Could co-inventors receive different personal inventor shares for the same invention?
Yes, sometimes they would. In the past the Universitys position that it could change invention royalty distribution formulas as a matter of policy allowed the University to select an effective date (the date of the policy change) at which time all inventors on a newly disclosed invention would be treated the same under the Current (1997) policy. Introducing the employment date of the inventor as one determining factor as to which royalty distribution formula would apply changes this. Different inventors on the same invention could have different employment dates and thereby could have different applicable royalty distribution formulas. Please note, though, that unless you and your co-inventors have made a separate disposition of the inventors’ allocation, your choice of policy will not affect funds available to co-inventors on any past, present, or future inventions.
