Major, maybe.  Different, yes: 
 
 Algorithm       Intellectual Property Protection 
------------------------------------------------------- 
 RC4             Trade Secret 
 RC5             Patent (applied for?) 
 IDEA            Patent 
 DES             Open 
  
 
Does anyone have the patent numbers for RC5 and IDEA?
