protect licensees against unwarranted litigation from Mohawk\/Unilin\u00a0<\/strong><\/em><\/li><li><em><strong>U.S. Patent \u2018460 is asserted by Mohawk\/Unilin in their recent ITC complaint<\/strong><\/em><\/li><li><em><strong>I4F preparing further actions to protect its licensees and freedom of choice<\/strong><\/em><\/li><\/ul>\n\n\n\n<p>WILLEMSTAD, CURA\u00c7AO \u2013 I4F, a group of companies providing patents and technologies to the flooring industry, announced that today it will file an inter partes review (IPR) petition at the Patent Trial and Appeal Board (PTAB) in the US Patent and Trademark Office (USPTO) to nullify Unilin\u2019s U.S. Patent No. 9,200,460. I4F will demonstrate that Unilin\u2019s \u2019460 patent is invalid in view of prior art showing that the claimed features were known in the flooring industry well before the date upon which the \u2019460 patent was filed.<\/p>\n\n\n\n<p>It is expected that the PTAB will render a decision on whether to institute the IPR within the next six months. A final written decision is expected to be issued by the PTAB no later than twelve months after the decision to institute the IPR.<\/p>\n\n\n\n<p>Mohawk\/Unilin are asserting the \u2018460 patent against dozens of Chinese manufacturers and exporters, as well as many US importers and distributors, in connection with an ITC complaint they recently submitted to the US International Trade Commission in Washington, D.C. Many of the accused manufacturers are Unilin\u2019s own licensees.<\/p>\n\n\n\n<p>I4F believes that the invalidation of the \u2018460 patent, in combination with the expected successful defense of the ITC action, will free the flooring industry from unjustified royalties and trade barriers. I4F is also preparing a series of actions to further protect its licensees.<\/p>\n\n\n\n<p>I4F says, \u201cUnilin\u2019s patents have been imposed on the flooring industry for far too long, and their invalidation will positively impact the industry\u2019s ability to choose the technology they, and their customers, prefer. We are confident that our licensees and customers are protected against these claims, and will continue to do everything in our power, to preserve freedom of choice for global flooring manufacturers. The removal of the fear management approach being adopted by Unilin is long overdue.\u201d<\/p>\n\n\n<div class=\"block file-list\">\n    <p><a href=\"https:\/\/i4f.com\/app\/uploads\/2021\/06\/190529-I4F-News-Release-IPR-case-ENGLISH-VERSION.pdf\" class=\"more\" target=\"blank\">ENGLISH VERSION<\/a><\/p>\n    <p><a href=\"https:\/\/i4f.com\/app\/uploads\/2021\/06\/190529-I4F-News-Release-IPR-case-DS-CHINESE-VERSION.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_60d3487e23c18\">\n          <div class=\"container\">\n            <h6 class=\"title text-center\">Tin m\u1edbi nh\u1ea5t<\/h6>\n            <div class=\"row pb-5\">\n              <div class=\"col-md-4\">\n                <p class=\"date\">Mar 31, 2026<\/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\/vi\/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\">\u0110\u1ecdc b\u00e0i vi\u1ebft<\/a><\/p>\n              <\/div>\n              <div class=\"col-md-4\">\n                <p class=\"date\">Mar 25, 2026<\/p>\n                <p>Parkett Magazin &#8211; i4F: John Rietveldt in an interview of the month<\/p>\n                <p><a href=\"https:\/\/i4f.com\/vi\/article\/parkett-magazin-i4f-john-rietveldt-in-an-interview-of-the-month\/\" class=\"more\">\u0110\u1ecdc b\u00e0i vi\u1ebft<\/a><\/p>\n              <\/div>\n              <div class=\"col-md-4\">\n                <p class=\"date\">Jan 27, 2026<\/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\/vi\/article\/lioncore-selects-i4f-as-exclusive-licensor-for-its-new-patented-l-spc-lightweight-rigid-core-product-build-up-and-composition\/\" class=\"more\">\u0110\u1ecdc b\u00e0i vi\u1ebft<\/a><\/p>\n              <\/div>\n            <\/div>\n            <p class=\"text-center\"><a href=\"https:\/\/i4f.com\/vi\/tin-tuc\/\" class=\"btn btn-outline-secondary\">Xem t\u1ea5t c\u1ea3 tin t\u1ee9c<\/a><\/p>\n          <\/div>\n        <\/section>\n\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":14,"template":"","categories":[],"class_list":["post-990","article","type-article","status-publish","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.8.1 -
