The Canadian Intellectual Property Office (“CIPO”) has begun accepting trade-mark applications for sound marks. The application for registration should: (a) state that the application is for the registration of a sound mark, (b) contain a drawing that graphically represents the sounds, (c) contain a description of the sound, and (d) contain an electronic recording of the sound. CIPO is only accepting sound recordings in MP3 or WAVE format, limited to 5 MBs in size, and recorded on a CD or DVD.
