Mandell Menkes obtained summary judgment on a breach of contract claim for a supplier of precision machined components. Mandell Menkes client Princeton Industrial Products Inc. supplied parts to a corporation with a machine gun mount contract for the U.S. Army. When the Army contract expired and was not renewed, the purchaser ceased paying for parts ordered via e-mail and delivered by Princeton. Princeton sued to collect the amount due for unpaid parts supplied pursuant to the e-mail and the Court granted summary judgment, finding that the e-mail from the purchaser modified the original purchase order, even though the email did not include an individually typed name of the sender. The court also found that defendant’s delayed attempt to return the ordered parts did not revoke acceptance of those parts. See Princeton Indus., Prods. v. Precision Metals Corp., 2015 U.S. Dist. LEXIS 107722, 87 U.C.C. Rep. Serv. 2d (Callaghan) 460 (N.D. Ill. 2015).
