Since opening Loorak, Roy has litigated two major contract cases that resulted in significant, reported federal decisions.  In Merex A.G. v. Fairchild Weston Systems Inc. , 810 F. Supp. 1356 (S.D.N.Y. 1993), aff'd, 29 F.3d 821 (2d Cir. 1994), cert. denied, 115 S.Ct. 737 (1995), he succeeded in defeating a multi-million dollar claim for a commercial broker's fee.  The Second Circuit's opinion has become one of the leading decisions in New York on the doctrine of promissory estoppel.

In Lockheed Martin Corp. v. Walker, 149 F.3d 1377 (Fed. Cir. 1998), he succeeded in reversing a lower court's construction and interpretation of an options clause in a government contract.  On remand, this reversal -- one of only about 3% of the appeals in the Federal Circuit that are reversed annually -- eventually resulted in an award of more than $7 million to his client.  It also provided the basis for a follow-up claim that later resulted in an award of an additional $1.9 million.  Roy has since lectured on the topic to in-house counsel for a major aerospace company.
