Qualcomm, Broadcom, and the valuation of patents.

You may remember that Broadcom claims Qualcomm is infringing some of its patents, and thus got a ban on Qualcomm patents based cell phone chips.

On the other side, Qualcomm kept secret it was holding video compression patents during the H.264 standardization phase, and then tried to blackmail make money from it. However Qualcomm was found guilty of “patent ambush”.

Qualcomm apologized (but will appeal).

The lesson ? Qualcomm gonna have a hard time enforcing its patent, which is perfectly good under US laws until proven otherwise. This once again calls into question the valuation of a patent…
