What essential IP ownership clauses should every independent contractor double-check before signing?
I received a consulting agreement from a US client where Section 4 mentions "Work for Hire and Perpetual Global Assignment of all Pre-existing Intellectual Property used during performance of services."
Is this clause standard, or does this mean if I use my own personal open-source utility libraries, the client could claim ownership over my pre-existing code?

As an intellectual property and corporate IT attorney:
**Do NOT sign that agreement as currently worded.** Section 4’s phrasing—specifically *"Perpetual Global Assignment of all Pre-existing Intellectual Property used during performance of services"*—is a classic **overreaching IP trap** intended to sweep up contractor background IP.
### Required Contractual Fix:
You must request an immediate carve-out amendment inserting a **"Background IP Reservation and License Clause"**.
The exact wording your agreement needs should state:
> *"Contractor explicitly reserves all right, title, and interest in and to all Pre-existing Background IP, tools, frameworks, and open-source utilities developed prior to or independently of this Agreement. To the extent any Pre-existing Background IP is embedded in the final deliverables, Contractor grants Client a non-exclusive, perpetual, royalty-free license to use such Background IP solely as integrated within the specific deliverables, without transferring ownership."*
Never allow a client to take ownership over your underlying background toolkit.
