MEMORANDUM AND ORDER

WEBBER, District Judge.

Before the Court is Plaintiff Monsanto's Motion for Summary Judgment of Inequitable Conduct [doc. # 143]. For the following reasons, that motion is granted.

1. Procedural Background

Plaintiff Monsanto Company has sought a declaration that its Mon810 YieldGard® corn products do not infringe the claims of four United States patents owned by Defendant Bayer Bioscience [1]—U.S. Patent Numbers 5,254,799 (the '799 patent); 5,545,565 (the '565 patent); 5,767,372 (the '372 patent); and 6,107,546 (the '546 patent). Bayer counterclaimed, arguing that Monsanto infringed claims 1-5 of the '799 patent; claims 1-8 and 12 of the '565 patent; claims 1-5, 13, and 18 of the '372 patent; and claims 1-7 of the '546 patent. This Court held a Markman hearing and construed the disputed patent claims.

Shortly after issuing the order construing certain terms of the asserted claims, this Court granted—in Monsanto's favor— summary judgment of non-infringement of the '799 patent, the '565 patent, and claim 4 of the '372 patent, and summary judgment of invalidity of the '546 patent and claims 13 and 18 of the '372 patent. The only remaining claims for the Court's consideration, then, are claims 1-3 and 5 of the '372 patent. Monsanto now moves for summary judgment that these remaining claims are unenforceable due to Bayer's inequitable conduct in prosecuting their original patent application.[2]

II. Facts

A. Prosecution History of the '799 patent

This motion revolves around the prosecution history of what is now United *854 States Patent No. 5,254,799.[3] In the PTO's first substantive office action on the patent, they considered and rejected claims 240-323 of the original serial no. 06/821,582, as well as claims 387-390 that Bayer added as an amendment. All of the claims depended on claim 240, which claimed:

A plant which includes in its cells [sic] genome and expresses a chimeric gene comprising:
(a) a DNA fragment comprising a promoter region derived from a gene which is naturally expressed in a plant cell; and
(b) at least one DNA fragment coding for a polypeptide toxin produced by Bacillus thuringiensis or having substantial sequence homology thereto.

Prosecution History of '799 patent, JM-6, at 280[4]

The PTO rejected these claims, because, among other reasons, the inventor's disclosure was enabling only for claims limited in accordance with the teachings of the specification with regard to the Bt2 crystal protein polypeptide toxin of the berliner 1715 strain of Bt.[5] The examiner thought the inventors' broad claim of any polypeptide toxin produced by Bt was inappropriate.

Bayer then cancelled the rejected claims, and replaced them with claims 391-410.[6] The dominant one was claim 391, which read:

A plant cell, the genome of which contains a chimeric gene comprising:
(a) a first DNA fragment that encodes a Bacillus thuringiensis insecticidal crystal protein which has been truncated towards a trypsin cleavage site of the protein; and
(b) a promoter region and a 3' nontranslated region containing a polyadenylation signal; the first DNA fragment being under the control of the promoter region; the promoter and 3' non-translated regions allowing the first DNA fragment to be expressed in the ceil;
(c) whereby the chimeric gene can be expressed in the cell as an insecticidal Bacillus thuringiensis polypeptide toxin.

JM-6 at 406.

The Patent office still found several problems with the broad scope of the claim. Noting that the inventors has exemplified the successful use of only the Bt2 crystal protein toxin gene, and that the inventors gave insufficient guidance on how to extrapolate their methods to all Bt genes, the examiner rejected the claims, and insisted that Bayer limit them to the use of the Bt2 gene alone.[7] The PTO also renewed its objection that the inventors' disclosure was enabling only for the berliner 1715 strain of Bt.[8]

On July 23, 1990, the inventors filed a preliminary amendment cancelling claims 392, 393 and 397, and adding claims 411-431. Dominant claim 411 was the same as *855 claim 391, except that in subparagraph (a), it added the limitation that the first DNA fragment had to encode a polypeptide having a molecular weight of approximately 60-80 kD.[9]

The PTO again rejected all of the pending claims in April of 1991. As with all previous rejections, the PTO emphasized that the inventors had not enabled their claimed invention for all Bt crystal proteins.[10] The examiner noted in the rejection that not only were there different varieties of Bt that had numerous insecticidal proteins with varying homology to one another, but the same variety of Bt might have several insecticidal proteins.[11] He further found that the disclosure was "enabling only for claims limited in accordance with the teachings of the specification" with regard to the Bt2 berliner 1715 crystal protein gene where the insecticide encoding fragment is the insecticide coding fragment found in any of pnos Bt2, pssu-Tp-Bt2, pGS1110, pGS1151, and the plant or plant cell is tobacco, and the toxic activity is directed against Manduca sexta or P. brassicae.[12] The examiner even expressed his desire that the inventors specify the particular Bt crystal protein claimed.[13]

Around the time of the April 1991 PTO rejection, Dr. Marnix Peferoen ran Bayer's insect control group, with Mr. Stefan Jansens in charge of entomology, Dr. Marc Cornelissen in charge of Bacillus thuringiensis (Bt) expression, Dr. Arlette Reynaerts in charge of Bt plants, and Dr. Johan Cardoen in charge of Bt patents. This group met regularly to discuss the progress of the various parts of Bayer's Bt project. On June 11, 1991, Dr. Cardoen wrote a memo to the insect control group, and referred to the PTO's latest rejection of Bayer's patent claims. Dr. Cardoen wrote, in part:

We received Office Action from the U.S. PTO. It appears that we are back to square 1. The examiner urges us to limit our claims to the Bt2 gene and tobacco. An interview with the examiner will be necessary; in my opinion we could obtain fairly soon claims on plants containing Bt2-like genes; in order to obtain broader claims we will have to go in appeal (this will probably take 2 years).
