Last week Alphabet (GOOGL) - Get Report  was on the winning side of a large legal battle with Oracle (ORCL) - Get Report that could have cost the search giant almost $10 billion. Now Oracle is back in court Tuesday to fight another tech company, this time the former Hewlett-Packard.

This time it's Oracle that's playing defense. HP is seeking $3 billion in damages from its partner-turned-competitor. The issue is Oracle's acquisition of Sun Microsystems in 2010. Partly because of the purchase, HPE alleges Oracle helped to drive the drop in sales of the old Hewlett-Packard's Itanium products.

Oracle disputed the allegation, saying Itanium sales fell from $3.1 billion in 2011 to $876 million in 2015 for other reasons.

Another part of the battle is Mark Hurd, now the co-CEO of Oracle. He previously served as the CEO of the old Hewlett-Packard before he was asked by the board to resign. Oracle didn't waste any time snapping up Hurd, making him the co-president of the company.

Hewlett said Hurd possessed insider knowledge giving Oracle an edge. Oracle said it will stop creating certain software for Hewlett's Itanium systems. Hewlett filed a lawsuit in response and, in 2012, the legal system agreed: Oracle needed to keep producing the systems.

The new trial will look at whether any company has violated its previous agreements and if either is entitled to damages. Since the original lawsuit, Hewlett-Packard split into Hewlett Packard Enterprises (HPE) - Get Report and HP Inc. (HPQ) - Get Report .

Oracle closed at $40.20 Tuesday, up 0.3%.

If we've learned anything in the auto industry over the past few years, it's that the big players aren't the only ones running the show now. Tech players including Alphabet and Tesla (TSLA) - Get Report are emerging as legitimate players in the business.

Another, lesser-known company is now popping up on the map: Zoox. The autonomous-driving startup is looking to raise up to $252 million and could be valued at more than $1 billion.

Not much is known about the company, but it was only one of two startups to have a license for operating autonomous vehicles in California. Now that General Motors  (GM) - Get Report has acquired the other, Cruise Automation, it's the only startup with one.

Although tech companies and automakers are racing toward the finish line -- or starting line? -- for introducing autonomous driving to the masses, there is skepticism about the technology, especially from consumers.

But over time, the companies are banking on a more accepting environment, both from customers and regulators.

Scratch Turkey off the list of countries where PayPal (PYPL) - Get Report  operates. Beginning June 6, customers will no longer be able to access the service unless it is to withdraw money to deposit into their bank.

Of course, PayPal didn't make the move simply because it doesn't like Turkey. The company says a new policy from the country's financial regulator, BDDK, is preventing the company from obtaining the proper license. The policy required PayPal to open an IT center in Turkey, something PayPal doesn't "consider doable," according to CNET.

Either comply, build the IT infrastructure and operate or get out. For now at least, PayPal is leaving.

PayPal closed at $37.79 Tuesday, down 0.8%.
