You're an Entrepreneur

The most important rule: there is no "grace period" in Europe. If you show your invention publicly – at a trade fair, on sale, in the media, or even in a "soft launch" in Poland – before filing a patent application, you lose the right to a patent in Poland and across the EU. So there is only one correct order: file first, launch later. Before filing, check that you are not infringing third-party rights (a freedom-to-operate search) and that the idea is genuinely new. Also take care of your trademark, protection of your product's design, and written assignments of rights from your collaborators.

No. An entry in the National Court Register (KRS) lets you trade under a given name, and a domain registration only gives you the right to use that address – neither stops a competitor who starts selling under a similar name. An exclusive right to your brand comes only with trademark registration: at the Polish Patent Office (UPRP) for Poland, or at the European Union Intellectual Property Office (EUIPO) for the entire EU. The "first come, first served" rule applies, so it pays to file early. Protection lasts 10 years and can be renewed indefinitely.

Knowledge that is not formally protected leaves the company together with the employee. For know-how to count as a trade secret, three conditions must be met: the information is confidential, it has commercial value, and you actually protect it. That "actual protection" means concrete measures: non-disclosure agreements (NDAs), the right clauses in contracts, access limited to those who genuinely need the knowledge, marking materials as confidential, and orderly offboarding procedures. If the solution can be easily copied or simply "carried away in someone's head," consider a patent – it protects you regardless of the team's loyalty.

An investment – provided it serves a specific business goal. Research on startups shows that companies with patents grow faster and raise capital more easily: higher valuations and better odds of landing an investor or an acquisition. Well-chosen protection builds exactly the kind of company value that buyers and investors look for first. On the other hand, a patent filed "just in case," with no idea of whom or what it is meant to protect, can be a cost with no return. So start with the question: what business outcome is this protection supposed to deliver – and only then pick the tool.

Competitors leave traces in public registers – and they are worth reading. Patent applications are published, so they show what your rivals are working on (with a delay of about 18 months). Free databases such as Espacenet or Google Patents are enough for a general review, while paid tools (e.g., PatSnap, Questel) offer automatic alerts on new filings. It is also worth monitoring trademark and design registers to catch similar brands early. Raw data alone is not enough, though – the value comes from regular analysis: who is entering the market, where the technology is heading, and where the white spaces are.

A patent is not your only weapon. A product's appearance can be protected as a design – in the EU even without registration, automatically for 3 years from when it is first shown on the market – and code, graphics, and text are protected by copyright. If a competitor copies your product closely and misleads customers, the Polish Unfair Competition Act helps (so-called slavish imitation), and the first step is usually a cease-and-desist letter. Your head start works for you too: rapid iteration and a strong brand make it hard for competitors to close the gap. It is worth checking with a patent attorney which of these grounds you can actually rely on.

Start early – ideally 1–2 years before the transaction – and get one thing right above all: certainty that the company actually owns its IP. Missing written copyright assignments from B2B contractors or founders are a classic "minefield" that can drag down the valuation. Put your registrations (trademarks, patents, designs) in order in the right markets and resolve open-source license issues. Investors and buyers value formal protection, so wherever possible, "dress" valuable confidential know-how in registered rights. Finally, check whether the portfolio actually blocks competitors – because that is exactly what due diligence will ask about.

A patent requires disclosing the invention in full – in return you get 20 years of exclusivity; secrecy requires disclosing nothing and can last for decades (like the Coca-Cola recipe), but only as long as you genuinely protect it. Three questions decide. Will you detect that a competitor is copying you? If the solution runs hidden on their servers and you cannot prove it in court, secrecy is the better choice. Can the product be easily taken apart and examined? If so, secrecy is an illusion and patenting is the safer route. Will competitors quickly come up with it on their own? If so, a patent gives you more reliable protection.

Yes – in a great many cases you can obtain patent protection for software and artificial intelligence solutions. In Europe, "technical character" is what counts: you can patent a solution that produces a specific technical effect, not a bare business idea. The code itself is additionally protected by copyright – automatically (as long as it was written by a human rather than generated automatically through vibe coding).

Usually yes – the technology market is global, while IP rights are territorial: a Polish patent does not protect you in the US or in Germany. There are convenient routes, though: a European patent covers many countries in a single procedure, and an international PCT application "reserves" the option of obtaining patents in over 150 countries for about 30 months, giving you time to decide and to raise funding. Budgets are often limited, so choose your key markets – but do it before the public launch, otherwise you lose the right to a patent in Europe.
