A. Facts

In 1972 David Hatfield developed several agricultural products, including a fiberglass heating pad for newborn hogs. Osgood Products, Inc. (OPI) was later created to manufacture Hatfield’s products, and Hatfield became an employee.

In April 1974, Hatfield learned that OPI planned to develop a trademark, and he insisted that OPI use the name "Hatfield" in the mark. OPI agreed, and in 1975 the parties entered into a license providing in part that OPI could use the name Hatfield for 15 years as a "distinctive mark on all or part of the products" manufactured by OPI, whether or not they were invented by Hatfield. The agreement did not give Hatfield an express contractual right to inspect or supervise OPI’s operations in any way.

Hatfield later resigned from OPI, and had no further involvement or relationship with the company. Meanwhile, in March 1977, OPI applied to register the marks "Hatfield" and a circle design incorporating the name Hatfield. The marks were registered in January 1978.

In 1991, Hatfield sued OPI in the district court, based on his understanding that the parties’ 1975 license agreement had expired and that OPI’s use of the Hatfield marks constituted trademark infringement. Hatfield argued that the parties’ 1975 agreement was a limited license permitting OPI to use the "Hatfield" marks for only 15 years. OPI countered, and the district court agreed, that the agreement was a "naked" license, and therefore, Hatfield had abandoned any rights in the trademarks.

A. Facts

As an employee, Mr. Jones had assigned his patent to Total Service Inc. under his employment contract. According to the terms of this contract, Mr. Jones received compensation, expenses and bonuses for his assignment of the patent. Mr. Jones is now the CEO of the competitor and infringer, Acme Products, Inc. and alleges in the pending infringement suit that Total failed to make certain payments under his severance contract. But Total points out that the payments were withheld only after it became apparent that Mr. Jones had violated the restrictive covenant in both his employment and severance contracts which precluded his competing with Total directly or indirectly until a date certain.

B. Questions

What should the court’s decision be and why? [15 Points]


A. Facts

When ABC Corp. brought suit against XYZ Co. for infringement of its patent, the jury found infringement and awarded ABC over $1.2 million in damages. However, XYZ argued in defense that ABC had misused its patents. The jury agreed with this and the District court set aside the patent infringement damages it had earlier awarded.

There were four basic allegations of patent misuse: (1) ABC sent infringement notices including requests to cease and desist infringing activities to government contractors without informing those contractors of the available affirmative defense provided to them by 28 USC 1498 (see Appendix): (2) ABC threatened to void its warranties on its patented products that were used with non-ABC components; (3) ABC proposed to a third party, Ascor, a license agreement (which was never entered into) conditioned on Ascor’s purchase of unpatented products; and (4) ABC explicitly threatened to enforce its patent against Ascor and another company, even though those companies were government contractors also protected by Section 1498.

B. Question
