Have any of you ever applied for a patent? Quick question. Say you have something that is really easy to make but has never been manufactured and sold that way because up until now there was not a great need for it. But now there is. Can it be patented? There is nothing new being invented... its using an existing material to construct something that is already very common. I'm trying to think of an example that would illustrate my point. OK... this is obviously not it... but lets just say "the heels of a shoe". And say... (remember I'm just making this up here... ie Lawernce Lugar... stfu already and don't even chime in).... .....you are some orthopedic surgeon and you have figured out that constructing shoe heels out of a certain hardened foam that is used in industry for other purposes.... eliminates lower back pain in millions of subjects. Could that be patented? You don't own the shoes, and you don't own the patents on the material... say 3M does.... but your application of that material to be used as a shoe heel is new and original. Would that be eligible for a patent?
