Sight Sciences Inc. may have visions of a substantial settlement following Ivantis Inc.’s $60 million settlement with Glaukos Corp. this week or the Menlo Park, Calif.-based company may have its sights set on knocking a competitor out of the market entirely. Both are possible outcomes of the suit Sight Sciences announced this morning that alleges infringement of four of its patents by Ivantis for its Hydrus Microstent. Sight Sciences makes the Omni surgical system, which competes with the Hydrus and the Glaukos Istent in the minimally invasive glaucoma surgery (MIGS) space.

After three years of litigation and nearly a decade of skirmishes, Ivantis Inc. settled with Glaukos Corp. for $60 million to be paid in two installments, with the first $30 million due by Dec. 31, 2021, and the second $30 million by Dec. 31, 2022. In addition, Irvine, Calif.-based Ivantis will pay Glaukos a 10% royalty through April 26, 2025, on sales of Ivantis’ Hydrus Microstent in the U.S. or international sales supplied out of the U.S. With just two weeks to go until their scheduled court date of Sept. 28, the companies finally saw eye-to-eye, reaching a cross-licensing agreement and hammering out a covenant to refrain from future litigation regarding the technologies involved in the Hydrus or Glaukos’s Istent, both used to treat glaucoma.
