As followers of Naavi are aware, Naavi had introduced a service lookalikes.in based on his patent application around 2002. The objective of the service was to provide a third party disclaimer on the presence of confusingly similar domain names.
For example the accompanying note on the website indicates that Naavi.org does not have relationship with the site navi.co and related websites.
It is advisable for the other sites also to display similar disclaimers so that mutual distrust and trademark related disputes can be avoided.
This service was introduced long time back but was not pursued. The patent application also had to be abandoned subsequently.
The reason why this service was contemplated was to prevent the potential misleading information that an alternate website could give to a visitor. As a part of the compliance of a website it is considered that a website owner needs to take some reasonable steps to warn the visitors that there could be alternate sites with similar names that the visitor should be wary of.
Hence this is made part of the WebDTS service in whatever form it can be made available at present. Some improvement of presentation may be expected.
PS: Requests for WebDTS can be booked through FDPPI website.
