The prior art must be considered when determining infringement. As defined by the <a href=\"https:\/\/vertexaisearch.cloud.google.com\/grounding-api-redirect\/AUZIYQFpOrUruFiYocntJOrdp0BaS053dssj3kn-m0KSqz01cFMjw5LNXZh5idG7jXr7NvdVfhLAhEt1ci937Bc8JHj5fmwK9p1VxCEK0X6Xy82ywOYuVmIk7_kMvsGyHyGIJ-L4hnZ-M-9obVepdHY=\" target=\"_blank\" rel=\"noopener noreferrer\">Federal Circuit<\/a> <sup id=\"ref-5\"><a href=\"#footnote-5\" class=\"footnote-ref\">5<\/a><\/sup>, the &quot;ordinary observer&quot; is someone who would be familiar with the prior art.

A design patent automatically expires 14 years after the issue date.

But with targeted changes to the housing, console, or boot shape, you can create a visually distinct product.<\/p>\n<p><strong>Yes, you can work with your OEM supplier to customize the machine&#39;s housing and avoid infringement.

The widely circulated &quot;20% modification rule&quot; is misleading. Courts do not care if a product looks marginally different. Adding extra buttons to a patented device does not erase infringement if the underlying mechanism remains the same.<\/p>\n<p>For design patents, however, visual changes matter more than internal ones. Design patents are entirely visual. And it is this visual comparison that opens the door for ornamental changes and additions to make an accused design look different enough to defend against a design patent infringement claim.<\/p>\n<h3>Effective vs. Ineffective Design Modifications<\/h3>\n<table>\n<thead>\n<tr>\n<th>Effective Modifications<\/th>\n<th>Ineffective Modifications<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Changing overall console shape (square to rounded)<\/td>\n<td>Adding a logo or label only<\/td>\n<\/tr>\n<tr>\n<td>Altering boot profile and seam patterns<\/td>\n<td>Internal component changes<\/td>\n<\/tr>\n<tr>\n<td>Redesigning control panel layout and button placement<\/td>\n<td>Color changes alone<\/td>\n<\/tr>\n<tr>\n<td>Modifying surface textures and materials<\/td>\n<td>Minor proportion adjustments<\/td>\n<\/tr>\n<tr>\n<td>Adding distinctive visual features (unique ventilation patterns)<\/td>\n<td>Changing brand name<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>How to Communicate Design Requirements to Your OEM Supplier<\/h3>\n<p>When our team initiates housing modifications, we follow a structured approach:<\/p>\n<ol>\n<li><strong>Provide reference images<\/strong> of the patented design to avoid<\/li>\n<li><strong>Specify which elements must change<\/strong> (e.g., console shape, boot stitching pattern)<\/li>\n<li><strong>Request 3D renderings<\/strong> before tooling<\/li>\n<li><strong>Conduct side-by-side comparisons<\/strong> with identified patents<\/li>\n<li><strong>Document all design decisions<\/strong> for potential legal defense<\/li>\n<\/ol>\n<p>When a company is in the early stages of product development, a freedom to operate search may reveal potentially problematic patents.

In many cases, they end up working with a 3-person trading company or a tiny manufacturing company. That might be a good fit for your project, of course.

Knowing how to respond protects your business from devastating losses.<\/p>\n<p><strong>To protect your business from legal risks, maintain thorough documentation of your design process, obtain a formal FTO opinion before importing, ensure your supplier contract includes IP indemnification, prepare defenses such as non-infringement or patent invalidity, and consult with a US patent attorney immediately if a claim arises.<\/strong><\/p>\n<p><img decoding=\"async\" style=\"max-width:100%; height:auto;\" src=\"https:\/\/kmslaser.com\/wp-content\/uploads\/2026\/02\/v2-article-1771343571557-5.jpg\" alt=\"Protecting business from legal risks and patent infringement claims for imported beauty machines (ID#5)\" title=\"Protecting Against Legal Risks\"><\/p>\n<h3>What Happens When You Receive an Infringement Claim<\/h3>\n<p>If a patent owner becomes aware of infringement against their patent, we advise the patent owner to take prompt action to stop the infringement. A patent is a grant by a government of the right to exclude others from making, sale, offer to sell, or unauthorized use of the invention described and claimed in the patent.<\/p>\n<p>As the accused party, you need to act quickly.

