I am looking to manufacture and sell a "cocktail shaker set" I've found a few patents that might prevent that, but I have no idea how patents work nor do I know if so.ething this broad can be patented? There may be more, but here are some that I'm worried about... 1. USD483982 S1 2. US6913165B2 3. US20040066705A1
Any help would be very much appreciated!!! Thank you in advance.
