In a decision helpful to companies involved in the formulation of generally known ingredients (e.g., lubricants, glass, shampoos, cosmetics, etc.), the PTAB in Ex parte DeGeorge recently overturned an Examiner’s “kitchen sink” rejection based on the combination of two references, one of which listed six of Applicant’s required seven claimed components, all of them optional.

In DeGeorge the Examiner made a typical “kitchen sink” rejection by applying a reference from Applicant’s same general field that listed almost all of Applicant’s claimed components. Arguing that the claimed components were old, well-known, and used by Applicant for their intended purpose, the Examiner found the claim to be obvious by metaphorically throwing everything from the reference – except the kitchen sink (hence the name for such rejections) – into the composition.

In overturning the rejection, the Board found that because the Examiner “failed to identify a reason that would have prompted a person of ordinary skill in the art to combine the claimed components as the new invention does,” and because the Examiner had not “identified a reason to select and combine these independently listed components, absent Appellant’s disclosure” the Examiner failed to satisfy the requirement set out in KSR that an Examiner must provide some “articulated reasoning with some rational underpinning to support a legal conclusion of obviousness.”

Further, and in a statement particularly helpful to applicants fighting such “kitchen sink” rejections, the Board held that “[w]ithout a reason to combine the claimed components apart from their known uses, the Examiner’s reasoning relies on ‘hindsight reconstruction to pick and choose among isolated disclosures in the prior art.’” This requirement for more than just known utility to justify the selecting and combining of multiple known components in an obviousness rejection provides applicants with many options for rebuttal, as references typically used in “kitchen sink” rejections often simply list the claimed components with little or no description of their individual properties. Because Examiners very rarely provide supplemental references describing a particular component’s properties and behavior, “kitchen sink” rejections such as the one in DeGeorge may now be easier to rebut at the PTAB in view of this decision.

Examiners often use U.S. patents in making rejections, and they sometimes cite to the patent’s claims as evidence. In Ex parte Argembeaux the PTAB made it clear that claim scope, in and of itself, could not be used to broaden the overall teachings of a reference.

The claims in Argembeaux were directed to a skin cleansing preparation comprising less than 5% water. The Examiner cited only claim 13 of Franklin, a US patent, as the basis of the rejection – as both anticipating the pending claims and rendering them obvious. Because claim 13 of Franklin did not recite water (but listed all other components of Applicant’s claims) the Examiner found the listed components in Franklin’s claim to be anticipatory, and perhaps hedging his anticipation bet, also rejected the claims as obvious.

The Board reversed both rejections, dismissing the contention that “the absence of any mention of water in Franklin’s claims amounts to an affirmative disclosure that the compositions …. are necessarily water-free” in view of Franklin’s expressly described preference for an aqueous or aqueous-alcoholic carrier and the fact that all of the examples in Franklin used significantly more than 5% water. Based on the totality of Franklin’s disclosure, and finding no explicit disclosure affirmatively stating that water is merely an optional ingredient that may be omitted from the described compositions, the Board held that one of ordinary skill would not immediately envision (anticipation) nor be led to (obviousness) a composition as claimed containing less than 5% water.

The Argembeaux case can thus be useful in rebutting rejections where an Examiner improperly relies on a U.S. patent’s claims as evidence of prior art outside the scope of the specification’s underlying description.
