Patent Claims Over Cialis Revived by Federal Circuit

A federal appeals court has vacated a patent board's finding that a patent for treating penile fibrosis was invalid, reviving a dispute over the erectile dysfunction drug "Cialis."

Remanding the case to the Patent Trial and Appeal Board, the Federal Circuit Court of Appeals said the board must reconsider the obviousness of the method for "arresting or regressing" penile fibrosis. In Los Angeles Biomedical Research Institute v. Eli Lilly and Company, the research firm alleged the pharmaceutical company induced patent infringement through repeated treatments of Cialis.

The question revolves around the long-term use of the erectile dysfunction drug and its positive effects on penile fibrosis.
