3. Unauthorized Use of eCosCentric Marks.

3.1 General

Unauthorized use of the eCosCentric Marks or marks that are confusingly similar may constitute an infringement of eCosCentric's trademark rights and is strictly prohibited. Without the express prior written consent of eCosCentric, no eCosCentric Mark may be used in a manner that implies an affiliation with or sponsorship by eCosCentric.

3.2 Third Party Marks

Unless expressly authorized by eCosCentric in writing, third parties generally may not use any eCosCentric Marks as part of their company names, trademarks or logos. In other words, no person or entity may combine any eCosCentric Mark with any third party trademark without the express prior written consent of eCosCentric.

3.3 Internet Domain Names

No third party may create, register or attempt to register an Internet domain name that includes "eCos" or any of the eCosCentric Marks or any marks that are confusingly similar to the eCosCentric Marks in a way that is detrimental, i.e., harmful or damaging, to the value of any of the eCosCentric Marks, or to eCosCentric, its brand integrity, reputation or goodwill, as determined by eCosCentric in its sole discretion.

3.4 Damaging Use

The eCosCentric Marks may not be used in a manner or with respect to products that will decrease the value of the eCosCentric Marks or otherwise impair or damage eCosCentric's brand integrity, reputation or goodwill, including (without limitation) use in a manner that is unethical, offensive, disparaging, defamatory, illegal or in bad taste.

4. Guidelines for Proper Use of eCosCentric Marks

4.1 eCosCentric Marks

The current eCosCentric Marks are listed in Section 1 and Section 2 above. These lists will be updated from time to time at the sole discretion of eCosCentric. In addition, eCosCentric may, at its sole discretion, modify the eCosCentric Marks at any time. Please refer to this policy document periodically to ensure your compliance.

The absence of a trademark, service mark, trade name or logo from the lists above does not constitute a waiver of eCosCentric's trademark or other intellectual property rights.

4.2 Proper Trademark Use

Always use eCosCentric Marks as proper adjectives. A trademark is an adjective and must not be used as a verb or noun or in the possessive or plural forms. For example, when using eCos as a trademark, correct usage of the mark may be "The eCos Real-Time Operating System", "The eCos RTOS" or "The eCos Kernel".

The trademarks should always be correctly capitalized. Do not use all upper or lower case letters when referring to the trademarks. Incorrect: ecOS, ecoscentric, eCosPRO. Correct: eCos, eCosCentric, eCosPro.

eCosCentric Logos may only be used as stand-alone icons in accordance with this Trademark Policy, without any other third party logos and/or trademarks combined or associated with them, unless expressly authorised in writing by eCosCentric.

Any eCosCentric Logo shall only be used in conjunction with eCosCentric products and services, except as specifically agreed in writing by eCosCentric or in Section 1.1 above.

4.3 Provide Trademark Notice Symbols

When using any eCosCentric Mark, you should use the ® symbol. This symbol provides notice to third parties of eCosCentric's rights in its marks.

eCosCentric word marks must bear the trademark notice symbol ® in the first and most prominent usage of a mark and again in the first appearance of a word mark in the text or body of copy. Notice symbols must always appear with all eCosCentric Logos. Wherever possible, trademark notice symbols should be superscripted immediately after all eCosCentric Marks. Once proper trademark notice symbols are used, and a eCosCentric Mark is correctly attributed to eCosCentric (as further explained below), in permitted materials, it is not ordinarily necessary to mark subsequent appearances of the trademark in the same text.

4.4 Statement for Correct Attribution

All eCosCentric Marks that are used by third parties must be attributed to eCosCentric with our standard trademark attribution statement. The statement must always be a complete sentence, and ordinarily be placed in a visible place in the material referencing the eCosCentric Marks, e.g., on the copyright page, on the last page of the material, on the bottom of a web page, on a website's trademark policy page, or on product packaging. The following attribution statement must be used in all material referencing the eCosCentric Marks:

        [Insert relevant mark] is a registered trademark of eCosCentric Limited
        [Insert relevant marks] are registered trademarks of eCosCentric Limited

Trademark Policy FAQ

What is a trademark?

See Wikipedia's entries for trademark and service mark.

Why is eCosCentric enforcing the eCos trademark?

Anyone can provide an operating system, but trademark law prevents others from indicating that the source of the operating system was from the recognised free public distribution of eCos when it actually was not. eCosCentric is enforcing the eCos trademark to prevent any one party from duping the marketplace into believing that the eCos it is providing actually came from the recognised free public distribution of eCos when it did not. Trademarks are important because they help to prevent confusion in the marketplace by distinguishing the source of a product, in this case eCos. Should eCosCentric elect not to enforce the trademark and logo, these can fall into common use and thereby become difficult to defend should a party decide to use these to describe an operating system that is not derived from the recognised free public distribution of eCos, currently held on

For example, at one time, only Bayer could sell acetylsalicylic acid using the name Aspirin, and everyone knew the source of the product. But through lack of active enforcement of the trademark, it eventually fell into use as a generic moniker for the drug. In the 1920s, courts officially ruled that Aspirin was a generic name and that consumers did not associate the name with any particular producer. A second example is Hoover which has become so associated with vacuum cleaners in Britain as to become a genericized trademark. The word "hoover" (without initial capitalisation) is often used as a generic term for "vacuum cleaner". Hoover is also used as a verb, as in "Have you hoovered the lounge yet?".

Does enforcing the trademark conflict with the eCos license?

No. eCos is distributed under the terms of the GNU General Public License (the "GPL"), plus an exception to allow an application linked with the operating system to be provided for under a separate license. The GPL permits third parties to use and redistribute the underlying software under certain circumstances. The GPL does not provide any license or right to use the eCos Mark or Logo in any form or media. Thus, although a GPL licensee may redistribute the underlying software, a GPL licensee may not use the eCos Mark or Logo in any manner they choose. They can only do so in accordance with an agreement provided by the trademark owners, eCosCentric Limited.

To whom does this Trademark Policy apply?

This Trademark Policy applies to all eCos users, distributors and providers as well as eCosCentric's authorised partners, authorised resellers, licensees, customers, and users of eCosCentric's products and services, or products that incorporate eCosCentric's products or services, as well as other third parties who wish to use the eCosCentric Marks (referred to as "Third Parties" or "you"). However, except as expressly provided in Section 1.1, this Trademark Policy does not constitute a license, implied or otherwise, to use any eCosCentric Mark or the eCosCentric company name. Although we encourage use of the eCos Mark and Logo as provided in Section 1.1 above, generally, no person or entity may use any eCosCentric Mark without the prior, express written permission of eCosCentric.

By adhering to this Trademark Policy, you help eCosCentric to prevent confusion in the marketplace and to protect and enhance the value and integrity of the eCos Mark and Logo. eCosCentric appreciates your cooperation in this effort.

Why control the use in publications and presentations?

The rules for use of the eCosCentric Marks in publications are aimed at avoiding eCosCentric or the eCos open source project appearing to sponsor, endorse, or be directly connected with the work in some way.

What should I do if I have further questions, or suspect a violation of this policy?

You should email eCosCentric.
