After losing nearly $3 billion in research funding, Harvard University now risks losing control of its intellectual property in a latest Trump administration action.

The Trump administration is warning Harvard University that it could take over its patents, worth hundreds of millions of dollars, if a review finds the university hasn’t complied with federal law, an escalation of the continuing negotiations between the White House and America’s oldest university.

The Trump administration on Friday launched an investigation into Harvard’s patents derived from federally funded research, threatening intellectual property potentially worth hundreds of millions of dollars.
