The shortest PTAB opinion yet? July 30, 2014

Ex parte Daimer may set a record for the shortest PTAB opinion to date.  The actual opinion is a single paragraph and occupies about half a page of a document that is only 3 pages long.

Mr. Daimer claimed a carbothermic reduction furnace that has a “lining structure having a low Fe content of less than 0.1 % by weight.”  The Examiner cited a reference that was completely silent as to the presence or absence of Fe in a lining structure, so he interpreted that silence as meaning that Fe was present at a 0% level – “less than 0.1% by weight.”

In response, the APJ cited a single line from a precedential Federal Circuit case, which is also a logical truism: “Of course, the absence of evidence is not the same as evidence of absence.” Porter v. Secretary of Health and Human Services, 663 F. 3d 1242, 1264 (Fed. Cir. 2011) (O’Malley, J., concurring-in-part, dissenting-in-part)(internal quotations and citations omitted).  Therefore, the rejection was not supported by a preponderance of evidence, and was reversed.

This is a very useful opinion (as it its cite to Porter), because it provides another tool to use in those situations where an Examiner stretches a prior art reference too far to obtain a rejection.  Where a cited reference is silent as to a claimed term, that silence cannot be used against the applicant.

 

What “substantially” means July 29, 2014

Sometimes in the course of prosecution, either the applicant or the Examiner will proffer an argument about a claim term that is manifestly absurd. This was certainly the case in Ex parte Brosske. I am not even going to try to make the German “SS” letter or the umlaut on WordPress, so my apologies to him if he ever reads this.

One of the claims in Ex parte Brosske required that a blank be “substantially flat.”  The Examiner cited prior art that showed a blank having a 90 degree angle in it, and argued: “MPEP 2173.05 (b) states that the term ‘substantially’ is a broad term; therefore, the phrase ‘substantially flat’ is considered to include a blank that is not completely in a horizontal or vertical orientation. That is, a curve or bend in the blank still meets the claimed limitation.”

Fortunately, the PTAB applied common sense, and held that “a blank bent at a 90 degree angle does not constitute a “substantially” flat blank.”  I am a little surprised that the PTAB did not make note of the fact that the Examiner’s interpretation read the term “substantially” completely out of the claim.  I would be hard pressed to think of anything that wouldn’t be “substantially flat” if something bent at a 90 degree angle is considered “substantially flat.”
