Samsung's CEO is keeping quiet ahead of critical rulings in German courts on the company's ongoing patent disputes with Apple.

As noted by the Korea Times, Samsung's approach to the lawsuits - in which rulings are expected on Friday - is far less bullish than it has been in recent months.

On 2 March a German court will rule on Samsung's allegations that Apple infringed on three of its patents, just weeks after German courts ruled in Cupertino's favour in another set of allegations brought by Samsung relating to smartphone and 3G technologies.

"I can’t talk about anything related to Apple. I will say for sure that Samsung has prepared a very sophisticated strategy to handle the litigation issues," Samsung's chief executive officer Choi Gee-sung said earlier today.

"Samsung is a big firm, and Apple is also. Samsung should respect Apple, while Apple also should respect Samsung."

Samsung is also said to be looking into the outcome of a case between Motorola Mobility in Apple in the country, which also went in Apple's favour this week.

"Our legal teams are in a difficult situation as they struggle to tackle new uncertainties. Still, the company wants Apple to pay in the range of several billions of dollars for using our wireless patents, so a lot of money is on the line," an unnamed senior Samsung executive said, according to the Korea Times.

"Our legal experts are closely studying the possible effect of Apple’s recent legal victory against Motorola and are ready to go the distance. Still, a cross-licensing deal remains as one possible scenario. The upcoming ruling in Germany is critical."

A ruling in Apple's favour could force Samsung to increase its efforts to sign some kind of peace treaty with Apple, a possibility that has been mooted before.

However, other elements within Samsung seem to be preparing for a long fight. Shin Jong-kyun, the head of the firm’s mobile devices division, said: "It could be foolish for us to compromise quickly with Apple and risk facing other legal fights with opportunistic rivals or even ‘patent trolls.’ This fight could become lengthy."
