Unseasonably hot news from Finland today as it emerges that mobile handset giant Nokia is busy in the Federal District Court in Delaware, US, with plans to sue Apple over patent infringement.
Nokia is taking Apple to task because the company "infringes Nokia patents for GSM, UMTS and wireless LAN (WLAN) standards" - in other words, critical elements of Nokia's technology for handling wireless data, speech coding, security and encryption.
At a corporate level this could be quite a scrap, given the enormity of what is at stake (the action relates to every iPhone shipped since 2007!) and the size of the companies involved.
But spare a thought for Dopplr, what some believe to be is the travel social network of the moment, which has a popular and rather cool-looking iPhone app currently resting at around 40th place in the most popular travel apps on the iTunes App Store.
The UK-based firm could find itself in the middle of this most messy of bunfights given that it is now owned by Nokia.
And this often strikes at the heard of the psyche of start-up - does it want to be involved or forced to tow the party line when the parent company falls out in such dramatic fashion with another company?
It may not have any choice, of course. But Dopplr's reach and targets for increasing engagement with users probably rely on providing innovative tools such as the iPhone app.
We await news from Lapland...
NB: Nokia, Dopplr, Apple were all unavailable for comment.
