agreed to test the product in 22 stores, where the product sold well. Costco took the product into all of its stores nationwide. Soon after JumpSport expanded to other retailers.
In 1998 Publicover developed two more trampoline safety inventions. After Publicover suffered a minor leg break while testing another manufacturer's trampoline with his kids, he focused on improving the shock-absorption characteristics of the trampoline bed, patenting the StageBounce and DoubleBounce systems. Between 1998 and 2000 his company introduced four trampolines based on these safety features.
In 2000, Publicover raised capital from Silicon Valley's

in 2005.
Publicover says that more low-quality knock-offs quickly flooded the market. In 2001 Publicover sued Wal-Mart, Hedstrom, Jump King, and several other infringing companies.
Publicover ended up winning a seven-figure settlement from Hedstrom and JumpKing and while Wal-Mart was not found liable, they were banned from selling the copycat products. In 2007, JumpSport's 15-employee business had $13 million in sales and in 2008 Publicover claimed over $50 million of lost sales due to patent infringement.
Legacy
From 1998 to 2006, enclosures gained broad acceptance in the marketplace and were being sold together with more than 80% of all trampolines. In that same period, U.S. sales of trampolines doubled from around 550,000 to 1,200,000 while total annual reported trampoline injuries began to decline.
Personal life
As of 2014, Publicover lives in Saratoga, California, with his wife, Valerie DePiazza Publicover. They have one son and two daughters.
