A Watertown company won the first round a court battle between two Boston-area tech firms that specialize in the burgeoning field of 3-D printing for industrial and commercial uses. A federal jury in Boston on Friday held that Markforged Inc., did not violate patents held by Desktop Metal Inc. of Burlington. Desktop Metal, which also makes 3-D metal printers, sued Markforged in March, claiming that Markforged had violated two Desktop Metal patents.
In a second case, Desktop Metal has alleged that one of its interns stole trade secrets and handed them over to Markforged, where the intern’s brother held an executive position. That case is expected to go to trial later this year.
