Its flagship product, a signature wedding band series, was the result of painstaking design and craftsmanship.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, the brand faced the ultimate betrayal: <strong>IP theft by a former employee.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A designer who had worked at Brand C resigned and established a rival company, Company V. Shortly after, Company V released a wedding band that looked suspiciously familiar. It was a near-replica of Brand C\u2019s signature design, with only trivial modifications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Brand C immediately filed a <strong>criminal complaint<\/strong> for design infringement. However, Company V did not back down. Instead, they launched a counter-offensive, filing a <strong>&#8220;Design Invalidation Trial&#8221;<\/strong> against Brand C. Their argument? &#8220;Brand C\u2019s design lacks originality and is similar to designs already known to the public.&#8221;<\/p>\n\n\n\n<figure class=\"wp-block-gallery columns-2 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\"><ul class=\"blocks-gallery-grid\"><li class=\"blocks-gallery-item\"><figure><img fetchpriority=\"high\" decoding=\"async\" width=\"775\" height=\"688\" src=\"https:\/\/sarangip.com\/en\/wp-content\/uploads\/2025\/12\/SE-2452d245-f154-450e-8be6-362cbceeef5d.png\" alt=\"Luxury wedding band design at the heart of a Korean design invalidation dispute between rival jewelry brands\" data-id=\"3505\" data-link=\"https:\/\/sarangip.com\/en\/?attachment_id=3505\" class=\"wp-image-3505\" srcset=\"https:\/\/sarangip.com\/en\/wp-content\/uploads\/2025\/12\/SE-2452d245-f154-450e-8be6-362cbceeef5d.png 775w, https:\/\/sarangip.com\/en\/wp-content\/uploads\/2025\/12\/SE-2452d245-f154-450e-8be6-362cbceeef5d-300x266.png 300w, https:\/\/sarangip.com\/en\/wp-content\/uploads\/2025\/12\/SE-2452d245-f154-450e-8be6-362cbceeef5d-768x682.png 768w\" sizes=\"(max-width: 775px) 100vw, 775px\" \/><figcaption class=\"wp-element-caption\">Luxury wedding band design at the heart of a Korean design invalidation dispute between rival jewelry brands<\/figcaption><\/figure><\/li><li class=\"blocks-gallery-item\"><figure><img decoding=\"async\" width=\"723\" height=\"1024\" src=\"https:\/\/sarangip.com\/en\/wp-content\/uploads\/2025\/12\/SE-d5cf7d11-8b66-4996-8fb6-83296b82aa6a-723x1024.png\" alt=\"Former designer's copycat brand filing a design invalidation trial against the original wedding band\" data-id=\"3506\" data-full-url=\"https:\/\/sarangip.com\/en\/wp-content\/uploads\/2025\/12\/SE-d5cf7d11-8b66-4996-8fb6-83296b82aa6a.png\" data-link=\"https:\/\/sarangip.com\/en\/?attachment_id=3506\" class=\"wp-image-3506\" srcset=\"https:\/\/sarangip.com\/en\/wp-content\/uploads\/2025\/12\/SE-d5cf7d11-8b66-4996-8fb6-83296b82aa6a-723x1024.png 723w, https:\/\/sarangip.com\/en\/wp-content\/uploads\/2025\/12\/SE-d5cf7d11-8b66-4996-8fb6-83296b82aa6a-212x300.png 212w, https:\/\/sarangip.com\/en\/wp-content\/uploads\/2025\/12\/SE-d5cf7d11-8b66-4996-8fb6-83296b82aa6a-768x1088.png 768w, https:\/\/sarangip.com\/en\/wp-content\/uploads\/2025\/12\/SE-d5cf7d11-8b66-4996-8fb6-83296b82aa6a.png 771w\" sizes=\"(max-width: 723px) 100vw, 723px\" \/><figcaption class=\"wp-element-caption\">Former designer&#8217;s copycat brand filing a design invalidation trial against the original wedding band<\/figcaption><\/figure><\/li><\/ul><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">It was a strategy to destroy the foundation of Brand C&#8217;s rights.
