Antevo Trademark

Screen a brand name against the live trademark registers. Free, no account. Returns every mark near it with a similarity tier, plus which registers were checked. This is the first thing to run when someone asks 'is my name taken'.

Which Nice classes a business like this files in. Free, no account, no database. The question people cannot answer for themselves: not "is my name taken" but "taken in WHAT". Nice has 45 classes and the numbering is opaque — software you download is class 9, software you log into is class 42, and selling other people's goods is class 35 whatever the goods are. Filing in one and not the other is the most expensive routine mistake in the process. Run this BEFORE screen_mark when someone describes a business rather than naming a class: the classes it returns are what makes a screen mean anything. Relay the reasoning, not just the numbers, and keep the closing caveat — this reports how similar businesses file, and their counsel decides what they actually file.

Who a holder is and how they file — the read on an adversary. Free. Computed from their whole register book: how much of it they let lapse, whether their marks cluster where they trade or spray across unrelated classes, and the leverage that gives counsel. Present the evidence, not just the label — and never call anyone a squatter; that is a legal conclusion we do not assert.

How long you have to oppose a filing in a given trademark office, and from when. Twenty registers, each with the provision the window comes from. The trap this answers: most offices run opposition BEFORE registration, from publication of the application, but a minority — Switzerland, Germany, Japan, Sweden — register the mark first and run the window from publication of the REGISTRATION. Applying one office's rule to another invents a deadline that never existed. Accepts a country name, an office name or a two-letter code ('japan', 'JP', 'EU').
