Why is Microsoft insisting on a patent license for Caller ID?
They are
offering a royalty free license, so it obviously isn't
immediate financial
concerns that is driving their desire to require a patent
license. Are they
just trying to protect themselves from a third-party
patenting a portion of
Caller ID?
I believe so. It is the main reason for most of the applications
I put in.
If you are in a favorable market position such as Microsoft or
VeriSign enjoie s in our markets there is not a lot of value
in chasing patent royalties.
I did a check of the patent applications I made in this area, I
don't think any are necessary for SPF, CallerID or MARID.
