Narrative Opinion Summary
The case involves an appeal by Star Scientific, Inc. concerning the validity and infringement of its patents related to methods for curing tobacco to reduce tobacco-specific nitrosamines (TSNAs). Star challenged the district court's judgment, which upheld a jury verdict finding the patents invalid due to anticipation, obviousness, indefiniteness, and failure to disclose the best mode. The Federal Circuit reversed the lower court's ruling on inequitable conduct and indefiniteness, asserting that the term 'controlled environment' was sufficiently clear. It affirmed the jury's finding of non-infringement, citing substantial evidence supporting the verdict, and upheld the denial of Star's motions for judgment as a matter of law (JMOL) and a new trial. The court confirmed the original September 15, 1998 priority date for the patents, impacting the status of certain prior art references. It also ruled that the failure to disclose the best mode was not substantiated. The decision was partly affirmed and partly reversed, remanding the case for further proceedings on infringement. Each party was ordered to bear its own costs, with the majority opinion emphasizing that skilled artisans could adequately manage the patented methods, while a dissenting opinion raised concerns about the clarity of the patent claims.
Legal Issues Addressed
Best Mode Requirementsubscribe to see similar legal issues
Application: The court found no evidence of a best mode violation, as Williams had not identified a best mode by the priority date.
Reasoning: RJR acknowledged that Williams had not identified a best mode by the priority date. Thus, there is no evidence of a best mode violation, leading to the reversal of the district court’s decision that deemed the Williams patents invalid for failing to disclose the best mode.

Application: The appellate court found no reversible error in the district court’s evidentiary rulings, including the exclusion of evidence.
Reasoning: The Fourth Circuit reviews evidentiary decisions for abuse of discretion and found no reversible error in the district court’s rulings, including on the controversial Burton slide, which did not affect Star's substantive rights.
Inequitable Conductsubscribe to see similar legal issues
Application: The Federal Circuit reversed the lower court's findings of unenforceability due to inequitable conduct, determining that the nondisclosure did not render the patents unenforceable.
Reasoning: On appeal, the Federal Circuit reversed the lower court's findings of unenforceability and invalidity, determining that the term 'anaerobic condition' was not indefinite and that RJR failed to demonstrate that the withheld prior art, including the Burton letter, rendered the patents unenforceable.
Judgment as a Matter of Law (JMOL)subscribe to see similar legal issues
Application: The appellate court affirmed the denial of JMOL on non-infringement but reversed it on the validity of the patents.
Reasoning: The court affirms the district court’s denial of Star Scientific's motion for Judgment as a Matter of Law (JMOL) regarding non-infringement, citing Star's dependence on Dr. Lee’s testimony and the presence of substantial untainted evidence supporting the jury’s verdict.
Patent Validity: Indefinitenesssubscribe to see similar legal issues
Application: The court found that the term 'controlled environment' was not indefinite, as it was understandable to a person skilled in the art.
Reasoning: Indefiniteness requires demonstrating that 'controlled environment' is insolubly ambiguous, but the record does not support this claim.
Patent Validity: Obviousnesssubscribe to see similar legal issues
Application: The court held that the combination of prior art references did not render the Williams patents obvious.
Reasoning: The combination of these references does not provide a clear motivation or instruction for a person of ordinary skill in the field to conclude that the claims of the ’649 patent are obvious.
Priority Datesubscribe to see similar legal issues
Application: The Patent Office confirmed the September 15, 1998 priority date, impacting the appeal by invalidating certain prior art claims.
Reasoning: The Patent Office confirmed September 15, 1998, as the correct priority date, which impacts this appeal significantly.
