Brooklyn entrepreneur says he's receiving death threats for using the pi symbol to brand his clothing line

"“I was wondering if it was evil or stupid,” New York University Law Prof. Christopher Sprigman said. “I realized I didn’t have to decide — it’s both.”

No corporation could force pi to stand in for their brand like the swoosh does for Nike, because it’s already part of the everyday language, he said — people see the symbol and think of the math constant, not Ingrisano’s clothes.

“Trademark law is a dangerous thing,” Sprigman said. “It gets taken too far a lot, and this is one of those cases.”"
