`IPR Petition – U.S. Patent 7,519,814
`
`Petitioner Amazon.com, Inc. (“Petitioner” or “Amazon”) requests inter partes
`
`review of claims 3, 5, 7, 11-12, 15-16, and 31-34 (the “challenged claims”) of U.S.
`
`Patent No. 7,519,814 (“the ’814 patent”), which VirtaMove, Corp. (“Patent Owner”
`
`or “PO”) purportedly owns.
`
`INTRODUCTION
`
`The challenged claims recite methods for running software applications in
`
`“containers.” A container is a set of files needed to execute an application on a
`
`computer. The files in a container are grouped together and isolated from other files
`
`and applications on the same computer. Containers prevent different applications
`
`on the same computer from interfering with each other.
`
`A host of prior-art container technologies—Solaris zones, Zap pods, Linux
`
`VServers, and more—provide the same functionality described in the challenged
`
`claims. All of these container technologies (and several others) were available and
`
`well known before the ’814 patent’s earliest claimed priority date in September
`
`2003. Yet the patent fails to acknowledge these earlier container technologies.
`
`The Examiner was aware of at least one of these technologies—VServer—
`
`and expressly recognized its relevance to the patent claims. But the only reference
`
`the Examiner cited concerning VServer published in 2007 and thus was not prior art.
`
`This 2007 publication omits aspects of VServer that are material to the patent claims.

`IPR Petition – U.S. Patent 7,519,814
`
`The Examiner never considered the 2002 VServer reference raised in this Pe-
`
`tition, which is prior art. Nor did the Examiner review the prior art references that
`
`this Petition relies on concerning Zap pods and Solaris zones. Each of these refer-
`
`ences discloses the elements that were missing from the Examiner’s prior art and
`
`each of them renders the challenged claims unpatentable.
`
`The ’814 patent claims exclusive rights to container technology that belongs
`
`in the public domain. Because the patent contributed nothing to the art, PO is not
`
`entitled to exclude the public from practicing the challenged claims. Thus, the Board
`
`should cancel the claims.
`
`
`
`BACKGROUND
`
` Containers Versus Virtual Machines
`
`Instead of addressing the many container systems in the prior art, the ’814
`
`patent frames its contribution as an advance over “Virtual Machine technology, pi-
`
`oneered by VmWare” and released commercially in 1999. (Ex. 1001, 1:51-56; Ex.
`
`1010.) Like containers, multiple virtual machines can be hosted on a single physical
`
`computer and each one can be customized to meet the unique needs of the applica-
`
`tions it contains. (Ex. 1001, 1:27-56.) But the patent identifies a “key difference”
`
`between the Virtual Machine (“VM”) approach and the patent’s container-based ap-
`
`proach. (Ex. 1001, 1:56-61.) While VMs require a copy of the operating system
`
`-2-

`IPR Petition – U.S. Patent 7,519,814
`
`“for each application,” the container approach required only one copy of the operat-
`
`ing system (OS) “regardless of the number of application containers deployed.” (Id.)
`
`Because containers do not require multiple copies of the OS, they avoid the “perfor-
`
`mance overhead” associated with VMs. (Id., 1:62-63.)
`
`The claims of the ’814 patent capture this distinction over VMs by specifying
`
`that containers do not contain their own “kernel” (which is the core of an OS). (E.g.,
`
`id., 17:41-50 (claim 1); see also id., 2:39-42 (containers share a kernel from the un-
`
`derlying OS).) However, the patent’s distinction does not apply to the prior-art sys-
`
`tems presented in this Petition—all of which used containers rather than VMs.
`
` Containers Versus Shared Application Environment
`
`The ’814 patent acknowledged that, outside of VMs, multiple applications
`
`could share an operating system in a prior-art environment called “SoftGrid.” (Id.,
`
`2:4-12.) The patent distinguished SoftGrid in that it did “not isolate applications
`
`into distinct environments.” (Id.) In contrast, containers isolate applications to pre-
`
`vent them from interfering with each other. (Id., 4:39-42.)
`
` Containers in the Prior Art
`
`The ’814 patent fails to distinguish the many prior-art container systems that
`
`provided the same capabilities the patent describes—including the isolation and ker-
`
`nel sharing that the patent relies on to distinguish other prior art.

`
`
`
`Linux VServer (Gélinas)
`
`In October 2001, Jacques Gélinas disclosed a system for Linux computers that
`
`would allow “several independant [sic] virtual servers running on the same box
`
`(sharing the same kernel as well).” (Ex. 1017 (emphasis added).) This system be-
`
`came known as Linux VServer. (Ex. 1002 ¶38.) By 2002, Gélinas’s website de-
`
`scribed that VServer “split a Linux server into virtual ones with as much isolation
`
`as possible between each one, looking like real servers, yet sharing some common
`
`tasks.” (Ex. 1007, 1 (emphasis added).)
`
`To provide isolation, VServer built on a well-known computer command
`
`called “chroot,” which had been part of conventional operating systems for decades.
`
`(Ex. 1002 ¶39.) The chroot command confined a particular application process to a
`
`limited view of the computer’s file system, locking it out of other areas of the com-
`
`puter. (Id.) VServer built on chroot to also prevent processes from communicating
`
`with each other and isolate them from network resources. (Ex. 1007, 2-3; Ex. 1002
`
`¶39.) Thus, VServer created secure containers that isolate and confine processes
`
`while allowing them to share the kernel of the underlying server. (Ex. 1002 ¶39.)
`
`Although the Examiner cited a 2007 article that mentioned VServer (Ex. 1008,
`
`15), the Examiner never considered the 2002 publication on which this Petition re-
`
`lies. (Ex. 1001, 1-2.) The 2007 article omits key features of VServer that satisfy

`
`elements of the asserted patent claims and that are disclosed in the 2002 publication
`
`presented here. (Infra §VI.C.)
`
`
`
`Solaris Zones (Tucker)
`
`While Gélinas was developing VServer, Sun Microsystems was working on
`
`containers for its popular Solaris operating system. Sun published a press release in
`
`May 2002 that announced “containers” as part of Solaris 9. (Ex. 1009, 2-3.) Sun’s
`
`containers allowed “customers to run multiple applications on a single server, with
`
`fault, security and resource containment built-in.” (Id., 3)
`
`As Sun continued to develop its container technology, it filed a provisional
`
`patent application describing a system called Solaris Zones in May 2003. (Ex.
`
`1005.) Sun’s provisional explained that a “zone is an application container[.]” (Id.,
`
`92.) That provisional eventually matured into an issued patent. (Ex. 1004.)
`
`Sun’s technology allowed an operating system to be partitioned into a “global
`
`zone” and one or more “non-global zones”—containers that would isolate groups of
`
`processes from
