The Polish Patent Office invalidated in part the right of protection for 100 R-156995 trade mark that was registered for Agencja Wydawnicza TECHNOPOL Spółka z o.o. for goods in class 16 such as posters, albums, almanacs, stationery, blocks, drawing blocks, brochures, magazines, charade journals, prints, forms, newspapers, calendars, calendars with tear loose, filing cards, cards, card-notices, postcards, comics, books, crossword puzzles, stickers, notepads, covers, stationery, bookmarks, drawing kits, notebooks. Technopol filed a complaint against this decision but it was dismissed by the Voivodeship Administrative Court in Warsaw in its judgment of 7 December 2009 case file VI SA/Wa 1677/09. Technopol decided to file a cassation complaint.

The Supreme Administrative Court in its judgment of 15 March 2011 case file II GSK 368/10 dismissed the complaint in part. The SAC held that the designation, which in fact is the number 100, is a highly informative sign for magazines and journals containing charades, and, as such may not be the monopolized by one entity that would like to use it for marking crosswords magazines. The Court noted also that adding to a trade mark any image does not yet give the sign a concrete distinctive character.
