Opinion

ORDER

CAMP, District Judge.

This order addresses a motion by The Quikrete Companies, Inc. [“Quikrete”] for judgment as a matter of law or for a new trial and for expedited consideration [# 166 in 89-CV-1177, # 254 in 88-CV-1080]; and a motion for a protective order [184/271]. This order also concerns motions by Nomix Corporation [“Nomix”] for prejudgment interest [162/250]; for enhanced damages and attorney’s fees [163/251]; for a permanent injunction [165/253]; for an accounting of infringing sales [167/255]; and for expedited consideration [173/261]; and a Nomix itemization of costs [174/262],

This opinion addresses one issue raised by Quikrete’s motion for judgment as a matter of law: whether Nomix’s conduct before the Patent and Trademark Office [“PTO”] rendered the patents in suit unenforceable. Because the Court concludes that it did, the Court GRANTS Quikrete’s motion. The Court has carefully considered but does not here address Quikrete’s many other arguments.

Background

This case involves composition and use patents for a type of concrete.

1. Concrete in general

Concrete is a combination of cement and coarse aggregate, either sand, gravel, or crushed stone. Cement is a composition of ingredients such as lime and gypsum that gels into a solid mass in the presence of water. Adding coarse aggregate makes this mass harder and less brittle, and thus better suited for most uses.

The typical way to make concrete is to mix the cement and aggregate, and then combine this dry “cementitious compound” with water shortly before use. The user then pours this hydrated mixture into a hole or mold or onto a surface, where it hardens.

2. Babcock’s invention

In the mid-1980’s, H. Nash Babcock, an engineer and inventor, began trying to develop a special type of concrete mix. His goal was to create a cementitious compound and method of using it that would not require mixing with water before being poured.

In March, 1986, Babcock and a co-inventor filed patent applications with the PTO, assigning their rights to Nomix. These applications concerned special fast-setting formulations of dry cementitious compounds that the user could simply pour into water, and that would then cure into usable concrete without any mixing.

Nomix encountered some difficulty getting its patents approved. In October, 1986, and *1365 again in March, 1987, an examiner rejected Nomix’s initial applications for the patents in this suit as obvious under 35 U.S.C. § 103. Nomix amended its applications and persisted.

3.The Kutach rejection

Meanwhile, Nomix was pursuing another related patent application, involving pouring dry concrete mix into a mold (rather than a hole) filled with water. In January, 1986, one Examiner Kutach preliminarily rejected this application. In part, she based her decision on the Lake Patent, No. 743,525 (issued Nov. 10, 1903).

The Lake Patent discloses a process for making artificial stone out of concrete. This process involves pouring dry cement mix into a lubricated mold containing water. As the mixture is poured in, the water rises along the mold’s sides. In the end, about half an inch of water remains on top. This process does not involve any separate mixing. Wrote Kutach,

Lake teaches the basic process as claimed by applicant in which a dry cementitious mixture is fed to a mold after the mold has been previously filled with an excess of water needed for the hydration of the cem-entitious mixture without any type of physical mixing of the cementitious mixture with the water. With respect to the proportions of materials forming the cementi-tious mixture, Lake teaches having from five parts stone or sand mixed with one part cement to one part stone or sand mixed with five parts cement. Therefore, applicant’s claimed proportions of cement binder are well within the purview of Lake. The secondary references are cited to show that it is generally well known and conventional in the art to provide the various particles of cementitious mixture with similar characteristics such that the various particles do not separate from each other when being added to water.
Pl.Exh. 20 (1/27/88 office action at 4).

Nomix sent Kutach a response. 1 But No-mix did not mention the Lake Patent to the other examiners reviewing Nomix’s other applications.

4. The patents

In March and May, 1988, the PTO issued the patents involved in this suit. Patent No. 4,747,878 [the “’878 patent”] claims various cementitious compositions, and Patents No. 4,732,781 [the “ ’781 patent”] and No. 4,732,-782 [the “’782 patent”] claim methods for using these compositions.

Essentially, these patents involve mixtures of “finely divided particles” containing at least 20 percent by weight of cement binder. The “major portion” of these particles must have “approximately the same drop rate”, so that the material does not segregate—i.e., divide up with the heavy aggregate at the bottom and the lighter cement at the top— when poured through water.

The claimed mix must also contain compounds that will allow it to absorb at least 50 percent of its own volume of water. One uses this invention by first “saturating a substrate with water in substantial excess of that needed for hydration”, and then pouring in the dry mix.

In a section describing the invention’s background, these patents each declare,

At present, it is essential that all cementi-tious compositions are mixed with water before placement in order to obtain the proper characteristics of the final product. Some type of mixing is and has always been required.... Cementitious mixtures could not be placed in a dry state directly into water or on to a wet surface without first wetting and mixing the dry ingredients.

This was Nomix’s position throughout the application process.

5. The dispute with Quikrete

Nomix began marketing its inventions before these patents issued. In March, 1987, Nomix introduced a packaged dry mix called “PostSet” at a Chicago trade show. Nomix intended this product to help homeowners and others set fence posts without mixing. Among those attending the show were execu *1366 tives of Quikrete, an Atlanta-based manufacturer and licenser of packaged cement.

Quikrete developed a product that competed with Po'stSet, which Quikrete called Fast Setting Concrete [“QFSC”] and originally-sold in a red bag.

In March, 1988, Nomix sent letters to Qui-krete manufacturers and other in the trade to notify them that the PTO would soon issue the first of Nomix’s patents. These letters warned, “We are ready and willing to license you to manufacture our patented PostSet product, but we must also protect our patents ....
