Catch up on these top five stories compiled by The Fly:

1. The Trump administration notified Huawei suppliers, including chipmaker Intel (INTC), that it is revoking certain licenses to sell to the Chinese company and intends to reject dozens of other applications to supply the telecommunications company, Reuters' Karen Freifeld and Alexandra Alper reported, citing people familiar with the matter. The action - likely the last against Huawei Technologies under Republican President Donald Trump - is the latest in a long-running effort to weaken the world's largest telecommunications equipment maker, which it says is a threat to U.S. national security and foreign policy interests, the authors noted.

2. Apple (AAPL) has begun early work on an iPhone with a foldable screen, a potential rival to similar devices from Samsung (SSNLF) and others, though it's planning only minor changes for this year's iPhone line, Bloomberg's Mark Gurman reported. The company has developed prototype foldable screens for internal testing, but hasn't solidified plans to actually launch a foldable iPhone, the author note. The development work hasn't expanded beyond a display, meaning Apple doesn't yet have full handset prototypes in its labs, according to a person familiar with the work.

3. Just over twenty years ago, Pat Gelsinger became Intel's first-ever chief technology officer and now he is back, with the CEO job he presumably wanted all along, Max Cherney wrote in this week's edition of Barron's. Gelsinger has his work cut out for him, the author added, noting that a series of manufacturing problems at Intel have allowed rivals AMD (AMD) and Nvidia (NVDA) to take share in key chip markets. Gelsinger's appointment is a step in the right direction, but a rebound will still take time, the publication contended.

4. State attorneys general are planning another lawsuit against Google (GOOGL), this one focused on the search and advertising giant's Play Store for Android phones, according to Reuters, citing two sources familiar with the matter. The lawsuit is expected to be filed in February or March, the sources said, and it would follow complaints about Google's management of its Play Store even though the company was originally seen as more open about its app store than Apple.

5. 3M (MMM) and Toll Brothers (TOL) saw positive mentions in this week's edition of Barron's, while GameStop (GME) was mentioned cautiously.
