New York, NY--On April 26, 2024, Christopher Designs, Inc. (“CDI”) filed a patent infringement lawsuit in the United States District Court for the Southern District of New York alleging that Henri Daussi, LLC (“Daussi”), willfully infringes multiple claims of U.S. Patent No. 9,398,791 (“the ‘791 patent”).  Christopher Slowinski, the founder of CDI and internationally acclaimed jewelry designer, is the inventor of the `791 patent.  The ‘791 patent is entitled:  “Diamond Cuts Providing Increased Light Amplification.”  The complaint alleges that Daussi is now offering for sale a diamond that copies the patented design disclosed in the ‘791 patent and infringes multiple claims of the patent.  The complaint identifies the Daussi 1.5 carat diamond as the infringing product.  The complaint as filed can be reviewed by clicking on this link.

CDI has been at the forefront of innovation in jewelry design for years and holds multiple patents on its innovations.  These patents include: U.S. Patent No. 11,576,471, and U.S. Des. Pat. Nos. 813,715, 816,541, 833,324, 897,886, and 976,747.  CDI has made and continues to make substantial investments in its patent portfolio to protect its innovations in the field of jewelry design and intends to enforce its rights vigorously against any industry participants who infringe on its patents.  CDI believes in free and fair competition and respects the intellectual property rights of others and will not stand idly by while its hard-earned patent rights are infringed.
