The Nearmap share price fell by 23% after investors responded to the legal case relating to patent infringement. Nearmap said that it was made aware on the morning of 5 May 2021 of a complaint filed against its subsidiary, Nearmap US Inc, in the United States District Court (District of Utah, Northern Division). The complaint alleges patent infringement relating to the plaintiffs’ roof-estimation technology. The allegations do not affect Nearmap’s core proprietary technology and do not affect the surveying of imagery or the delivery of premium content. The business remains unaffected, according to management. This complaint has been filed on behalf of Eagle View Technologies Inc and Pictometry International Corp. The plaintiffs are seeking unspecified monetary damages and the prevention of alleged further infringement in relation to the plaintiffs’ roof-estimation technology.
