Now global footwear brand Skechers has entered the market and faces infringement suits from Fast IP, which manages Kizik&#8217;s patents.<\/em><\/p>\n\n\n\n<p><em>Skechers is heavily promoting its range of slip-on shoes, called \u2018Slip-ins\u2019. Competitor Kizik, which markets its products as \u2018the world\u2019s best hands-free, slip on shoes\u2019 and manages its patents via affiliate company Fast IP, has now sued Skechers for patent infringement at the UPC\u2019s local division Munich.<\/em><\/p>\n\n\n\n<p><em>Neither a preliminary injunction nor a revocation action has yet been filed. However, Fast IP filed a parallel infringement action at the Eastern District Court of Texas several months ago.<\/em><\/p>\n\n\n\n<p><em>Kizik\u2019s EP 4 003 084 protects a shoe design featuring a stabiliser that enables the wearer to put on the shoe quickly. The inventor named on the patent is Kizik\u2019s founder Michael Pratt. The EPO granted the patent this year.<\/em><\/p>\n\n\n\n<p><em>Inventor-led company takes on corporation<\/em><\/p>\n\n\n\n<p><em>Michael Pratt filed his first patent for hands-free slip-on shoes in 2009. He founded Kizik in 2017 and has licensed his inventions to Nike since 2019. His company continuously launches new types of shoes using hands-free slip-on technology and has a strong presence in the US, where Kizik operates numerous branches.<\/em><\/p>\n\n\n\n<p><em>Skechers has recently launched an aggressive marketing campaign for its own \u2018Slip-ins\u2019 series. Like Kizik\u2019s range, this series includes various models from sports to winter shoes.<\/em><\/p>\n\n\n\n<p><em>Also US-based, Skechers claims to be the world\u2019s third-largest footwear company. The company operates 5,300 shops globally and reported record annual sales of $8.97 billion in 2024. Headquartered in California, Skechers designs, develops and markets various lifestyle and performance footwear, apparel and accessories. 3G Capital acquired the company in September.<\/em><\/p>\n\n\n\n<p><em>Six patents asserted in US<\/em><\/p>\n\n\n\n<p><em>The defendants in the UPC proceedings are Skechers\u2019 subsidiaries in Germany, Belgium, Italy, Switzerland, and the US.<\/em><\/p>\n\n\n\n<p><em>According to the court register, Skechers has retained a team led by Powell Gilbert partner Tim Whitfield. The team works alongside Axel Verhauwen, Michael Bergermann, and Julia Vogtmeier from D\u00fcsseldorf IP firm Krieger Mes.<\/em><\/p>\n\n\n\n<p><em>Plaintiff Fast IP and Kizik work with a mixed team from Gr\u00fcnecker in the UPC proceedings, comprising Bernd Allekotte (lead), Julia Traumann and patent attorneys Jens Koch and Sebastian Flach.<\/em><\/p>\n\n\n\n<p><em>US firm Boies Schiller Flexner, which represents the companies in the parallel US proceedings through Washington partner Ryan Dykal, brought in the European team. The US complaint is available online and asserts six patents (patent numbers: 11,633,006, 12,274,325, 11,871,811, 12,121,096, D1038607 and D1037641) against various Skechers models.<\/em><\/p>\n\n\n\n<p>Information take from Juve Patent : <\/p>\n\n\n\n<p><a href=\"https:\/\/www.juve-patent.com\/cases\/skechers-sued-at-upc-and-in-us-over-hands-free-slip-on-shoes\">https:\/\/www.juve-patent.com\/cases\/skechers-sued-at-upc-and-in-us-over-hands-free-slip-on-shoes<\/a><\/p>\n\n\n\n<p>#patents #propertyintelectually <\/p>","protected":false},"excerpt":{"rendered":"<p>Slip-on trainers are known in Europe primarily through Nike, which licenses the technology from patent holder Kizik.
