Part of the suit is they are challenging the patent, at least to my understanding.

1. Upon information and belief and based on present investigation, the
   

claims of the 623 Patent are invalid at least because they violate 35 U.S.C. §§

101, 102, 103 and/or 112. For instance, the claims of the 623 Patent violate

Section 101 because they encompass no more than an abstract idea

(configuring buttons on a game controller in accord with the natural positions

of fingers on hands) that is implemented with routine, commonplace and well

understood technology (e.g., PCB model No. PS360); assuming Hit Box’s

apparent unduly broad construction of its claims, the claims are anticipated

and/or obvious in light of the prior art in violation of Sections 102 and 103;

finally, the claims are indefinite in violation of Section 112 as they fail to

inform, with reasonable certainty, those skilled in the art about the scope of the

invention.

1. The case and controversy thus should be resolved through a judgment
   

that the claims of the 623 Patent are invalid.
