The suit alleges trade mark infringement, cybersquatting and unfair competition. WebEx wants an injunction and damages.
According to WebEx, the domain name purchases – which include webexpc.com, mypcwebex.com and mywebexpcfree.com – were purchased in late January, on the same day that WebEx launched its new MyWebExPC service.
The service, which lets someone at work get files from their home PC, competes with Citrix's GoToMyPC products. WebEx suspects that Citrix is upset because WebEx offers for free what Citrix offers for $19 a month, according to a spokesperson for the company.
WebEx says that Citrix purchased the domains in an attempt to illegally divert customers who were attempting to find WebEx's new product web site.
The rival firm had earlier purchased other domain names containing WebEx's "AccessAnywhere" trade mark – a name previously contemplated as the title of the new WebEx services, according to WebEx.
Citrix has made no comment as yet.
