It would be like suing Ford because their car resembles a Chevy involved in an accident.
This is a trickier issue than the linked article suggests. The Supreme Court has held that the manufacturers of generic drugs cannot be sued based on the warnings/instructions/etc. on their drugs, because, by law, generic drugs must have the same labeling as the name-brand drugs. So, while the person in the Alabama only took the generic drug, he was suing based on allegedly inaccurate/incomplete warnings, which are the responsibility of the brand name manufacturer.
The courts allowing people to sue the inventor because they had a bad trip on the generic? That's like giving standing to someone who crashed a Ford, so they can sue GM too because both products are car. Complete idiocy.
But you watch-- the Feds will come down hard on Alabama for this.
Ping to the state list.
Lawsuits like this are why the profession is regarded with less respect thanthat of a tur...er...Dorkbama producr lying on the sidewalk.
