As you probably know, SLAPP stands for "strategic lawsuit against public participation." Many states have anti-SLAPP statutes, which allow defendants to dismiss a lawsuit on the grounds that it was filed to intimidate the defendant into ceasing certain protected conduct the plaintiff finds distasteful, like publishing a nasty review of their product.
Fearing abuse of SLAPP suits, many states also allow a plaintiff to "SLAPP back" (boy are these legislators clever), wherein a plaintiff rebuts the defendant's SLAPP claim by showing that the lawsuit is, indeed, meritorious.

Charlotte Rutherford, former general counsel of Texas oil field services company Schlumberger Ltd., was sued by her former employer, alleging that she took trade secrets with her to her new company. Rutherford invoked Texas' SLAPP statute, arguing that Schlumberger's suit is frivolous and little more than retaliation for her new company, Acacia Research Group, suing Schlumberger over alleged patent infringement.
