Employment IP Audit

One-time review of your employment agreement with your MSP employer before FlashFusion signs any client contracts. Do not skip.
The risk: Most employment agreements contain an IP assignment clause that says anything you create during employment that's related to the employer's business belongs to them. If that clause is broad, it could cloud FlashFusion's IP, especially any tools built at work or skills libraries created on company time. You need to know exactly what it says before a client pays you.

What to Pull Out of Your Employment Agreement

What to Tell Your Startup Attorney

BRIEF FOR ATTORNEY, EMPLOYMENT IP REVIEW I am a full-time employee at a managed IT services firm (not named for privacy reasons). I am forming FlashFusion LLC, a B2B AI enablement consultancy. I have no non-compete clause to my knowledge, but I need the exact language verified. Key questions for review: 1. Does my employment agreement contain an IP assignment clause, and if so, what does it cover? 2. Does the clause apply to work done entirely on my own time, using my own equipment, unrelated to my employer's core business? 3. My employer is an MSP (managed IT / service desk). My business is B2B AI enablement consulting. Is there a colorable argument that these are related enough to create an IP claim issue? 4. Do I have any disclosure obligation to my employer about FlashFusion before I begin taking paying clients? 5. Are there any other provisions, non-solicitation, confidentiality, moonlighting, that I need to structure around? 6. Does the Illinois Employee Patent Act (765 ILCS 1060/2) protect any of my pre-formation work from employer claims? Please advise before I execute the IP Assignment Agreement or sign any client contracts under FlashFusion LLC.
