A patent is a government-granted right that lets an inventor stop others from making, using, selling, or importing their invention without permission, usually for a limited time (often 20 years from filing for utility patents).
Generally, new and useful processes, machines, manufactured items, compositions of matter, or improvements to existing ones. Some countries also allow design patents (for how something looks) and plant patents.
Abstract ideas, laws of nature, natural phenomena, and (in most jurisdictions) things like mathematical formulas on their own, or inventions that are purely mental processes without practical application.
Typically three: novelty (it must be new), non-obviousness/inventive step (it can't be an obvious tweak to existing tech), and utility/industrial applicability (it must actually work and do something useful).
Utility patents usually last 20 years from the filing date. Design patents often last 15 years from grant (varies by country). Maintenance fees are usually required to keep it in force.
A patent protects inventions and how things work; a trademark protects brand names, logos, and identifiers; a copyright protects original creative works like writing, music, or art.
Not legally required, but patent applications are technical and legally precise, so most people use a registered patent attorney or agent to avoid costly mistakes.
A provisional application is a cheaper, informal filing that secures an early filing date and gives you 12 months to file a full non-provisional application. It's never examined or granted on its own.
Costs vary widely by country and complexity - anywhere from a few thousand dollars for a simple provisional filing to tens of thousands for a full utility patent with attorney fees, especially if filed internationally.
It varies by country and patent office backlog, but typically 1 to 3+ years from filing to grant.
Prior art is any evidence that an invention was already known before the patent application - earlier patents, publications, products, or public disclosures. It's used to test novelty and non-obviousness.
No - you can't patent a mere idea. You need a concrete, workable invention with enough detail that someone skilled in the field could actually build or use it.
You (the patent holder) can sue for infringement, seeking damages and/or an injunction to stop the infringing activity. Patent offices don't enforce patents themselves - enforcement is up to the owner.
No, patents are territorial - a patent granted in one country only protects you there. To get broader protection, you'd file in multiple countries or use systems like the PCT (Patent Cooperation Treaty) to streamline international filing.
Publicly disclosing your invention (talking about it, publishing, selling it) before filing can hurt or destroy your ability to patent it in many countries, since it may count as prior art against your own application. Some countries (like the US) offer a limited grace period, but many others don't.
