U.S. Patents

U.S. patents are for protecting any innovative products/inventions that you come up with

U.S. patents are for protecting products (inventions) for up to 15 or 20 years.

If you ever come up with a new product that looks unique in some way, that works in some special way, and/or solves some problem in a special way, then you might consider pursuing obtaining a U.S. patent, either utility and/or design to protect that new product. 

Note, software (e.g., mobile apps) may or may not be patentable.
