What this record means
The record shows the “JACK” application is dead – it was expressly abandoned on August 14, 2008 by the applicant GRUNER + JAHR AG & CO. KG, a German corporation, and it never moved beyond the Principal Register filing. The only listed goods are a “Magazine directed toward young men” in International Class 016, so the closest area of concern would be any other publication aimed at the same audience that uses the word JACK in its title or branding. The record does not give the owner control over every use of the word JACK in unrelated products or services. There is no Supplemental Register entry, and the prosecution history simply tracks routine suspension checks and the final express abandonment notice. No oppositions, cancellations or court actions appear in the supplied history. I'd treat this as a modest concern if you plan a magazine for young men with a similar name, but the risk drops sharply for other types of goods or services.
