Common sense can be applied in obviousness determinations, but it must be supported by reasoned analysis and evidentiary support. Key points about using common sense include: It can inform the obviousness analysis if explained with sufficient reasoning A specific teaching or suggestion in a particular reference is not required Conclusory generalizations should be avoided As…
Read MoreIs the ability to combine references sufficient to establish obviousness?
