I filed for a utility patent and afterward I found someone's utility patent that won't allow mine to be approved.
A close example is: applying for a specific design for a shoe and hoping that it would be an all encompassing utility patent for a shoe. Then one finds out someone already patented a more general patent that is anything surrounding the foot with no specific drawing - only a general drawing of a circle around the foot and referencing anything that goes around the foot is the all encompassing shoe patent.
Should I now file a specific design patent for my shoe - or will the more specific design that I filed for in my original utility patent cover the specific design, assuming the drawings I provided are specific and detailed?
