BTW, here's the 30-second IP summary. (High-level, omitting nuances) Just so some future discussions may be a bit more enlightened.
4 basic types of IP:
Copyright: Right to prevent others from copying and/or distributing creative works, applies to any tangible creative work (including drawings/paintings/sculpture, software code, literary works, films, recorded music, etc., but NOT things like live performances or collections of information). Protection is automatic now but copyrights should be registered to assert rights in court.
Trademark: Word, phrase, logo, or combination that identifies the source of goods or services. (Sometimes a color or a sound can be a TM too). Trademark rights arise from use, but you can also register TMs on the Federal Register and in other countries, which give you stronger/enforceable rights. A 'TM' next to a word/phrase/logo means you are using the thing as a trademark; the (R) means the trademark is registered. Using (R) for a non-registered mark is illegal.
Patent: A limited monopoly to prevent others from making, using, offering for sale, or exporting an item (or practicing a method) that is covered by one or more of the claims of a patent. Patents are enforceable for roughly 20 years after the filing date, at which time they become public domain. Patents cannot be renewed or extended. An invention must be both novel (new) and non-obvious to be patentable. If it's already 'out there' or just a trivial/obvious variation of an existing item, it can't be patented. You can also get patents in other countries. Patents don't grant the owner/assignee/licensee any right to practice their own invention, but only to prevent others from doing so.
Trade secret: information that is maintained confidentially by a business using reasonable efforts to avoid public/unauthorized disclosure. Independent 3rd-party discovery (through legit means) of a trade secret does not violate any laws. Using confidential info from a former employer in a new job would (generally) be a violation of trade secret laws.
Patents, trademarks and copyrights fall under Federal law. (Some "common-law" trademark rights arise under state laws.) Trade secrets are directly protected under state law only.
