The Intellectual Property Owners Association (IPO) will offer a one-hour webinar entitled "Patent Claim Indefiniteness: Enzo v. Applera" on Wednesday, February 9, 2011 beginning at 2:00 PM (ET).  The IPO webinar will address the question:  just how definite do the claims of a patent need to be?  The webinar will look at the Federal Circuit's decision in Enzo Biochem, Inc. v. Applera Corp. that reversed a district court's judgment that two Enzo patents were invalid for indefiniteness; in mid-December, the U.S. Supreme Court asked the Solicitor General to weigh in on Applera's appeal.  The webinar will consider not only the issues raised by the Enzo case, but also the ways a patent can presently be found indefinite under 35 U.S.C. § 112, including indefinite means-plus-function claims and apparatus-plus-method claims in such cases as Telcordia, Aristocrat, Finisair, and IPXL.  The speakers include John Dragseth of Fish & Richardson P.C.; Prof. Michael Meurer of Boston University School of Law; and Mark Pals of Kirkland & Ellis, LLP.  The registration fee for the webinar is $120 (government and academic rates are available upon request).  Those interested in registering for the webinar, can do so here.
