What is your question please?
Yes, I understand.
The word "used" is the problem and is potentially an unfair contract term e.g. if you used third party IP during your employment, that does not mean that the Company would own it.
You may argue the same i.e. the mere fact that you used your IP during your employment does not mean that the Company acquired ownership of it. Under the law of commissioning, any IP created by you in the course of employment would be owned by the employer. In your case, you created the IP prior to your employment with the Company.
I am of the opinion that you have a good case to retain ownership of your IP.
I hope this helps. Please click on 5 stars if so.
