Three months ago, a rumor suggested it was Thompson's idea to threaten Facebook with a patent war. Thompson promised "a smaller, nimbler, more profitable" company, and one of the ways he chose to boost the company's business performance was to monetize its patent portfolio.
It all added up. Thompson made many changes at Yahoo since being appointed CEO. The Facebook lawsuit was undoubtedly his riskiest, although one could argue that if successful, it could also be the most worthwhile, financially speaking at least. The technology industry, including current and former Yahoo employees, was not pleased, but the papers had already been filed.
Now that Thompson is no longer at Yahoo, there is a glimmer of hope that his replacement will agree with the rest of industry that the move was a very poor miscalculation. Of course, the new CEO could decide that it would look worse if Yahoo pulled out now. After all, we're not just talking about one or two patents.
The disputed patent total is currently at 22. First Yahoo sued Facebook over 10 patents, then Facebook countersued Yahoo with 10 of its patents, and then Yahoo added two more patents to its attack.
Yahoo has already told Facebook it may infringe on 16 more patents, but I've personally been waiting for Facebook to hit back again first: either adding some of its own, some of the patents it bought from IBM, some AOL patents it's buying from Microsoft, or a combination.
I've previously said I hope Yahoo gives up its patent onslaught and focuses on building its business rather than patent trolling. With Thompson out, I hope the Web giant just drops the lawsuit altogether. That probably won't happen, but I think a settlement is significantly more likely now.
