CAFC: Obviousness Analysis Must be Based on More than Common Sense

The Court recognized that “‘[c]ommon sense has long been recognized to inform the analysis of obviousness if explained with sufficient reasoning.’” However, “there are at least three caveats to note in applying ‘common sense’ in an obviousness analysis.” First, common sense is typically invoked to provide a known motivation to combine, and not to supply a missing claim limitation. Second, while some cases have allowed use of common sense to supply a missing claim limitation, “the limitation in question was unusually simple and the technology particularly straightforward.” Third, common sense “cannot be used as a wholesale substitute for reasoned analysis and evidentiary support, especially when dealing with a limitation missing from the prior art references specified.”

Common sense is no substitute for reasoned analysis and evidentiary support

O’Malley recognized that in Perfect Web the Federal Circuit did authorize the use of common sense to supply a missing claim limitation, but she pointed out that this was the only case where that has been done. O’Malley further explained that in Perfect Web that which was missing was “unusually simple and the technology particularly straightforward.” In fact, in Perfect Web, which dealt with sending e-mail to an e-mail list, the missing claim limitation was nothing more than merely repeating the step of resending e-mails in accordance with the claim. Thus, O’Malley explained that Perfect Web is properly considered an exception to allowing common sense to supply a missing claim limitation, rather than the rule.
