TrademarkVision is an Australian startup that’s won contracts with the European Union Intellectual Property Office (EUIPO) and IP Australia. It’s aim is to develop algorithms that can detect and compare logos, helping you avoid trademark infringement.
It’s a bit like Google’s reverse image search, or TinEye, except more focused because the results are pulled from a database of trademarks.
It needs development with arranging results by closeness (as seen in the Adidas comparison), and it’s only as comprehensive as the amount of trademarks in the database, but searching by image is clearly better than searching by word, because a single mark can often be described using different terms.
There’s a 14-day trial on trademark.vision, or you can test it by searching EUIPO’s database with the free eSearch resource (EUIPO recently integrated TrademarkVision’s image recognition).
IP Australia hasn’t yet incorporated TrademarkVision into its search tool.
