It is well known that hindsight reconstruction is an insidious error that infects patent prosecution. The Federal Circuit has noted that it is a difficult task to avoid “subconscious reliance on hindsight” and tools are available to “inoculate the obviousness analysis against hindsight”. However, it is well known that practitioners could benefit in countering the pernicious problem of subconscious hindsight directed analysis with additional tools. This article is intended to provide an additional tool outlining a new analytical approach to detecting hindsight: 1) identification of a proxy problem upon which an “obvious” advantage is predicated, and 2) showing that either a) the proxy problem is secondary to the problem solved by the inventor and would have been insufficient to drive advancement of the art, and that the examiner has failed to show that a person of ordinary skill in the art (POSITA) would have regarded the proxy problem as sufficiently significant so as to require solution, or b) a showing that the proxy problem posed to POSITA presupposes the problem and its solution as solved by the inventor and is derivative. Once it is shown that the proxy problem is subsidiary or presupposes the problem solved by the inventor it becomes a less difficult task to show that the invention was not considered as a whole or that the problem was improperly phrased.
