A copyright owner who registers within three months of publication, or before an infringement begins, can recover statutory damages and attorney's fees; one who registers later is limited to actual damages and the infringer's profits, which for most online copying is nothing worth suing over. The fee is small. The difference is the whole case.
Trademark rights arise from use, but a federal registration gives nationwide priority from its filing date and, after five years of continuous use following registration, can become incontestable. Both rights rest on paper that must exist before the dispute does: a clearance search run before the name is on the door, a signed assignment from every contractor on the creative, and a substantiation file for every claim a campaign makes, because the FTC asks for the evidence after the ad runs.
We treat the three regimes as one practice because a launch, a rebrand or a campaign raises all of them at once. We clear and register marks, document and license copyright, and review advertising against the FTC's substantiation and endorsement rules, coordinating locally admitted counsel where a foreign filing requires it.
