The site is run in conjunction with the Electronic Frontier Foundation and the IP Law Clinics of various law schools. The information is not a substitute for a hiring an actual lawyer, but if you have questions, or have received a "Cease and Desist" letter or the like, it is a good place to start to help you understand the issues involved.
If you have received a letter, you can submit it for help. You can also review other letters, faq's, and IP 'weather reports', among other things.
The main relevance to this particular area of the forum is in the realm of copyright, trademark, DMCA, linking, free speech and defamation, though cybersquatting and other areas may be of general interest.
Please keep in mind that the website is only meant to be a guide to helping people understand the issues involved, and the general legal landscape around intellectual property issues. It is not a substitute for competent legal counsel, but can assist you in making informed choices.
