1. I am in the business of invention. I invent many things. I cannot possibly disclose all of them. Hence, ANYTHING I have done in the past is excluded and ANYTHING I will do after I leave your employ is excluded without having to be disclosed. This is true even if the thing invented can be construed to be directly or indirectly connected to your business. The only exception to this will be those things directly and explicitly connected to your IP disclosed to me during my employ for a period not to exceed two years after my departure for un-registered un-patented IP. Normal patent and copyright laws apply - BOTH ways.
2. What I do 0n your time with your equipment on projects specifically assigned to me is yours.
3. What I do on my time with my equipment on my self assigned projects distinct from yours is mine.
4. Since my business is invention, if the invention was concieved on your premises but is not DIRECTLY connected to your business, your disclosed IP, and your assigned project, the invention is mine. This will be true even if the invention is used to indirectly support project. In that case, a non-exclusive license to use will be granted by me to you but I still own the resultant IP.
Almost without exception, the terms were accepted. Where there was substantial disagreement, I looked for another job/contract.
