The Patent Trial and Appeal Board (PTAB) recently found all challenged claims of patent 8,373,012, covering methods for making renewable jet fuel from blendstock, unpatentable for obviousness. The final written decision issued for inter partes review (IPR), Butamax Advanced Biofuels v. Gevo, claims that “”the background knowledge possessed by a person having ordinary skill in the art is an integral part of an obviousness analysis.””

Butamax Advanced Biofuels was represented in this IPR by a team of Sterne Kessler PTO litigation and Clean technology specialists including Peter A. Jackman, Deborah Sterling, Ph.D., Pratibha Khanduri, Ph.D., Christopher M. Gallo, Ph.D. & Rami Bardenstein.
