PTAB holds unpatentable in IPR all claims in Clouding's data synchronization patent

Rackspace Hosting, Inc. asked Finnegan to challenge all claims in Clouding, Inc.’s data synchronization patent.  Less than one month later, Finnegan filed a petition for inter partes review on Rackspace’s behalf, supported by a newly identified expert and challenging the claims with newly identified prior art.  The inter partes review was instituted, and following an oral hearing, the Patent Trial and Appeal Board (PTAB) held all claims unpatentable.  In doing so, the PTAB found all claims anticipated by prior art, many by multiple references.
