Patent assertions are seldom made lightly and are never received casually. Post grant challenges should be considered an almost inevitable response to an assertion of patent infringement. 

Slater Matsil is intimately familiar with the procedures and strategies necessary to successfully navigate the numerous procedural challenges to patents  under the America Invents Act (AIA). Slater Matsil was one of the first firms to file for an Inter Partes Review; for instance, when that procedure became available in 2013 under AIA. Slater Matsil has litigation and prosecution experience, both of which are vital to maximizing the chances for a successful outcome to a post grant challenge.
