search and was placed in Mr. Ward’s personal files. The PPG laboratory also made frequent comparison and reference tests to the commercially competitive product it was imitating, CHARTER 59. Throughout the testing, PPG referred to CHARTER 59 as the control, the product against which PPG intended to measure its own commercial product. PPG called its prototype composition PITT-CHAR.

During the developmental work of PITT-CHAR at PPG, Mr. Ward, or someone acting on his behalf, contacted Dorothy MacFarlane at U.S. Borax and requested a fifty pound sample of FIREBRARE ZB. Ms. MacFar-lane specifically recalled this fifty pound request because most other requests for samples of FIREBRARE ZB were in the one-half to two pound range. Accordingly, Ms. MacFarlane considered PPG to be a hot prospect for FIREBRARE ZB. In filling its request, she also forwarded U.S. Borax bulletin 1281 to PPG. 2

*88 For two years, culminating in September, 1983, Mr. Ward compared and tested PPG’s PITT-CHAR precursor against CHARTER 59 at Underwriters Laboratories (“UL Labs”). In September, 1983, one month pri- or to the Ward patent application filing date, Mr. Ward subjected CHARTER 59 and PPG’s PITT-CHAR to UL Lab’s crucial 1709 rapid rise fire test. The results showed that PPG’s PITT-CHAR product performed comparably to CHARTER 59, with its standard galvanized, i.e. zinc-coated, mesh reinforcement. It was time to seek patent rights.

In submitting the application to the Patent Office on the PITT-CHAR product, Mr. Ward and the other inventors submitted internal PPG documents entitled Memorandum of Invention that referred to data which they considered prior art. Among the internal documents submitted were notes of telephone conversations between Mr. Ward and Linda Pignitore, a patent attorney at PPG.

Mr. Ward disclosed to Ms. Pignitore that CHARTER 59 was an epoxy polyamide composition. He told Ms. Pignitore that CHARTER 59 had been used as his base line and was a product he was trying to trump by the development of PITT-CHAR. In addition, Mr. Ward disclosed to Ms. Pignitore in his Memorandum of Invention certain tests from UL Labs which eventually became Example 9 of the Ward patent.

The notes reveal that Mr. Ward made mention of the commercial universe in which PITT-CHAR was intended to be marketed and the market against which PITT-CHAR was intended to be more effective. Mr. Ward mentioned the competition to be expected from cementitious products and mentioned to Ms. Pignitore the advantages and disadvantages of those products. Mr. Ward specifically mentioned CHARTER 59 to Ms. Pignitore as a commercially viable PITT-CHAR competitor. Mr. Ward thought that PITT-CHAR was patentable because it was a sufficient advance over this competition.

In July, 1984, the Patent Office rejected the Ward patent application as obvious. Even though the patent examiner presumably knew about the Sawko patent 3 which mentions the role of zinc in fire retardation, the primary references relied upon by the patent examiner as prior art epoxy intumescent fire retardant compositions were the Lloyd-Lucas and Matsumoto patents. Significantly, both these patents are devoid of any teaching that zinc is a source of the fire retardant capability of the patent issued.

To overcome the patent application rejection, Mr.
