Patent examiner: Iurchenko (Romanski) is not inventor of G-vibe.

The United States Patent and Trademark Office rejected G-vibe patent application of Ievgen Valeriyovych Iurchenko aka Jack Romanski. In the United States, all patents must have a patent examination. Before that, Iurchenko received declarative patents only for which expertise is not required. This decision means that there is a lack of novelty for all Gvibe patents and each can be annulled same as the Russian patent for a utility model 140434 was annulled in 2015.

Full text of the final rejection available at the application number: 14/263755.

The patent for the invention SplitDILDO and other split shaft sex toys was issued to Sergie Topolev  on Sep 1, 2015. The first patent application was filled him Nov 26, 2009.

A few years ago Iurchenko said: “The company has stated that even before the product appeared on the market which was in September 2012 G-vibe had been already protected by the US patent.” and “I remember the day when the idea of G-vibe appeared in my head. And I can responsibly state that it was not influenced by someone else’s inventions in any way.”

Fun Factory forced Fun Toys to stop selling Gjack and change the name to FT London.

Adult manufacturers Fun Factory GmbH and FunToys, LLC (formerly Fun Toys, now FT) have reached an agreement regarding FT’s Gjack vibrator.

According to a press release, “both manufacturers would like to clarify that the Gjack despite its appearance and promoted product features, in combination with the brand name Fun Toys, was manufactured by FT, and in no way related to Fun Factory.”

To avoid further confusion with Fun Factory’s Big Boss vibrator, the two manufacturers have agreed that FT will remove the Gjack from the market, filling no new orders past Dec. 31, 2016.
