GPNE sued Apple for direct infringement of claims in two of GPNE’s patents. The patents at issue relate to a two-way paging system, where the paging devices are capable of not only receiving messages but also sending messages back in response. The claims asserted by GPNE all recited “nodes” rather than “pagers,” even though the word “node” was not used anywhere other than in the Abstract of the two patents containing the asserted claims. Seizing on this, Apple argued at the Markman hearing that a “node” as claimed should be construed as being a “pager.” The district court ultimately agreed with Apple, and ultimately so too did the Federal Circuit.
