Patent & trademark

Terms related to patent and trademark applications and infringement litigations. A patent is a form of intellectual property and associated rights granted by a sovereign state to an inventor or their assignee for a limited period of time. A trademark, on the other hand, is a distinctive mark or name used by an individual or business organization to identify and distinguish its products or services from those of other entities.
