BlackBerry sues Twitter for allegedly infringing six messaging patents; BlackBerry sued Facebook and Snap in 2018, also alleging messaging patent infringement
Context & Ripple Effects
The Twitter suit is the third filing in BlackBerry's messaging-patent campaign: it went after Facebook in March 2018 seeking damages and injunctive relief (its suit against Facebook), added Snap a month later on six patents, two shared with the Facebook case (the Snap complaint), and drew a counterattack when Facebook accused BlackBerry of infringing voice-messaging patents (Facebook's countersuit).
The campaign matters because BlackBerry's handset business is gone and litigation is one of the few levers left on its legacy IP portfolio — a lever that cut both ways when it was ordered to pay Nokia $137M in a related contract dispute while still pursuing its own infringement claims (the Nokia ruling).
First-order effects
- Twitter joins Facebook and Snap as a defendant facing BlackBerry's six messaging patents, adding legal costs and, if BlackBerry repeats its Facebook demand, potential exposure to an injunction against core messaging features.
- BlackBerry converts patents that once protected its own phones into direct claims against three of the largest US social platforms, testing whether the portfolio can generate licensing revenue without hardware.
Second-order effects
- The pending Facebook case becomes the bellwether: a win or settlement there strengthens BlackBerry's hand against Twitter and Snap, while Facebook's countersuit raises BlackBerry's own infringement risk on voice-messaging technology.
- Any platform whose messaging features resemble the patented notification and delivery techniques — effectively every major social app — faces pressure to license proactively rather than wait for a complaint.
Third-order effects
- If the pattern holds, BlackBerry completes its shift from device maker to patent-licensing operation, and large platforms begin budgeting royalties on foundational messaging UI and delivery patents as a standing cost of shipping chat features.
The trend: BlackBerry is systematically monetizing its messaging patent estate through serial lawsuits against social platforms, with each verdict shaping the price the next defendant pays.
