I'm not sure what you're seeking to accomplish, but the complaint was only filed on April 17, and, as you noted, a motion to dismiss was filed on May 29.
The MTD is supposed to be fully briefed by July 21, but it may be several months (maybe even a year or more) before the court rules on the motion.
If the case survives, then the plaintiffs will have to file a class certification motion, which could take more than a year. The two name plaintiffs purport to be suing "individually, and as representatives of a Class of Participants and Beneficiaries of the Schlumberger Technology Corporation Savings and Retirement Plan." Are you such a person? If so, and if a class is certified, then you might receive a notice.
