Why It Matters
The Department of Defense (DOD) frequently cannot repair or maintain weapons systems it has purchased because contractors retain intellectual property (IP) rights over the technical data and software needed to do so, according to a new Congressional Research Service (CRS) report. DOD's own guidance acknowledges that "balancing the interests of the U.S. Government and industry in IP can be difficult."
A 2026 DOD Office of the Inspector General review of the F-35 Joint Strike Fighter program found that DOD did not "enforce a contract requirement for Lockheed Martin to identify and provide accurate data on Government property within its possession," warning that "inaccurate and incomplete inventory data could have a negative operational impact on the program and may lead to uninformed logistical and budgetary decisions."
The tension cuts in two directions: expanding data rights could reduce sustainment costs and strengthen military readiness, but more aggressive government IP acquisition could increase contracting costs and discourage private firms from working with the military.
The Big Picture
The Defense Federal Acquisition Regulation Supplement (DFARS) provides eight standard data rights licensing provisions, with the applicable tier depending on who funded development. DOD generally receives unlimited rights in data developed exclusively with government funds, limited or restricted rights for purely privately developed data, and government purpose rights (GPR) for mixed-funding arrangements, under which the government may use and reproduce data for governmental activities but may not disclose it commercially.
The Warrior Right to Repair Act of 2025 would require contractors to provide DOD fair and reasonable access to repair materials as a condition of contract award. A provision in the House-passed version of the fiscal year 2027 National Defense Authorization Act (NDAA), Section 861, would make GPR the default for technical data in future DOD contracts unless contractors justify more restrictive rights, and would require DOD to study recovering excess payments made due to unjustified data restrictions.
In February, the Department of Defense (DOD) issued Class Deviation 2026-O0036, which revised Defense Federal Acquisition Regulation Supplement Part 227 and replaced several traditional data rights clauses with new deviation clauses.
The Bottom Line
DOD's own guidance acknowledges that acquiring broader IP rights beyond what is necessary for maintenance and operations may lead to increased contracting costs or discourage private companies from working with the military. DOD's IP Cadre is already working to "modernize IP policies, culture, and best practices," but how those efforts intersect with congressional advocacy for broader data access rights remains an open question for the military's sustainment future.
