GlobalFoundries sues IBM for allegedly sharing confidential IP and trade secrets with Rapidus, a Japanese chip company that IBM is working with on 2nm chips
Chip manufacturer GlobalFoundries Inc (GFS.O) said on Wednesday it had filed a lawsuit against International Business Machines Corp …
Context & Ripple Effects
GlobalFoundries' lawsuit against IBM is not an isolated spat — it extends a litigation habit that began with the company's 16-patent infringement suit against TSMC in the US and Germany, where it also sought import bans that would have touched Nvidia and Apple chips. The new target is different: not a rival foundry copying process patents, but IBM allegedly passing confidential IP and trade secrets to Rapidus, the Japanese consortium IBM is partnering with on 2nm production.
First-order effects
- IBM and Rapidus now carry litigation risk inside their flagship 2nm collaboration — every technology transfer between them becomes subject to claims that it crosses GlobalFoundries' confidentiality boundaries.
- GlobalFoundries converts its trade secrets into an active defensive asset at the exact moment IBM is trying to commercialize them through a state-backed partner.
Second-order effects
- IBM must weigh whether to keep transferring 2nm know-how to Rapidus while the dispute is live, slowing the very partnership that gives Japan a second advanced-node champion.
- Other companies licensing IBM semiconductor work gain a template for auditing what IBM shares downstream, and Rapidus' government backers face pressure to show their program can survive legal friction with Western incumbents.
Third-order effects
- As countries fund national chip consortia to catch up at leading nodes, incumbents increasingly answer with trade-secret litigation rather than price competition — and GlobalFoundries' own settlement of the dueling lawsuits with IBM two years later suggests these disputes tend to end in negotiated truces rather than injunctions, making lawsuits an opening bid in commercial bargaining.
The trend: Government-backed entrants like Rapidus are pushing into leading-edge manufacturing through partnerships with legacy labs, and incumbents are responding with trade-secret litigation that functions as leverage in eventual settlements.
