How would you be able to calculate lost profits due to patent infringement? I have a project due coming up, and I need assistance on how to even begin. We need to use an 8% discount rate to present the data as of 1/1/17.

Update: This was a general question. The only information given was "Requirement: I would like you to calculate GoPro's Lost Profits in 2016 and 2017 as a result of Polaroid's infringement of GoPro's patents. I would like the analysis presented as of January 1, 2017. To present 2017 data as of 1/1/17, please use an 8% discount rate." and links to GoPro's 10k forms.
