With a patent portfolio reportedly comprising over 3,000 patent assets providing “protection in North America, Europe and Asia”, Sun Patent Trust (SPT) has filed its first US patent case to date, suing HTC (2:20-cv-00286) over four wireless communications patents received from Panasonic. Formed in 2015, SPT is among a steadily growing list of patent holders choosing to launch their first patent suits amid the recession brought on by COVID-19.
