What happened

Qualcomm, Inc.'s (NASDAQ:QCOM) stock price jumped 30.09% in 2016, according to data provided by S&P Global Market Intelligence, thanks to positive news for the company's patent licensing division, a midyear earnings beat, and Qualcomm's bid to buy NXP Semiconductors N.V. (NASDAQ:NXPI).

So what

Qualcomm's stock began ticking up in early 2016 after the company announced it was seeing improvements to its Qualcomm technology licensing (QTL) division. That was very welcome news to investors, as the company's most profitable division had been hit hard by smartphone makers, mainly in China, who refused to pay the 3G and 4G licensing fees that Qualcomm has come to rely on. 

The company said in February that it expected $8 billion from its QTL division in 2016, with that number hitting $10 billion by 2020. 

Then, in July, Qualcomm's stock price got another shot in the arm when the company easily beat analyst estimates and improved QTL revenue in the fiscal third quarter. Total revenue grew by 3.6% year over year to $6.04 billion -- beating the average analyst estimate by about $400 million -- and QTL revenue jumped 6% on a yearly basis.

The company also forecast optimistic earnings for the fiscal fourth quarter, further solidifying the idea that Qualcomm was leaving its most difficult days behind. 

The last major jump came toward the end of September on rumors (that later proved true) that Qualcomm was in talks to buy chipmaker NXP Semiconductors. The purchase of NXP could help Qualcomm transition beyond the slowing smartphone market and focus more of its attention on the growing Internet of Things and self-driving car markets. 

Now what 

Unfortunately, the investor optimism from 2016 hasn't exactly spilled into this year. The Federal Trade Commission (FTC) officially charged Qualcomm for antitrust patent licensing practices last month. That came around the same time that Apple launched two patent licensing lawsuits against the company as well.. The effect from the iPhone maker's and FTC's litigation has sent Qualcomm's stock tumbling more than 16% since the beginning of the year.

With the company just beginning the process of tackling these lawsuits -- and having just gotten out of similar patent licensing problems in 2016 -- it would appear that Qualcomm investors may be gearing up for a rocky 2017.
