Not sure if you are worried about syntax or performance. If you are worried about performance, just write your common Patterns in the same order among your multiple rules and the engine will reuse them. If you are worried about the syntax, i.e. not replicating the same code among multiple rules, the intermediate fact is probably the best solution right now. We want to implement rule inheritance or rule templates, but we don't have it yet.
