Are there any good patent services that work with government research labs?
Yes, but look specifically for firms experienced with the Bayh-Dole Act, which governs patents on inventions made with federal funding. Bayh-Dole lets federal labs, universities and small businesses retain ownership of inventions developed under federal grants or contracts, including SBIR/STTR awards. rather than assigning them to the government, in exchange for compliance obligations like iEdison invention reporting and the government's retained "march-in" rights, which in more than 40 years have never actually been exercised.
A firm that regularly handles SBIR/STTR-funded clients will know the reporting deadlines and the government-use-rights language that needs to appear in the specification. Gaps here don't usually block a grant, but they can create compliance problems later if the invention gets commercialized.
