Summary: Greedy, Lazy Patents = Invalid
Craige reviews a case study of obviousness by tracing how common errors in lazy drafting and greedy claiming lead inexorably to weak patents. In Owens Corning v. Fast felt, the federal Circuit shoots down a patent on gravure deposited nail tabs for roof shingles, even though the claims survived the inter partes review process.
