March-In Rights: NASA Life-Support Patent Simulator

Space life-support hardware — CO₂ scrubbers, water recovery loops, oxygen generators — is overwhelmingly developed under NASA funding, which means its patents almost always fall under the Bayh-Dole Act: the contractor keeps title, but the government keeps a standing license and the power to march in if commercialization stalls. This simulator runs that clock live — a logistic model of practical-application progress driven by a tunable commercialization-effort slider, racing against an accruing march-in risk score once a tunable "reasonable time" window elapses — and renders the outcome as a rotating patented module whose exclusivity shield erodes over the 20-year statutory term and collapses to the government-license floor, with rival licensee satellites appearing, the moment march-in is invoked.
