SBIR, STTR & University Tech Transfer Government Contracting Guide (2026)

Step 1: Choose Between SBIR and STTR (Workshare, PI Employment & University Teaming Rules) (15 U.S.C. 638 & SBA SBIR/STTR Policy Directive § 6(a))

Understand the statutory differences between SBIR and STTR workshare percentages, Principal Investigator (PI) primary employment rules, and when a university research partnership is mandatory versus optional.

Although SBIR and STTR share the same three-phase acquisition lifecycle and protect small business data rights identically, they govern university participation and Principal Investigator (PI) employment very differently under the SBA SBIR/STTR Policy Directive.

Under SBIR, the Small Business Concern (SBC) is the solo focus: the Principal Investigator must be >50% employed by the small business at the time of award and throughout contract performance, and the small business must perform at least two-thirds (67%) of the research/analytical effort in Phase I and at least 50% in Phase II. A university can still participate on an SBIR as a subcontractor, but its share is capped at 33% in Phase I and 50% in Phase II.

Under STTR, a formal cooperative R&D partnership between a small business and a U.S. Research Institution (RI)—such as an R1/R2 university, non-profit research foundation, or Federally Funded Research and Development Center (FFRDC)—is mandatory. The small business must perform at least 40% of the work, and the partnering university or research institution must perform at least 30% of the work (leaving the remaining 30% flexible between either party or third-party subcontractors). Crucially, in many agencies (including DoD, NIH, and DOE), an STTR Principal Investigator may remain primarily employed as a full-time university faculty member while leading the STTR project, making STTR the premier bridge for university spinouts and lab commercialization.

Step 1 Checklist

• Verify small business eligibility under 13 CFR 121.702: U.S.-owned (>50% owned by U.S. citizens or permanent residents) and under 500 employees including affiliates.
• Determine Principal Investigator (PI) availability: if the PI cannot take >50% leave from their university faculty appointment during Phase I, select STTR (where permitted by the agency solicitation) or designate a postdoctoral/company researcher as the SBC PI.
• Calculate budget splits using total contract dollars (direct + indirect + fee): verify >=67% SBC (SBIR Phase I), >=50% SBC (SBIR Phase II), or >=40% SBC + >=30% Research Institution (STTR Phases I & II).
• Check NAICS codes 541715 (R&D in Physical, Engineering, and Life Sciences) and 541714 (R&D in Biotechnology), which govern over 85% of federal SBIR/STTR solicitations.

Step 2: Target the Right Agency Vehicle: Acquisition Contracts (DoD, NASA) vs. R&D Grants (NIH, NSF, DOE) (FAR Part 35 (R&D Contracting) & DFARS 252.227-7018)

Distinguish between procuring agencies that award FAR-based acquisition contracts for agency consumption versus grant-making agencies that fund commercial market technologies.

Not all SBIR/STTR awards operate under the same legal rules. Five federal agencies—most notably the Department of Defense (DoD via DSIP), NASA, DHS, and DOT—award FAR-governed Procurement Contracts. When the Air Force (AFWERX), Navy, Army, or DARPA issues an SBIR/STTR contract, the government is acting as your customer: they want to buy, integrate, and field your technology inside a defense program of record (via PSC codes in the AC11–AC33 National Defense R&D series or AD series).

Conversely, agencies like the National Science Foundation (NSF), National Institutes of Health (NIH), Department of Energy (DOE), and USDA award Financial Assistance Grants. NSF and NIH will never be the end buyer of your medical device or software platform; instead, peer-review panels score your scientific innovation and commercial venture viability in the private or healthcare market.

For university technology transfer offices (OTCs/OSPs) and commercial contractors alike, DoD and NASA SBIR/STTR contracts offer the fastest path to recurring federal revenue because successful Phase II prototypes can transition directly into multi-million-dollar Phase III Indefinite-Delivery/Indefinite-Quantity (IDIQ) production contracts with Program Executive Offices (PEOs).

Step 2 Checklist

• Register on all 3 mandatory federal R&D portals: SAM.gov (UEI & CAGE Code), SBA Company Registry (SBIR.gov to generate your SBC Control ID), and agency submission portals (DoD DSIP, NIH eRA Commons, NSF Research.gov, or Grants.gov).
• During the DoD Pre-Release window (typically 2–4 weeks before BAA open), email or schedule a 15-minute call with the Technical Point of Contact (TPOC) listed on the topic to validate your technical approach.
• For Open Topic solicitations (such as AFWERX / SpaceWERX), identify a Defense End-User and Customer Memorandum (MOU) partner inside an active operational unit before Phase II.

