The three conditions for protection, what cannot be patented, and choosing between two titles with different thresholds.

A patent covers a technical solution — a product or a process — that solves a defined problem by applying natural laws.

## Three conditions for a patent

**Novelty.** Not disclosed publicly in any form anywhere in the world before the filing or priority date. This is the condition applicants most often destroy themselves: a social post, a demo, a conference paper or a public fundraising pitch can each sink it.

**Inventive step.** Not obvious to a person of ordinary skill in the relevant field. The hardest condition and the reason most applications are refused.

**Industrial applicability.** Capable of being manufactured or applied repeatedly with stable results.

## Utility solutions — same subject matter, lower bar

A utility solution requires only **novelty** and **industrial applicability**, not an inventive step, provided the solution is not common general knowledge. Patents run 20 years from filing; utility solutions 10. Neither can be renewed and both carry annual maintenance fees, but the grant rate for utility solutions is markedly higher.

In practice, a patent application refused for lack of inventive step can often be redirected to a utility solution. If your improvement is real but moderate, filing for a utility solution directly can save both time and money.

## What cannot be patented

Scientific discoveries and pure principles; methods and systems for economic organisation and management; educational and training methods; animal training methods; language, information and classification systems; **computer programs** (software is protected by copyright, though a technical solution using software may qualify where the substance lies in the technical solution); ways of presenting information; purely aesthetic solutions (that is design territory); plant and animal varieties and essentially biological processes for producing them; and methods of prevention, diagnosis and treatment for humans and animals.

## The core bargain: exclusivity for disclosure

A patent is a deal with society. You get 20 years of exclusivity; in exchange you must disclose the solution fully enough for a skilled person to reproduce it. Once the application publishes, the world can read how you did it.

This is why a trade secret is sometimes the better route. If your solution resists reverse engineering and you can keep it confidential, a trade secret lasts indefinitely with no disclosure at all. But if someone independently develops it and files first, you can lose both ways.

## Term and maintenance

A patent runs from grant until the end of **20 years from the filing date**. Note the arithmetic: examination time eats into the effective term — an application taking four years to grant leaves sixteen years of exclusivity. **Annual maintenance fees** are due; missing one is the commonest cause of early lapse.

## 2026 updates

From 1 April 2026, substantive examination of patent applications is capped at **7 months** from publication, and eligible applications may request **accelerated examination** under Article 14a of the amended Decree 65/2023.

Decree 100/2026/ND-CP also addresses how industrial property rights arise where the subject matter was created **using an AI system** — the AI is not a rights holder, but a person using AI as a tool with a substantial creative contribution may be recorded as the inventor.
