5. On information and belief, defendant EMC Corporation is a Massachusetts 

corporation with a principal place of business at One Dell Way, Round Rock, Texas 78682. EMC 

Corporation is wholly owned by its corporate parent, Dell Technologies Inc.

JURISDICTION AND VENUE

6. This is an action for patent infringement which arises under the Patent Laws of the 

United States, in particular, 35 U.S.C. §§ 271, 281, 284, and 285.

7. This Court has jurisdiction over the subject matter of this action under 28 U.S.C.

§§ 1331 and 1338(a).

8. This Court has specific and general personal jurisdiction over each defendant

pursuant to due process and/or the Texas Long Arm Statute, because each defendant has committed 

acts giving rise to this action within Texas and within this judicial district. The Court’s exercise of 

jurisdiction over each defendant would not offend traditional notions of fair play and substantial 

justice because each defendant has established minimum contacts with the forum. For example, 

on information and belief, each defendant has committed acts of infringement in this judicial 

district, by among other things, selling and offering for sale products that infringe the asserted 

patent, directly or through intermediaries, as alleged herein.

9. Venue in the Western District of Texas is proper pursuant to 28 U.S.C. §§1391

and/or 1400(b). Each defendant has established places of business in the Western District of Texas. 

Each defendant is registered to do business in Texas. Upon information and belief, each defendant 

has transacted business in this District and has committed acts of infringement in this District.

literally or under the doctrine of equivalents, by making, using, selling, offering for sale, importing, 

and/or distributing the Accused Products in the United States, including within this judicial district, 

without the authority of Brazos.

27. Defendants have received notice and actual or constructive knowledge of the ‘144 

Patent since at least the date of service of this Complaint.

28. Since at least the date of service of this Complaint, through its actions, Defendants

have actively induced product makers, distributors, retailers, and/or end users of the Accused

29. Since at least the date of service of this Complaint, through its actions, Defendants

have contributed to the infringement of the ‘144 Patent by having others sell, offer for sale, or use 

the Accused Products throughout the United States, including within this judicial district, with

knowledge that the Accused Products infringe the ‘144 Patent. The Accused Products are 

especially made or adapted for infringing the ‘144 Patent and have no substantial non-infringing
