Registration gives you a presumption of ownership (See CASTAT. § 14241). This means the starting point in any litigation will be that you own the mark and the other party has the burden of proving otherwise. Such presumption gives you the right to bring a lawsuit to:

• get an immediate injunction to stop the other party from using, reproducing, or enabling another to use or reproduce your mark; and

• collect profits from the other party of up to three times those actually derived from use or reproduction of your mark; and

• collect damages from the other party of up to three times those actually incurred by you; and

• get a seizure order for counterfeit goods; and

• force the disposal of or destruction of any and all infringing materials.

Yes, but you won't have any presumptive rights. This means you will be forced to plead ownership with substantial evidence under what's called the "Common Law" See CASTAT. §14210). This means you won't have a statutory cause of action, but rather will have to file a lawsuit under Unfair Competition and/or Deceptive Trade doctrines. As such, you will have to plead and prove that the infringer is in competition with you or that confusion as to the source of the goods or services exists. In contrast, if you are registered, you can get an injunction by merely showing a likelihood of injury to your business reputation or that continued infringement will dilute or diminish the strength of your mark (See CASTAT. §14330). In short, registration ensures more predictable outcomes and makes protecting your mark much easier and less expensive.
