New cable - licensing needed?

If I manufacture a cable with the Sansa 30 pin connector for resale, do I need to license it from SanDisk?  Does Apple own any rights to this design, too?  Thanks.

sandisk uses a propriatary 30 pin connector. and yes if you manufacture the cable for sale you will need to license it from sandisk. 

allpe alos uses a 30 pin connector but it is different than sandisks and it is also propriatary.
