Generally to protect a specific invented feature of an item.  For example many years ago (now expired) there was a patent on putting salt in soft plastic baits.  The patent was for putting salt in soft plastic baits.  One company tried to avoid the patent by using a different method than the inventor of the idea of putting salt in a soft plastic bait.  Ultimately several companies wound up paying royalties to the original inventor of the idea for many years.
