The “crowded field” argument is a common strategy used to overcome likelihood of confusion refusals: if an applicant points to enough similar third-party marks, the Board may conclude that each mark is entitled to a narrow scope of protection such that even minor differences will suffice to prevent consumer confusion. In In re Mario’s LLC, Serial No. 98460342 (T.T.A.B. Jan. 27, 2026), however, the TTAB held that the applicant’s third-party evidence didn’t meaningfully weaken the cited mark, and thus affirmed the refusal.
