The table below compares Unlimited Rights, Government Purpose Rights, Limited Rights across 8 procurement-relevant dimensions, from what the government can do through statutory basis.
Side-by-side comparison
| Dimension | Unlimited Rights | Government Purpose Rights | Limited Rights |
|---|---|---|---|
| What the government can do | Use, modify, reproduce, release, disclose, perform, or display for any purpose, and authorize others (including commercially) to do the same. | Use and share within the government and with contractors performing government work; cannot use or authorize commercial use. | Use internally, including emergency repair/overhaul; cannot release or disclose outside government without the developer’s written permission (narrow statutory exceptions apply). |
| Can the government share it with another contractor? | Yes, without restriction. | Yes, but only for government purposes — the recipient contractor must also be barred from commercial use. | No, not without the data developer’s written permission. |
| Duration | Permanent — no expiration. | Converts to unlimited rights automatically after 5 years from the specified date, unless the contract negotiates a different period. | Permanent, unless the developer separately grants broader rights. |
| Funding source that triggers this tier | Data developed exclusively at government expense. | Data developed with mixed government and contractor funding. | Data developed exclusively at private expense. |
| Governing DFARS clause (technical data) | DFARS 252.227-7013 | DFARS 252.227-7013 | DFARS 252.227-7013 |

Common questions
Common questions about Unlimited Rights vs Government Purpose Rights vs Limited Rights
What is the difference between government purpose rights and unlimited rights?
+
Unlimited rights let the government (and anyone it authorizes) use the data for any purpose, including commercial use. Government purpose rights let the government use and share the data only within government and with contractors doing government work — commercial use by the government or any recipient is off limits until the rights convert to unlimited, ordinarily after five years.
How long do government purpose rights last before converting to unlimited rights?
+
The default period is five years from the date specified in the contract (typically delivery or acceptance of the item), after which the license converts to unlimited rights automatically. The parties can negotiate a different period at the time of contracting.
What is limited rights technical data?
+
Limited rights is the most protective DFARS tier: it applies to technical data developed exclusively at private expense and properly marked with the required legend. The government can use it internally, including for emergency repair or overhaul, but cannot release or disclose it outside government — not even to another contractor — without the data developer’s written permission.
Does DFARS government purpose rights apply to SBIR and STTR awards?
+
No. SBIR/STTR awards use a separate data-rights framework set by the SBA’s SBIR/STTR Policy Directive, with a 20-year protection period from date of award rather than the standard five-year government-purpose-rights clock, implemented at DoD via DFARS 252.227-7018 and at civilian agencies via FAR 52.227-20.
Does the civilian FAR have a government purpose rights tier?
+
No. The general civilian clause, FAR 52.227-14 (Rights in Data—General), defines only unlimited rights, limited rights, and restricted rights — there is no intermediate government-purpose-rights tier unless a specific agency adds supplemental contract language.
