Did you push a fork down a few cm deep all over the areas you tried to re-seed? If not, the seed is probably sitting in an unsuitable place, or has been eaten by birds. Also, how soon did you do this after the patches appeared? As already said, you need to wait a month or so before re-seeding. You also need to ensure the seed is kept moist at all times - the occasional rain shower isn't enough.
