If you registered a Czech trademark before 2019 and nobody told you the rule changed, you are not alone. Most owners still believe the office checks new applications against theirs. It stopped doing that seven years ago.
Here is the short version. Since 1 January 2019 the Czech Industrial Property Office does not compare your registered mark with anything. An application that copies it gets examined for distinctiveness and little else. Then it publishes in the office bulletin and waits three months for you to say something. If nobody speaks, the copy is registered and the cheap exit is gone.
What actually changed
An amendment to Act No. 441/2003 Coll. came into force on 1 January 2019. It scrapped section 6, which was the part that let the office refuse an application identical to an earlier registered mark for the same goods and services.
The office says it in its own 2019 annual report. It no longer determines ex officio whether the mark applied for is identical with an older trade mark. Three Prague law firms published notes on it that January and said the same thing in different words. The reason was alignment with Directive (EU) 2015/2436. EUIPO never examined earlier rights on its own motion either, so Czechia joined the club.
What it means in practice is simple. A competing application is examined on absolute grounds. Is it distinctive, is it descriptive, can the sign work as a mark at all. Nobody at the office opens your file and asks whether the new one looks like yours. That question was moved to you.
The clock, exactly
The opposition period is three months from publication of the application in the bulletin, the Vestnik. Section 25(1) of the trademark act. It cannot be extended and a missed deadline cannot be excused. The office repeats that wording in its FAQ and in its 2026 procedural guide for opposition proceedings.
An international registration designating Czechia runs on a slightly different clock. The three months start on the first day of the month after the mark was published in the WIPO Gazette. Section 48(2).
Who can object is wider than most people think. The owner of an earlier mark, the user of an unregistered sign, and anyone whose legally protected right the application could touch. Section 7.
What it costs is the part that should make you sit up. 1,000 CZK in administrative fees, item 138(b) of the fee schedule, and it has to be paid inside the same three months. The office does not remind you and does not chase the payment. No payment inside the window means the opposition is treated as never filed.
Now compare the next door. Once the mark is registered your options are a cancellation proposal or a declaration of invalidity. Those are proceedings with evidence, deadlines and representation, and they cost far more than 1,000 CZK. That is the whole argument for watching. You are not buying a fight. You are buying the cheap door before it closes.
Why a Czech watch has to look at Brussels too
An EU trade mark is valid in Czechia. So a watch that reads only the Czech register has a blind spot the size of the whole Union.
It works in the other direction as well. If someone files an EUTM that collides with your Czech name, nobody at the Czech office will call you. That application publishes in the EU Trade Marks Bulletin, the opposition window is three months from publication, and the same logic applies with a different address.
Our Czech watch reads the national register, EUTM marks and Madrid registrations designating Czechia at the same time. It runs at 9 USD a month, billed daily, so you pay for the days the watch is actually on.
What the local market charges
I read these off each vendor's own page today, 31 October 2026.
| Service | Czech coverage | Published price |
|---|---|---|
| IP Defender | Czech national plus EUTM plus Madrid | 9 USD a month, 108 USD a year |
| SEDLAKOVA LEGAL | Czech watch, monthly report reviewed by a lawyer | from 70 EUR plus VAT |
| infobroker | Czech watch, 12 months, 3 classes | 165 USD a year |
| MoniMark | Czech and other territories, human check on hits | a few thousand CZK a year, no number on the page |
Those prices are theirs, not mine. Check them yourself before you buy anything, the numbers move.
The real difference between the rows is who does the thinking. A lawyer reviewed report tells you which hit matters. A self serve watch tells you a hit exists and leaves the judgement to you and your attorney. Neither is wrong. They answer different questions.
Three questions that sort out any watch
Ask what registers it reads. If the answer is the Czech register only, ask what happens when an EUTM lands on your name.
Ask whether it matches similar marks or only identical strings. The common shape is a copy with one letter swapped, a different alphabet, or a character that looks the same on a screen and is not the same character. Over 22,000 character manipulation patterns are what our eleven detection layers read, and five AI watch agents score every new filing against them.
Ask how fast you hear. Three months sounds generous until the report arrives in month two.
What a watch will not do
A watch is information, not legal advice. We do not file your opposition, we do not decide whether two marks are confusingly similar, and we do not tell you whether to oppose. That call belongs to you and your attorney. What we do is make sure the application that looks like yours reaches you while the 1,000 CZK route is still open.
The per country pricing and the full market list are public, no form in front of them. The side by side against the enterprise vendors is on the comparison page, and the mechanics of the window in the US and the EU are in this piece on how fast a similar trademark deadline actually closes.
