4.1Trademarks & filing
The essentials in 30 seconds
- A trademark = a distinctive sign (name, logo, slogan); in most countries, the exclusive right is acquired by filing with an office, not by mere use.
- Principles: speciality (designated classes), territoriality (covered countries), availability (no prior rights), distinctiveness (neither descriptive nor deceptive).
- Reflex: check availability BEFORE choosing a name or domain — a third party can file 'your' name if you have not.
Running mini-case — Yacine protects his brand name
Yacine launches an accessories brand and has used its name for months without filing it. Before printing packaging and a domain name, he checks availability (similar earlier trademarks, variants) then files for the right classes and the right territory. His brand becomes a clear, enforceable right — the first asset he protects, before his content, his website, his online terms and his AI uses.
This same case runs through the lesson, the diagram, the script and the 48h challenge — and continues in 4.2, 4.3, 4.4 and 4.5.
1. Rights arise from filing
A trademark is a sign (name, logo, slogan) used to distinguish your goods or services from competitors'. The key point: in most countries, you only acquire an exclusive right by filing it with an office (e.g. the INPI in France) — use alone protects poorly, if at all.
Filing confers a monopoly: the right to use the trademark and to prohibit an identical or similar sign for similar goods, in the territory covered. Yacine thus moves from a merely used name to a defensible name.
2. Speciality, territoriality, availability
Speciality: the trademark is only protected for the classes of goods or services designated at filing (the same word can coexist in different fields). Territoriality: it only protects the territory or territories where it is filed.
Before any filing, two checks: availability (no similar earlier trademark for close goods) and distinctiveness (a purely descriptive or generic sign risks refusal). A registered trademark gives an offensive right (suing for infringement) and security (preventing a third party from filing your name before you).
3. Maintaining the trademark
Protection does not stop at filing: renew on time, genuinely use the trademark, monitor infringements. Yacine notes the deadline, keeps evidence of use and gets support as soon as the stakes become real.
Since offices and rules vary by country, he checks the law applicable to his markets instead of applying a foreign framework as is.
🔎 Concrete example — Check before choosing (Yacine case)
Upstream availability.
Before choosing a name, a logo or a domain name:
Yacine searches for similar earlier trademarks (name AND variants, phonetic lookalikes).
→ launching an identity then having to change everything costs infinitely more.Result: a name protected by a clear, enforceable right.
Reflex: designate the right classes and the right territory at filing.
Section vocabulary
- Trademark
- A sign (name, logo, slogan) used to distinguish a company's goods or services from those of competitors.
Simple example: The name and logo Yacine files for his accessories.
What it is not: a mere idea or a name used without filing (weak or no protection).
Reflex: ask 'does my sign really distinguish my goods?'.
- Filing / registration
- The formality with an office which confers the exclusive right in the trademark; use alone protects poorly or not at all.
Simple example: Yacine files with the competent office instead of merely using his name.
What it is not: publishing his name on his website believing he is protected.
Reflex: long use never replaces filing.
- Speciality principle
- A trademark is only protected for the classes of goods or services designated at filing.
Simple example: Yacine targets the classes of his accessories, not every field.
What it is not: believing one filing automatically covers all sectors.
Reflex: list your real goods before choosing classes.
- Territoriality
- A trademark only protects the territory or territories where it is filed.
Simple example: Yacine files for the countries where he actually sells.
What it is not: believing a national filing protects the whole world.
Reflex: link each targeted market to a matching filing.
- Availability / distinctiveness
- Before filing: check that the sign is free (no prior rights) and distinctive (neither descriptive, generic nor deceptive).
Simple example: Yacine discards a descriptive name and a name already taken in his class.
What it is not: filing directly with no search at all.
Reflex: check before choosing, not after.
In practice — In practice — Protecting your name and identity with a trademark
- Before choosing a name, logo or domain name, check its availability (no similar earlier trademark, variants included).
- Make sure the sign is distinctive (neither purely descriptive, generic nor deceptive).
- File the trademark with the competent office, designating the right classes of goods or services and the right territory.
- Maintain it: renew on time, genuinely use it, monitor infringements; get professional support for significant matters.
Ready-to-say script — asking for a prior-rights search (1 min)
'Before finalising our name, can you check its availability — similar earlier trademarks, variants and targeted classes — and tell me whether it is distinctive? We will only file after your green light.'
Say it to a lawyer or IP counsel: check before choosing, not after.
Copy-paste template — trademark checklist before filing
PLANNED NAME / LOGO: _______________
AVAILABILITY CHECKED (prior rights + variants): _______________
DISTINCTIVE (neither descriptive, generic nor deceptive): _______________
TARGETED CLASSES: _______________ / TERRITORY: _______________
COMPETENT OFFICE + SUPPORT: _______________Starting creator
Small budget: at minimum, check availability before buying the domain and printing — changing a name costs more than checking it.
SME in Algiers
Yacine has the competent local office (INAPI) and its classes checked with a local professional instead of applying the French framework as is.
Domain name
Owning the .com or .dz is not filing: the domain does not stop a third party from filing the matching trademark.
Commissioned logo
Combine with the assignment of rights (4.2): the designer assigns his rights, then you file the logo as a trademark.
✓ Best practices
- Check availability BEFORE choosing a name or domain.
- File for the right classes and the right territory.
- Maintain the trademark (renewal, genuine use, monitoring).
✗ Common pitfalls
- Believing long use protects as much as filing.
- Choosing a purely descriptive or generic sign (not distinctive).
- Letting a third party file 'your' name before you.
Key takeaways
- A trademark distinguishes your goods or services; in most countries, RIGHTS are acquired by FILING, not by mere use.
- Principles: speciality (designated classes), territoriality (countries covered), availability (no prior rights), distinctiveness (neither descriptive nor deceptive).
- A registered trademark gives an offensive right (suing for infringement) and security (preventing a third party from filing your name before you).
- Check availability BEFORE choosing a name or domain; maintain the trademark (renewal, use). Offices and rules vary by country.
48h challenge — apply it tomorrow
List your name, logo and domain: for each, note whether it is filed, checked or to check, with the targeted classes and territories. Ask a professional what is missing first. 20 minutes is enough.
- I can explain why rights arise from filing, not use.
- I can cite speciality, territoriality, availability and distinctiveness.
- I listed my signs and their status (filed, checked, to check).
Frequently asked questions
I have used my business name for years: am I protected without filing it?
Probably far less than you think. In most countries, the exclusive right in a trademark is acquired by filing, not by use. Prolonged use may confer certain rights (trade name, signboard, unfair competition), but these protections are weaker and harder to enforce. The real danger is twofold: a third party can file 'your' name and cause you enormous difficulties, and without a trademark you are poorly equipped against copies. If your name has value, filing it turns weak protection into a clear, enforceable right — after checking it is still available.
How can I be sure that the name I want to use is available?
You can never be 100% sure, but you greatly reduce the risk with serious upstream checks: search office trademark databases (name AND variants, phonetic lookalikes), extend to search engines, trade registers, domain names and social media, then check distinctiveness. Judging whether a sign is 'similar enough to create confusion' is a subtle analysis: as soon as the stakes are real, have an in-depth prior-rights search done by a professional. Golden rule: check before choosing, not after.
Yacine has used his name for a year without filing it; a third party files a close name for the same goods. What must he understand first?
