Sight Sciences Inc. filed a lawsuit in the United States District Court in Delaware against Ivantis Inc. for infringement of U.S. Patent Numbers 8,287,482, 9,370,443, 9,486,361, and 10,314,742. These patents describe and claim devices and methods for reducing intraocular pressure in the eye.
 
Sight Sciences’ complaint seeks an injunction to prevent the infringing manufacture, use and sale of the Hydrus Microstent, along with money damages for past infringement. “We filed this lawsuit to protect and defend our commercial, market and intellectual property leadership positions within the field of canalicular glaucoma surgery,” said Paul Badawi, co-founder and CEO of Sight Sciences, and co-inventor of the patents-in-suit.
 
Since 2006, Sight Sciences has been innovating in circumferential glaucoma surgery (implantable and non-implantable). Its extensive patent portfolio covers many approaches to circumferential glaucoma surgery, including, but not limited to, canalicular scaffolding implants, canaloplasty and trabeculotomy devices and methods, and methods of drug delivery within the canal.
