TRADEMARK POLICY

HESK is a US and EU registered trademark of Klemen Stirn. Certain usages of the Trademark are fine and no specific permission from the author is needed:

- there is no commercial intent behind the use

- what you are referring to is in fact HESK. If someone is confused into thinking that what isn't HESK is in fact HESK, you are probably doing something wrong

- there is no suggestion (through words or appearance) that your project is approved, sponsored, or affiliated with HESK or its related projects unless it actually has been approved by and is accountable to the author

Permission from the author is necessary to use the HESK trademark under any circumstances other than those specifically permitted above. These include:

- any commercial use

- use on or in relation to a software product that includes or is built on top of a product supplied by author, if there is any commercial intent associated with that product

- use in a domain name or URL

- use for merchandising purposes, e.g. on t-shirts and the like

- use of a name which includes the letters HESK in relation to computer hardware or software.

- services relating to any of the above

If you wish to have permission for any of the uses above or for any other use which is not specifically referred to in this policy, please contact me and I'll let you know as soon as possible if your proposed use is permissible. Note that due to the volume of mail I receive, it may take some time to process your request. Permission may only be granted subject to certain conditions and these may include the requirement that you enter into an agreement with me to maintain the quality of the product and/or service which you intend to supply at a prescribed level.

While there may be exceptions, it is very unlikely that I will approve Trademark use in the following cases:

- use of a Trademark in a company name

- use of a Trademark in a domain name which has a commercial intent. The commercial intent can range from promotion of a company or product, to collecting revenue generated by advertising

- the calling of any software or product by the name HESK (or another related Trademark), unless that software or product is a substantially unmodified HESK product

- use in combination with any other marks or logos. This include use of a Trademark in a manner that creates a "combined mark," or use that integrates other wording with the Trademark in a way that the public may think of the use as a new mark (for example Club HESK or HESKBooks, or in a way that by use of special fonts or presentation with nearby words or images conveys an impression that the two are tied in some way)

- use in combination with any product or service which is presented as being Certified or Official or formally associated with me or my products or services

- use in a way which implies an endorsement where that doesn't exist, or which attempts to unfairly or confusingly capitalise on the goodwill or brand of the project

- use of a Trademark in a manner that disparages HESK and is not clearly third-party parody

- on or in relation to a software product which constitutes a substantially modified version of a product supplied by HESK.com, that is to say with material changes to the code, or services relating to such a product

- in a title or metatag of a web page whose sole intention or result is to influence search engine rankings or result listings, rather than for discussion, development or advocacy of the Trademarks

OTHER

This License Agreement is governed by the laws of Slovenia, European Union. Both the Licensee and Klemen Stirn submit to the jurisdiction of the courts of Slovenia, European Union. Both the Licensee and Klemen Stirn agree to commence any litigation that may arise hereunder in the courts located in Slovenia.

If any provision hereof shall be held illegal, invalid or unenforceable, in whole or in part, such provision shall be modified to the minimum extent necessary to make it legal, valid and enforceable, and the legality, validity and enforceability of all other provisions of this Agreement shall not be affected thereby.
