Narrative Opinion Summary
In the case of Duhn Oil Tool, Inc. v. Cooper Cameron Corporation, Duhn Oil accused Cooper Cameron of infringing its patent related to wellhead systems. The jury found Cooper Cameron liable for infringing specific claims of the '925 Patent and awarded Duhn Oil damages. However, the jury also determined several claims were invalid due to obviousness and anticipation. The trial's scope was contested, with Duhn Oil asserting the jury's findings were advisory except for willful infringement. The court clarified that infringement and validity, as legal issues, required a jury trial under the Seventh Amendment, while equitable claims like inequitable conduct did not. The court dismissed Cooper Cameron's defense of inequitable conduct, finding no intent to deceive the Patent Office. Due to inconsistencies in the jury's findings on obviousness and anticipation, the court ordered a new trial on these issues. The case highlights the complexities of patent law, particularly in balancing legal and equitable claims, and underscores the importance of clear jury demands and the parties' rights under the Federal Rules of Civil Procedure.

Reasoning: The rights to a jury trial in patent cases are unaffected by the parties' positions... Both infringement and validity issues are legal matters necessitating a jury trial, while claims based on equity, such as inequitable conduct, do not afford this right.
