HTC Corp, the world's No.4 smartphone maker, opened lower for a third session on Monday after news that it could face a sales ban in Germany, but soon turned positive to rise as much over 1 percent.
The company had fallen by the maximum daily limit in the past two sessions after a surprise cut its fourth-quarter guidance.
News on Friday that German patent firm IPCom plans to halt as quickly as possible the sale of all HTC smartphones in Germany.
At 0112 GMT, HTC was up 0.5 percent at T$492.
Investors had been worried that HTC may be running out of ideas in an increasingly competitive market, dominated by Apple's iPhones and Samsung Electronics' Galaxy line-up.
