Narrative Opinion Summary
In this case, the appellant challenged a summary judgment ruling from the United States District Court for the Southern District of Indiana, which found no infringement of his patent by a dietary supplement marketed by Rexall Sundown, Inc. The appeal was reviewed by the Federal Circuit, which upheld the lower court's decision, affirming the interpretation of the patent claims and the absence of material fact issues concerning infringement. The patent in question involves methods for treating or preventing macrocytic-megaloblastic anemia through specific dosages of folic acid and vitamin B12. The appellant argued that the claims were misinterpreted by introducing an intent element not supported by the patent's language or history. However, the court determined that the claims require administration to humans in need of treatment for the specified anemia, a requirement not met by Rexall's marketing of the supplement. The appellant's evidence of infringement was deemed insufficient, as it relied on speculation rather than concrete evidence of customer use for the patented method. Consequently, the court affirmed the district court's ruling of noninfringement, maintaining the grant of summary judgment in favor of Rexall.
