Shoals secures initial ITC win in patent dispute with Voltage

<p class="p1"><span class="s1">Shoals Technologies Group has secured a favorable initial determination from a US International Trade Commission (ITC) judge, who found that Voltage violated US trade law by importing trunk bus products that infringe Shoals’ patents.</span></p><p><strong>From <a href="https://pv-magazine-usa.com/2026/02/09/shoals-secures-initial-itc-win-in-patent-dispute-with-voltage/" rel="noopener" target="_blank">pv maagzine USA</a></strong></p>
<p>Shoals Technologies Group says it has received a favorable initial determination from an administrative law judge at the ITC, advancing its patent infringement case against Voltage, LLC.</p>
<p>On Feb. 6, the judge found that Voltage violated Section 337 of the Tariff Act of 1930 by importing LYNX trunk bus products into the United States. The ruling states that these products infringe on Shoals’ intellectual property related to its Big Lead Assembly (BLA) solutions, a suite of products designed to connect solar panels to inverters that is covered under two U.S. patents.</p>
<p>The decision is a preliminary step in the ITC’s investigation process, and the commission is expected to issue a final determination by June 2026.</p>
<p>If the full commission upholds the judge’s finding, it could issue an exclusion order preventing the importation of the infringing Voltage products.</p>
<p>Shoals, which manufactures its BLA solutions in the United States, argues that the ruling reinforces the importance of domestic intellectual property protection.</p>
<p>“This initial ruling is a big step towards a win for American innovation and the domestic energy supply chain,” said Brandon Moss, CEO of Shoals Technologies Group.</p>
<p>But the company knows well that initial findings do not always result in agreement in the Commission’s final determinations. Shoals notes that its appeal regarding an earlier ITC decision — in which the Commission reversed an initial finding that Voltage infringed on a patent for an earlier version of the BLA — remains ongoing at the US Court of Appeals.</p>
<p>During the process of that initial infringement complaint, Shoals received new patents on its assembly that it said it believed would provide “protection against alternative designs that Voltage may create to bypass” the original patent.</p>
<p><b>Sector-wide litigation</b></p>
<p>The Shoals case mirrors a surge in intellectual property disputes across the solar industry as manufacturers seek to protect their technology amid a crowded market.</p>
<p>In January 2026, Canadian Solar <a href="https://pv-magazine-usa.com/2026/01/15/canadian-solar-wins-u-s-patent-litigation-against-maxeon/">announced a victory</a> at the US Patent and Trademark Office, which invalidated claims made by Maxeon Solar Technologies regarding tunnel oxide passivated contact (TOPCon) solar cell technology. Maxeon had previously filed a patent infringement lawsuit against Canadian Solar in the U.S. District Court for the Eastern District of Texas.</p>
<p>Similarly, First Solar recently <a href="https://pv-magazine-usa.com/2026/01/20/first-solar-wins-key-round-in-topcon-patent-dispute/">successfully defended</a> its TOPCon patents against challenges from competitors including JinkoSolar and Canadian Solar. In that instance, the patent office rejected petitions to review the validity of First Solar’s technology, allowing the US-based manufacturer to proceed with infringement litigation in federal court.</p>
