Most trademark watch quotes are sold on coverage. How many registers, how many countries, whether WIPO is thrown in. Almost never on the one thing that decides whether you actually get warned, which is what the software compares when a new application lands.
I have spent the last few weeks reading provider pages while working on what a watch costs in Europe. The pattern that came back was consistent. The cheap end of this market no longer does exact matching only. Almost all of it stops short of the same place.
A filing almost never copies your name
If someone files a mark that helps them, it is rarely your word with the same letters in the same order. Copying exactly is the one version an examiner kills in five minutes and that your own eyes catch in a second. What people actually file is the version that looks familiar, sounds familiar, or sits inside a longer name, and still survives a first look.
Four shapes cover most of it.
Same sound, different letters. Kuikset for Kwikset. Fone for Phone. In a shop, on a radio ad, in a customer's memory, those are one brand.
Same look, different characters. A Cyrillic a instead of a Latin a. A zero instead of an O. A doubled letter. A capital I instead of a lowercase l. At the size a logo actually gets printed, the two are indistinguishable, and to a search box they are two unrelated strings.
Your mark inside a longer one. NORD becoming NORDVIK, or TRI-NORD, in the same class, on the same shelf.
Same image, no word at all. A logo filed as a device mark with no text. A word search sees nothing there, because there is nothing to compare.
What each shape needs to be caught
An exact match is a database lookup. It is cheap because it is easy, and it is why a feed that only does exact matching can be sold for almost nothing.
Fuzzy matching on spelling is now table stakes. One provider publishes its gate in the open and it is readable. Edit distance capped at a quarter of the shorter string's length. A phonetic key so that two spellings of one sound collide. Word overlap for tokens of four characters or more. A class filter on top of all of it. That is a real watch and it will catch a lot.
Sound needs its own layer though, and that layer is not free. Two spellings of the same sound have an edit distance that depends entirely on how they were spelled. So a spelling threshold cannot be tuned to catch both Kuikset and Quikset without also dragging in a pile of noise. It is a different algorithm doing a different job.
Confusable characters are a different problem again. That one is not about a score, it is about the substitution space. There are more ways to write a letter than there are letters. Every alphabet, every script that renders like Latin, every lookalike digit set, doubled and dropped letters, and all the combinations that fall out of those. Either the software has enumerated that space and compares against it directly, or it is hoping a statistical similarity score happens to land high on a filing that is visually identical and textually different. Sometimes it will land high. That is not the same as a system.
Images are the fourth, and the most expensive to run. It takes four neural networks to look at a new device mark and say it resembles yours in the way an ordinary observer would. A text only pipeline has nothing to run on an image at all.
The six tests, and you can run them on anyone
Here is what I would do before paying for any watch, ours included. Take your own mark and write down six fake filings that should each produce an alert. Then ask the provider to run them as a test.
One. A single letter swapped for one that sounds the same. Your mark with an f where the ph goes, or a k where the c goes.
Two. A single Latin letter swapped for the Cyrillic character that looks identical. This is the cheapest test to run and the one that fails most often, because the string no longer contains your mark at all.
Three. A doubled letter, or a dropped vowel. Two characters of noise to a distance measure, identical on a shelf.
Four. Your mark embedded inside a longer word, filed in a class you actually sell in.
Five. A translation, if your mark means something in another language.
Six. A device mark carrying your logo with no text at all.
Score each one. A provider that passes one, two and six is doing real work. A provider that passes all six is rare. A provider that will not run the test has told you something as well.
Ask for the results in writing, with the application numbers each test would have generated. It is an afternoon of their time and it tells you more than any brochure.
What we publish about our own stack
Every plan, including the cheapest country at six dollars a month, runs five specialized AI watch agents and eleven detection layers. Two of those layers are phonetic, and they are AI rather than a fixed key. Four are visual, meaning four separate networks reading device marks. Some of the layers are built for exactly the second test above, where the filing is visually your mark and textually is not, and one of the things they compare against is a library of more than 22,000 character fraud patterns.
I am not going to tell you that means we catch everything. Nothing does, and any provider who tells you otherwise is selling you a feeling. What I will say is that those layers run on a six dollar watch the same as on a two hundred dollar one, because countries are what we meter, not detection.
The honest limit
A watch tells you that a filing exists which resembles yours. It does not tell you whether that filing is a threat, whether you can stop it, or whether you should try. That is a legal judgement and it belongs with your attorney.
Which is why the reviewed tiers exist and cost what they cost. A law firm watch that includes a person reading the hits for you is a different product from an alert feed, and the gap between the two prices is judgement, not software.
Where the software earns its money is the hour before that conversation. Finding out in week two and finding out in week fourteen is the difference between a cheap opposition, an expensive coexistence, or nothing left to do at all.
Our prices are per country, published, with no annual contract and no sales call. The whole list is on the pricing page and it starts at six dollars a month.
This is not legal advice. A watch tells you that a filing exists. What you do about it belongs with your trademark attorney.
