The Federal Circuit in Nichia v. Everlight has just (arguably) made it even harder to obtain a permanent injunction in a patent case.
What is the patent right again? Oh yeah - this:-
"It is no longer debatable what the patent right is. As I just explained, the Supreme Court told the country in 1852 in Bloomer v. McQuewan that it consists altogether
in the right to exclude others – and that is all it is. It is not an
ambiguous “exclusive right”; it is a simple right to exclude others.
Period."
