Foundational patents

In the technological and manufacturing atmosphere of Worcester, patents were considered essential, not only to protect original work but as documentation of first discovery. He began to see the importance of his ideas as intellectual property, and thus began to secure those ideas before someone else did—and he would have to pay to use them. In May 1913, he wrote descriptions concerning his first rocket patent applications. His father brought them to a patent lawyer in Worcester who helped him to refine his ideas for consideration. Goddard's first patent application was submitted in October 1913.

In 1914, his first two landmark patents were accepted and registered. The first, U.S. patent 1,102,653, described a multi-stage rocket fueled with a solid "explosive material." The second, U.S. patent 1,103,503, described a rocket fueled with a solid fuel (explosive material) or with liquid propellants (gasoline and liquid nitrous oxide). The two patents would eventually become important milestones in the history of rocketry. Overall, 214 patents were published, some posthumously by his wife.
