John H. Owoc, aka Jack Owoc v. Monster Energy Company, a Delaware Corporation

Case status

DismissedDismissed

Where it stands

The case ended without a full Supreme Court ruling on the merits.

Question presented

1. Whether a civil jury may determine the scientific validity, biochemical identity, or physiological efficacy of a patented compound — and impose nationwide prohibitions on its labeling and promotion — in the absence of any regulatory action by the Food and Drug Administration, thereby substituting judicial verdicts for Federal scientific oversight in violation of due process and the separation of powers? 2. Whether a court violates due process by excluding critical, reliable defense evidence that goes to falsity, materiality, and affirmative defenses in a Lanham Act action — thereby preventing a defendant from presenting a complete defense? 3. Whether a court violates federal antitrust law and due process by permitting litigation to proceed where the suit is objectively baseless and brought as a competitive weapon to destroy a rival, thereby stripping it of Noerr-Pennington immunity under the sham-litigation doctrine? 4. May a lay jury impose the largest civil penalty in the history of the Lanham act based on admitted guesswork and standardless damages determinations, in Violation of a Court Order prohibiting speculation, without violating due process, where the verdict operates as punishment and de facto regulatory action rather than compensation for proven harm?
