Patent

A patent is a property right granted by a government to an inventor to exclude others from making, using, or selling an invention for a limited time (usually 20 years).

No. Ideas alone are not patentable. You must have a specific, technical description of how to implement that idea—a “reduction to practice.”

To be eligible, an invention must be:

1. Novel: It must be the first of its kind in the world.
2. Non-obvious: It shouldn’t be a simple change an average expert could think of.
3. Useful: It must have a practical, functional application

Abstract theories, mathematical formulas, laws of nature, physical phenomena, and purely artistic works (which are for copyright) are generally excluded.

In 2026, the answer is “sometimes.” You generally cannot patent the code itself, but you can patent the method or process the software performs if it provides a “technical solution to a technical problem.”

It’s a placeholder that lets you secure a filing date (establishing “Patent Pending” status) for 12 months. It is cheaper and easier to file than a full application, giving you time to test the market.

Usually, the inventor owns the rights unless they have signed an employment contract that “assigns” those rights to the company. Most tech and research jobs include these clauses.

It means a patent application has been filed but not yet granted. It serves as a warning to competitors that they could be sued for infringement once the patent is officially issued.

No. Most patent offices only require a detailed written description and drawings that would allow someone else in your field to build the invention.

Legally, yes. Practically, it is extremely risky. Patent “claims” (the legal sentences defining your invention) are highly technical; one wrong word can make your patent worthless in court.

No. Patents are territorial. A US patent only protects you in the US. However, the Patent Cooperation Treaty (PCT) allows you to file one application to “reserve your spot” in over 150 countries simultaneously.

Typically, you have 12 months from your first “home” filing to file in other countries while still claiming your original filing date.

Not necessarily. Someone else might have a broader patent that covers a part of your invention. You might need to license their technology to use your own invention.

You must sue them in civil court. The government does not “police” patents for you; it only gives you the legal tool to defend yourself.

Yes. Competitors can “challenge” a patent’s validity by proving to the patent office or a court that the invention wasn’t actually new or obvious at the time it was filed.