This will likely involve a noninfringement review by a patent attorney with experience in patent infringement litigation.<\/p>\n<p>For design patents specifically: Noninfringement of a design patent boils down to the appearance. There is only one claim in a design patent, and it essentially consists of the drawings.<\/p>\n<h3>Challenging Patent Validity<\/h3>\n<p>Prior art refers to any publicly available information\u2014such as patents, publications, or products\u2014that existed before the patent&#39;s filing. If prior art is found, the patent may be invalidated, and the lawsuit could be dismissed.<\/p>\n<p>Many defendants often file <a href=\"https:\/\/vertexaisearch.cloud.google.com\/grounding-api-redirect\/AUZIYQEyA2f994RkaX8lOQefS-Uls3r4ABme8HAj0mOx22o2od4mSXdQWbSeacWQA5Nhfmf_bQ4Tu0IfbwQt_1sTmBzAx6hfLoOo3siayGSgW6Ic8ZhLMai1Q4Of6VmhWXFw0GHpl2fdwFYsmx23MvIW\" target=\"_blank\" rel=\"noopener noreferrer\">Inter Partes Reviews (IPRs)<\/a> <sup id=\"ref-9\"><a href=\"#footnote-9\" class=\"footnote-ref\">9<\/a><\/sup> with the Patent Trial and Appeal Board (PTAB) to challenge a patent&#39;s validity. According to the USPTO, only about 50% of IPRs are instituted, and a significant percentage of claims that are reviewed end up being invalidated.<\/p>\n<h3>Documentation You Should Maintain<\/h3>\n<table>\n<thead>\n<tr>\n<th>Document Type<\/th>\n<th>Purpose<\/th>\n<th>Retention Period<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>FTO search results<\/td>\n<td>Shows reasonable care<\/td>\n<td>Indefinitely<\/td>\n<\/tr>\n<tr>\n<td>Design evolution records<\/td>\n<td>Proves independent creation<\/td>\n<td>20 years<\/td>\n<\/tr>\n<tr>\n<td>Supplier contracts with IP warranties<\/td>\n<td>Enables indemnification claims<\/td>\n<td>Contract term + 6 years<\/td>\n<\/tr>\n<tr>\n<td>Side-by-side comparison charts<\/td>\n<td>Supports non-infringement arguments<\/td>\n<td>Indefinitely<\/td>\n<\/tr>\n<tr>\n<td>Communication records with suppliers<\/td>\n<td>Documents design decisions<\/td>\n<td>10 years<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>ITC Investigations: A Special Risk for Importers<\/h3>\n<p>Another litigation avenue for the patent owner is to seek an exclusion order from the ITC pursuant to section 337 of the Tariff Act of 1930. Section 337 provides a patent owner with another forum to litigate infringement of their patent of products that &quot;are made, produced, processed, or mined under, or by means of, a process covered by the claims of a valid and enforceable United States patent.&quot;<\/p>\n<p>ITC cases move faster than federal court litigation and can result in exclusion orders blocking your products at the border. This is a significant risk for importers.<\/p>\n<h3>When to Consider Licensing<\/h3>\n<p>Sometimes the best business decision is to negotiate a license rather than fight. Consider licensing when:<\/p>\n<ul>\n<li>The patent appears valid and your product is clearly similar<\/li>\n<li>Litigation costs exceed potential licensing fees<\/li>\n<li>The patent holder is willing to negotiate reasonable terms<\/li>\n<li>You need to maintain market presence during the dispute<\/li>\n<\/ul>\n<div class=\"claim-pair\">\n<div class=\"claim claim-true\">\n<div class=\"claim-title\"><span class=\"claim-icon\">\u2714<\/span> Patent invalidity can be used as a defense against infringement claims <span class=\"claim-label\">True<\/span><\/div>\n<div class=\"claim-explanation\">If you can show the design patent should not have been granted because prior art existed, the patent may be invalidated and the infringement claim dismissed.<\/div>\n<\/div>\n<div class=\"claim claim-false\">\n<div class=\"claim-title\"><span class=\"claim-icon\">\u2718<\/span> Ignorance of a patent provides protection from infringement liability <span class=\"claim-label\">False<\/span><\/div>\n<div class=\"claim-explanation\">Intent is not required for design patent infringement. You can be liable even if you had no knowledge of the patent.
