A patent gives the owner of some piece of intellectual property the right to be the exclusive maker or seller of that product or the exclusive owner of a patented process. Essentially, a patent precludes other from making the same product or using the same process that is covered under the patent.
A copyright is granted under United States law to those who author “original works of authorship”. A copyright occurs the moment something is created – it is automatic. However, a registered copyright is the formal registration of a specific piece of work with the copyright office.
Each year, the United States Patent and Trademark Office registers thousands of new corporate, collective, and personal logos. Additionally each year, the courts also review thousands of cases being litigated over instances of trademark infringement.
