New York, January 6, 2026, 14:58 EST — Regular session
- Shares down about 7% in afternoon trade, underperforming the tech-heavy Nasdaq-100 tracker
- A new Form 144 filing showed an InterDigital officer proposed selling 1,000 shares
- Investors are watching the Amazon patent dispute, the Jan. 14 dividend record date and early-February earnings timing
InterDigital, Inc (IDCC) shares fell about 7.3% to $311.23 in afternoon trading on Tuesday after touching $309.30, giving back a chunk of Monday’s close at $335.84. The stock earlier traded as high as $336.22.
The pullback matters because InterDigital’s business leans heavily on patent licensing, where court rulings and policy shifts can quickly change negotiating leverage and the pace of royalty collections. The company develops and licenses technology used across wireless, video and other markets.
Tuesday’s decline stood out against a firmer tape, with the Nasdaq-100 tracking fund QQQ up about 0.9% at the same time. That left investors scanning for company-specific signals.
A Form 144 notice filed late Monday showed InterDigital officer Rajesh K Pankaj proposed selling 1,000 shares, with an aggregate market value of about $326,750, through Morgan Stanley Smith Barney. Form 144 is a required notice of a planned sale under U.S. securities rules, and the filing said the trade was tied to a Rule 10b5-1 plan, which is a pre-set trading program. 1
Legal developments tied to the company’s licensing battles also remain on screens. Sisvel said in a weekly roundup that the Unified Patent Court’s Mannheim local division has threatened Amazon with sanctions over non-compliance with an earlier “anti-interim licence” injunction — an order aimed at stopping a party from seeking a court-ordered temporary licence while a broader FRAND dispute plays out — and that the court has informed the European Commission of the order.
InterDigital has accused Amazon (AMZN.O) of infringing patents tied to digital video technology in litigation that spans multiple jurisdictions. “Our preference is always to sign licenses through amicable negotiation,” InterDigital’s chief legal officer Josh Schmidt said in a statement at the time. 2
But patent fights are messy and slow, and headline wins do not always translate into faster cash collections. A court-set FRAND rate below investor expectations, or a loss of injunctive leverage, would pressure the stock’s licensing narrative.
