Troubled former-rubber boot maker Nokia has decided to follow the business plan of others which are not making enough cash and turn into a patent troll.
Oddly its first target is one of its former chums, smartphone maker HTC.
According to Reuters, Nokia filed several lawsuits in Germany covering 45 hardware and software patents, ranging from power management to data encryption technologies against HTC, RIM and tablet-maker ViewSonic.
It has filed complaints in the US against HTC and ViewSonic, including a complaint to the U.S. International Trade Commission.
Last month Nokia warned that it was going to try and squeeze more cash from its patent portfolio.
However, the HTC suit is particularly nasty as the two companies fought for ages together against German patent firm IPCom.
HTC said it had been a licensee of Nokia on wireless essential patents since 2003 and it was waiting to receive a complaint.
The move follows a ruling in Germany which ruled that Microsoft had infringed Motorola Mobility's patents and would have to remove its Xbox 360 gaming consoles and Windows 7 operating system software from the German market.
Pretty soon it will be impossible to run computers in Germany as that nation has become the Texas of European patent law and seems to think that everything is stolen from someone.
Nokia is to be feared as a patent troll as it has one of the widest patent portfolios in the industry, along with Ericsson and Qualcomm.
The patents are for technology like synchronising information, including calendars, between the smartphone and mainframe computers, extending battery life and allowing mobile phones to be compatible with different systems.
