<<17 years from date of issue for patents in early 90's. 20 years from date of filing for late 90's patents. And I believe the soft handoff patents was issued in Nov 93. (the power control patent in Oct 91).>>
Thanks Clarksterh, now I see the light. In fact Carranza's mail form 2001 made it even more clear:
<<The spread spectrum patent, 4,901,307, was issued on Feb. 13, 1990. Application date was October 17, 1986.
The power control patent, 5,056,109, was issued on October 8, 1991. Application date was Nov. 7, 1989.
The soft handoff patent, 5,101,501, was issued on March 31, 1992. Application date was Nov. 7, 1989.
The wave form patent, 5,103,459, was issued on April 7, 1992. Application date was June 25, 1990.
The rake receiver patent, 5,109,390, was issued on April 28, 1992. Application date was Nov. 7, 1989.
I don't know if the 17 year rule from date of issuance applies or if the 20 year from date of application rule controls. If the 17 year rule is applicable, the expiration date for the last of Q's basic patents is April 28, 2009. If the 20 year rule controls, the latest expiration date is June 25 , 2010.>>
So now I will make another ridiculous comment, feel free to shoot it down! Nokia signed the deal with Qualcomm in 1992, and ALL the patents that were in Qualcomm's portfolio at that time, will be expired by 2009-2010 time frame. In 2001 that may have looked like a distant future, but there now is only 3-4 years left and the clock is ticking... And Qualcomm is trading at a P/E rate of around 20, while some believe that the P/E could/should be closer to 40.
BTW, I don't own/short Qualcomm or Nokia shares. I'm just trying to educate myself about these issues and e.g. this Message 16815077 Carranza's mail from 2001 was most helpful, thanks for it! |
