What do you expect? Facebook will see it, say "That's cool!" and then offer you a 20M buyout? Hell no, they'll just take a week, build it in-house, and move on to the next feature.
Moreover, Lifeblob has shot in their foot with this. Lifeblob's content is hosted in US (Softlayer as host). If Facebook gets a patent on the recommendation engine they and Lifeblob is using, they can issue a takedown notice to Lifeblob from american servers.
Actions like Lifeblob's only end up destroying the web ecosystem.
Even if FB did independently invent the feature, LB's US-hosted and US-available feature might count as "prior art" that knocked out FB's ability to get a patent.
Of course, much depends on just what FB would try to claim.
But you may be right. LB being hosted in US might well be qualified as 'operating in US', which might prevent FB getting patent in US.
In any case, if LB was so paranoid about someone stealing their 'photo recommendation engine', they must have at the very least filed patent pending applications in India and US.
LB's outburst suggest they are thinking of this as an infringement of some sort, but these things won't work in web startups. How many countries will anyone run around getting patents to make sure nobody else does it? Maybe, in future we have better governing stuff for the web,
Now if someone had taken their name, changed a letter, then their logo and made it 3D, and them built a big brand around it, then I'd say go sue their asses off. But this? Seriously?
It's not just fb either. The idea of finding and presenting users with associated content they would find interesting is a staple feature of most social sites
But back to the point of copying it's feature of associating related photos. Everyone copies from everyone else, or putting it politely as "getting inspiration from". This is the reality, no point whining about it. Take it as a compliment and move on.
