Patten, 30, and his 37-year-old Finnish partner Heliovaara, who won the title two years ago, got revenge for their defeat by El Salvador's Marcelo Arevalo and Croatian Mate Pavic in the final at Queen's Club last month with a 7-6 (7-4) 7-6 (7-3) victory on Saturday.
The ATP may have unveiled proposals to reduce prize money and tournament sizes for doubles, but this match was played in front of a packed Centre Court before the women's final.
Patten, an outspoken critic of the planned cuts, said: "I'd be remiss not to mention at the start of these two weeks the ATP Tour submitted proposals to maybe cut some of the doubles.
"I'm a strong believer we need to grow the game. This is a fantastic example of the joy that doubles can bring.
"I hope the crowd enjoyed it. I believe we should be growing opportunities for kids instead of taking opportunities away."
Meanwhile, Britain's Alfie Hewett and Gordon Reid won their seventh wheelchair doubles title, beating Tokito Oda and Gustavo Fernandez 2-6 6-1 6-2 on Court One.
"It's a dream come true really, to play our home slam on a court like this and come away with the win," said Reid.
"We know exactly how strong these guys are, they are the Australian Open and US Open champions, and when you've got someone with the size of Tokito's forehand and someone with the size of Gusty's biceps, it's not easy."
Hewett added: "We've had so many finals here, 10 years ago we won our first and who would have thought 10 years on we'd still be here with seven titles."
