My team at work invested about 18 months researching and building a methodology for evaluation of patents and patent portfolios. The table below shows the scores of the portfolio being auctioned (best guess using assignee/inventor searches, as the press release did not mention the patent numbers)
4 of the 5 US patents are 98th percentile or higher among comparable patents with exceptionally high scores.
It remains to be seen how much value does this portfolio fetch. Guess we will know in a few weeks time.
