*999 /. INTRODUCTION AND BACKGROUND

Trial is set to begin in this matter on October 18, 1999, and the case is now before the court pursuant to plaintiff Deth-mers Manufacturing Company’s September 27,1999, and October 12, 1999, motions in limine, and pursuant to defendant Automatic Equipment Manufacturing Company’s October 12, 1999, motion in limine. Courtesy copies of the latter two motions were sent to the court by facsimile transmission on October 8, 1999. At the court’s request, the court also received supplemental letter briefs by facsimile on October 12, 1999. The court heard oral arguments on the motions in limine on October 13, 1999, and finds that the motions are now fully submitted.

At the oral arguments, plaintiff Deth-mers Manufacturing Company, Inc., was represented by David Tank of Davis, Brown, Koehn, Shors & Roberts, P.C., in Des Moines, Iowa, and Brian J. Laurenzo of Dorsey & Whitney, LLP, also in Des Moines, Iowa. Defendant Automatic Equipment Manufacturing Company was represented at the oral arguments by Tim Engler of Harding, Shultz & Downs in Lincoln, Nebraska. The court was impressed not only with the cogency of counsels’ oral arguments, but with the expeditiousness and coherence with which counsel for both parties marshaled authority and facts to address the various issues that arose quite suddenly in the course of final trial preparations. This case has been very contentious, but counsel have been models of civility and professionalism in their presentations to the court. The court has little doubt that this high level of professionalism will continue through trial of this matter.

The parties to this lawsuit are both makers of tow bars used to tow an automobile behind a recreational vehicle (R.V.). The principal claims and counterclaims in this lawsuit originally concerned infringement, validity, and enforceability of the parties’ patents for such tow bars. 1 However, as a result of this court’s rulings on summary judgment motions, see Dethmers Mfg. Co., Inc. v. Automatic Equip. Mfg. Co., 23 F.Supp.2d 974 (N.D.Iowa 1998) (Dethmers I); Dethmers Mfg. Co., Inc. v. Automatic Equip. Mfg. Co., 70 F.Supp.2d 944 (N.D.Iowa 1999) (Dethmers II) (publication pending), no patent claims, and none of Automatic’s counterclaims, remain at issue here. Furthermore, Dethmers noti *1000 fied the court that it was dismissing five of its remaining state-law claims. Thus, the present action is proceeding to trial only on Dethmers’s claims of breach of contract, unjust enrichment, and promissory estoppel.

All of these remaining claims involve the so-called “Parent Invention.” The “Parent Invention” was an idea developed by Richard A. Parent for a new type of tow bar that involved a swivel or universal joint and folding tow bar arms. The tow bar could also be folded up on the back of an R.V. for storage when not in use. All of the remaining claims involve the assertion that Automatic has wrongfully used the “Parent Invention” in the design and manufacture of its tow bars without properly compensating Parent. Dethmers asserts these claims as Parent’s assignee. The court determined in its ruling on the first round of summary judgment motions that, in this diversity action, these claims are governed by Nebraska law. See Dethmers I, 23 F.Supp.2d at 1002-05.

In the first of its motions in hmine, Dethmers seeks to exclude six categories of evidence on relevancy and potential prejudice grounds pursuant to Federal Rules of Evidence 401, 402, and 403. In its second motion in limine, Dethmers formalized objections first raised in preparation of the final pretrial order to the admissibility of an October 4, 1994, letter from attorney Brian Laurenzo for Deth-mers to Jay Hesse, Automatic’s President. Dethmers’s objections to this evidence are also on the grounds of relevancy and potential prejudice. Automatic’s motion in limine seeks to exclude evidence from Dethmers’s expert on the measure and calculation of Dethmers’s damages, on the ground that those calculations are incorrect under applicable law, and therefore irrelevant.

II. LEGAL ANALYSIS

A. Relevancy And Prejudice

As noted just above, the parties principally challenge the admissibility of evidence on the grounds of relevancy and potential for prejudice. Rule 402 of the Federal Rules of Evidence provides generally that “[a]ll relevant evidence is admissible,” while “[ejvidence which is not relevant is not admissible.” Fed. R. Evid. 402. Rule 403, however, provides that even some relevant evidence may be excluded:
