Developing Story
VLSI Technology v. Intel – CAFC Reversal of Noninfringement Rulings (2026)
The Federal Circuit issued a precedential ruling reversing Intel's summary judgment win in VLSI Technology's multi-core chip patent case, reinstating both infringement claims and a previously excluded damages expert. The decision strengthens patent holder leverage in semiconductor architecture disputes and signals continued Federal Circuit scrutiny of district court summary judgment and Daubert rulings.

## VLSI Technology v. Intel – CAFC Reversal of Noninfringement Rulings (2026)
### Overview
The U.S. Court of Appeals for the Federal Circuit (CAFC) issued a precedential decision partially reversing Intel's summary judgment of noninfringement in litigation brought by VLSI Technology, in an opinion authored by Chief Judge Moore (IPWatchdog, April 14). The ruling reinstates VLSI's infringement claims regarding a multi-core system-on-chip patent and reverses the exclusion of a damages expert.
### Key Facts
- The CAFC issued a precedential decision authored by Chief Judge Moore (IPWatchdog, April 14)
- The Northern District of California had granted Intel summary judgment of noninfringement of VLSI's U.S. Patent No. 8,566,836 ('Multi-core System on Chip') (IPWatchdog, April 14)
- The district court also struck damages theories from one of VLSI's experts (IPWatchdog, April 14)
- CAFC reversed on both noninfringement and the damages expert exclusion (IPWatchdog, April 14)
- The decision is designated precedential, giving it broader significance beyond the parties
### Legal Significance
- **Precedential status**: The ruling will bind future Federal Circuit panels on the legal issues addressed, likely relating to claim construction and/or summary judgment standards in multi-core chip patent cases
- **Damages expert reinstatement**: Reversal of expert exclusion is significant — it suggests the district court applied too strict a Daubert standard
- **Chief Judge Moore authoring**: Moore's authorship signals the CAFC views this as a significant case warranting senior attention
- VLSI is backed by SoftBank-affiliated entities and has been one of the most aggressive patent assertion campaigns against Intel in recent years
### Strategic Implications
- Intel faces renewed liability exposure across its multi-core processor product lines
- The precedential ruling may embolden other patent holders asserting chip architecture patents
- Connects to the broader 'enforcement asymmetry' trend favoring patent holders at the Federal Circuit
- Intel's ongoing financial difficulties make large royalty exposure particularly significant
### Open Questions
- Damages quantum on remand
- Whether Intel will seek en banc rehearing
- Impact on Intel's other pending VLSI-related litigation
