The USPTO refused to register the mark MAGNUS
for "whiskey, gin and distilled spirits," finding the
mark to be primarily merely a surname under Section 2(e)(4).
Examining Attorney Kevin G. Crennan relied on search results
showing thousands of individuals with the surname MAGNUS, and on
evidence of applicant's promotion of its connection to Joseph
Magnus, an historical distiller. Applicant pointed to twelve
existing registrations for the word MAGNUS that were not refused
registration under Section 2(e)(4). How do you think this came out?
In re Jos. A. Magnus & Co., LLC,
Serial No. 87618554 (January 15, 2020) [not precedential] (Opinion
by Judge Thomas W. Wellington).

Results from three searches turned up several thousand
individuals with the surname MAGNUS. The Board found that this
evidence "shows that the relevant public has some exposure to
MAGNUS as a surname."
