BlackBerry is suing Facebook and its subsidiaries, Instagram and WhatsApp, alleging the social network has infringed on some of its patents including security features, mobile notifications, and combining gaming with messaging.

Why it matters: BlackBerry no longer makes phones, but it's still looking to profit from patent licenses and software. This is not the first time Facebook has been sued by a fellow digital giant; in 2012, Yahoo sued Facebook, alleging it infringed on some of its advertising patents. BlackBerry, meanwhile, has also gone after Nokia and others.

Facebook's take:

“Blackberry’s suit sadly reflects the current state of its messaging business. Having abandoned its efforts to innovate, Blackberry is now looking to tax the innovation of others. We intend to fight.”
— Paul Grewal, FB deputy general counsel

BlackBerry's take

“We have a lot of respect for Facebook and the value they’ve placed on messaging capabilities, some of which were invented by BlackBerry. As a cybersecurity and embedded software leader, BlackBerry’s view is that Facebook, Instagram, and WhatsApp could make great partners in our drive toward a securely connected future, and we continue to hold this door open to them. However, we have a strong claim that Facebook has infringed on our intellectual property, and after several years of dialogue, we also have an obligation to our shareholders to pursue appropriate legal remedies.”

Changing the inflation conversation

Inflation looks like it’ll run hot for longer than plenty of smart people thought it would. The conversation over just how much more Americans will have to pay for their stuff has taken on a new intensity, as supply problems show few signs of fading.

Why it matters: The rate of price growth has remained consistently strong in recent months — a time that some thought would bring cooling prices after an initial reopening spike. What goes on with prices will influence the decisions made by Congress, the Biden Administration, and the Federal Reserve.

The biggest headline from Biden's town hall

What matters from President Biden's town hall with CNN's Anderson Cooper at Baltimore Center Stage on Thursday, via Axios night owl Hans Nichols:

The biggest headline: Biden is jettisoning the corporate tax increases that White House officials have insisted, for the past 10 months, are wildly popular across the country. He admitted he doesn't have the votes.

Trump, your 2024 GOP nominee

Former President Trump is telling most anyone who'll listen he will run again in 2024 — and poll after poll shows the vast majority of Republicans would gladly cheer him on and vote for him. 

Why it matters: Trump is the heart, soul and undisputed leader of the Republican Party and will easily win the nomination if he wants it, the polls make unmistakably clear.
