(Reuters) – E-commerce platform Shopify Inc owes patent holder Express Mobile Inc $40 million for infringing three patents related to mobile-website technology, a Delaware jury said in a verdict made public Thursday.

The federal jury on Wednesday awarded Express Mobile a lump sum and rejected Shopify’s argument that the patents are invalid. Express Mobile has sued dozens of tech companies for allegedly infringing the same and other patents, including in ongoing cases against Google, Meta and Amazon.
