In the field of intellectual property, the interplay between trade marks and patent claims is very rarely discussed, given the distinct scope of protection provided by each. In Australia and New Zealand, patent examiners tend to raise an immediate clarity objection when a trade mark finds its way into a claim. This concern arises from the fact that a trade mark is an identifier of origin, and products bearing them can undergo variations across jurisdictions and time frames. This makes the intended scope of the claim unclear in many situations. Consequently, Australian and New Zealand examiners commonly raise objections based on clarity when trade marks feature in patent claims during the examination process.
