Quackmark is a project of DO Innovations SA. Where the site lists or writes about DO Innovations SA or firms affiliated with it, that relationship is disclosed on the page in question.

No legal advice

Everything on Quackmark is general information and education about intellectual property. It is not legal advice, it is not tailored to your situation, and reading it does not create an attorney-client relationship or any other mandate between you and DO Innovations SA.

IP rights are national. What is true in Switzerland may be false in the United States and only half true in the European Union, and deadlines in this field are unforgiving. Before you act, or decide not to, talk to a qualified professional in the country that matters to you. The IP Pages are a place to start looking.

Accuracy

We check what we publish, and the historical entries in the Brand Graveyard and the IP Park cite the decisions they rest on. Even so, this content is provided for information only: we give no guarantee that it is accurate, complete or current, and the law changes.

Genericide and every other question of validity is decided country by country and class by class. A mark described here as generic in one jurisdiction may be perfectly valid and enforceable in another. Nothing on this site should be read as a statement that any trademark is invalid, unenforceable or abandoned anywhere in particular.

Found a mistake? Please tell us: there is a documented route for it below, under Complaints, corrections and takedown, and we would rather hear from you than stay wrong.

Third-party trademarks

Quackmark names a lot of other people's brands, because that is the subject. All third-party trademarks, service marks, trade names, brand names and case names mentioned on this site remain the property of their respective owners. They are used here for identification, education, reporting and commentary only.

Nothing on this site implies any affiliation with, sponsorship by, or endorsement from those owners, and no third-party logos or brand artwork are reproduced: every brand name shown in the graveyard and the park is set in our own type or drawn as our own pixel art.

Complaints, corrections and takedown

If something on this site is wrong, or if you hold a right you believe it infringes, write to us before you instruct anyone. This route is faster than a letter from counsel, it costs nothing, and it works: most complaints we can imagine receiving are factual, and factual things get fixed.

Send it to hello@quackmark.com with “Quackmark - notice” in the subject line, and tell us:

• the URL of the page, and the exact wording or element you are writing about;
• the right you rely on: for a trademark, the registration number, the office and the class; for copyright, the work and your title to it;
• what is wrong, or why you say the use is unlawful;
• what you would like done: a correction, a qualification, an attribution, or removal;
• who you are, whom you act for, and where we can reach you.

What happens next. We acknowledge every notice within five working days and give a substantive answer within ten. A plain factual error we simply correct, usually the same week and without argument. Where we change something material after publication, the page says so and carries the date.

If it concerns the Brand Graveyard. A mark is only buried there if we could find no live registration for it anywhere. If we got that wrong (if your mark is registered and in force in any jurisdiction), send us the registration number and the office and we will amend or remove the entry. That is a factual question with a factual answer, and we would rather be told than be right.

What we will not do. We will not withdraw accurate reporting, or lawful commentary and parody, merely because it is unwelcome. Naming a brand in order to write about it is the entire point of an IP publication, and we believe it is permitted: referential and nominative use under Swiss, EU, UK and US law. But we would much rather discuss that by email than in front of a judge.

This procedure is offered in good faith as a practical first step. It is not a substitute for anybody's legal rights, it waives nothing on either side, and nothing in it is an admission. You are not required to use it before doing whatever else you are entitled to do.

Our content

The text, illustrations, pixel art, code and design of Quackmark are protected by copyright and other intellectual property rights and belong to DO Innovations SA unless stated otherwise. You are welcome to link to any page, to quote us with attribution, and to use the site freely for teaching and study.

Reproducing substantial parts of the site, or reusing it commercially, needs our written permission first. Ask, and we are unusually likely to say yes.

External links

This site links to IP offices, databases, publications and firms. Those sites are not ours: we do not control their content and we accept no responsibility for it. Links were checked when they were added; the web being what it is, some will rot.

Listings in the IP Pages are editorial and free. They are not a ranking, a recommendation or an endorsement, and they are not a statement about the quality of any firm. Verify a firm's credentials and standing yourself before you instruct anyone.

Advertising

Quackmark carries advertising, sold directly by DO Innovations SA. Every paid unit is labelled “Advertisement” and every paid link carries rel="sponsored". Sponsored articles are labelled as sponsored on the page and in the listing.

Advertising buys visibility. It does not buy a directory listing, a ranking, editorial coverage or a kind word. Terms and rates are available on request from hello@quackmark.com; see Collaborate.

Our own content. The Articles section is open to pieces from IP firms and vendors, and is not yet full. Articles written by DO Innovations SA or by its partners are our own editorial content, not paid placements, and are not labelled “Sponsored” because nobody has paid for them. Anything a third party pays for is labelled Sponsored on the page and in the listing, and its links carry rel="sponsored". Where the site lists or writes about DO Innovations SA or a firm affiliated with it, in the IP Pages directory for instance, that relationship is disclosed on the page in question.

Liability

To the fullest extent permitted by law, DO Innovations SA excludes liability for any loss or damage arising from the use of, or reliance on, this site or on any site linked from it. We do not warrant that the site will be available without interruption or free of errors.

Nothing in this notice limits liability that cannot be limited under Swiss law, including liability for personal injury or for intentional or grossly negligent conduct.

Data protection

How this site handles personal data is set out in the privacy policy. Cookies beyond the one that remembers your choice are set only with your consent; you can give, refuse or withdraw it at any time via Cookie settings in the footer of any page.

Governing law

Swiss law applies to this website and to this notice. Jurisdiction lies with the competent courts at the registered seat of DO Innovations SA in Lausanne, Switzerland, unless mandatory law provides otherwise: consumers keep whatever forum their own law gives them.
