Winery and its owner, Gregory Kane, for trademark infringe-
ment. The district court ruled in Door Peninsula’s favor and
ordered Illinois River to pay damages. Illinois River now
appeals, but because it raises only arguments that were not
before the district court, we affirm.
                           I. BACKGROUND
    Door Peninsula Winery, a Wisconsin company, began
selling and distributing a spiced apple wine called “Hallowine”
in 1998. Sales were brisk, and Door Peninsula expanded
operations into Illinois later that year.
     The seasonal spiced apple wine market also beckoned to
Illinois River Winery and its owner, Gregory Kane. Illinois
River1 began selling its own Hallowine in 2005 and sought to
register the Hallowine mark with the Patent and Trademark
Office (“PTO”) in 2006. Door Peninsula initiated opposition
proceedings at the PTO and the Trademark Trial and Appeal
Board ruled in its favor, finding that Door Peninsula had
priority in the Hallowine mark.
   Illinois River continued to sell its Hallowine despite the
PTO ruling. Kane considered alternative names for the
seasonal wine, but ultimately decided that consumers would
prefer Hallowine.
   Door Peninsula filed suit against Illinois River in March
2012, asserting infringement of its common law trademark
rights and infringement of unregistered marks under § 43(a) of

   For concision, we will refer to Kane and Illinois River collectively as
“Illinois River.”
No. 13-3786                                                    3

the Lanham Act. In response, Illinois River asserted 27 affirma-
tive defenses. After some discovery, Door Peninsula moved for
partial summary judgment, seeking dismissal of Illinois River’s
affirmative defenses and a finding that Illinois River was liable
for trademark infringement to the tune of $508,864.26 in
damages. The district court granted the motion. Door Penin-
sula then moved to dismiss its remaining claims and for entry
of judgment. The district court granted that motion as well.
                         II. ANALYSIS
    Illinois River now appeals the district court’s decision,
arguing that it was defective for three reasons: (1) Kane is not
liable for damages in his individual capacity (2) damages
incurred before March 16, 2012 are barred by the applicable
statute of limitations, and (3) “Hallowine” is not a protectable
mark.
   The first two claims are easily dismissed. Illinois River did
not present them to the district court, and they are therefore
waived. Puffer v. Allstate Ins. Co., 

, 718 (7th Cir.
2012). A defendant cannot withhold arguments at trial and
then fault the district court on appeal for not addressing them.
   The third claim is also waived, but the analysis is a little
more complex. The district court did find that Door Peninsula
“established the validity of the HALLOWINE mark as a
protectable mark.” Illinois River seizes on this statement,
arguing that since the district court decided the mark was
protectable, it could not possibly have waived a protectability
argument.

   Presumably, the court ruled on protectability in response to
Door Peninsula’s brief, which marshaled both facts and law in
support of its argument that “Hallowine” was a protectable
mark. We will not find that an argument was adequately
preserved solely because a party’s opponent defended against
the argument, as Door Peninsula did here. Williams v. Dieball,

, 962 (7th Cir. 2013) (“to find that one party’s
argument was preserved because his opponent defended
against it out of an abundance of caution would be to punish
the opponent for being more thorough.”). The party making
the argument on appeal must have raised it before the district
court itself, which Illinois River failed to do. Its statement of
undisputed facts contained the results of Google searches for
“Hallowine,” and a vague assertion that “Hallowine” was
commonly used for fall special events. But Illinois River did
not argue protectability in response to Door Peninsula’s
motion for summary judgment. Arguments that are “underde-
veloped, conclusory, or unsupported by law” are waived on
appeal. 

. Illinois River’s argument was all
three and thus was waived.
   We make one final note: At oral argument, Illinois River
argued that it could not have waived its protectability argu-
ment because a finding that the mark was, in fact,
unprotectable would have gutted Door Peninsula’s prima facie
case. This is untrue. Summary judgment law “does not permit
a nonmovant defendant to delay pointing out claimed flaws in
the plaintiff's prima facie case until an appeal is under way.”
Resolution Trust Corp. v. Juergens, 

, 153 (7th Cir.
1992). The argument was waived; Illinois River cannot circum-

vent decades of our precedent requiring arguments be ade-
quately presented at trial.
                      III. CONCLUSION
   Illinois River did not adequately present any of its argu-
ments on appeal to the district court. They are all waived,
leaving us no alternative but to AFFIRM the district court’s
decision.
