Narrative Opinion Summary
The case involves an appeal by Gencor Industries, Inc. against a judgment affirming the validity and infringement of U.S. Patent No. 4,787,938 held by Standard Havens Products, Inc. The patent concerns a method for asphalt production using a drum mixer to reduce degradation and pollution. The district court awarded Standard Havens $5,931,000 for patent infringement and $2,284,000 for breach of a confidentiality agreement. Gencor's defenses included claims of patent invalidity due to anticipation and obviousness, and challenges to the court's handling of a Certificate of Correction. The jury upheld the patent's validity and found Gencor liable for contributing to infringement, leading to the damages awarded. Gencor's motions for JNOV and a new trial were denied. The appellate court vacated the patent damage award for recalculation, focusing on lost profits from six infringing sales, and remanded for further proceedings. The court also addressed the applicability of the repair doctrine and implied license concerning future parts sales, ultimately affirming, vacating, and remanding various aspects of the case for reassessment, while denying a stay pending reexamination.
Legal Issues Addressed

Application: Gencor breached a nondisclosure agreement regarding confidential information related to the '938 patent, resulting in damages awarded to Standard Havens.

Judgment Notwithstanding the Verdict (JNOV)subscribe to see similar legal issues
Application: The district court denied Gencor's motions for JNOV or a new trial, affirming the jury's findings on patent validity and infringement.
Reasoning: The district court's conclusion that claims 1, 3, and 4 were not invalid due to anticipation was upheld.
Patent Claim Interpretationsubscribe to see similar legal issues
Application: The court interpreted the '938 patent claims to require isolation of the mixing zone from the hot gas stream, which was not taught by the Hepburn '649 reference.
Reasoning: The jury reasonably concluded that Hepburn '649 fails to 'isolate' the mixing chamber from the hot gas stream as required by the '938 claims.
Patent Damage Award and Lost Profitssubscribe to see similar legal issues
Application: The court vacated and remanded the patent damage award for recalculation, focusing on six infringing sales and excluding speculative future parts sales.

Patent Infringement and Validitysubscribe to see similar legal issues
Application: The court upheld the validity of the '938 patent and found that Gencor infringed it, awarding damages to Standard Havens.
Reasoning: The '938 patent, issued to Michael R. Hawkins and assigned to Standard Havens, pertains to a method for producing asphalt compositions using a drum mixer.
Reexamination and Certificate of Correctionsubscribe to see similar legal issues
Application: The withdrawal of the Certificate of Correction and the ongoing reexamination did not warrant a new trial, as the court found no new evidence to justify it.
Reasoning: The court ruled correctly in admitting the Certificate of Correction as a public document relevant to the case.
Repair Doctrine and Implied Licensesubscribe to see similar legal issues
Application: The court found that future parts sales by Gencor could not rely on the repair doctrine due to speculative nature and lack of payment assurance.
Reasoning: Determining whether future parts sales by Gencor constitute permissible repairs or impermissible reconstructions is complex and must be evaluated on a case-by-case basis.
