If you own in money CALL option, You could exercise any day.
Why would you exercise anyway until last minutes since you would pay same price on last day?. It is already your stock why hurry. You probably want to exercise early if they have cut off date for dividend, etc.. That is not the case with IDCC.
Most option buyer probably close out their position and take their gain/loss rather than exercise. Some may have bought CALL 30 much higher than $2 (those when IDCC was $30-$35). They naturally want to close out the position to take loss rather than exercise in-money option.
One who bought 30 CALL option when IDCC was around $20 would get huge gain. They may close position too to take short term gain since they may not have money to exercise all call.
If I own call option in money today with no time value left, I normally close all position today. Get cash then buy stock right way whatever money coming in if I still like the stock.
I guess more than 50% of in money call would close position on the last day.
