Summary Judgment of Invalidity (Obviousness) Granted; Motion for Leave to Amend to Assert Walker Process Claims Denied

By Michael C. Smith

The Ohio Willow Wood Company v. Thermo-Ply, Inc., (9-07-cv-00274) (Nov. 20, 2009)
Judge: Ron Clark
Holding: Defendant's Motion for Summary Judgment GRANTED; Defendant's Motion to Amend PICs DENIED
On Friday Judge Clark granted summary judgment ending this case.  It has an interesting procedural history.  After plaintiff OWW filed suit against TP, another company intervened, claiming ownership rights in the patent.  Judge Clark held a hearing on the inventorship and invalidity issues raised to the defendant and stayed the case pending resolution of these issues.  The defendant then filed a motion seeking to assert Walker Process claims (Sherman Act violations which allege fraud before the PTO).  Judge Clark denied the motion, concluding that TP could have met the deadline in the scheduling order for asserting such a claim.
More interesting (not that anyone could ask for more from the first order, of course) is another order, also from Friday, in which Judge Clark granted TP's motion for summary judgment that all asserted claims were invalid as obvious (SJ on anticipation was sought, but not granted).
