Alcon Fails to Undo $34 Million Patent Loss, Must Pay Royalties

Federal Judge Jennifer L. Hall upheld a $34 million patent infringement verdict against Alcon Inc. over its Hydrus Microstent glaucoma device. The Delaware court denied Alcon's post-trial motions for judgment or new trial, preserving the jury's April 2024 findings that favored patent owner Sight Sciences Inc. Rather than blocking future sales, the judge imposed a 10% ongoing royalty on Alcon's Hydrus Microstent revenue.
