The fear is understandable: you take government money, and the government takes your technology. For NASA SBIR and STTR, that fear is backwards. The program was built to help small companies commercialize, and the data-rights rules are the mechanism that makes it safe.
Under the Bayh-Dole framework, a small business that invents something under an SBIR award retains title to that invention. NASA receives a paid-up, government-purpose license, it can use the technology for federal purposes, but it does not own your patent and cannot take your company's commercial rights. You are free to patent, license, and sell to commercial and other customers.
The bigger protection is SBIR data rights. Technical data you generate under the award, your designs, test results, know-how, is marked with an SBIR legend and protected for a period of roughly 20 years from award. During that window the government cannot release that data outside the government or hand it to a competitor. This is what stops a prime contractor from getting your hard-won engineering data for free.
Plain version: You own the invention. NASA gets a license to use it, not to sell it or give it away. And your technical data stays protected for about 20 years, which is exactly what lets a Phase III contract be handed straight to you.

SBIR costs you neither, no equity, no board seat, no cost share, and you walk away owning the invention and holding the data rights. It is close to the only funding on earth that hands you money and lets you keep everything.
Data rights also power the best-kept secret in the program: Phase III. Because your Phase I/II work is protected and traceable to you, an agency or prime that wants the matured technology can award you a Phase III contract sole-source, no open competition, no dollar limit, no cost share. Your data rights are precisely what make that direct award defensible. In effect, the IP protection converts into a procurement advantage.
The headline for a space-hardware founder is simple: NASA SBIR does not take your equity and does not take your invention. Handled correctly, it funds your technology, protects your data, and hands you a direct path to a real contract. Read the official terms at nasa.gov/sbir_sttr before you sign.
