11.5.10.2 : A Question re SEPA Patches for 11.5.10.2 E-Business

Hi,

 We want to apply patch 13434486 for Direct Debit functionality for SEPA.
The patch readme says to apply the following patches with it for full functionality.

1. TAX patch 8452606
2. Inventory patch 8529225
3. AR Patches 8627857, 8623783
4. JL patch 7585468

I've checked our system and we use AR and have Inventory as a shared module.
We don't use TAX or JL modules so would I be right to assume that we just put on the patches for the products we use (or have shared) ?
In our case,  that would mean the 2 AR patches and the Inventory patch,  and we shouldn't worry about the TAX and JL patches ?
