It's usually hard to get back a domain name made of initials. The jcm.com decision shows it again.
Furthermore, in this case "[t]he Respondent has demonstrated to the satisfaction of the Panel that:
1. his initials are JCM;
2. he acquired the Domain Name for use by his family business JCM Industries Inc;
3. until December 2001 the Domain Name was used for email purposes both by the Complainant and by the business; further, it was used by the business to connect to a website at “www.jcm.com”;
4. the family business applied for and obtained a service mark registration of a device mark, the principal element of which was the name JCM Industries."
For other decisions, see e.g. dw.com, mma.fr... (but not vw.com, transferred to Volkswagen, which trademark is famous).
