Patents protect inventions. An invention may be a new product that has an improved use, or a design.  Patents typically last 20 years give you the right to stop others from making, using, or selling your patented idea without your permission. Please see the "Patents" section under "Services" for details.

Trademarks protect business names, product names, services names, logos, and sometimes sounds, videos or even smell that tell consumers the source of the goods or services.  These rights can last indefinitely as long as you keep using them. Please see the "Trademarks" section under "Services" for details.

Copyrights protect original works of authorship.  This includes a wide variety of creative areas that end up in a "fixed medium" such as  books, music, movies, art work, and more.  Copyrights generally last 70 years after the death of the author. Please see the "Copyrights" section under "Services" for details.
