Input: Victor Schubert  who was a licensing director for BlackBerry   told Reuters in a brief LinkedIn message that  he  was no longer with the company.  He  did not say when  he  left or why.
Company representatives did not respond to requests for comment on  Schubert . Two switchboard operators at the Canadian company said his name was not in a global employee directory.
 Schubert  joined BlackBerry in March 2015  according to  his  LinkedIn profile  as the company was embarking on a major push to boost licensing revenue.
 Schubert  has created and executed patent-licensing programs for at least four companies  including BlackBerry  dating back to 1992  according to  his  LinkedIn profile. It lists portfolio mining  patent valuation and negotiating patent sales as areas of expertise.
 He  was due to represent BlackBerry at a Seattle-area patent conference next month to discuss how operating companies can make money off their intellectual property  according to an agenda posted on the conference website in August.  He  is no longer listed as a panelist.
BlackBerry disclosed it had secured royalty-bearing deals with Cisco Systems Inc and another company that it did not name soon after  Schubert  joined. It also filed patent infringement lawsuits during his tenure against Nokia and Avaya Inc [AVXX.UL] that are ongoing.
