Narrative Opinion Summary
In a patent infringement case, Braintree Laboratories, Inc. sued Nephro-Tech, Inc. and G.P. Georges III, alleging that their calcium acetate product infringed on Braintree's patent for a phosphate-binding method used in treating end-stage renal disease. A jury trial resulted in a verdict affirming the patent's validity and finding infringement, awarding $300,000 in damages to Braintree. Post-trial, Braintree sought to amend the judgment, while the defendants pursued judgment as a matter of law or a new trial, which the court denied due to procedural shortcomings, including the failure to renew directed verdict motions. The court also rejected claims of inequitable conduct during the patent's reexamination, finding no clear and convincing evidence of misconduct. A permanent injunction was issued against the defendants, preventing further infringement and requiring changes to the product's marketing to avoid confusion with Braintree's patented use. The court awarded prejudgment interest on the damages, dismissing the defendants' objections. Ultimately, Nephro-Tech and Georges were prohibited from selling or promoting their product as a phosphate binder, with Georges personally liable due to his direct involvement in the infringing activities.
