Litigation summary

As of April 26, 2026, research indicates that the patent owner, E Vision Smart Optics Inc., has initiated a broad litigation campaign. While no cases have been found specifically asserting US patent 11,971,612, the patent owner filed multiple lawsuits against major eyewear and electronics companies in late 2023, asserting other patents from its portfolio. The '612 patent is part of the same family and technology group, making it highly likely to be asserted in these or future cases.

The existence of an Inter Partes Review (IPR2025-01512), filed by Luxottica of America against the '612 patent, is a direct consequence of this litigation campaign. IPRs are overwhelmingly filed as a defensive measure by companies that have been sued for patent infringement.

The most relevant known litigation that prompted the IPR is:

• Plaintiff(s): E-Vision Optics, LLC and e-Vision Smart Optics, Inc.
• Defendant(s): Luxottica Group S.p.A., Luxottica U.S. Holdings Corp., and Luxottica of America, Inc.
• Jurisdiction: U.S. District Court for the Central District of California
• Case Number: 8:2023cv02013
• Filing Date: October 26, 2023
• Outcome or Current Status: The case is currently active. The defendants responded to the lawsuit by filing IPRs against the asserted patents and related patents in the portfolio, including the IPR against US 11,971,612. The district court case is likely to be stayed pending the outcome of the PTAB proceedings.

Other parallel litigation filed by E Vision Smart Optics Inc. includes cases against Seiko Epson and Lenovo, indicating a wide-ranging assertion effort. Although the specific patents asserted in those cases are not detailed in the available documents, they are part of the same overall campaign.
