The United States Court for the District of Delaware ruled that four Mannington patents from V\u00e4linge are invalid in the US, with immediate effect. The Court made the ruling in a case brought by V\u00e4linge alleging infringement against Halstead and Home Depot.<\/p>\n\n\n\n<p>The Court specifically determined that the phrase \u201cnot susceptible to damage caused by moisture\u201d which appears in every independent claim of the involved Mannington patents is indefinite. Consequently, each claim of every asserted Mannington patents is now invalid in the United States, regardless of the claim construction (also called \u201cMarkman\u201d in the US) outcome on the other contested claim terms. The decision effectively prevents V\u00e4linge from enforcing these now invalidated Mannington patents in the US.<\/p>\n\n\n\n<p>Other than in the Mannington patents, the parties disputed only four other claim terms, where two disputes were decided in favor of Halstead and Home Depot.&nbsp; While V\u00e4linge will have the opportunity to appeal, I4F believes the Delaware Court\u2019s invalidity decision is correct and does not expect an appeals decision before the patents expire. In the meantime, the Mannington patents are invalid with immediate effect and are expected to remain invalid, even after appeal.<\/p>\n\n\n\n<p>Additionally, in Europe, I4F has filed a nullity action based on prior art in Germany against Mannington patent EP\u2019665, a European patent in the invalidated U.S. Mannington patent family.<\/p>\n\n\n<div class=\"block file-list\">\n    <p><a href=\"https:\/\/i4f.com\/app\/uploads\/2018\/05\/180510-I4F-News-Release-Mannington-patents-in-US.pdf\" class=\"more\" target=\"blank\">ENGLISH VERSION<\/a><\/p>\n    <p><a href=\"https:\/\/i4f.com\/app\/uploads\/2018\/05\/180510-I4F-News-Release-Mannington-patents-in-US-Chinese.pdf\" class=\"more\" target=\"blank\">CHINESE VERSION<\/a><\/p>\n<\/div>\n\n\n    <\/div>\n  <\/div>\n          <\/div>\n        <\/section>\n\n\n\n        <section class=\"block news feed latest\" id=\"block_60d46423c341e\">\n          <div class=\"container\">\n            <h6 class=\"title text-center\">\u6700\u65b0\u52a8\u6001<\/h6>\n            <div class=\"row pb-5\">\n              <div class=\"col-md-4\">\n                <p class=\"date\">2026\u5e74 3\u6708 31\u65e5<\/p>\n                <p>i4F and Unilin Technologies\u00a0enter into non\u2011assert agreement on water\u2011repellent coating patents for laminate and wood flooring<\/p>\n                <p><a href=\"https:\/\/i4f.com\/zh-hans\/article\/i4f-and-unilin-technologies-enter-into-non%e2%80%91assert-agreement-on-water%e2%80%91repellent-coating-patents-for-laminate-and-wood-flooring\/\" class=\"more\">\u9605\u8bfb\u6587\u7ae0<\/a><\/p>\n              <\/div>\n              <div class=\"col-md-4\">\n                <p class=\"date\">2026\u5e74 3\u6708 25\u65e5<\/p>\n                <p>Parkett Magazin &#8211; i4F: John Rietveldt in an interview of the month<\/p>\n                <p><a href=\"https:\/\/i4f.com\/zh-hans\/article\/parkett-magazin-i4f-john-rietveldt-in-an-interview-of-the-month\/\" class=\"more\">\u9605\u8bfb\u6587\u7ae0<\/a><\/p>\n              <\/div>\n              <div class=\"col-md-4\">\n                <p class=\"date\">2026\u5e74 1\u6708 27\u65e5<\/p>\n                <p>Lioncore selects i4F as exclusive licensor for its new patented L-SPC lightweight rigid core product build-up and composition<\/p>\n                <p><a href=\"https:\/\/i4f.com\/zh-hans\/article\/lioncore-selects-i4f-as-exclusive-licensor-for-its-new-patented-l-spc-lightweight-rigid-core-product-build-up-and-composition\/\" class=\"more\">\u9605\u8bfb\u6587\u7ae0<\/a><\/p>\n              <\/div>\n            <\/div>\n          <\/div>\n        <\/section>\n\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":14,"template":"","categories":[],"class_list":["post-1448","article","type-article","status-publish","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.8.1 -
