Ratner v. M&M Control Serv., Inc., No. 08 C 6928, Slip Op. (N.D. Ill. Jan. 5, 2009) (Shadur, Sen. J.).
Judge Shadur ordered that certain denials in patent defendant’s answers be stricken pursuant to Fed. R. Civ. P. 8(b)(5) and 11 (b). The Court held that when a defendant lacked sufficient knowledge to answer an allegation and so stated, it was deemed a denial pursuant to Rule 8(b)(5). But defendant cannot actually deny the allegation because defendant has already stated that it lacks sufficient knowledge to admit or deny the allegation. As such, denying the allegation conflicts with Rule 11(b) obligations.
