Intellectual Property --a work or invention that is the result of creativity, such as a manuscript or a design, to which one has rights and for which one may apply for a patent, copyright, trademark, etc. --Oxford Languages
Patent --A patent is a right, granted by the government, to a person or legal entity (partnership or corporation). A patent gives its holder the right to exclude others from making, using, or selling the invention “claimed” in the patent deed for 20 years from the date of filing. Once the patent expires, the invention covered by the patent enters the public domain and can be used by anyone. The scope of a U.S. patent is limited to the borders of the United States and its territories.

Trademark --The term trademark refers to a recognizable insignia, phrase, word, or symbol that denotes a specific product and legally differentiates it from all other products of its kind. A trademark exclusively identifies a product as belonging to a specific company and recognizes the company's ownership of the brand. Trademarks are generally considered a form of intellectual property and may or may not be registered.

Copyright -- A form of protection provided by the laws of the United States for "original works of authorship", including literary, dramatic, musical, architectural, cartographic, choreographic, pantomimic, pictorial, graphic, sculptural, and audiovisual creations. "Copyright" literally means the right to copy but has come to mean that body of exclusive rights granted by law to copyright owners for protection of their work. Copyright protection does not extend to any idea, procedure, process, system, title, principle, or discovery. Similarly, names, titles, short phrases, slogans, familiar symbols, mere variations of typographic ornamentation, lettering, coloring, and listings of contents or ingredients are not subject to copyright.
