The battle led to a sharp decline of 10%, or $50 million, in Newell Brands' sales of writing utensils during the most recent quarter, according to the Journal.
But Newell CEO Michael Polk said he doesn't regret putting pressure on Office Depot.
"These things, you have to be prepared to see them all the way through," Polk told the Journal.
The fight between the two companies has since been resolved. In remarks to the Journal, Polk blamed the dispute on the pressure that Office Depot is facing as sales of office supplies migrate online.
"When those guys feel that foot-traffic pressure, they have to cover their margins and their earnings," he said. "How to they do that? They hold on to spending and don’t pass it through to the consumer. If you don’t contest that when it occurs, you find yourself funding their margin and you can’t do that."
