Overview
Pi Symbol Trademark Controversy refers to the removal of several T-shirt designs bearing the mathematical constant “π” from Zazzle[3] after the online retailer was issued a cease-and-desist letter from a lawyer representing Paul Ingrisano, a New York City artist who obtained the trademark on the Greek letter, in May 2014.
Background
On November 21st, 2012, the founder of the Brooklyn-based apparel company Pi Apparels Paul Ingrisano[1] filed a trademark request for the symbol “π” followed by a period punctuation mark. The trademark was registered on January 28th, 2014.[2]
On May 16th, 2014, Zazzle received a cease-and-desist letter from a lawyer representing Ingrisano, who demanded the online retailer to remove an array of merchandises bearing the Pi symbol.
Online Reaction

The same day, artist Jez Kemp criticized Zazzle in a post on his personal blog[5] for removing his designs containing the symbol. On May 29th, artist Dave Lartique published a blog post[6] calling the Zazzle takedowns “asinine.”
