Following a recent Federal Circuit decision, a patentee might now be able to assert a system claim against a single infringer for operating a distributed system, rather than naming joint infringers hosting portions of the distributed system. This is significant for entities that do business on-line, particularly enterprises with a cloud computing business model. Whereas in the past a patentee may have had to allege direct infringement among joint infringers (e.g., individual users, enterprises, and information technology system providers), and perhaps prove vicarious liability, now it may be possible to bring a direct infringement action against a sole infringer that might not be in possession of the complete system. E-commerce businesses, web-based providers of business services, providers of software as a service, electronic market makers, and other enterprises that use third-party server farms to host part, or all, of their system might now be named as the sole infringer. A patentee could perhaps now sue a competitor for infringement without having to sue the infringer’s IT provider. This could be particularly advantageous in cases where the patentee and the infringer share providers, and will permit the patentee to sue without jeopardizing its own business relationship with the provider.
