Patent Market, Patent Watch, TPLF
Since late last year, RPX has flagged three batches of security agreements—each batch covering six different patent portfolios—all apparently involving the same third-party funder. Of the 18 funded patent portfolios, all but one has spawned new litigation campaigns, four having started last month. Meanwhile, public records provide hints as to the possible identity of the funder here—helpful hints, since the plaintiffs litigating in the Northern District of California or the District of New Jersey have apparently skirted, so far, respective disclosure requirements in those venues.

As RPX has elsewhere reported, DigitalDoors is one of 18 patent holders that appear to have made arrangements with the same funder, 17 of them having launched litigation to date.
