This is how to calculate the value of a patent portfolio
I start with cost plus model:
Patent file number
•Patent certificate number
Country
•Patent title
•Abstract
•Cost incurred( including break down)
•Cost needed to •maintain(including break down, present value)
•Year granted (20 years patent life)
•Life remaining
•First inventer
•Other inventer
•Fields of main use
•Citing number
•Citation entities
•Contribution margin per wafer
•Cost plus with 25/50/200%
Bulk rate vs. single patent rate.
I start at 250k USD with patent that has citations from competitors/big fabs/big design houses
Then I start to play
