Canon initially sued Avigilon for infringement of five Canon patents in New York; it voluntarily dismissed that complaint after Avigilon gave notice that it intended to move to transfer to Massachusetts. Canon immediately refiled in the Northern District of Texas on October 5, 2017, alleging infringement of five Canon patents. Later that day, Avigilon brought this declaratory judgment action in Massachusetts on the same five patents, which Canon promptly moved to transfer to N.D. Texas. Avigilon, contending that venue is not proper in Texas and that other factors should create an exception to the “first-to-file” rule, moved for an expedited determination on Canon’s motion to transfer, seeking to have resolution before the date by which it must answer the Texas complaint (presumably with a motion to dismiss or transfer on the same grounds). Judge Talwani denied this motion, noting that the Northern District of Texas, as the court in which claims relating to the five patents was first raised, should be the court to determine whether venue is proper and whether any exceptions to the first-to-file rule apply. Judge Talwani stayed the Massachusetts case pending determination by the Texas court on any venue or transfer related pleadings or motions in the Texas case.