Step 3: Structure University Sponsored Research, Subawards & Bayh-Dole IP Allocation Agreements (35 U.S.C. 200–212 (Bayh-Dole Act) & 37 CFR Part 401)

Coordinate early with the university’s Office of Sponsored Programs (OSP) and Office of Technology Commercialization (OTC) to lock in Facilities & Administrative (F&A) indirect rates, subaward budgets, and STTR Model IP Agreements.

When teaming with a university on an STTR or SBIR proposal, thesmall business is always the Prime Applicant/Offeror that submits the proposal to the federal government, and the university participates via a Subaward / Sponsored Research Agreement. However, universities cannot legally commit faculty time, lab facilities, or cost rates without formal sign-off from their Office of Sponsored Programs (OSP). Most R1/R2 university OSPs enforce a strict 5-to-10-business-day internal routing deadline prior to the federal submission date.

Under the Bayh-Dole Act (35 U.S.C. 200–212 and 37 CFR Part 401), both small businesses and universities retain title to "Subject Inventions" conceived or first actually reduced to practice using federal funds, subject to a non-exclusive government-purpose license. When an invention is jointly developed or when the small business is commercializing background university patents, the SBA STTR Policy Directive requires the Small Business and the Research Institution to execute a formal Allocation of Rights (IP) Agreement prior to receiving an STTR award.

Additionally, verify how the university’s Federally Negotiated Indirect Cost Rate Agreement (NICRA / F&A rate, often 50%–65% Modified Total Direct Costs) counts toward the 30%–60% university budget allocation. Because SBA workshare percentages are calculated against total contract funds (including indirects and fee), a high university F&A rate can accidentally push the university’s budget share above 50% on an SBIR or above 60% on an STTR if not modeled early.

Step 3 Checklist

• Contact the university Principle Investigator’s departmental grant administrator and Office of Sponsored Programs (OSP) at least 3 weeks before the BAA deadline.
• Obtain the signed Subrecipient Commitment Form, University Statement of Work (SOW), Budget & Budget Justification (with current DHHS/ONR negotiated F&A rate agreement), and Biosketches.
• Execute an STTR Allocation of Rights Agreement (using the SBA Model IP Agreement template) with the university’s Office of Technology Commercialization (OTC / Tech Transfer Office) defining background IP licenses and commercial royalty terms.
• Disclose any Conflict of Interest (COI): if a university faculty member holds equity in the small business spinout, ensure a formal University COI Management Plan is approved.

Step 4: Protect 20-Year SBIR/STTR Data Rights & Transition to Uncapped Phase III Sole-Source Contracts (FAR 52.227-20 · DFARS 252.227-7018 · 15 U.S.C. 638(r)(4))

Leverage the 20-year statutory SBIR/STTR Data Rights protection shield to compel federal agencies and Prime Contractors to award non-competitive Phase III production contracts.

The single most valuable asset created by a Phase I or Phase II SBIR/STTR award is not the initial R&D check—it is your statutory SBIR/STTR Data Rights and Phase III sole-source authority under 15 U.S.C. 638(r)(4). Under the SBA Policy Directive and DFARS 252.227-7018, the federal government cannot disclose your technical data or computer software developed under an SBIR/STTR contract outside the government for 20 years from the date of award.

Because no competitor can legally access your SBIR technical data package, and because Congress explicitly mandated that Phase III awards be given the "greatest practicable extent" of sole-source preference, any federal agency (even an agency that did not fund your original Phase I/II!) can award you a non-competitive, sole-source Phase III contract at any dollar value ($5M, $25M, or $100M+) using non-SBIR operational, procurement (O&M / Procurement), or working-capital funds.

Even better: Phase III sole-source contracts are exempt from standard FAR Part 6 J&A competition hurdles (the prior Phase I/II competition legally satisfies the Competition in Contracting Act requirement), and a company remains eligible to receive Phase III sole-source awards even if it later outgrows the 500-employee SBA size standard or is acquired.

Step 4 Checklist

• Place the exact mandatory FAR 52.227-20 or DFARS 252.227-7018 SBIR/STTR Data Rights legend on every technical deliverable, software repository, and slide deck submitted to the government.
• Maintain a clean traceability matrix showing how your current product or service derives from, extends, or logically concludes work performed under your Phase I/II Topic Number and Contract Number.
• Partner with Large Defense Primes (Lockheed Martin, RTX, Northrop Grumman, Booz Allen, Leidos): Primes actively seek SBIR Phase II holders because integrating your SBIR technology into their program of record satisfies subcontracting goals and unlocks rapid Phase III contracting.
