MEMORANDUM *
M2 Software argues that the district court erred in determining the size of its business operations. However, we must accept the district court’s findings regarding the scale of M2 Software’s business *124unless we have a “definite and firm conviction that a mistake has been committed,”1 and we do not.
M2 Software also argues that the district court erred by failing to consider likelihood of confusion as to “source” and focused only on likelihood of confusion as to goods. However, the district court employed the analysis from AMF v. Sleek-craft Boats2 in evaluating M2 Software’s assertions regarding likelihood of confusion. In so doing, the district court did evaluate whether a likelihood of confusion as to source exists in the minds of consumers.3
M2 Software argues that the district court erred by failing to consider the doctrine of reverse confusion. However, M2 Software’s mere use of the term “vice versa” was insufficient to raise this issue properly to the district court. As neither M2 Software’s first amended complaint nor motion clearly raised this issue to the district court, we decline to consider it on appeal.4
Finally, M2 Software argues that the district court improperly applied the Sleekcraft factors in evaluating whether M2 Communications’s use of the M2 mark would create a likelihood of confusion. We disagree. Although the district court erred in considering M2 Software’s sales and advertising in determining the “strength” of its mark,5 we find that the district court’s application of the Sleekcraft factors as a whole did not amount to an abuse of discretion. Further, because M2 Software’s federal registration and the incontestability of that registration go to the ownership of the M2 mark, they do not bear on the M2 mark’s strength and do not affect the likelihood of confusion analysis.6
M2 Software’s arguments raised in the questions presented or its reply brief but not argued in the opening brief are waived.7
The appeal as to Gaylord is moot, and must therefore be dismissed, because the district court dismissed the case against Gaylord for lack of jurisdiction.
