Yes...many lawsuits are ludicrous. Sometimes the silliest ones pay off, though.
Recently, we had a case where a lawyer bought the copyright to an old kids' song simply to sue a pop group for infringement...a short horn riff they used in hit song years before.
They claimed they had never heard the original song.
They lost and had to pay up big.
Betting the lawyer was an ambulance chaser, too.
I think the hit song was the Australian yachting team's theme during the 80s Americas Cup series.
For over 20 years, the original owner of the kids' song hadn't been concerned about an infringement.
My RayBans have a tiny "B&L" etched into the tops of the lenses.
Must get them fixed.
Currently using a nice pair of Zeiss.
Not knowing the answer is not dumb. Providing an answer, anyway, is dumb.
