There are patents, copyrights, trademarks etc. While a lot of innovative companies goes for patents of their innovation, so that they are not claimed by anyone else and only they have the right to its production. A common example of copyrights are movies, as you may know that plagiarism is not a legal thing, what makes it illegal is copyright which is done for all the movies, and also for books, songs etc. An example of trademark could be seen when companies get their logos trademarked, like that of Intel.
