Good performances rather than points is Liam Buckley's key concern at this stage of the season.
The Saints climbed to fifth in the table after this win at Jackman Park and the manager believes that there is more to come from his team in the weeks ahead.
He said: "We're not looking at the league table. We're just looking at our performances and, if we can get them better, we'll do better. That's the bottom line.
"No matter where we're playing, whether it's away or at home, we've a way of playing and we want to make that better. At the minute we're still finding our way but we'll get there over the next few weeks."
Limerick manager Martin Russell was pleased with his team's effort, but bemoaned their poor finishing.
"There wasn't a lot in the game. They probably had a bit more possession but I think we were a threat. We just didn't take the chances we created. Had we done that, we would definitely have got a point.
"It was good to get the goal back at 2-0 down, which meant that we were right there to the end. I think Pat's are going home relieved that they've got the three points."
Aaron Greene struck twice for St Pat's, finishing off a goalmouth scramble on 30 minutes before executing an exquisite chip over Conor O'Donnell in the second half.
Ian Turner gave Limerick hope by scoring from a 75th-minute free-kick to ensure a nervy finish for the visitors.
